How does Sauna works?

It has been about more than a week since I have updated this blog. So today, I'm going to share with you (Readers ^.^) about how does a Infrared Sauna and Steam Sauna works!

From the name Infrared Sauna, we can imply that the sauna actually uses infrared to operate.

From the scientific point of view, infrared ray is a form of electromagnetic spectrum, which has a wavelength of 5.6-15µm. As the wavelength is close to human body's radial which allows the body to absorb easily. 

The far infrared ray can penetrate 40mm deep into the human skins, so the recipient can receive an infrared massage, making cell tissues resonant, accelerate blood circulation and eliminate the impurities , result in both bio-thermal effect and physical effect. Thus, health will be improved.

From the image above, we can clearly see that the blood vessels are just beneath the skin, hence, the infrared can definitely reach the blood vessels as well as the tissues beneath your skin. 

Moreover, the infrared ray is able to penetrate through our skin and stimulates the movement of molecules in our body. When this happens, water (sweat) along with other toxins in our body will be washed out. 

So, do we all have a clearer idea of how does an infrared sauna works? 

I hope it's a yes! Otherwise, SingSauna.com is able to provide you with more information! 

Now, lets head over to how does Steam Sauna works!

For many of us, we find it hard to imagine burning charcoal, putting water over the fire to get steam and enjoy the steam! Many would consider this as the conventional type of sauna. True enough, these types of conventional sauna is dated back to hundred years ago! 

When the charcoal burns and water is added, the steam that is produced will usually rise. From the theory of physics, we know that hot air will rise and cool air sinks. However, the area where the user is seating is at the lower part of the sauna, hence, it takes a longer time to sweat in a conventional sauna than in infrared sauna! 

Now we can conclude which Sauna is better? :)

Carbon Fiber Heater

Hola Readers!

Today, i am back to talk to you about my favorite sauna, which is also the sauna that i have at home. From the title itself, you can see that it is actually called Carbon fiber heater.

It looks something like that that. Pretty cozy as it can fit at most 2 person. Usually, it's more for single user, whereby sometimes we called it, personal sauna. 

Many times, people would ask me what is so good and special about this particular sauna. One thing that i love most is definitely because it is cozy! I can lie on the bench, read book, listen to my favorite songs and sweat all the toxin out! It definitely feel like you're having the best moments! 

Other features would include:

• Organic carbon: Human body is made up of carbon and water, so the spectrum from carbon fiber heater is easier to be absorbed by people
• No Wires Heater: Ultra-conducive carbon fiber heater brings more efficiency and longer life
• 360° Surrounded Heater: makes people enjoy the therapy of far infrared completely
• Low surface temperature:  More propitious to emit biology far infrared rays

In my previous post, i have mentioned about the benefits of sauna. However, no harm posting again and refreshing you memory again about the benefits of sauna? 

As for myself, i think that the most important benefit that you can get from a sauna session is actually the fact that during a sauna session, it can help your body to expel toxins!

How is that possible? 

For people who knows a bit of biology, sweat actually contain urea and waste product, which can also be called as toxins. Hence, whenever we sweat, we can actually sweat out toxins and waste products. 

Are you stress? 

Because having a sauna session helps to loosen muscle and relax the body. Moreover, it has been known that a sauna session provides a thorough and more effective treatment than a massage! 

Going for facial and treatments just to reduce wrinkles and have a softer skin? 

How about having a second thought about what a sauna session can do for you? 

Infrared heat can actually improve circulation, dead skin and dirt chemicals from the surface of your skin. This will then help to reduce wrinkles due to aging and hence, lead to a softer and finer complexion. 

Control weight? What's another alternative of having to exercise? 

Answer: SAUNA!

Y up, that's right! A sauna session can actually help to make you reduce weight! The whole sweating process will actually increase the cardiac output, heart rate and metabolism rate. This process requires huge amount of energy and reduces excessive moisture, sweat and subcutaneous fats in the body. Moreover, because the body would need energy to sweat, fats would be burnt to give the body energy, and hence, the loss of weight. In addition, fats become soluble at 42°C, whereby the body can sweat out both toxins and fat at the same time. 

