Here's how to make the most of your time and combat seasonal mental health issuesĪ 2003 study found getting one hour less sleep for two weeks had the same effect on thinking and motor skills as going without sleep for two full nights.

It can even reduce life expectancy,Ī light box can help people get exposure to artificial sunlight, which may help combat seasonal affective disorder. When our internal clocks are offset from the solar day-night cycle by even one hour we develop what sleep experts call “ social jet lag.” Studies have shown social jet lag increases the risk of metabolic disorders such as diabetes, raises the risk of heart disease and stroke, worsens mood disorders such as depression, affects the digestive and endocrine systems and shortens our sleep duration. The proposal has been endorsed by more than 20 medical, scientific, and civic organizations, including the American College of Occupational and Environmental Medicine, the National Parent Teacher Association, the National Safety Council, the Society for Research on Biological Rhythms and the World Sleep Society.

That internal timer controls not just when you sleep, but also when you want to eat, exercise or work, as well as “your blood pressure, your heart rate and your cortisol rhythm,” Zee added. This cycle has set our circadian rhythm, or body clock, for centuries. Standard time, which we enter when we move our clocks back in the fall, is much closer to the sun’s day and night cycle, Zee said. “Between March and November your body gets less morning light and more evening light, which can throw off your circadian rhythm,” she said. Phyllis Zee, director of the Center for Circadian and Sleep Medicine at Northwestern University’s Feinberg School of Medicine in Evanston, Illinois, also opposes Daylight Saving Time. “And there’s no evidence that your body fully shifts to the new time.”ĭr.
“Your body clock stays with (natural) light not with the clock on your wall,” Klerman said. Elizabeth Klerman, a professor of neurology in the division of sleep medicine at Harvard Medical School. “I’m one of the many sleep experts that knows it’s a bad idea,” said Dr. Studies over the last 25 years have shown the one-hour change disrupts body rhythms tuned to Earth’s rotation, adding fuel to the debate over whether having Daylight Saving Time in any form is a good idea. However, a growing number of sleep experts say the act of moving our clocks forward in the spring is ruining our health. If or when that is the case, we’ll move our clocks forward and leave them that way, permanently living one hour ahead of the sun.
The bill still has to make its way through the US House of Representatives and be signed into law by the President. Florida’s legislature voted to make Daylight Saving Time permanent in Florida in 2018, but it can’t go into effect until it is federal law as well. “The call to end the antiquated practice of clock changing is gaining momentum throughout the nation,” said Senator Marco Rubio (R-FL), who first introduced the bill in the US Senate, in a statement. Not according to the United States Senate, which in March passed the Sunshine Protection Act of 2021 – if it becomes law, Daylight Saving Time will be permanent. Senate passes bill that would make Daylight Saving Time permanentīut are we putting our trust in an unhealthy, outdated idea?
