The Daylight Savings end on the first Sunday of November. As such, the sun will start setting earlier and it will get darker sooner, yet specialists consider that returning to the natural way is beneficial for people’s health.
Till Roenneberg, German scientist of Ludwig Maximilans University in Munich, considers that during winter the human body better adapts to the sleeping cycle, yet once the daylight savings come into matter starting March the system is again interrupted.
Roenneberg is currently top researcher for a study that observes the effects of time changes on the human body and concludes that human biological clock is far stronger than any clock the Congress sets in place. “The pure social change of time cannot fool the [biological] clock.”
Even though at first glance individuals rejoice at the idea of prolonging their weekend with a “free” hour, scientists consider the time change as very stressful on the human body. A report published in 2008 and conducted by Swedish researchers showed that the number of heart attacks increases in the days following the time change and that people who suffer from sleep deprivation are severely affected by it.
“These transitions can disrupt chronobiologic rhythms and influence the duration and quality of sleep, and the effect lasts for several days after the shifts”, was the conclusion the Swedish researchers Imre Janszky and Rickard Ljung reached for their study concerning health and welfare. Sleep deprivation directly affects the cardiovascular system, as such leaving the human body open for heart complications during the days following the time changes in spring and autumn.
The time switch was first implemented nationwide during the World Wars with the sole purpose of saving energy resources for the belligerent efforts. Up until 2007, the US was switching the time on April and October. Afterwards, the Congress decided to add four more weeks to the daylight period, considering that longer afternoons will determine the people to turn on the lights later on in the evenings. As such the daylight saving period starts three weeks earlier than before and ends one week later.
The clocks will be set back one hour, 2 a.m. becoming 1 a.m., Sunday morning, November 6th.