The previous post, i mentioned that my mum had a sauna session and after the session, all her ache is gone? 

Here's why:

Due to infrared heat, our blood vessels will expand, resulting in better circulation. Better circulation will allow more oxygen to reach injured parts, help reduces pain and speed up the healing process. 

Thus, aches and pain will not be felt after each sauna session, isn't it amazing?

Muscle spasms, arthritis and rheumatism are being treated with Sauna and have been proven successful! 

Falling sick all the time? 

Sauna session can actually help one to improve their immune system! 

Far infrared heat therapy provides an artificial fever to the body, whereby it will eliminate virus and attack foreign agents. Moreover, recent studies have shown that cold and flu-like illnesses can be drastically reduced if treated in the early stages by Far Infrared heat therapy. 

Alright, what do you think of Infrared sauna? A whole new different perspective? Come on board with us, have your own personal sauna at home, and enjoy sauna session anytime you want!

It's all about Sauna

Aloha Readers!
It has been a long time since i have updated my post? Yup, so now, let me bring you through some of the wonderful things about Sauna.

As for me, i don't really go to sauna much and my experience with sauna is actually pretty limited. However, my mum, loves and adore sauna so much! Well, she is a sales manager and do have to attend to customer everyday and she have to stand the whole day. Moreover, in a air-conditioned environment, it is pretty difficult to sweat. As you know (from my previous posts), they toxins will accumulate in our bodies and one of the ways to get these toxins out is by sweating.

As we all are busy with work and pretty much lazy to get out of bed in a Sunday morning just to go out for a jog, sauna can be a very good substitution for jogging! Sauna, sometimes can be called as artificial sweating. Yes, maybe. It can let you sweat even when you're just sitting there doing nothing, Sauna let you sweat! This is the amazing thing about Sauna.

After work, my mum is exhausted and has aches everywhere! So i suggested to here that we go for a sauna session. We don't have to travel far, because the sauna is just beside our bathroom! How convenient is it?! Once we get home, we get undress and step into the Sauna and start reading magazines and have listen to soothing music.

We used infrared sauna, whereby there is no steam nor water needed. So long as the sauna is on and you're present in the sauna, you'll definitely sweat! About 10-15mins, me and my mum starts to sweat profusely. Then, we lower the sauna temperature and we starts to cool down. After a cooling bathe, both of us felt so refresh and my mum no longer feel any ache anywhere!

Interestingly, as compared to jogging and exercising, having a sauna session actually help us to sweat more! The only disadvantage of going for sauna than exercising is that exercising will help one to build up muscle while sauna can't. HAHA!! XP

Alright, i'll stop here for this week. Next week, i'll update you on one of my favorite sauna! Be back for more! :P

Wanting to get a private sauna at home?

Individual Sauna? Personal Sauna?

Coming up soon!

Traditions and old beliefs

One word in Finnish, strictly connected to sauna, is löyly. Steam vapor, also called löyly [ˈløyly], was created by splashing water on the heated rocks. In many languages related to Finnish, a word corresponding to löyly is found. The same approximate meaning is used across the Finnic languages such as in Estonianleil. Originally this word meant "spirit" or "life", as in e.g. Hungarian lélek and Khanty lil, which both mean soul, pointing to the sauna's old, spiritual essence. There still exists an old Finnish saying, "saunassa ollaan kuin kirkossa," – one should behave in the sauna as in church.

The same meaning of "spirit" is also used in Latvian.

Saunatonttu, literally translated the sauna elf, is a little gnome or tutelary spirit that was believed to live in the sauna. He was always treated with respect, otherwise he might cause much trouble for people. It was customary to warm up the sauna just for the tonttu every now and then, or to leave some food outside for him. It is said that he warned the people if a fire was threatening the sauna, or punished people who behaved improperly in it – for example slept, or played games, argued, were generally noisy or behaved otherwise "immorally" there. Such creatures are believed to exist in different cultures. The Russian banya has an entirely corresponding character called a bannik.

In Thailand, women spend hours in a makeshift sauna tent during a month following child birth. The steam is typically infused with several herbs. It is believed that the sauna helps the new mother's body return to its normal condition more quickly.

