Change of time disturbs man's regular rhythm and deregulation of interior biological clocks – scientists indicate. For this reason, it would be more beneficial for biology to keep permanent winter time. As Patrycja Sciślewska, a neurobiologist from the University of Warsaw, emphasizes, would stay during summertime time – especially in winter months – could lead to a condition resembling permanent jet lag.
On the night of 25 on 26 October, we'll take our watches back
This weekend, the night with 25 on 26 October, there will be a change of time from summertime to winter. The clock instructions will be withdrawn from 3:00 a.m. to 2:00 a.m., which means an extra hr of sleep. The return to summertime time will take place on the last weekend of March.
The question of the legitimacy of switching watches for years has sparked discussion among citizens, politicians and scientists. More and more experts are paying attention to the adverse wellness effects of this practice. Investigations Stanford Medicine (USA) have shown that giving up time and introducing permanent winter time could reduce strokes and reduce obesity.
The biological clock and the rhythm of light
According to the neurobiologist, Patrycja Scislevska au Faculty of Biology at the University of Warsaw, the change of time from a chronobiology point of view is not beneficial due to the fact that it leads to the temporary synchronisation of clocks in the human body.
The rhythm controls the brain. Cross-section nucleus {C:$00FFFF} Suprachiasmatic nucleus, SCN). It receives light information straight from the retina and thus adjusts the body's activity to the time of day. In addition to the main clock in the brain, man besides has a so-called. peripherical clocksother organs, including liver or stomach.
Usually all these clocks are synchronized. The seasonal change in time, however, requires more time for individual organs to adapt to fresh conditions. For a fewer days after changing time, many people feel a failure of well-being, difficulty concentrating and problem sleeping.
Summer time and ‘permanent jet lag’
The phenomenon of jet lag, known for traveling between time zones, has akin biological origins to the effects of moving watches. Even a shift of 1 hr can lead to a regular rhythm imbalance.
To aid the body synchronize after changing time, specialists urge vulnerability to natural light – preferably in the morning. Daylight can scope respective 1000 lux, while indoors seldom exceed respective hundred. The most powerful influence on our biological clock is the blue light with a wavelength of about 480 nm, the most of which is in the morning hours. This is what helps to reconstruct average regular rhythm.
Most Poles for abolishing the change of time
In the public consultation conducted by European Commission A fewer years ago, around 4 million EU citizens took part. The vast majority advocated abolishing the change in time. Among Poles 74.2 percent. respondents supported the permanent summertime time, while 14.8 percent. indicated winter time.
According to an expert at the University of Warsaw, specified results are not surprising, but biologically it is precisely winter time is more natural to the human body. summertime time, although it provides longer, bright evenings, in winter would origin very late sunrises and the request to start the day in the dark.
The human biological clock is closely related to the rhythm of light – man should wake up with its appearance and fall asleep erstwhile it falls dark. In the event of constant summertime time in winter, the natural regular rhythm would be permanently impaired.
