The Science & Health Benefits of Deliberate Heat Exposure

About this video

Huberman discusses deliberate heat exposure, including sauna frequency, duration and temperature, and local heating of specific body areas. He explains that heating affects metabolism, cognition and other aspects of health, and describes work published in Cell, as he presents it, in which locally heating skin and fat changed fat cell identity, converting white fat, which he describes as a mostly inactive fuel reserve, toward beige fat, which is rich in mitochondria and more metabolically active. On sauna, Huberman encourages using 80 to 100 degrees Celsius as bookends and five to 20 minutes per session as a rough guide. He cites Susanna Søberg’s study as finding 57 minutes per week of sauna together with 11 minutes per week of deliberate cold as a threshold for metabolic improvements and increased brown fat, divided across sessions. Huberman also links heat exposure to FOXO3 activity and heat shock proteins.

Key takeaways

• Huberman recommends 80 to 100 degrees Celsius and five to 20 minutes as rough sauna guides.
• Huberman cites 57 minutes per week of sauna plus 11 minutes of cold as a metabolic threshold in Søberg’s study.
• Huberman describes local heat converting white fat toward more metabolically active beige fat in research he reviews.
• Huberman links deliberate heat exposure to increased FOXO3 activity.
• Huberman suggests later-day sauna for many people because post-sauna cooling can aid sleep onset.
