Saunas are a hot trend and they may even help your health.

Less than a month into winter, the cold temperatures have crushed my spirit. Every time I leave the house, an unexpected school snow day, a sidewalk of frozen dog poop class bundling: I’m done. I find myself dreaming not only of spring but of any form of warmth. So the sauna sounds very good now. In addition to the respite from the cold, there are many health benefits from regular meetings.

In fact, studies show that some positive health outcomes are associated with regular sauna use. A 2015 study of more than 2,300 middle-aged men found in Finland more frequently a person took a sauna, a fatal heart disease and a risk of premature death. The same group of researchers also reported on the relationship between routine use of saunas and high blood pressure, as well as a lower risk of moderate to severe saunas and dementia.

A warning, except that all men are male, the sauna in Finland is so entrenched that it is hard to find anyone who doesn’t use it. So no control group USES them completely – only those who use them use them more or less.

For this type of study, it is impossible to know whether it is the sauna itself or some related factors, such as the ability to bear the frequent R&R, which brings benefits. With rita Redberg, heart disease, the university of California, San Francisco medical center in JAMA written medical editor’s note with a 2015 study, “we don’t know why, who take sauna more frequently people have a longer life expectancy (whether in a hot room, take the leisure time, to allow more leisure time or sauna leisure life friendship).

The authors of the study, Tanjaniina Laukkanen, a researcher at the university of eastern Finland, told Shots in an email that the team believed that heat and relaxation were important factors. As the body heat is exposed, the heart rate increases. This will help improve cardiac output.

Saunas also seem to improve the function of blood vessels. Christopher Minson, a professor of human physiology at the university of Oregon, studied the effects of heat immersion in hot water. ‘just like exercise, heat is a global stressor, and the whole body can have many beneficial mechanisms,’ he says. He is working on heat therapy for people who are unable to exercise adequately (such as spinal cord injuries).

The comparison of this exercise does not mean that if you can do this, you should skip the exercise. Laukkanen team another study showed that the cardiovascular exercise and sauna use independent role to a certain extent, the physical condition is good, often play the cardiovascular prognosis of sauna men better than those only suitable for these types of men.

So, should we all take a proper sauna? “Saunas are clearly taking time,” Redberg said in the 2015 editor’s note. She Shots in the recent detail said in an E-mail, the study and subsequent research has shown that the use of the sauna is associated with some positive health outcomes, such as lowering blood pressure, may reduce musculoskeletal pain and headache. She recommends to patients, including massage, yoga and pilates, and saunas are one of the activities to relax and relieve stress. She also recommends physical activity, especially walking.

Of course, there are caveats. People who pass out or have low blood pressure may have to be careful, or at least drink a lot of water before and after drinking, which is good advice for all saunas. If you have an unstable heart attack, you should be cautious and consult your doctor first.

According to a 2009 review evidence of infrared saunas and cardiovascular health, traditional sauna will ambient air heated to about 185 degrees, which in turn heat you, infrared sauna (also known as far infrared sauna room) can reach 140 degrees or so. But the infrared penetrates deeper into the body, which means you start to sweat at a lower temperature than the traditional sauna. This creates a lighter need for the cardiovascular system, which is similar to moderate walking, and may therefore benefit those who are sedentary for health reasons. For those who like the sauna, it’s a good thing, but it’s not pleasant.

A review of nine studies found that the use of infrared sauna can improve the “limited and moderate evidence” of blood pressure and congestive heart failure symptoms, as well as limited evidence of chronic pain improvement. Infrared saunas are also part of the waon therapy used in Japan, which includes 15 minutes of heat, then 30 minutes of reclining and wrapping in a towel. (please register!) Evidence suggests that waon therapy can benefit patients with heart failure.

Laukkanen said her team’s work could not be applied directly to the infrared sauna, requiring more research to reduce their long-term benefits. Whatever it is you’re attracted to, just don’t think you’re sweating it out for your health (frequent sales claims). The removal of toxins is mainly the work of the kidneys and liver, not your sweat.