Fun Fact- Heating and Cooling the Inner Body

Marvelous things happen beneath the skin in the heat of the sweat bath. The capillaries dilate permitting increased flow of blood to the skin in an attempt to draw heat from the surface and disperse it inside the body. The bather's skin becomes cherry red. The heart is pressed into a faster pace to keep up with the additional demands for blood. Impurities in the liver, kidneys, stomach, muscles, brain, and most other organs are flushed out by the faster flow of juices. The skin and kidneys filter the wastes, excreting them in sweat and urine.

Some researchers claim that the rapid flexing of the heart and blood vessels in the heat of the sweat bath is a healthy exercise that puts little more strain on the heart than strolling on level ground. The increased capillary volume, they say, keeps blood pressure normal.

While the surface temperature of the skin may rise as much as 1O degrees C, inner temperature increases up to 3 degrees C. It is a common knowledge that many bacterial and viral agents do not survive well at temperatures higher than normal body temperature. It is also possible that damaged cells repair themselves quicker in fever conditions due to the increased metabolic rate. Recovery from illness then comes easier and quicker.

The inner temperature rise also affects the function of important endocrine glands, the pituitary in particular. Located in the bottom center of the brain, the pituitary is known as the master gland because its hormones regulate both metabolism and the activity of other glands such as the thyroid, adrenal, ovaries and testes. Urged by the heat, the pituitary accelerates the body's metabolism and affects the interplay of several of the body's hormones. Some people have gone as far to say that sex drive is increased and growth stimulated in the sauna bath.
The oxygen needs of the body increase by about 2O percent so the lungs, another important eliminator of body wastes, join in the body's quickened pace. Clogged respiratory passages are opened by heat, giving relief from colds and other minor respiratory problems. Sweat bathing is not recommended for those suffering from pneumonia or other acute respiratory diseases.

When the bocly is slowly cooled, the effects of heat are reversed--the heart calms, sweat pores close, dilated blood vessels contract and body temperature returns to normal. On the other hand, abrupt cooling brought on by a plunge into snow or icy water creates a more dramatic effect. For this reason, people with weak constitutions should avoid rapid cooling. Vessels near the skin's surface contract, but since the skin's metabolism returns to normal slower than the circulatory system, wastes accumulate that are normally washed out by the blood. Local vasodilators are then stimulated and blood rushes back to the skin's surface. The heart continues to beat vigorously and you may experience psychedelic flashes bouncing across your retina from the increased adrenal activity--an unforgettable experience! Goose bumps sometimes appear, a phenomenon reminiscent of the time when our prehistoric ancestors possessed a shaggy pelt of hair. Goose bumps extended the hair, making it thicker and giving more insulating power against cold or protection from attack. The swift transition from hot to cold stimulates the kidneys and usually creates the desire to urinate.

The typical body is 6O% water by weight and any pounds lost at this point will be promptly regained. As you can imagine, the combination of sweat bathing and cooling conditions the body, and a well-tuned body is more resistant to colds, disease and infection. In cold weather, the warm glowing feeling lingers for hours, while in hot climates the body seems cooler than before the sweat bath.

Fun fact - Skin

Because it eliminates, the skin is sometimes called the "third kidney." It is far more complex than the kidney or any other organ except the brain. It is composed of blood vessels, nerve endings, vessels for carrying Lymph, pigmentation, oil glands, hair follicles, cells that are waterproof and deny entry of bacteria and, of course, the tubular, coiled sweat glands. It is so important that death by accumulated poisons occurs in a matter of hours if the skin, and its sweat passages, is smothered.

A Finnish doctor wrote: "The best-dressed of foreigners can come into a doctor's office, and when his skin is examined, it is found to be rough as bark. On the other hand, as a result of the sauna, the skin of any Finnish worker is supple and healthy." Properly cared for skin is better able to resist eczema, athlete's foot, pimples and blackheads.

Furthermore, combining sweat bathing and brushing with a loofa or rough brush removes flakes of dried skin cells that accumulate on the epidermis. If allowed to remain, they can clog sweat pores and oil passages and result in dry, flaky skin.

