Saunas are a hot trend and they can even help your health.
Less than a month into the winter, the cold temperature crushed my spirit. Every time I leave home, an unexpected school day falls in the snow, a frozen dogshit bound sidewalk: I’m done. I found myself dreaming not only of spring, but of any kind of warmth. Sauna sounds very good now. In addition to cold breathing, regular meetings have many health benefits.
In fact, studies have shown that some positive health outcomes are linked to regular sauna use. A 2015 study of more than 2,300 middle-aged men in Finland more frequently found a person’s risk of sauna, fatal heart disease and premature death. The same group of researchers also reported a link between regular sauna use and high blood pressure, as well as a lower risk of moderate to severe sauna use and dementia.
One caveat: with the exception of all men, Finnish saunas are so entrenched that it’s hard to find anyone who doesn’t use them. So no control group USES them all – only those who use them use them more or less.
For this type of study, it is not possible to know whether it is a sauna or a related factor, such as being able to withstand frequent R&R, which brings benefits. With rita Redberg, heart disease, the university of California, San Francisco medical center writing medical editor in JAMA study in 2015, “we don’t know why, who more frequently to take sauna, people’s life expectancy longer (whether in a hot room, leisure time, let more leisure time or sauna leisure life friendship).
The study’s author, Tanjaniina Laukkanen, a researcher at the university of eastern Finland, told Shots in an email that the team believes calories and relaxation are important factors. Heart rate increases with body heat exposure. 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 body can have many beneficial mechanisms,” he said. He is doing heat therapy for people who can’t get enough exercise, such as spinal cord injuries.
The comparison doesn’t 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 body is in good condition, often play a sauna the cardiovascular prognosis of men are superior to those who only suitable for this kind of men.
So, should we take a proper sauna? “Saunas obviously take time,” Mr. Redberg said in a 2015 editorial. She wrote in a recent post details, 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, are likely to reduce musculoskeletal pain and headache. She recommends that patients, including massage, yoga and pilates, take a sauna as part of relaxation and stress relief activities. She also recommends physical activity, especially walking.
Of course, there are some caveats. People who are sleepy or have low blood pressure may need to be careful, or at least drink a lot of water before and after drinking, which is good advice for all saunas. If your heart attack is unstable, you should be careful and consult your doctor first.
According to the 2009 infrared saunas and review evidence of cardiovascular health, traditional sauna will air heated to about 185 degrees, which in turn heat you, infrared sauna (also called the far infrared sauna room) can reach 140 degrees. But infrared rays penetrate deeper into the body, meaning you can sweat at lower temperatures than in a traditional sauna. This creates a lighter demand for the cardiovascular system, which is similar to moderate walking, and therefore may benefit people who are sedentary for health reasons. For those who love a sauna, this is a good thing, but it’s not pleasant.
A review of nine studies found “limited and moderate evidence” that using infrared saunas improved blood pressure and congestive heart failure, as well as limited evidence of improvement in chronic pain. Infrared saunas are also part of the waon treatment used in Japan, including 15 minutes of heat, 30 minutes of reclining and towel wrapping. (please register!) There is evidence that waon treatment can benefit patients with heart failure.
Laukkanen says her team’s work cannot be applied directly to infrared saunas, and more research is needed to reduce their long-term benefits. No matter where you’re drawn, don’t assume you sweat a lot because of your health (frequent sales claims). Elimination of toxins is primarily the work of the kidneys and liver, not your sweat.
