Daylight Saving Time: Why the switch to summer time affects our health

Published 2026-10-23

The next time change is approaching in Germany. On Sunday night, clocks will once again be set forward to summer time. While many people enjoy the longer evenings, experts regularly warn about the health consequences of this shift.

Studies show that the switch to summer time poses a challenge for many people. The sudden loss of an hour of sleep disrupts the body's internal rhythm. This process is often referred to as a "mini-jetlag," as the body must first adjust to the new daily schedule.

Medical professionals view the effects on the cardiovascular system as particularly critical. Statistically, the risk of heart attacks increases slightly in the days immediately following the change. Mental health issues or difficulties with concentration also occur more frequently during this time, as the body is under stress.

To mitigate the negative effects, sleep experts recommend slowly adjusting one's sleep rhythm a few days before the change. Avoiding caffeinated drinks in the evening and getting plenty of natural daylight in the morning can also help bring the internal clock back into sync with the new time more quickly.

Although the discussion regarding the abolition of the time change has been ongoing in the European Union for years, there is no final decision yet. Until then, the changing of the clocks remains a fixed part of daily life in Germany, to which the population must adapt anew every year.
