True
Yes, seasonal depression, also known as seasonal affective disorder (SAD), is related to the change of seasons. It is a type of depression that is related to the seasonal changes, usually occurring in the fall and winter months when there is less daylight.
The exact cause of SAD is not fully understood, but it is believed to be related to the disruption of the body's circadian rhythm, or internal biological clock, which regulates sleep-wake cycles, hormone production, and other bodily functions. The change in the amount of daylight during the fall and winter months can disrupt the body's circadian rhythm, which can lead to symptoms of depression.
The symptoms of SAD can include feelings of sadness, fatigue, difficulty concentrating, changes in appetite or weight, and social withdrawal. Treatment for SAD may include light therapy, where a person is exposed to bright light for a certain amount of time each day, or other forms of therapy such as talk therapy or medication.
