To diagnose SAD, it is important to visit a specialist. The assessment carried out normally involves asking questions to help assess the state of one’s mental health, eating habits, lifestyle, sleeping patterns or seasonal changes in the way one thinks.

The cause of SAD has not been clearly identified. However, reduced exposure to sunlight is believed to influence its onset. This often triggers the production of a hormone called melatonin that makes one feel sleepy. Therefore, an individual suffering from SAD often excretes excess levels of this. Another hormone called serotonin is also secreted. The hormone affects mood, appetite and sleep. Serotonin is secreted in lower levels due to lack of sunlight, resulting to depression.

SAD can be treated through anti-depressant medication, light therapy, talking therapies and lifestyle regulations.
