Sunday, Nov. 2, marks the end of daylight saving time for the year, meaning that at 2 a.m. local time, clocks fell back one hour. The twice-a-year tradition also means that, despite many of us gaining an hour of sleep, many of us will lose more daylight time.

Winter fatigue isn’t a failure of willpower; it’s biology. Acknowledge that your body is adjusting to less light, colder weather and slower rhythms. Opt for nourishing foods, consistent movement and a realistic bedtime routine instead of fighting it.

Most smartphones, computers, and smart devices will adjust automatically for the time change, but manual clocks and appliances will need to be reset. After the time change, sunrise will come earlier each morning, while sunset will occur earlier in the evening.
