According to a Finnish study, regular sauna visits can have the same health benefits as cardio -- including lower blood pressure, lower risk of heart disease, better joint health, and an increase in longevity. All you have to do is spend 20 minutes per week in a sauna that's heated between 175 and 210 degrees F.
And if you can spend more time in the sauna -- that's even better. People who relaxed in a sauna four to seven times a week had 60 percent lower rates of heart disease and stroke than those who sat in a steam room just once a week.
Researchers theorize that the increased heart rate brought on by the heat results in an increase in blood flow throughout the body, which creates benefits similar to doing cardio. But don't throw out your running shoes just yet.
Lead researcher Dr. Jari Laukkanen says saunas aren’t a replacement for workouts -- but something that should be used to supplement them. “The combination of good fitness and regular sauna use is related to a lowered risk of diseases,” he says. “Sauna is good after [the] gym or aerobic exercise … I do it normally, almost every evening!” Read more here: https://nypost.com/2018/09/10/sitting-in-a-sauna-might-be-just-as-productive-as-cardio/
