Well known health expert Dr. Rhonda Patrick talks about the health benefits of using a sauna, which apparently are many, including the possible reduction of risk of dementia by 66%. See the videos below for what she says and how she does it. The whole list of benefits:
Cardiovascular protection Frequent sauna use is associated with a lower risk of cardiovascular disease, coronary heart disease, stroke, and even sudden cardiac death.
Improved longevity Studies she cites show that people who use saunas 4–7 times per week have significantly lower all‑cause mortality rates.
Heat shock protein activation Heat stress boosts heat shock proteins, which help prevent protein damage, reduce inflammation, and slow muscle atrophy.
Enhanced endurance and VO₂ max Heat exposure mimics moderate‑intensity aerobic exercise and can amplify endurance adaptations from training.
Better muscle recovery Sauna after strength training may reduce muscle soreness and support faster recovery.
Improved insulin sensitivity Regular heat exposure may help regulate blood sugar and improve metabolic health.
Brain health and cognitive benefits Sauna use is linked to lower risk of dementia and Alzheimer’s disease, and heat stress increases BDNF, which supports learning and memory.
Stress reduction and mood improvement Heat exposure increases endorphins and promotes deep relaxation.
Detoxification through sweating Heavy sweating helps eliminate certain environmental toxins and metals (a topic she discusses often).