In conjunction with the sweat bath exercise, supplemental dosages of vitamins B2 and E help keep skin fresh. Cayenne pepper, ginger, peppermint are notable herbs which, when taken internally, promote sweating and healthy skin.

(An interesting note: the ability of lizards and snakes to shed old skins has fascinated many primitive societies. Some believe that if they could shed their old skins and acquire new ones, they could renew their youth. During some ceremonies, participants don the skins of animals or other human beings in a symbolic gesture of eternal youth.)

Fun fact - Sweat

Sweating is as essential to our health as eating and breathing. It accomplishes three important things: get rid of wastes in the body, regulates the critical temperature of the body at 37 degrees C (98.6 degrees F), and helps keep the skin clean and pliant.

Many people, in this sedentary age, simply don't sweat enough, making sweat bathing particularly desirable. Antiperspirants, artificial environments, smog, synthetic clothing, and a physically idle lifestyle all conspire to clog skin pores and inhibit the healthy flow of sweat.

[The length of time spent in the sauna differs from time spent in other types of sweat baths. In this section, results peculiar to the sauna are noted.]

When you lounge in a sweat bath, heat sensitive nerve endings produce acetylcholine, a chemical which alerts the 2.3 million sweat glands embedded in the skin. But not all of them respond. The apocrine sweat glands, located in the pubic and arm pit areas, are activated only by emotional stimuli. They carry a faint scent whose purpose is believed to arouse the sex drive.

Nevertheless, the eccrine sweat glands, by far the most abundant, respond to heat. During a 15-minute sauna, about one liter of sweat is excreted, depending upon the individual. (Normal daily rate ranges from .5 to 1.5 liters.) Eccrine sweat is clear and odorless; any odor is only created by the presence of bacteria. One of its chief functions is to cool the body by evaporation, although there are also eccrine glands on the palms of your hands and soles of your feet which react to emotional stimuli. It is believed that these sweat glands were intended to provide us with a good grip on clubs, rocks or vines when our survival often depended upon them. Sweat glands on the feet provided greater traction when it came time to run.

Another kind of sweat, called insensible perspiration, originates inside and works its way through blood and other cells to the surface of the skin. Even without a sweat bath, approximately a liter of insensible perspiration evaporates each day.

A modified type of sweat gland is the milk-producing mammary gland. Some mothers in Finland believe the sauna encourages the breast's ability to produce milk, although this hasn't been established scientifically.

Sweat also has the function of being a judicious garbage collector. During a 15-minute sauna, sweating can perform the heavy metal excretion that would take the kidneys 24 working hours. 99% of what sweat brings to the surface of the skin is water, but the remaining one percent is mostly undesirable wastes. Excessive salt carried by sweat is generally believed to be beneficial for cases of mild hypertension. Some mental hospitals use saunas in their rehabilitation programs to pacify patients.

A metabolic by-product, urea, if not disposed of regularly, can cause headaches, nausea and, in extreme cases, vomiting, coma and even death. Sweating is such an effective de-toxifier that some physicians recommend home saunas to supplement kidney machines. Sweat also draws out lactic acid which causes stiff muscles and contributes to general fatigue. Sweat flushes out toxic metals such as copper, lead, zinc and mercury which the body absorbs in polluted environments.

Did you know? ...

Sitting in a sweat bath could be the most vigorous activity you've had all day. The heat produces an artificial "fever" and urges every organ of the body into action. While outwardly relaxed, your inner organs are as active as though you were jogging or mowing the lawn. At the same time, you are being cleansed from inside out by the skin, your body's largest organ and its excretion, sweat.

The oldest know medical document, the Ayurveda, appeared in Sanskrit in 568 BC and considered sweating so important to health that it prescribed the sweat bath and thirteen other methods of inducing sweat. Throughout history physicians have extolled the medicinal value of the sweat bath in its various forms such as the Finnish sauna, Russian banai, Islamic hammam, or the American Indian sweatlodge. Today, enthusiasts claim that beyond being relaxing the sauna gives relief from the common cold, arthritis, headaches, hangovers and "just about anything that ails you." Even if these claims are somewhat exaggerated, medical evidence shows that bathing in temperatures of 9O degrees C (192 degrees F) has a profoundly beneficial effect on a healthy body.

