Optimal Duration and Frequency of Heat Stress for Health Benefits
For health benefits from heat stress, staying in a heat session for no more than 30 minutes is ideal as it plateaus after this duration. Overdoing it can lead to negative impacts like increased cardiovascular diseases and faster cell aging. The recommended time window for benefits is between 10 to 20 minutes per session. Dividing 57 minutes per week across 2-3 days, alternating between sauna and cold plunges, with no more than two saunas per day, results in 10 to 14 minutes per session. It is suggested not to exceed 30 minutes in a single session to avoid negative effects. Additionally, for multiple rounds in one day, staying within the 10 to 15 minutes per session range is feasible and adequate for health benefits.
