Standard time - no problem

It’s the time of year again: We switch to standard time. Every year on the last Sunday in October we adjust the time from 3 to 2 a.m. That sounds awesome at first glance, for then we can sleep in for another hour. But does our body really find that awesome? How often does one hear the complaints weeks in advance, that with the onset of standard time it gets dark so early again? That primarily annoys us because most of us leave the house in the morning when it’s still dark and come back home when it’s dark again in the evening. One feels almost cheated of the day, as one gets supposedly less out of it when there is a lack of solar light. During daytime, when it’s gray and rainy outside – just fall – we are often distempered, tired and exhausted. When sunlight is rare, it’s hard for us to refill our energy supply.

And yet standard time is the actual normal time, also known as Central European Time (CET). It’s the daylight savings that has been constructed artificially. It has been implemented to cause significant savings of energy by using the daylight more efficiently and thus reducing the power- and heating costs.

And really: With the switch to standard time by the end of October, our body actually has a reason to cheer. Although the change into this direction may slightly jumble our biorhythm in the beginning, those few grievances that are reported are generally minor grievances and affect only a relatively small number of people. Inherently, the change to standard time suits us fine. Even though some have to fight problems as sleep disorders or enhanced fatigue, the 25-hours-rhythm that occurs on the day of time change, matches the diurnal rhythm that is rooted inside of us. Scientists discovered that people who live isolated and without a natural source of light for a while, develop a 25-hours-diurnal rhythm. Apparently, this matches our biological clock. Inter alia, this is proven by a study realized by the Max-Planck-Institute for Behavioral Physiology dated in the 1960s.

The annual change to daylight saving time potentially brings by far more problems for the organism than the switch to standard time. There a phenomenon called mini-jetlag is talked about, which often impacts the body for days or even weeks. So forget „Bonjour tristesse.“ Let’s welcome winter with open arms and enjoy the next month – just normal time(s).
