Conclusions and Relevance  Increased frequency of sauna bathing is associated with a reduced risk of SCD, CHD, CVD, and all-cause mortality. Further studies are warranted to establish the potential mechanism that links sauna bathing and cardiovascular health.

Have your doctor reconcile sauna use with this research;

Mortality rates increase due to extreme heat and cold

Up to now it has been known that high temperatures, amongst other things, can affect the blood-clotting mechanism (haemostasis) and make the blood more viscous, thereby increasing the risk of thrombosis. Furthermore, as decreasing temperatures have an impact on blood pressure, it can be assumed that there is a link between cold temperatures and the increase in cardiovascular events and stroke.
