Clocks will fall back one hour for the end of Daylight Saving Time Sunday morning, which might sound good in the short term to have that extra hour of sleep, but could actually contribute to health and sleeping issues in the days following.

The Centers for Disease Control and Prevention states that Daylight Saving Time disrupts circadian rhythms, which are the daily cycles of numerous hormones and other body functions that prepare us for expected times for sleeping, eating, and activity. Trouble adjusting to the sudden hour change can lead to trouble falling asleep, increasing the risk for mistakes at work or vehicle crashes. For the fall time change, the CDC recommends starting about three days before to gradually move the timing of wakening and bedtime, meals, exercise and exposure to light later by 15-20 minutes each day. This can include keeping the lights dim and avoiding electronic lit screens for about one hour after waking in the morning.