Tips to get the most out of your Sauna Experience

• Avoid staying inside any sauna for longer than 30 minutes.
• Be sure to properly hydrate with fresh, pure water before and after taking a sauna and if you are sweating profusely, you will want to consider replacing your electrolytes with something like Himalayan salt.
• Take the sauna with a family member or close friend, or make sure someone checks on you every so often.
• If you have any kind of ailment or are sensitive to heat, check with your healthcare professional prior to partaking.
• Far-infrared emitters do not work through clothing. So, disrobe as much as possible to optimize the heating and sweating effects.
• Work up to regular use over time. You don't have to take a 20 minute sauna from the get-go. Start slowly to build up an acceptable comfort level.
• Try to remain relaxed, quiet, and reflect on positive emotions. Listening to some soothing background music may help you unwind and relax.
• When finished, take a shower, warm or cool, but not hot. Avoid using soap as you're already clean and soap tends to clog your pores. Wash off your sweat with a skin brush or loofa.
• After showering, sit or lie down for at least 10 minutes for final reflections on your sauna experience.

The top 10 Precautions when using a sauna

• Anyone under the influence of drugs or alcohol should stay clear from the Sauna.  Alcohol dehydrates the body and using the Sauna would dehydrate even more. Also you are not using your best judgment when under the influence.

• Persons with low blood pressure or heart disease should exercise caution. The heat of the Sauna causes the capillaries in the skin to dilate, which in effect lowers blood pressure. Heartbeat increases to keep blood pressure normal. Use caution and pay attention to how you feel before and after a Sauna.

• Children should be supervised in the Sauna. Children in Finland start enjoying the Sauna at a very young age. It is best to start a child at a lower temperature or have them sit on the lower bench where it is cooler.

• Sauna is a wonderful and relaxing experience of cleansing the body and can be enjoyed by most people. Again, it is best to check with a physician if you have any medical conditions or feel any adverse effects. Most of all, the Sauna is a matter of common sense. Your body will let you know when it is time to exit the Sauna if you get too hot. Remember to drink plenty of water or other fluids after the Sauna to replace what you have lost.

• Remove jewelry and glasses before entering the sauna. Metal will get burning hot, and heat causes capillaries and skin to swell making rings and tight bracelets constricting. Contact lenses may dry and provoke eye irritation–pop them out before sweat bathing. 

• Eating before sweat bathing puts a strain on the circulatory system. If one had a heavy meal, do not have a sauna session for at least 4 hours.

• As before swimming, wait an hour or two after a large meal before entering a sweat bath. Also, it is best not to bathe on an empty stomach. Sauna session, like any exercise, uses energy and some people in a depleted condition may experience nausea or even fainting. Settle for lower temperatures and shorter bathing sessions. It is also sensible to avoid sweat bathing when you are physically exhausted or after a long illness. Mental exhaustion is not included in this caution. Finnish students traditionally recuperate in the sauna after the year's final exam.

• Do NOT use the sauna if you are undergoing medical attention, without the prior consent of your doctor.

• Do NOT use the sauna if you are pregnant, suffering from a heart disorder, have abnormal blood pressure or circulatory problems, are a diabetic, suffer from excess fluid retention, have a skin disorder that may be aggravated by heat or humidity, are suffering from a skin infection, have an open wound or have a respiratory disorder {e.g. cough, cold or flu}, unless otherwise advised by your doctor.

• Do NOT stay in the sauna for more than 10 minutes. If you wish to return to the sauna, allow a suitable rest period of at least 5 minutes. Total time in the sauna should not exceed 25 minutes – 10 minutes in the sauna, 5 minutes rest, 10 minutes in the sauna.

