37C Heatwave Warning: One ‘Cooling’ Mistake Could Make You Hotter

An ice-cold shower appears to offer instant relief during extreme heat, but the body’s response can make it less effective than expected. Sudden cold constricts blood vessels near the skin, potentially reducing the release of internal heat after the initial chill fades.

The warning emerged as the Met Office forecast highs of 37°C in southern England and an eventual peak of 38°C, accompanied by unusually high humidity and very warm nights. Official advice recommends cool water—not the coldest temperature available.
