SAD 26, or Seasonal Affective Disorder 26, is a type of depression that occurs at specific times of the year, often during the fall and winter months when daylight hours are shorter. It is characterized by symptoms such as low energy, changes in sleep patterns, and feelings of sadness or hopelessness. The condition is believed to be linked to changes in light exposure, which can affect the body's internal clock and levels of certain neurotransmitters. Treatment options for SAD 26 may include light therapy, where individuals are exposed to bright artificial light to mimic natural sunlight, as well as psychotherapy and medication. People experiencing symptoms are encouraged to seek help from healthcare professionals to manage their condition effectively.
