Time change is not good for physical and mental health. In Spain, keeping the wrong time zone will multiply the effect
In March 2019, the European Parliament voted to completely eliminate the time change of member states from 2021. Bureaucracy, the pandemic and Brexit have made this change impossible. At the same time, citizens continue to suffer the consequences of meaningless political decisions that harm our health.
In the past hundred years, it is said that energy consumption has been reduced and daily productivity increased, thus supporting the introduction of daylight saving time. Other arguments in favor of daylight saving time are that it allows people to enjoy more leisure activities in summer and can increase physical activity.
However, there is no evidence of any of these beneficial effects, and there is ample evidence that time changes can damage physical and mental health.
One 2014 research The study found that people living in Colorado, Utah, and New Mexico have no differences in the way they move around and residents of Arizona.
Research on energy use is also disappointing. A study conducted in Norway and Sweden showed that electricity expenditures can be saved very little. However, another similar study in Indiana in the United States showed that Show an increase in spending.
There is a variable confusion problem with any previous research: it is difficult to distinguish the assumption of time saving from the fact that people spend more time outdoors in summer and not at home. Light.
Internal clock change
Our body follows a natural 24-hour rhythm, and the brain precisely regulates it according to the cycle of light and darkness. This internal clock is located in the hypothalamus, which is part of the suprasplit eye nucleus of the brain.
Our internal clock uses hormones and chemical signals to synchronize the body’s processes. This is the way to regulate the liver function cycle, tissue regeneration and most importantly the immune system.
Changes to the internal clock, even for one hour, can have serious consequences. People who work in shifts that are contrary to the natural cycle of natural light and darkness are at higher risk of cancer, diabetes, and neurodegenerative diseases (such as Alzheimer’s disease, psychosis, and cardiovascular disease).
Every year, all over the world, Increased incidence of heart attacks In spring and autumn, changes occur over a period of about a few months. Similarly, with the passage of summer time, traffic accidents increased and average sleep time decreased, which led to an increase in work accidents and hospital discharges in emergency situations.
jet lag collective
People have gradually realized the importance of keeping the biological clock in sync with the natural cycle in order to maintain health and avoid diseases. The internal clock of the human body gradually adjusts as the earth revolves around the sun, and the light changes with the seasons. However, changing the clock suddenly, from one day to the next, is equivalent to skipping a full three months, which may have a significant impact on our body.
A study also showed People can’t adapt In summer, this change will interfere with our natural adaptation to the season.Timetable change Elevated blood cortisol levels, The stress hormone, is responsible for the chronic inflammatory process.
It seems that all of us are suffering suddenly jet lag, Its immediate effect According to WHO They include indigestion and intestinal disorders, general malaise, daytime sleepiness, difficulty sleeping at night, and decreased physical and mental function.
On average, it takes a person four days to overcome this change, but the impact on children, the elderly, pregnant women or people with chronic diseases is much greater. It may take up to two weeks for these groups to return to normal.
The situation in Spain
The change of time has a greater impact on Spain, a notorious country with the wrong time zone. With the exception of the Canary Islands, Spanish territory has been in the Central European Standard Time (CET) since 1942, when the dictator Francisco Franco supported his ally, Nazi Germany.
This obsolescence means that Spain, which is more west than London, has the same time as the Serbian capital Belgrade, which is 2,500 kilometers east. The social impact is well known. In Spain, people eat and eat later than other neighboring countries, because Spain’s corpses follow their own internal clock, not official time. If the lunch time in London is 1:00 pm, in Spain, it is 2:00 pm. The same is true for dinner. Dinner time in other countries/regions is 8:00 pm, while in Spain, dinner time is 9:00 pm or later.
The prime time for television usually starts around 10:30 in the evening. Coupled with dinner, this means that Spaniards sleep half an hour less than the rest of Europe, and the health of the population is also affected. Now it’s time to change, stop changing the time.
