Visiting this place three times a week can help prevent dementia?

5 Scientific Reasons Why Saunas Are Good for Your Body

Reduced risk of death from cardiovascular disease

According to a long-term study spanning 14 years, people who use the sauna 2 to 3 times a week have a 25% lower risk of death from cardiovascular disease compared to those who use it once a week. The study took into account physical activity, socioeconomic status, and cardiovascular risk factors. For those who use the sauna 4 to 7 times a week, the risk decreased by up to 77%.

The research team also added that the longer the time spent in the sauna, the better it is for heart health. However, this study only investigated the association between sauna use and heart health and did not establish causality. They also explained that more research is needed regarding this link.

Improve vascular function and reduce the risk of dementia

A study involving middle-aged men in Finland observed that using a sauna 2 to 3 times a week reduces the risk of dementia by 22% and the risk of Alzheimer's disease by 20%. It also suggested that saunas can have positive health effects such as improving vascular function, lowering blood pressure, and reducing inflammation.

Positive effects on respiratory health

According to a study involving approximately 2,000 men in the UK and Finland, participants who used the sauna 2 to 3 times a week or more had a lower likelihood of developing respiratory diseases such as chronic obstructive pulmonary disease (COPD), asthma, and pneumonia. This can be interpreted as sauna use potentially having a positive impact on respiratory health.

Even a gloomy mood can be completely cleared away.

According to a study, there have been reports of depression decreasing after using a sauna. The research team added that the antidepressant effect may stem from 'inflammation reduction' through sauna use. Saunas help reduce inflammation, and increased inflammation is associated with cases of depression.

Helps blood circulation and reduces heart strain

When taking a sauna, blood vessels dilate, improving blood circulation and reducing the burden on the heart. If done regularly and consistently according to one's condition, it can have lasting effects and is sometimes used as a treatment for heart failure. However, sudden temperature changes can strain the heart, so caution is necessary.

Patients with anemia and atopic dermatitis should avoid it.

People with chronic illnesses that cause high energy consumption, such as having a fever or hyperthyroidism, should avoid saunas. Patients with orthostatic hypotension are also at risk because high temperatures cause vasodilation and sweating, leading to dehydration and a sudden drop in blood pressure, which can cause fainting. Those with anemia, early or late pregnancy should also avoid saunas. Additionally, caution is advised for individuals with facial flushing, visible blood vessels due to vasodilation, severe skin dryness, or atopic dermatitis. Furthermore, after alcohol consumption, using a sauna can cause irregular and rapid heartbeat, so caution is necessary.
