Short n' Sweet

We all know a relaxing session in the sauna helps ease the mind and muscles, open the airway and warm the soul; but did you know there is scientific evidence that supports the connection between regular sauna use and a healthier heart and longer life? If you haven't been taking advantage of the sauna, now is the time!

Further Understanding

Using the sauna to relax has several benefits like reducing stress and physical tension in the body. Additionally, studies are emerging that show the correlation between frequency of sauna use and better health. 
A recent study confirmed that, "Emerging evidence suggests sauna bathing has several health benefits, including a reduction in the risk of vascular diseases such as high blood pressure, cardiovascular disease, stroke and neurocognitive diseases. It also shows benefits for nonvascular conditions like the common flu, as well as certain skin conditions and even pain from rheumatic diseases and headaches."
It's important to remember that using a sauna won't replace a hard workout, but it has its own benefits; there is evidence to suggest that using a sauna in addition to working out is more beneficial than working out alone. 

The Verdict

To put it simply, using a sauna will not replace a HIIT workout or marathon, but it will enhance your current routine. No one wants to waste time, and using a sauna is definitely not a waste of time. If you are interested in less cardiovascular risk, stress and tension.
