Biohacking
Biohacking spans a wide spectrum — from well-evidenced interventions like cold water immersion and time-restricted eating to fringe self-experimentation. A critical evidence lens separates meaningful optimisation from expensive noise.

Frequently Asked Questions
›Does cold exposure improve health?
Cold water immersion shows evidence for reducing muscle soreness, improving mood (norepinephrine release), and cold adaptation. Evidence for fat loss, immune function, or longevity benefits in humans is currently limited and mixed.
›Is time-restricted eating effective for fat loss?
Time-restricted eating (e.g. 16:8) can help reduce calorie intake by limiting eating windows and may improve insulin sensitivity. However, when total calories are matched, the timing advantage largely disappears — adherence and preference matter more.
›Are wearables worth using for health optimisation?
Continuous glucose monitors, sleep trackers, and HRV monitors provide useful trend data for motivated individuals. Their primary value is behaviour change via feedback loops, not diagnostic accuracy — treat data as directional rather than definitive.
