Sauna Health Benefits – Why Using A Sauna May Improve Your Health

  • Sharebar

Many enthusiasts claim that sauna health benefits include relief from arthritis, headaches, colds, hangovers and other ailments.

Many claims are true, but there are also many exaggerated claims. Still, there appears to be a good amount of research that proves there are real health benefits you can enjoy from sweating in a sauna.

Sweating & Health

We live in a very sedentary age and many people just don’t sweat enough. That only highlights the importance of using saunas and steam rooms.

Like eating and breathing, sweating is very important for your health. Yep, it’s that important.

Without sweating, your skin pores become clogged up by stuff like artificial environments, antiperspirants, smog, etc.

Many health and wellness professionals agree that heavy sweating in a sauna will help rid your body of harmful waste material.

I’ve even read that some physicians recommend home saunas to supplement kidney machines because sweating is such an effective detoxifier.

Depending on the individual, about a liter of sweat can be excreted during a 15-minute sauna.

Heat Effects On Various Systems & Organs

Kidneys. During sweating, blood is sent away from your kidneys and toward your body’s surface. This can help unburden your kidneys and help purge toxins through sweating.

Liver. Congestion of blood in your liver is reduced while you take a sauna. This may strengthen your liver’s detoxification ability.

Cardiovascular System. During a sauna, both your pulse and stroke volume increase. Surface vessels dilate as blood is shunted from your internal organs to the surface.

Repeated sauna use may help decrease elevated blood pressure by enhancing elasticity of your arteries, removing toxins from your kidneys and helping to reduce excessive sympathetic nervous system activity.

Immune System. Heating your body several degrees may increase white blood cell activity and destroy microorganisms that are heat sensitive.

Nervous System. Using a sauna inhibits your sympathetic nervous system while strengthening your parasympathetic nervous system. This means a sauna has a strong calming effect on your nervous system.

Detoxification – An important sauna health benefit

You’ve probably read that saunas are good for detoxification.

First of all, heating your body several degrees dramatically increases circulation.

According to Dr. Lawrence Wilson, this helps remove toxins from hard to reach places like bones, sinuses, and teeth.

Many forms of bacteria are heat sensitive, so a sauna’s heat can weaken or kill some of them.

Also, cells damaged by toxic metals and chemicals are weaker than healthy cells. Exposure to some intense heat may be a death sentence for those weaker cells.


Sweating is a great method for removing toxins.

Many substances eliminated through your kidneys can be eliminated through your skin instead. In this way, sweating helps unburden your kidneys.

In case you’re wondering, sweating from exercise is not the same as sweating in a sauna (or steam room).

First of all, saunas conserve your body’s energy by providing an external heat source. This leaves more energy for detoxification.

Second, exercise induced sweating activates your sympathetic nervous system. This reduces the activity of eliminative organs (liver, kidneys, colon).

Parasympathetic Nervous System Enhancement

Stress from any source increases sympathetic nervous system activity.

For the best detoxification results, your body should be as parasympathetic (or relaxed) as possible. Why?

Parasympathetic activity activates your liver, kidneys, and other organs to help eliminate toxins.

Deep Tissue Penetration

Infrared saunas in particular heat tissues from the inside. Some researchers believe this inside-out heating assists with deep tissue detoxification.


I hope this article helped shed more light about the subject of sauna health benefits.

If you have any health conditions, please remember to consult your doctor before using saunas on a regular basis.
