Infrared sauna - good and bad
Among the many health-improving facilities that use heat, a new infrared sauna has appeared. Despite its "young" age - 10 years from the date of invention, it has already gained immense popularity among the population.
What is its difference from the usual steam sauna, what is its effect on the human body and can the sauna harm health? So, an infrared sauna, good and bad.
What is an infrared sauna
Standard IR sauna is a cabin made of natural wood or other environmentally friendly material. In the walls and under the seats infrared emitters are mounted. Very popular individual booths, where you can learn the charms of a thermal procedure alone, as well as thermal cabinets, accommodating up to 5 people.
IR radiation sources for saunas are special ceramic heaters, powered from the network. Due to the radiated heat, they provide warming of tissues to a depth of up to 4 cm. Heat transfer occurs due to electromagnetic waves of the infrared range without using any transmitting medium (air, steam). They are absolutely safe, because they represent the natural heat emitted by any heated bodies. And the length of their waves, corresponds to those that emits a human body (0.76-3 microns).
Unlike the sauna and the usual sauna in its IR variety, energy is wasted to warm up the air, only about 20% of the radiated heaters. And in an ordinary bath - up to 80% of the heat energy is spent for the same purposes. And only then the heated air gradually warms up the human body. And the heating of tissues in a regular sauna occurs at a depth of only a few millimeters.
Benefits of IR saunas
The benefits of IR saunas are manifested from the first minutes of the visitor's stay, expanding the pores and causing profuse sweating. Streams of abundantly flowing sweat are 20% composed of harmful substances - toxins and wastes. Getting rid of them cleanses the body, charges it with energy.
The temperature of 38.5 ° C, to which the body heats very quickly, is disastrous for most microbes and viruses. The life-giving heat warms up the muscle and bone tissue, accelerates the movement of all liquid components.
Let's study in detail how useful infrared sauna. When the infrared procedures are systematically applied:
- lower cholesterol, which reduces the risk of cardiovascular pathologies and stabilizes blood pressure;
- eliminates the fragility of the vascular walls;
- the immune system is activated;
- removes muscle, joint and headaches;
- acceleration of wound healing and bruising;
- stress conditions are restored, sleep is restored;
- the nasal congestion is eliminated and other chronic ENT diseases are cured.
Even a cursory glance at this list allows us to conclude not only about health-improving, but also about the curative effect of infrared waves.
However, the effect of an infrared sauna is not limited to this. Her visit has a wonderful rejuvenating effect and a noticeable cosmetic effect. Indeed, opening pores and profuse sweating contribute to deep cleansing of the skin, clearing of dirt and dead cells.

Nutritional creams, applied after the end of infrared procedures, enhance the cosmetic effect of visiting the sauna.
Very effective IR procedures for weight loss. Sweating is accompanied by a significant expenditure of energy. Plentifully allocated sweat for one session in a sauna takes with itself as much energy, how many a 10-kilometer run. If the sauna is combined with a reasonable diet, then parting with excess kilograms you are provided.
A number of skin diseases (dermatitis, eczema, acne and acne, dandruff) - are successfully cured when visiting an infrared cabin.
Hateful cellulite in the form of a "lemon peel" is very uncomfortable under the sights of infrared radiation. These subcutaneous deposits, consisting of fat, water and slags begin to resolve.
Excellent IR sauna affects professional athletes. Her visit before training helps to warm up the muscles, prepare them for increased stress. During exercise, lactic acid accumulates in the muscle tissue. From its level, and depends on the degree of fatigue athlete. Sauna after a workout for half an hour reduces this level 2 times.
The excellent therapeutic and cosmetic effects of directional heat flux become noticeable with the regularity of these sessions. But, how often can I visit an infrared sauna?
Small size and ease of operation allow you to install an infrared sauna in an apartment or a country house. And a half-hour stay in this individual "health-improving center" is easier to transfer than in a regular sauna.
To get the most out of this thermal procedure, you should follow some rules.

The recommended frequency of visiting an infrared sauna is no more than twice a week. The health course should include 11-12 sessions. If the purpose of your procedures is weight reduction, you can steam more often, say in 1-2 days, and after classes on simulators or other physical exertion. Excellent results can be obtained while using other methods of weight loss (massage, wrap, appropriate diet).
In general, listen to your well-being, look for the "golden mean", which will allow you to determine the maximum time spent in the sauna, and the frequency of its visit.
