Seasonal affective disorder (SAD), also known as seasonal depression, is a type of depression that is related to changes in seasons. It is characterized by symptoms such as low mood, lack of interest in usual activities, fatigue, and changes in appetite and sleep patterns. These symptoms typically begin and end at the same time each year, often in the fall or winter months, and improve during the spring or summer.

SAD is more common in individuals who live in regions with distinct seasons, particularly those who live far from the equator. It is estimated to affect about 5% of the population in the United States. The exact cause of SAD is not fully understood, but it is believed to be related to changes in the body's internal clock, which is regulated by the hormone melatonin. During the winter months, when days are shorter, the body produces more melatonin, which can lead to feelings of depression and fatigue.

Treatment for SAD typically involves a combination of light therapy and antidepressant medication. Light therapy involves sitting in front of a special light box for a certain number of hours each day. This helps to regulate the body's internal clock and can improve symptoms of depression. Antidepressant medication can also be used to treat SAD, although it may take several weeks to see an improvement in symptoms.

In some cases, lifestyle changes such as regular exercise, a healthy diet, and adequate sleep can also help to improve symptoms of SAD. It is important for individuals with SAD to seek treatment from a mental health professional, as untreated SAD can lead to more severe symptoms and a decreased quality of life.