How to use a sauna

1.   In general, you need 2 hours, 2 large towels (1 to dry yourself, 1 to lie down on), bathing shoes and soap.
2.   Always take a shower before using the sauna - for hygienic reasons and to remove the greasy film on your skin, which delays the sweating process.
3.   You have to be dry when going into the sauna (wet skin prevents sweating).
4.   It’s recommended to prepare yourself for the heat with a warming foot bath (3-5 minutes).
5.   Please be quiet inside the sauna.
6.   Please always sit or lie on a large enough towel (so that there is enough room for your feet).
7.   In case you lie down in the sauna, you should sit up straight for the last 2 minutes and play with your legs to enhance your blood circulation so that the blood doesn’t drop down in the lower body and cause vertigo.
8.   Don’t force yourself to stay. As soon as you feel unwell, leave the sauna immediately. Your health is always the most important thing.
A sauna bath takes between 8 and 12 minutes, 15 minutes maximum. After that time you should leave the sauna.
9.   After the sauna, go into the fresh air for app. 2 minutes to fill up on oxygen and to cool your lungs.
10.   Always take a shower after a sauna round and before using the cold water bath.
11.   To achieve an effect for your health, the cooling process through fresh air and cold water should be strong enough.
12.   After cooling down, it would be good to take a warming foot bath. At the same time, the rest of the warmth inside the body is dissipated and therefore causes the body to cool down. Additionally, this prevents a cold. A warming foot bath in ankle-high water keeps the body from sweating afterwards.
13.   You can use the different relaxing areas for a rest.
14.   Altogether, you should not take more than 3 sauna baths.

Korean Jjimjilbang

Jjimjilbang usually operate 24 hours a day. In front of the entrance, there are the doors titled “men” or “women” and shoes are to be stored using a given key. Once inside, the shoe locker key is to be exchanged with another locker key to store clothes and belongings. Afterwards bathers walk into the gender-segregated bathhouse area and take a shower. Then, it is supposed to be dressed in jjimjilbang clothes (usually a T-shirt and shorts) received with the locker key.

In a bathing area, there are different kind of kiln saunas with a varying themes including a jade kiln, a salt kiln, a mineral kiln: the dome-shaped inside walls of klin rooms are plastered with jade powder, salt and mineral respectively. and a series of kiln with different temperatures ranging from 60 to 100 degrees Celsius. The temperature sign outside the kiln is given before the entrance.

Hygiene
Jjimjilbangs are always kept in a very sanitary condition for the overall health of patrons, and most are cleaned continuously. No harsh chemicals are used in the waters or saunas.

All wet areas prohibit the use of clothing for safety reasons. With the extreme heat of the baths and steam rooms, it is believed that toxic chemicals can leach out of apparel and into the body. It is also believed that if you wear a swimsuit or cover up you may be trying to hide a disease.

The room has walls made of yellow earth bricks and floor covered with jade and is lit with an infrared ray lamp. You can actually sleep in this room, which is separated for men and women. You will feel much more invigorated after sleeping here.

Chamsut Naengbang (Charcoal Cold Room)
Unlike the heat of other rooms, the coolness of the charcoal room is particularly good for stabilizing the mind, relieving stress, and fighting fatigue.

Infrared Sauna

An infrared sauna uses infrared heaters to emit infrared light experienced as radiant heat which is absorbed by the surface of the skin. Traditional saunas heat the body primary by conduction and convection from the heated air and by radiation of the heated surfaces in the sauna room.

Infrared sauna makes the same rays that come from the sun and filters out the UV radiation, so it only gives you the infrared radiation. That radiation that's infrared goes a little bit into your skin so, without heating you up and the external environment too much, it heats the body up.

High temperature helps lower blood pressure and increase blood circulation. "It gets your heart to beat faster, and it burns calories," Dr. Oz says. "It raises your metabolism a little bit, and also when you sweat, you sweat out toxins through the skin."
Quoted from Dr. Oz

Arthritis
A study of patients with rheumatoid arthritis showed a reduction in pain, stiffness and fatigue during infrared sauna therapy, but since results from the study "did not reach statistical significance"  there is no clear or certain relationship between reducing symptoms and using infrared sauna therapy.

