From Longevity Magazine:

“I have been using saunas for as long as I can remember – whether it is at the gym, in a spa, in a hotel while traveling or even during a hot yoga class. Saunas are not a new phenomenon, and their use has been well documented over time across many cultures, including the Romans, the Turks, the British and, most importantly, the Finnish – who have perfected the art and science of the sauna.

In fact, scientists from the University of Eastern Finland have been studying this national activity for some time, and recently published a new paper to support previous studies showing sauna bathing is associated with a variety of health benefits. The researchers say taking a sauna for 30 minutes can help to improve the ability of your blood vessel wall to expand and contract passively with changes in pressure – which is an important function of large arteries and veins. The high temperatures of a sauna may also provide some cardiovascular conditioning, as they can drive heart rates to levels often achieved by moderate-intensity physical exercise.”  read the full article here.
