As winter approaches and daylight hours shrink, people who are vulnerable to seasonal depression often notice a change in their bodies and brains. The phenomenon, known as seasonal affective disorder, is triggered by the shorter days and darker afternoons that accompany the colder months.
Seasonal depression is a recognised form of mood disorder that follows a predictable pattern, with symptoms typically intensifying during the winter season. Those affected may experience a range of physical and psychological symptoms, from fatigue and lethargy to feelings of sadness or hopelessness.
Experts say that the reduced exposure to natural light can disrupt the body’s internal clock, or circadian rhythm, which in turn can affect mood and energy levels. The loss of daylight is thought to be a key factor in the onset of seasonal depression.
Common strategies to counteract the effects of shorter days include light therapy, regular physical activity, and maintaining a consistent sleep schedule. These approaches aim to restore a healthier rhythm and improve overall well‑being during the darker months.
The PBS NewsHour highlighted this issue in a recent segment, underscoring the importance of recognising the signs of seasonal depression and seeking appropriate support before the winter months deepen.