Toxins
"Toxins" and "toxicity" are general terms used by alternative health professionals and some doctors to cover a wide range of substances from petrochemicals to heavy metals, which are excreted in very small quantities while sweating, less than 1%.  Proponents of FIR sweating claim a toxin content of up to 15% vs. conventional sweating. Saunas may be useful to those who cannot sweat from exercise due to their health problems.

Heat tolerance
Only if the sauna uses far-infrared technology, the sauna might be more tolerated by patients who don't tolerate the high temperatures of the standard humid hot air saunas. This is because far-infrared rays do not heat the air inside the sauna, but instead they heat the body.

Benefits

Detoxification
Sweating is the body’s safe and natural way to heal & stay healthy. Far infrared sauna benefits the body by heating it directly causing a rise in core temperature resulting in a deep, detoxifying sweat at the cellular level, where toxins reside.

Relaxation
Unlike traditional saunas which operate at extremely harsh temperatures, infrared is a gentle, soothing and therapeutic heat that promotes relaxation and improved sleep. Infrared sauna benefits include therapy that helps you relax while receiving an invigorating deep tissue sweat, leaving you fully refreshed after each session.

Lower Blood Pressure
Infrared saunas induce a deep sweat to make the heart pump faster, which in turn increases blood flow, lowers blood pressure and helps circulation. Scientific evidence shows the infrared sauna benefits user using an infrared sauna a couple times a week lowers blood pressure.

Anti-Aging & Skin Purification
The near infrared wavelength (sometimes referred to as Red Light Therapy) is the most effective wavelength for healing the epidermis and dermis layers of the skin. Near infrared treatments stimulate collagen production to reduce wrinkles and improve overall skin tone.

Cell Health
Near infrared therapy stimulates the circulatory system and more fully oxygenate the body’s cells. Better blood circulation means more toxins flow from the cellular level to the skin’s surface to improve cell health, aid in muscle recovery and strengthen the immune system.

Weight Loss
Studies have shown that benefits of an infrared sauna session can burn upwards of 600 calories while you relax! As the body works to cool itself, there is a substantial increase in heart rate, cardiac output and metabolic rate, causing the body to burn more calories.

Pain Relief
Infrared heat penetrates tissue, joints, and muscles to relieve anything from minor aches and pains to chronic pain conditions such as fibromyalgia. Pain management professionals incorporate infrared heat therapy into treatment plans to decrease pain and muscle spasms and to speed up recovery time.

Improved Circulation
Heating the muscles with infrared rays produces an increase in blood flow similar to that seen during exercise. Regular infrared sauna use—especially in the mid infrared range—can significantly stimulate blood flow up to twice the normal rate.

Wound Healing
Scientific research has concluded that near infrared therapy greatly enhances the skin’s healing process by promoting faster cell regeneration and human tissue growth. Human cell growth increases to repair wounds and prevent infection.

Skin Cleansing 
Sweating helps rinse and cleanse your skin’s epidermal layer and sweat ducts. Cleansing of your pores gives your skin a soft, beautiful appearance.

Better sleep
May help you relax, which may help you fall asleep around bedtime which restores the body and soul.

Steam Sauna

Steam rooms create very good respiratory conditions with the humidity level at 100%. People with coughs and lung problems sometimes use a steam room to soothe their respiratory systems. Steam rooms are also more hydrating for your skin than saunas. This is great for people with dry skin, who might suffer in a dry sauna.
Some people find steam rooms stifling though and think that the humid air is difficult to breathe. Steam rooms have a mystic quality, with the air shrouded in steam, while saunas are clean and clear enough so that you could read a book if you wanted. If you have greasy skin you might find that a dry sauna is better, because your pores may get blocked by moisture if you stay in the steam room too long.

Steam Sauna increase circulation to the surface of the skin and make you sweat, which can be a pleasant sensation and has proven benefits for cardiovascular health. It can also promote a healthy and deep sleep.
Some other benefits include: - clearing of throat, sinus and lung congestion, relief of dry throat and nasal passages and relief from the discomfort of sinusitis.

