AI Summary

Up to one‑fifth of Americans report a mild mood dip as days shorten, colder weather arrives and daylight wanes in winter, according to the Cleveland Clinic. When that low‑energy feeling interferes with daily functioning, it may be diagnosed as seasonal affective disorder, a form of depression tied to reduced daylight exposure. The condition typically emerges during the darker months and resolves when daylight increases.
