Within the corpus, key tensions emerge regarding the consistency and translatability of BAT findings. The effect of habitual cold exposure in Arctic adults, as reviewed by Jensen 2025, presents a nuanced picture where some studies report stable supraclavicular skin temperature post-cooling (P < 0.001 for sternum decline), while others show variable BAT activation. The long-term health implications remain speculative; for example, BAT is proposed to mediate healthful longevity based on mouse transplantation studies, but human cohort data directly linking BAT activity to longevity endpoints are sparse (Zhang 2024). This underscores the gap between established mechanistic plausibility and definitive human clinical evidence.
