The Connection Between Sauna Use and Cognitive Health

Traditionally, saunas have been used as a means of relaxation and detoxification.

Originating from Finland, the sauna has a rich history that spans thousands of years.

Saunas were initially used by the Finnish people for a variety of reasons, from promoting relaxation and wellbeing, to preparing food, and even for childbirth.

Over the years, the use of saunas has evolved and spread across the globe, with many cultures adopting it for its purported health benefits.

Benefits of Sauna Use

Regular sauna use has been linked with numerous health benefits, including improved cardiovascular health, better skin health, enhanced immune function, and even weight loss. It’s also been known to reduce stress and improve overall wellbeing. But could there be a connection between sauna use and cognitive health?

The Connection Between Sauna Use and Cognitive Health

The Human Cognitive System

Cognitive health refers to the health of the brain and its various functions, which include learning, memory, perception, and problem-solving.

What is Cognitive Health?

In essence, cognitive health is about how well your brain can perform these complex functions. It’s the state of your brain’s health that enables you to engage with and navigate the world around you.

Importance of Cognitive Health

Maintaining cognitive health is crucial for our overall quality of life. It allows us to perform everyday tasks, learn new skills, recall memories, and much more. However, cognitive health can decline over time due to factors like aging, stress, and lifestyle choices.

Understanding the Connection: Sauna and Cognitive Health

An increasing body of research suggests a potential link between regular sauna use and improved cognitive health. The benefits might be due to various factors, from heat shock proteins to improved blood flow.

Scientific Studies and Research

Study 1: Frequent Sauna Use and Dementia

A 2017 study in Finland observed that men who used a sauna 4-7 times a week had a significantly lower risk of developing dementia and Alzheimer’s disease compared to those who used the sauna once a week.

Study 2: Sauna Use and Neurocognitive Diseases

Another study published in the Journal of Alzheimer’s Disease reported similar findings. It indicated that regular sauna use might lower the risk of memory diseases, further hinting at the potential cognitive benefits of sauna use.

The Role of Heat Shock Proteins

Heat shock proteins (HSPs), produced in our bodies in response to stressors like heat and exercise, might play a role in this connection.

Heat shock proteins (HSPs) may assist in maintaining brain health by preventing protein aggregation – a process associated with several neurodegenerative diseases. Regular sauna use, which exposes the body to high temperatures, could help stimulate the production of these protective proteins.

Sauna Use as a Preventive Measure

While more research is needed, these findings suggest that regular sauna use might be a valuable tool for maintaining cognitive health and preventing neurodegenerative diseases.

Frequency and Duration

According to the studies, a frequency of 4-7 sauna sessions per week may be beneficial. However, it’s also important to consider the duration and temperature of each session. Most studies have considered sessions of around 15-20 minutes at temperatures of 80-100°C.

Combining Sauna Use with Other Healthy Habits

As with any aspect of health, a holistic approach is best. Regular exercise, a healthy diet, good sleep, and mental stimulation are all essential for cognitive health. Sauna use could be an excellent addition to a healthy lifestyle routine.

Precautions and Considerations for Sauna Use

While saunas are generally safe for most people, there are certain considerations to keep in mind. Those with cardiovascular conditions, pregnant women, and individuals who are ill should consult with their healthcare provider before using a sauna. Always ensure to stay hydrated and listen to your body, exiting the sauna if you start to feel unwell.


The connection between sauna use and cognitive health is an exciting area of research, with studies suggesting that regular sauna use could potentially boost cognitive function and decrease the risk of neurodegenerative diseases. However, it’s important to keep in mind that sauna use is just one piece of the puzzle. A balanced lifestyle, complete with a healthy diet, regular exercise, and good sleep, is crucial for maintaining optimal cognitive health.


  1. Can sauna use improve cognitive health? Current research suggests that regular sauna use might potentially boost cognitive health and decrease the risk of neurocognitive diseases. However, more research is needed.

  2. How often should I use the sauna for cognitive benefits? While there’s no definitive answer, some studies suggest a frequency of 4-7 sauna sessions per week.

  3. Can sauna use replace exercise for cognitive health? Sauna use should not replace regular exercise. It can be an excellent addition to a healthy lifestyle routine.

  4. Are there any risks associated with sauna use? While generally safe, individuals with certain health conditions should consult their healthcare provider before using a sauna.

  5. What are other ways to boost cognitive health? Healthy habits such as regular exercise, a nutritious diet, good sleep, and mental stimulation are all crucial for cognitive health.
