Changing the time by just one hour doesn't seem too drastic at first glance, but changing winter and summer time can bring many inconveniences. The biological clock, which is mainly guided by daylight and darkness, can hardly tolerate such sudden changes. For many, this means a stressful start, as they need days to adjust to the new rhythm. Why can changing the clock be a shock to the body and how does it affect our health?
Changing the clock may only mean an extra hour of sleep in the fall or a longer day in the spring, but the body experiences it completely differently. Our biological clocks work in a strict rhythm regulated by daylight, and sudden changes in the body trigger real chaos. From sleep disturbances and an increase in heart problems to concentration problems and seasonal depression, the impact of changing the clock on health and well-being has been proven to be multifaceted. Many experts warn that this practice brings more harm than good, and at the same time, the EU has been negotiating for several years to stop moving the clock, but without success. So why can a clock shift be such a big shock to the body and how can its negative effects be mitigated?
Disturbance of biorhythm and circadian rhythm
The human body naturally follows a circadian rhythm that is synchronized with daylight, so any change, such as changing the clock, is unpleasant for it. According to research, people often have trouble sleeping due to clock shifts, as the internal biological clock takes a few days to adjust to the new schedule. Sleep disorders can lead to chronic fatigue, poorer concentration and even an increased risk of accidents in traffic or at work.
Greater heart and mental health risks
Research shows that changing the clock has a negative effect on the cardiovascular system. Some studies have shown an increase in heart attacks by about 25 % in the first days after the change to daylight saving time. At the same time, the risk of depression increases, especially in autumn, when the days are shorter and there is a lack of light. It is this lack of light that is associated with so-called seasonal affective disorder, which people experience in the form of mood swings, low energy and increased cravings for junk food.
More accidents and less productivity
In particular, the change of clocks in the spring, which deprives us of an hour of sleep, is associated with an increase in errors and accidents, both in the workplace and in everyday life. According to the research, the number of traffic accidents is significantly higher after the spring time change, and there are also more mistakes in the work environment, which is attributed to fatigue and poor concentration of employees.
Worse eating habits and impact on body weight
According to some research, people reach for unhealthy snacks more often after the clock has changed, which is especially pronounced on days with bad weather or less light. The spring shift thus not only affects sleep, but also weakens self-control when eating, which leads to higher calorie intake and can lead to weight gain in the long run.
EU clock ticking: will we ever stop?
For years, the European Union has been debating whether to end the clock shift, as sleep experts believe that permanent winter time would be more in line with human biological rhythms and have positive effects on health. While some countries tend towards winter time, others want to keep summer time, mainly because of tourism and the evening light, which has a positive effect on the mood.
How to spend the shift of the clock more easily?
While eliminating clock drift is not yet a reality, a few simple measures can help mitigate the effects of the change. It is recommended to gradually adjust the time of going to bed a few days before the change of clock. It is also beneficial to spend as much time as possible in daylight and avoid electronic devices before bed. In this way, we can help the body to adjust to the new clock as soon as possible.
Conclusion
The movement of the clock still brings more questions than answers, and above all, it has a negative effect on the health and well-being of many people. Given the health effects that experts are increasingly studying, the question is whether permanent time would be a better solution for everyone. Until then, make sure you get through the clock shift as easily as possible by adjusting your daily routine and taking extra care of your sleep.
