Infrared Sauna

An infrared sauna is a method of people who want to have a good health. Infrared sauna uses far infrared that radiate the thermal energy or heat to the human body. , unlike traditional saunas which heat the body indirectly via air or steam. However, Infrared sauna will be danger if a person who absorb the thermal energy in a along time. But Infrared sauna gain more advantage.

Health benefit claims

A study of patients with rheumatoid arthritis and ankylosing spondylitis showed a reduction in pain, stiffness and fatigue during infrared sauna therapy,

"but these did not reach statistical significance".[1]

Infrared (IR) light is electromagnetic radiation with a wavelength between 0.7 and 300 micrometres, which equates to a frequency range between approximately 1 and 430 THz.
Its wavelength is longer (and the frequency lower) than that of visible light, but the wavelength is shorter (and the frequency higher) than that of terahertz radiation microwaves. Bright sunlight provides an irradiance of just over 1 kilowatt per square meter at sea level. Of this energy, 527 watts is infrared radiation, 445 watts is visible light, and 32 watts is ultraviolet radiation.


Humans at normal body temperature radiate chiefly at wavelengths around 12μm (micrometers), as shown by Wien's displacement law



Photobiomodulation

Near infrared light, or photobiomodulation, is used for treatment of chemotherapy induced oral ulceration as well as wound healing. There is some work relating to anti herpes virus treatment. Research projects include work on central nervous system healing effects via cytochrome c oxidase upregulation and other possible mechanisms.

The infrared divided in three regions: Near Infrared, Mid Infrared and Far Infrared. Applications of each region are different.

Sauna
A sauna is a small room or house designed as a place to experience dry or wet heat sessions, or an establishment with one or more of these and auxiliary facilities.

A sauna session can be a social affair in which the participants disrobe and sit or recline in temperatures of over 80 °C (176 °F). This induces relaxation and promotes sweating.

Saunas can be divided into two basic styles: Conventional saunas that warm the air or infrared saunas that warm objects. Infrared saunas may use various materials in their heating area such as charcoal, active carbon fibers, and other materials.

Infrared saunas use infrared heater emit the thermal energy to warm the body without raising the ambient temperature and raising the temperature in the shot time than conventional saunas

So, the development of saunas technology is Infrared sauna.[4]

How Do Infrared Saunas Work?

How Do Infrared Saunas Work?

By Adriana N.

In recent years, the popularity of saunas has significantly increased due to its numerous health benefits and its ability to help one relax and reduce stress. Infrared Sauna is one type of sauna that is becoming well known for its positive health impact on the mind and body.

An infrared sauna is different than a conventional sauna as it does not use steam. Instead, it utilizes special heaters that produce and disperse infrared rays. Infrared light is a wavelength of light naturally emitted by the sun. Infrared saunas produce the same infrared energy we get from the sun, but it is not harmful ultraviolet light. Infrared is thermal radiation, meaning that it conducts heat. The electromagnetic energy enters the body and causes it to heat up which results in sweating.

Ceramic heaters are used in modern infrared saunas. The temperature created ranges from 110 to 130 degrees F. It is cooler than a traditional sauna which allows one to sit in the sauna longer thereby perspiring more. The infrared radiation only heats the body, and not the air. The heating effects are produced below the skin and the deep penetration of the infrared rays into the skin allows more contaminates to be removed than if one were to use a conventional steam sauna.

Infrared rays have shown to be beneficial to the body. The harmless rays enter skin and the heat produced will cause fat cells to loosen up resulting in toxins, metals, and other harmful elements being released. As one perspires, toxins, bacteria, and metals, are driven out from the body which makes infrared saunas an effective method of body detoxification. Once one eliminates the harmful substances from their body, they will have more energy, be more alert, and have an overall feeling of good health. They will even sleep much better.

Infrared saunas are also effective at clearing up acne. As well, it helps to reduce cellulite, improves skin elasticity and tone, and even helps to heal such conditions as burns, eczema, scars, and psoriasis. In fact, for those interested in shedding some extra pounds, infrared saunas can burn 400-600 calories in one 30 minute sitting.

Infrared saunas are also an effective therapeutic technique for relieving muscle pain and spasms, as well as speeding up the healing process for injured muscles and tissue. The heat that is produced warms up the body internally which boosts blood circulation and brings oxygen and nutrients to the injured area and removes fluid build up from the area. As well, the deep penetration of the infrared rays is an effective method of treating bone and joint conditions such as osteoarthritis. The healing properties and its stress alleviating effects makes this type of sauna a good choice for those wanting to improve their overall health and well being.

The health benefits for both the mind and body have made saunas a popular choice for the home as well as in wellness spas. Regular use of an infrared sauna will detoxify the body of harmful chemicals, metals, bacteria, and other toxins from the environment, and one will soon achieve healthy weight loss, a strengthened immune system, and most importantly, good health.

Infrared saunas offer many health benefits. It removes the secreted toxins, allowing your body to feel rejuvenated. Considering purchasing sauna heaters, visit us today!

Energy expenditure controversy

Some infrared sauna proponents claim that the sauna is an effective method for considerably raising the rate of energy expenditure in the body. Proponents typically quote the Journal of the American Medical Association stating:

"A moderately conditioned person can easily sweat off 500 grams in a sauna, consuming nearly 300 kcal, which is equivalent to running 2–3 miles. A heat-conditioned person can easily sweat off 600–800 kcal with no adverse effects. While the weight of the water loss can be regained by drinking water, the calories consumed will not be.".

This statement is based on the amount of energy absorbed by sweat evaporating from the skin. It is equivalent to the latent heat of vaporizaton of water, which is 539 kcal/kg (2260 kJ/kg). The source of this energy is then confused to be body energy stores, while the source is in fact the excessive heat absorbed from the sauna. The body reacts to the excess heat flux by increasing perspiration. This does not increase body heat generation and calorie burn.[1]

Risks and Benefits of saunas

Health risks and benefits

Saunas can also be dangerous due to the risk of heat prostration or the even more serious hyperthermia. Children and older persons who have heart disease or seizure disorders or those who use alcohol or cocaine are especially vulnerable.

Prolonged stay in a sauna may lead to loss of electrolyte from the body, the same as after rigorous exercise. Risks of dehydration leading to heat stroke in more sensitive individuals can occur and may be reduced by regular sipping of water or isotonic drinks, but not alcohol, during the sauna. Sauna bathing and heavy drinking of alcoholic beverages, and also sauna bathing during alcohol withdrawal (hangover) phase can undoubtedly create real health risks.

Many of the sauna therapeutic trials used a regular schedule of at least 5 days a week and often daily for one to three months, then several times a week for extended periods.

In some countries the local gymnasium is usually the closest and most convenient and some pool, major sport, or even resort complexes also contain a sauna. Therapeutic Sauna is often carried out in conjunction with physiotherapy or hydrotherapy, gentle exercises within the capability of the person without exacerbating symptoms.[3]

Benefits

Contraindications to sauna include unstable angina pectoris, recent myocardial infarction, and severe aortic stenosis. Sauna is safe, however, for most people with stable coronary heart disease. It is not harmful to the aged when used in moderation, is safe even for young infants over 3 months if limited to short [less than 3 minutes] sessions , and does not affect wound healing .

Sauna use may reduce the incidence of the common cold, and temporarily relieve the symptoms . It increases performance in endurance sport, increases plasma volume and red cell volume in athletes, decreased systolic blood pressure, significantly improved exercise tolerance, increased peak respiratory oxygen uptake, and enhanced anaerobic threshold in chronic conditions.[3]
