degrees Fahrenheit is the upper limit for sauna temperature to avoid increased risks

Sauna Benefits

Frequent sauna use is associated with lower dementia and Alzheimer's risk.
Sauna use mimics moderate intensity exercise, improving cardiovascular health.

Heat Shock Proteins

Heat shock proteins help repair misfolded proteins and prevent aggregation.
Sauna use activates heat shock proteins significantly.

Temperature Considerations

Saunas above 190°F may pose increased risks.
Optimal sauna temperature for benefits is around 174°F to 190°F.

Hot Tubs vs. Saunas

Hot tubs offer comparable cardiovascular benefits.
Bathing at 104°F for 20 minutes can yield similar effects to sauna use.
