Overview

• The UK and other countries observing daylight saving time moved clocks forward, marking the start of British Summer Time on March 30, 2025.
• Health professionals warn that the time change disrupts circadian rhythms, increasing risks of heart attacks, strokes, and other health complications, particularly in vulnerable populations.
• Studies show a 24% spike in heart attacks on the Monday following the spring clock change, with strokes also increasing by 8% in the subsequent days.
• Experts recommend gradual sleep adjustments, exposure to morning light, and stress management to mitigate the negative effects of the time shift.
• Despite widespread dissatisfaction with biannual clock changes, legislative efforts to adopt permanent standard or daylight saving time have stalled, leaving the debate unresolved.
