Every year, on the last Sunday in March, the time is set forward by one hour at 2 a.m. It instantly becomes 3 a.m. Since most people are still asleep at that time, they do not notice directly. The alarm clock rings as usual at 6:23 a.m., but in reality, it is only 5:23 a.m. The internal clocks have not been adjusted and have not yet adapted to the fact that things are starting earlier now. Waking up is exhausting. There is still too much melatonin and too little cortisol in the blood. The average person needs about two to three weeks to adjust to daylight saving time. The effects are similar to jet lag. Hospitals report a high increase in patients up to three weeks after the daylight saving time change. Interestingly, the accident rate increases by 30% after the switch to daylight saving time. The ACE and ADAC report similar correlations with this time shift. Some people are thrown off their rhythm to the extent that they can't sleep as usual for one to two weeks. Our chronobiological system seems to be quite sensitive in this regard. What can be done to make the transition more bearable? There is a simple trick: "chunking" the time change. Start setting your alarm clock ten minutes earlier each day six days before the time change, so that you don't have to adjust on the day of the time change. This gently staggered adjustment of wake-up times is much easier for the body to cope with than the usual abrupt change. With this trick, your physical processes are optimally adjusted on the day of the time change, and you will feel fit. Of course, after the time change, make sure to consistently go to bed at the usual time and don't listen to the inner voice telling you, "I know it's only an hour earlier."
