UK Heat Spike Exacerbates Depression and Sleep Problems

Rising temperatures are linked to worsening mental‑health symptoms. Heat can aggravate depression by disrupting sleep, increasing irritability and triggering anxiety, and people taking certain antidepressants may become more heat‑sensitive. Seasonal affective disorder can also appear in summer, with symptoms such as insomnia, poor appetite and agitation. Experts advise maintaining a regular sleep schedule, staying hydrated, using blackout curtains and consulting healthcare providers about medication effects.

In the United Kingdom, the likelihood of days exceeding 40 °C has risen more than twenty‑fold since the 1960s, and humidity further hampers the body’s cooling through sweat. Practical steps to improve sleep in hot weather include keeping sunlight out of bedrooms, using cross‑ventilation when outdoor air is cooler, shading sun‑facing rooms, and employing passive cooling measures such as blinds, awnings or reflective roof materials.
