This morning he will sleep one more hour. During the night of Saturday, October 29 to Sunday, October 30, we will have to turn back the clock. Thus, at 03:00 a.m. it will be 02:00 a.m. again and we will go to winter time. But what do the experts say about the time change? What is the best time, summer or winter?
The Spanish Sleep Scientific Society (SES) advises that in Spain there is only one “stable schedule without changes during the year”. But it goes further. It specifies that winter be permanently maintained and the reason is none other than that, with this, greater exposure to sunlight would be achieved during work and school hours.
Scientific studies show that winter time "promotes a more stable biological rhythm, improves intellectual performance and helps reduce the onset of diseases such as cardiovascular diseases, obesity, insomnia and depression," according to the SES.
Why? The internal clock that controls sleep in the brain depends on external factors, such as temperature and light. Light would be one of the most important factors in establishing an orderly and stable sleep-wake rhythm. The Scientific Society maintains that "both darkness in the morning and light at night delay the internal clock, producing a mismatch in it."
So, if summer time were maintained, in the winter time there would be a lack of light in the morning and in the summer there would be excess light at night, something that would considerably misalign said internal clock, causing "low performance and vulnerability to certain diseases" .
Summer and Winter. ☀️❄️
