What is seasonal affective disorder (SAD) and how long does it last?

SAD is a type of depression that occurs consistently during the same season each year, usually winter. It's sometimes called "winter depression" because it typically happens between late autumn and spring when there's less daylight.

The reduced daylight levels during these months are thought to trigger symptoms. Interestingly, the farther you live from the equator, the higher your risk for developing SAD.

Some people experience SAD during summer instead, though this is less common. Summer SAD can include different symptoms like agitation, insomnia, and weight loss.

SAD takes longer to diagnose than other forms of depression because you need to have experienced symptoms during the same season for at least two years before a diagnosis can be made.

Common symptoms beyond typical depression signs include:
* Food cravings and weight gain
* Oversleeping
* Social withdrawal (sometimes called "hibernation")

The good news is that SAD is treatable, just like other forms of depression. Since you're living with SAD, working with your healthcare provider on a treatment plan tailored to your seasonal pattern can help you manage symptoms when they arise each year.
