• The foundational human study on cold-activated brown fat. Found BAT activity in 96% of subjects during cold exposure, with significant links to metabolic rate and body composition. 

2. Frontiers in Physiology—Effect of Acute Cold Exposure on Energy Metabolism and BAT Activity (Meta-Analysis)

• A systematic review and meta-analysis of human studies examining how cold exposure affects brown fat activity and energy expenditure.

3. MDPI Biomedicines—Metabolic Effects of Brown Adipose Tissue Activity Due to Cold Exposure (2024)

• A 2024 systematic review and meta-analysis of RCTs specifically assessing how cold-induced BAT activation affects glucose and lipid metabolism in healthy humans.

4. Frontiers—Weighing in on the Role of Brown Adipose Tissue for Treatment of Obesity (2024)

• Published by the University of Toronto, this 2024 paper covers BAT as an emerging target for obesity treatment and the role of thermogenesis in weight management.

5. PLOS ONE—Effects of Cold Water Immersion on Health and Wellbeing: Systematic Review and Meta-Analysis (2025)

• The most comprehensive recent meta-analysis on CWI specifically, covering 11 studies and 3,177 participants across multiple countries.
