Top FDA drug official is trying to hire a friend who’s seeking a bold new warning on antidepressantscan usher in sleep trouble for weeks or longer. Studies have even found an uptick in heart attacks and strokes right after the March time change. There are ways to ease the adjustment, including getting more sunshine to help reset your circadian rhythm for healthful sleep.Daylight saving time begins Sunday at 2 a.m., an hour of sleep vanishing in most of the U.S. The ritual will reverse on Nov. 1 when clocks “fall back” as daylight saving time ends.don’t make the spring switch, sticking to standard time year-round — along with Puerto Rico, American Samoa, Guam and the U.S. Virgin Islands. Worldwide, dozens of countries also observe daylight saving time, starting and ending at different dates. Some people try to prepare for daylight saving time by going to bed a little earlier two or three nights ahead. While getting back on schedule after an hour’s change may not be that difficult for some people, it’s an added challenge for the third of U.S. adults who already don’t get the recommended seven hours of nightly shuteye.The brain has a master clock that is set by exposure to sunlight and darkness. This circadian rhythm is a roughly 24-hour cycle that determines when we become sleepy and when we’re more alert. The patterns change with age, one reason that early-to-rise youngsters evolve into hard-to-wake teens. Morning light resets the rhythm. By evening, levels of a hormone called melatonin begin to surge, triggering drowsiness. Too much light in the evening — that extra hour from daylight saving time — delays that surge and the cycle gets out of sync. Sleep deprivation is linked to heart disease, cognitive decline, obesity and numerous other problems. And that circadian clock affects more than sleep, also influencing things like heart rate, blood pressure, stress hormones and metabolism.Fatal car crashes temporarily jump the first few days after the spring time change, according to a study of U.S. traffic fatalities. The risk was highest in the morning, and researchers attributed it to sleep deprivation. Then there’s the cardiac connection. The American Heart Association points to studies that suggest an uptick in heart attacks on the Monday after daylight saving time begins, and in strokes for two days afterward. Doctors already know that heart attacks, especially severe ones, are a bit more common on Mondays generally — and in the morning, when blood is more clot-prone. Researchers don’t know why the time change would add to that Monday connection but it’s possible the abrupt circadian disruption exacerbates factors such as high blood pressure in people already at risk.Go outside for early morning sunshine that first week of daylight saving time, which can help reset your body’s internal clock. Moving up daily routines, like dinner time or when you exercise, also may help cue your body to start adapting, sleep experts advise. Afternoon naps and caffeine as well as evening light from phones and other electronic devices can make adjusting to an earlier bedtime even harder.But that’s the opposite of what some health groups recommend. The American Medical Association and American Academy of Sleep Medicine agree it’s time to do away with time switches but say sticking with standard time year-round aligns better with the sun — and human biology — for more consistent sleep.
