Dr. Jari Laukkanen, a leading sauna researcher and cardiologist, discusses his research on the health benefits of sauna use with the host. The conversation centers on studies showing that regular sauna use is associated with reduced cardiovascular-related mortality, all-cause mortality, and risk of dementia and Alzheimer's disease. Key findings include a dose-response relationship, where more frequent and longer sauna sessions yield greater risk reduction, specifically at least four times a week for at least 20 minutes at 79 degrees Celsius. Dr. Laukkanen also explores potential mechanisms, such as blood pressure reduction, improved vessel function, and the activation of heat shock proteins, and touches on the Finnish tradition of combining sauna with cold exposure.
