As the winter months bring shorter days and longer nights, about 10 million Americans are expected to experience seasonal affective disorder (SAD). This condition, triggered by reduced sunlight, disrupts serotonin levels in the brain, often leading to symptoms of depression.

SAD can affect anyone but is most common among adolescents and older adults, according to research. Symptoms often resemble those of traditional depression, including low mood, isolation, and anhedonia—the loss of pleasure in daily activities. However, SAD sometimes presents atypically, with increased sleep and appetite, distinguishing it from other forms of depression that often involve insomnia or reduced appetite.

“For certain individuals, SAD manifests as an atypical depression where they sleep and eat more than usual,” explained a medical expert. “What sets it apart is its seasonal nature—symptoms arise during the darker months and fade as sunlight returns.”

The impact of SAD can be profound, affecting work, relationships, and overall quality of life. However, there are steps to mitigate its effects. Experts recommend seeking guidance from a doctor or therapist to explore treatment options, which may include light therapy, counseling, or medication.

Other strategies include maintaining a consistent sleep schedule, prioritizing physical activity, and spending time outdoors during daylight hours. Even small changes, such as positioning workspaces near windows or incorporating more bright lighting at home, can make a difference.

As winter progresses, recognizing the signs of SAD is critical. By taking proactive steps and seeking professional support, those affected can better navigate the season and improve their mental well-being.
