Causes of SAD | What is seasonal affective disorder?

The exact causes of seasonal affective disorder remain unknown; however, experts believe that it is the lack of sunlight during winter that might affect a part of the brain called the “hypothalamus” and stop it from working properly, which may result in:

  • Overproduction of Melatonin – Melatonin is a hormone produced and secreted by the pineal gland and helps to regulate sleep and mood. During the shorter and darker winter days, the body increases the production of melatonin. Increased production of melatonin makes the person lethargic and sleepy.
  • Reduction in Serotonin levels – serotonin (aka happy hormone) is a hormone produced by the pineal gland and helps regulate mood, appetite, and sleep. Reduces sunlight exposure during the winter days causes a drop in the production of this hormone. Reduction in serotonin levels in the body during the winter season is the main cause of depression.
  • Disruption of Body’s Internal Clock – shorter daylight hours and less sunlight in winter may also disrupt the body’s internal clock (circadian rhythm), this can also lead to feelings of depression.
