Winter Depression, often referred to as Seasonal Affective Disorder (SAD), is a type of depression that occurs during the colder months when daylight hours are shorter. Symptoms may include feelings of sadness, fatigue, and changes in sleep or appetite. It is believed to be linked to reduced sunlight exposure, which can affect the body's internal clock and levels of certain neurotransmitters. Treatment options for Winter Depression include light therapy, where individuals are exposed to bright artificial light, as well as psychotherapy and medication. Maintaining a healthy lifestyle with regular exercise and a balanced diet can also help alleviate symptoms.
