This weekend it’s that time again: The clocks will be changed back one hour, from daylight saving time to standard time.
Since the beginning of the Corona Data Donation, this is the third clock change. Whether these changeovers are useful, unnecessary or even harmful is widely debated - both in terms of personal preference and public health. After all, numerous studies have shown that in the short term, the changeover can disturb one’s routines and well-being. In the long term, the changes influence when and how much sunlight we get in our daily lives. This can have a variety of effects on our bodies and psyche, in part mediated by changes in our sleep.
