As winter brings colder temperatures and shorter days, many people experience the “winter blues,” mild, seasonal sadness that lingers through the colder months. For some, these symptoms are more severe and meet the criteria for seasonal affective disorder (SAD), a form of depression marked by changes in sleep, appetite, energy, and weight. In fact, an American Psychiatric Association (APA) survey found that two in five adults report a decline in mood during winter.
The winter blues and SAD are not the same. “Winter blues” is a general, nonclinical term for feeling down during the season, often tied to specific stressors like the holidays or missing loved ones and usually resolves on its own. Many adults report changes when winter arrives, including sleeping more, fatigue, or low mood.
SAD is a form of depression that recurs at the same time each year, most often in fall and winter. It affects about 5% of U.S. adults and can last for roughly 40% of the year, with women affected more often than men.
Reduced sunlight can disrupt circadian rhythms and alter serotonin and melatonin, which are key to mood and sleep. People with SAD may feel persistently sad, lose interest in usual activities, experience changes in appetite and sleep, feel exhausted, have trouble concentrating, and in severe cases, feel hopeless or have thoughts of death or suicide. These symptoms can significantly interfere with daily life but typically ease as the seasons change.
While you can’t control winter weather or daylight, you can support your well‑being with intentional self-care. Consider these tips for managing the winter blues:
While occasional winter blues are common, prioritizing self-care can help improve your mood and resilience. If low feelings last for several weeks or worsen, especially beyond typical seasonal changes, contact a health care provider. If you’re concerned about your mental health at any time, speak with your doctor or a licensed mental health professional, or call the Substance Abuse and Mental Health Services Administration’s National Helpline at 800-662-HELP (4357).
