UK Bedrooms Can Finally Cool Down in 40C Heat — Just Remove One Thing

British bedrooms can hold heat long after sunset, particularly in well-insulated homes during exceptionally warm nights. One overlooked contributor is the collection of electrical devices quietly releasing heat beside the bed.

Removing electronics—or switching unnecessary devices fully off—can reduce that extra heat load. The effect is modest rather than air-conditioning-level, but it becomes more useful when combined with correct shading, ventilation and lighter bedding.
