European clock changes spark health and policy debates
The biannual adjustment of clocks in Europe continues to prompt discussions regarding public health and regulatory policy. In October 2026, clocks are set back one hour to transition from summer to winter time. While this provides an extra hour of sleep, research indicates that the transition can disrupt biological rhythms.
A 2026 international literature review of 157 studies across 36 countries found that the transition to summer time is linked to a temporary increase in heart attacks and fatal traffic accidents. Conversely, the shift to winter time may lead to increased sleep and fewer workplace accidents. The Dutch National Institute for Public Health and the Environment (RIVM) suggests that maintaining permanent standard time (winter time) may be more beneficial for public health as it aligns better with natural daylight cycles.
Health insurance provider DAK-Gesundheit reported that 30 percent of people surveyed in February 2026 experienced symptoms following a time change, including fatigue, sleep disorders, concentration issues, and irritability. While the European Commission previously proposed abolishing biannual changes in 2018 to allow member states to choose a permanent setting, the debate over the optimal time standard remains ongoing.
