The main way that an infrared sauna helps in boosting your immune system is by burning off sick and dead cells as well as bacteria. This is because sick and diseased cells have a lower resistance to heat. When sitting in an infrared sauna for an extended period of time, your core body temperature will rise 2-3 degrees (getting very close to 100 degrees °F. When this happens it further weakens these already weakened cells. Due to the hyperthermic rise in temperature, your white blood cell count will rise. This then allows these extra white blood cells to go out and kill the weakened cells and destroy bacteria. As a result, your immune system is boosted (this is also why your body gives itself a fever when fighting a cold or flu).
There are also a few other steps you can take to bolster your immune system.
1) Eat Right
It is so important to consume the correct immune fighting foods while attempting to stay healthy. Besides drinking plenty of water, adding more vegetables to your daily intake is added insurance in the fight against a cold or flu. Plant based foods provide immense protection from free radicals as well as assisting in boosting your immune system. These foods include vegetables, nuts, legumes and fruit.
2) Exercise in Moderation
By using your sauna you will also experience passive aerobic exercise. A session in one of our saunas mimics a cardio workout, which in turn increases blood flow, thus aiding in boosting immunity, oxygenating your blood and ridding toxins through perspiration. The immune boosting benefits from a daily sauna also include improved circulation and detoxification.
3) Proper Rest and Stress Reduction
If you are unable to exercise on a given day and experience stress due to everyday living, another way to ignite your immune system is to take a 20-30 minute sauna session. Besides receiving the benefits of passive aerobic exercise, a session in the infrared heat reduces stress levels. Most illnesses are related to some form of stress on the body; whether physical, mental or both. Chronic stress affects everything and decreases your immune system. Infrared therapy is not only relaxing, it assists in reducing stress. This is done by taking your body out of the sympathetic nervous system response (the fight in the ‘fight or flight’ analogy) and you then go into the parasympathetic nervous system response. This will lower your blood pressure and allow you to relax. Your body cannot repair itself without rest and one of the best benefits of infrared therapy is very deep sleep.
