Dr. Jari Laukkanen on Sauna Use for the Prevention of Cardiovascular & Alzheimer’s Disease

Summary

The podcast episode titled Dr. Jari Laukkanen on Sauna Use for the Prevention of Cardiovascular & Alzheimer’s Disease discusses the benefits of sauna sessions for improved cardiovascular health, longevity, and dementia prevention. Dr. Laukkanen's research has shown that frequent sauna use, at temperatures around 79 degrees Celsius, can reduce the risk of cardiovascular mortality by up to 50% for men who use saunas four to seven times a week. For those who use saunas two to three times a week, there is a 27% reduction in cardiovascular mortality. Sauna use also resulted in lower blood pressure levels, improved endothelial cell activity, and arterial compliance.

The podcast also touched upon the activation of heat shock proteins by sauna use and the acute changes in vessel function. One of the interesting discussions centered around the timing of sauna use in relation to exercise. Although there is some speculation on the optimal time required for effective sauna use, the speakers highlighted the good evidence supporting exercise benefits, like prior exercise improving adaptation to heat stress, which suggests that a post-exercise sauna could work well to assist in recovery.

The study also showed a dose-response effect on Alzheimer's disease and dementia. Dr. Laukkanen also cautions those with pre-existing heart conditions, emphasizing on the need to consult with a physician before starting a sauna program.

Concluding, the call for increased research was highlighted to determine optimal sauna use, benefits of sauna use in combination with exercise which could lead to practical solutions in the prevention of several diseases.
