Sauna - Health Benefits - Exploding Heads

Bathing oneself in heat for the purposes of purification, cleansing, and healing is an ancient practice, dating back thousands of years across many cultures. Variations of its use are seen today in the banyas of Russia, the hararas of Turkey, the sweat lodges of the American Indians, and, most famously, the saunas of Finland. Sauna use, sometimes referred to as “sauna bathing,” is characterized by passive exposure to extreme heat. This exposure elicits mild hyperthermia – an increase in the body’s core temperature – that induces a thermoregulatory response involving hormonal, cardiovascular, and cytoprotective mechanisms that work together to restore homeostasis and condition the body for future stressors. In recent decades, sauna use has emerged as a means to increase lifespan and improve overall health.

I learnt about this finding out of Finland from a study with thousands of participants over 20 years a few weeks ago. I share it here as I think it can help us improve our longevity.

Basically I set up this community to collect research and info about the Health Benefits of Saunas. If you are interested, I would probably start from the bottom (oldest links to newest links)

When you think how quickly the cost of supplements add up over the years - it might make the investment in an in home sauna worthwhile.

Hope you find this interesting.

Or could it be that those that can afford to often take saunas are part of a more privileged milieu and thus have access to better healthcare and are less likely to live in environments with a lot of carcinogens (e.g. not close to an industrial park).

I suspected that at first myself, but in Finland Saunas are very common.

The research showed that there were 3 variables that made a big difference:

  • temperature 177 F degrees
  • time 20 minutes
  • frequency 4 to 7 times a week.

So even if you had a sauna, you would not achieve the same drop in all cause mortality if you were using lower temperatures, less frequency, etc.

Have a read of the research, it is very interesting.

You could update the Wikipedia article on this too, and let me know.


Research into the effects of saunas on people largely comes from Finland. It is generally of low quality and insufficient to make health recommendations. There is some evidence sauna may help reduce blood pressure, but not as effectively as established medication.[36]

There is a strong association between drinking alcohol, taking solitary saunas, and fatality.[36]

A defribrillator and some means of countering dehydration are prudent additions for sauna installations.[36]

There is a suggestion of possible benefit to the heart ventricles for people with heart failure.[37]

Funny, the reference Wikipedia cite [36] actually says:

“More than 2000 sauna bathers were followed for around 20 years in a Finnish population study. The investigators have recently reported health benefits of abundant sauna use for individuals concerning hypertension, ischemic heart disease, dementia and certain pulmonary diseases. Others have recommended the use of sauna for patients with heart failure. Fatal events in sauna are very uncommon and often linked to the use of alcohol, to ischemic heart disease and to bathing alone.”

Fascinating, I did not know that this a phenomenon under study. I will take a look!

I grew up in Mexico, and there are multiple old traditions that emphasize the health and spiritual benefits of sauna-like experiences, a popular example being the Temazcal. It appears that humans have had an intuition for a long time that this type of experience is healthy for the body. I always suspected that this intuition was wrong, and that it was just a psychologically appealing superstition. But I am happy to learn that my suspicions might be unfounded!

Fascinating.

The Japanese also have their Ofuro Hot Tubs. They say this and their diet is why the Japanese live so long.
