saunas and dementia: a hot topic in health research

The buzz about saunas is heating up, and it's not just due to trending wellness influencers or the latest health podcasts. A growing body of scientific research suggests a potential link between regular sauna sessions and numerous health benefits, including the prevention of dementia. Beyond the therapeutic warmth and relaxation, there’s an entire world of community and ritual that saunas offer.

Finland, where saunas are deeply ingrained in the cultural fabric, has been the epicenter of this research. A popular Finnish saying suggests that a sauna is akin to a universal pharmacy. Recent studies have lent weight to this ancient wisdom.

Jussi Kauhanen, M.D., Ph.D., from the University of Eastern Finland, recently highlighted an intriguing discovery. Examining data from the 1980s on middle-aged Finnish men, researchers found that those who indulged in sauna sessions 4-7 times weekly had an impressive 65% reduced risk of Alzheimer's or dementia over the next two decades, in comparison to those who visited just once a week. Another study in 2020 echoed these findings, showing that frequent sauna-goers exhibited a notably decreased dementia risk.

But why might saunas have this effect?

The Brain Boost from Saunas

On the surface, sweating away in a sauna might appear passive. Yet, our bodies undergo significant processes during this time. Dr. Kauhanen likens it to the benefits of physical exercise. Both activities reduce inflammation, a suspected player in dementia. Furthermore, saunas and exercise stimulate the production of proteins vital for brain health and resilience.

Notably, saunas might benefit our cardiovascular system. Dr. Christopher Chen from the National University Health System in Singapore argues that like exercise, saunas may enhance arterial function, stabilize blood pressure, and facilitate efficient nutrient transport, thereby promoting brain health.

Moreover, saunas can be a communal event. Given that depression and feelings of isolation are known dementia risk factors, the social aspect of sauna sessions – particularly in Finland – might play a role in its protective effects. Though, this social element may vary across cultures.

However, Jason Karlawish, M.D., of the University of Pennsylvania, emphasizes that while saunas have their merits, they aren’t a standalone solution for dementia. Their benefits could be one of the many factors in promoting overall brain health.

Sauna Sessions: A Guide

If you’re considering integrating saunas into your wellness routine, here’s a tip: balance is key. Enjoy sessions ranging from 5 to 20 minutes, perhaps coupled with cold exposure for rejuvenation. Always begin with shorter durations, and heed your body’s signals.

In essence, if saunas resonate with you and complement your holistic health practices, they might just be a warm addition to your wellness journey.
