Overview
- Seasonal affective disorder is a form of depression tied to colder months, with NIMH citing persistent low mood, loss of interest, sleep and appetite changes, and, in severe cases, suicidal thoughts.
- Clinicians warn that tall buildings and long workdays reduce exposure to daylight in New York City, which can intensify winter mood problems.
- Evidence-based treatments include morning light therapy for about 20 minutes and cognitive behavioral therapy, with research indicating high response rates when started early in the season.
- Experts recommend maximizing natural light with outdoor walks or sunny windows, maintaining routines, eating well, and making low‑stakes social plans, and they advise seeking professional help if symptoms persist or worsen.
- Help is available through the 988 Suicide & Crisis Lifeline, the city’s Teenspace program offering free therapy for teens with parental consent, NYC Health + Hospitals and NYC Care for low‑ or no‑cost services, university clinics with reduced fees, and NAMI NYC’s referral line.
