Possible health benefits of Sauna

Regardless of how a sauna is heated, or the humidity level, the effects on the body are similar.

When a person sits in a sauna, their heart rate increases and blood vessels widen. This increases circulation, in a similar way to low to moderate exercise depending on the duration of sauna use.

Heart rate may increase to 100-150 beats a minute while using a sauna. This may bring some health benefits.

Easing pain

Increased circulation may help reduce muscle soreness, improve joint movement, and ease arthritis pain.

Reducing stress levels

As the heat in a sauna improves circulation, it may also promote relaxation. This can improve feelings of well-being.

Improving cardiovascular health

The reduction in stress levels when using a sauna may be linked to a lower risk of cardiovascular events.

One study, conducted in Finland, followed 2,315 men ages 42 to 60 over the course of 20 years. Findings suggested that people who use a sauna may have a lower risk of dying from cardiovascular disease.

Of the participants in the study, a total of 878 died from cardiovascular disease, coronary artery disease or sudden cardiac death. Participants were categorised by how often they used a sauna, including once a week, two to three times a week, and four to seven times a week.

After adjusting for cardiovascular risk factors, increased sauna use was linked with a reduced risk of fatal cardiovascular-related diseases.

Participants who used the sauna two to three times a week were 22 percent less likely to experience sudden cardiac death than those who only used it once a week. Those who used a sauna four to seven times a week were 63 percent less likely to experience sudden cardiac death and 50 percent less likely to die from cardiovascular disease than those who only used a sauna once a week.

More research is needed to find out if there is a definite link between sauna use and a decrease in deaths from heart disease.

Sauna use may also be associated with lower blood pressure and enhanced heart function.

While studies may be promising, sauna use should not replace an exercise program to keep the heart healthy. There is more evidence to support the benefits of regular exercise.
