Find out everything you need to know about Seasonal Affective Disorder (SAD) with these five surprising facts.
Seasonal Affective Disorder (SAD) is a form of depression that occurs due to lack of light, usually during the winter months. People affected by SAD often have trouble regulating their melatonin and serotonin levels, which control mood and sleep. As winter days become shorter, melatonin increases in the body, making those affected feel more tired, down, and even stressed.
The most common symptoms of SAD include sleep problems, low energy, changes in appetite or weight, losing interest in activities you once enjoyed, and difficulty focusing.
