Seasonal Affective Depressive Disorder or SADD is a condition commonly seen in Northern climates of the United States and Canada and it may be due to a decrease in the amount of sunlight they receive during winter months. How is this condition related to biological rhythms and what process is not being compensated for well enough?
What will be an ideal response?
The change in exposure to sunlight may affect the release of a hormone from the pineal gland known as melatonin. Also, it can drastically lower the amount of vitamin D the skin is making from exposure to ultraviolet light. The body of some individuals does not change its patterns during the winter months, so they do not acclimatize as well as they should and develop signs and symptoms of SADD.
