SAD 25, or Seasonal Affective Disorder 25, is a type of depression that occurs at specific times of the year, typically 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 difficulty concentrating. The condition 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 SAD 25 often include light therapy, where individuals are exposed to bright artificial light to mimic natural sunlight. Other approaches may involve psychotherapy and medication, such as antidepressants. Understanding and addressing SAD 25 can help individuals manage their symptoms and improve their overall well-being.
