Daylight Saving Time 2021: Is the Yearly Ritual to Blame for Depression?

Ready to turn your clocks back for Daylight Saving Time? At first, that extra hour of sleep looks delightful. However, the effects it will have on our bodies will take a little getting used to.

Melatonin, an important hormone in the brain, helps to maintain the body's circadian rhythm. Sunlight inhibits the production of melatonin, while darkness increases it. This explains why some people experience more fatigue and grogginess as winter's days become shorter and the nights become much longer.

In fact, 4 to 6 percent of the population may experience a winter depression known as Seasonal Affective Disorder (SAD). It is four times more common in women than men. In a study, a research team found an increase in the number of hospital admissions for depression immediately following the daylight saving time transition. The researchers stated that the 8 percent rise in depression diagnoses was too high to be considered coincidental. Fortunately, there are a few strategies that may help with the time change:

  • Expose yourself to as much sunlight as possible and increase indoor light exposure as well.
  • Gradually make the transition. Go to bed 15 minutes earlier starting prior to the time change.
  • Make sleep a priority and keep regular sleep hours.
  • Consult with your doctor if you have any concerns.

Great info.! I have struggled with the time change-depression thing myself and definitely find it helpful to pay close attention to exercise and being outdoors as much as possible during the day. Great article. I think many people struggle with SAD and don't always even realize what's happening.
Great suggestion about changing your schedule before the time change goes into effect. Thank you!
Was just having a chat about this today! It always takes me some time to adjust!