Salt Sauna

Salt Sauna: Vitamins of the Air

The salt sauna is particularly healing for respiratory and skin conditions.
Salt is a disinfectant that kills almost every virus, fungus or bacterium. If you inhale salty air, the respiratory system is purified of the contagious bodies that may cause illness or generate other diseases. Salty air also helps in improving the physical, chemical and hydrodynamic conditions of the body, resulting in the improvement of peripheral blood circulation, the improvement of the body's resistance and defense mechanism (strengthening the immune system), the termination of certain rheumatic diseases, and the relaxation of the muscles.
Salt therapy works because natural salt has a considerable level of negative charge of its particles. The inner surfaces of human airways have a slight positive charge. Thus, negatively charged particles of the salt are allowed to move into the lumen of the respiratory tract. The heat in the salt sauna releases the negative ions captured within the pure salt blocks, carrying the ions deep into the lungs. In the lungs, tiny chambers (alveolus) fortify oxygen with the negative ions which are then absorbed by the bloodstream to deliver the cleansing and purifying effect to every organ of the body.

Salt rooms and salt saunas are primarily intended for use by patients with respiratory problems (bronchitis, tonsillitis, polypus, bronchial asthma, etc.). However, apparently healthy people are also always exposed to urban diseases like infection by microbes, viruses, air pollution or tobacco poisoning. Some medicines have side effects, but nature never "tricked" anyone. Salt rooms and salt saunas are an effective treatment for diseases like chronic bronchitis, emphysema, asthmatic bronchitis (allergic or infectious), post-rachitic breathing problems or problems with the thoracic cavity, pleurisy, and traces of tuberculosis operation.

Specific effects of salt therapy are:
• Mucolytic (assists in the elimination of excess mucus)
• Antibacteriologic
• Anti-inflammatory
• Immunomodulation (regulates the immune system)

Salt room treatment is recommended for asthmatic diseases, asthmatic bronchitis, chronic bronchitis, allergic breathing, emphysema, hard breathing and bacterial infections.

Treatment: one course lasts 8 - 21 days, depending on the disease.
Treatment takes place in aerosol form.

One treatment lasts 30 minutes to 3-4 hours.

The lung's purification starts 10-14 days after the beginning of the treatment.

Electric stove sauna

The most common modern sauna types are those with electric stoves. The stones are heated up and kept on temperature using electric heating elements. There is thermostat and a timer (eight hour maximum continuous heating time) on the stove. This type of heating is used in urban saunas.

Wood stove sauna

The wood stove sauna is the most common type of sauna outside of the city areas, where the electric sauna is more common. The metal stove with stones on top (kiuas) is heated with birch wood fire, and this heats the sauna room to the required temperature. If birch wood is not available any other wood will do, but well dried birch wood is preferred because of its good quality and smell, and long lasting burn. The important thing is to have a good löyly, that is when the stones are hot enough to evaporate the water thrown on them into steam that rises to the bathers. The bather in every type of sauna sits on a high bench near the ceiling where the hot steam reaches them quickly.

Continuous fire sauna

A continuous fire stove, instead of stored heat, is a relatively recent invention. There is a firebox, a smokestack and stones placed in a compartment directly above the firebox. It takes one hour, to heat up the sauna, which is less time-consuming than the heat storage-sauna. A fire-heated sauna requires manual labor in the form of maintaining the fire during bathing; the fire can also be seen as a hazard.
Fire-heated saunas are common in cottages, where the extra work of maintaining the fire is not a problem.

Heat storage-sauna

The smoke-sauna stove is also used with a sealed stone compartment and chimney (a heat storage-stove) which eliminates the smoke odor and eye irritation of the smoke sauna. A heat storage stove does not give up much heat in the sauna before bathing since the stone compartment has an insulated lid. When the sauna bath starts and the shutter opens, warmth flows into relatively cold (60 °C [140 °F]) sauna. This heat is soft and clean because, thanks to combustion, the stove stones glow red, even white-hot, and are freed of dust at the same time. When bathing the heat-storage, the sauna will become as hot as a continuous fire type-sauna (80–110 °C [176-212 °F]) but more humid. The stones are usually durable heat proof and heat-retaining peridotite (a type of stone). The upper part of the stove is often insulated with rock wool and firebricks. Heat-storing stoves are also found with electric heating, with similar service but no need to maintain a fire.
