Seasonal Patterns

Seasonal affective disorder is a recognized clinical condition in which reduced winter daylight is linked to persistent low mood and fatigue. The annual shift to standard time places this known seasonal pattern on a national schedule for millions of Americans.

Get outside during daylight hours, stay physically active, and keep a consistent sleep schedule as days shorten. These habits are the steps doctors recommend to help offset reduced sunlight.

The takeaway

Maximizing time outdoors during daylight and keeping a steady sleep routine are practical ways to ease the effects of shorter fall and winter days. Paying attention to persistent low mood or fatigue can help people recognize when to seek support.
