Recurrent cold exposure increases brown adipose tissue
Study demonstrating repeated cold exposure (daily 2-hour sessions at 19°C for 6 weeks) increased BAT activity by 45% and improved cold tolerance in humans.
BAT Adaptation
- BAT activity: +45%
- Cold tolerance: significantly improved
- Shivering threshold: 1.5°C lower
Practical Implications
Regular cold exposure (daily) produces cumulative BAT activation.
Outcomes
