Senior Lecturer in Environmental Physiology & Ergonomics @lborouniversity

New paper in PLOS ONE 🔥🛁 20 men did 60-min hot-water immersion (39°C). What they'd actually choose: → Stop at ~31 min, not 60 → Weekly use: ~49 min. Only 15% pick it over walking → Time = the #1 barrier Heat therapy works, but protocols run longer than people will do.

1/ Today the @PhySoc launches its report in Parliament on extreme heat & occupational health. Core argument: air temp limits alone won't protect workers - thresholds need to be physiologically informed. That's the exact gap my own work (under review) digs into.

2/ I reviewed the evidence behind NIOSH's heat work-rest limits (REL/RAL) using strict criteria:only studies with directly measured WBGT + metabolic heat production, not estimates. Of 1,403 records, only 5 studies met the bar. → 0 unacclimated trials conformed to the Alert Limit

3/ → Among acclimated trials, 88% exceeding the Exposure Limit hit core temps >38°C - but so did 33% that stayed within it. → Older adults, women, and multi-day exposure remain understudied. Every trial found sits above the RAL threshold - it's never been tested below it.

🎙️ Joined BBC Radio to talk about heat stress at the 2026 World Cup and why it could be a major challenge for England. The science matters more than “it’ll be warm.” Clip below 👇

People respond to cold exposure very differently ❄️ I spoke with BBC Crowd Science about non-freezing cold injury (NFCI), cold adaptation, and why not everyone reacts the same way - it’s more than mindset.

Understanding these nuances matters for safety, prevention, and performance. Short clip above 🎥 Full episode here: bbc.com/audio/play/w3ct6sts

NFCI can occur without freezing, has long-term consequences, and risks are influenced by physiology, environment, prior exposure, equipment, and context - not race as a simple biological category.

Winter myth-busting time ❄️ 🍷 Alcohol = heat? Briefly. Then you get colder. 🧦 Extra socks? Only if your feet can breathe. 🧥 Too many layers too fast = sweat = cold. Read more in my latest piece for @Telegraph. Link in comments
