Study on regular sauna use and how it affects health

Good health with the help of a sauna?

Saunas have long been hailed as a therapeutic practice, and new research suggests its benefits extend far beyond relaxation. In his new book, Hans Hägglund, an assistant professor at the Medical Institute, explores the many health benefits of regular sauna use.

Contrary to common misconceptions, saunas do not pose a risk to people with cardiovascular conditions. On the contrary, Hägglund points out that studies indicate half the he risk of cardiovascular disease after regular sauna visits. In addition, the risk of stroke and dementia is reduced by over 50% through frequent sauna sessions.

Sauna doesn't just offer a break for the body; it also stimulates the body's immunological functions and the nervous system. Blood vessels dilate, blood pressure drops and blood lipids decrease, which contributes to potential cardiovascular benefits.

Sauna often to maximize benefits

The benefits extend beyond the cardiovascular system. Sauna bathing is said to be linked to improved sleep quality and reduced anxiety. It should also have an antidepressant effect as well as relief from headaches and aches in general . Hägglund points out that the frequency of sauna visits matters. Two to three saunas a week show some effects and a more noticeable effect is shown at four to seven sessions per week.

Hägglund himself is an advocate of daily sauna sessions, inspired by his long-term involvement in the Swedish Sauna Academy and his passion for exploring the health effects of the sauna. He envisions a future where saunas are prescribed as often as physical exercise.

However, saunais not a universal solution. Certain conditions, such as fever, ongoing infections, acute myocardial infarction or unstable angina, require caution. Those who cannot sweat, people with multiple sclerosis and women with postmastectomy lymphedema should also use saunas with caution. Hägglund advises against alcohol consumption or sauna baths when you are hungover due to the increased risk of negative reactions such as dehydration.

More research is required and is underway

Hägglund's book aims to inform a wide audience, from those who are curious about the health benefits of the sauna to healthcare professionals. While providing insights, the book also raises questions, reflecting the complexity of this field. As his research continues, Hägglund has contributed to the establishment of a sauna laboratory at Sunderby Hospital in Luleå. The journey to understand the sauna's full potential is ongoing. Research into its effects on heart function, strengthening the immune system and conditions such as rheumatism continues to reveal the many dimensions of this ancient practice.
