Causes and risk factors
The exactcauseof SAD is n’t know – the groundwork for mental wellness conditions is often complex , with no single root – but it ’s wide theorized thatchanges in sunlightexposure may play a character .
For example , sunlight has a important influence on ourbody clock , or circadian rhythm , which governs many functions within the dead body . Since there ’s broadly less photograph to sunlight in the wintertime months , it ’s thought that this could interrupt the body clock and thus lead to symptoms of winter - pattern SAD .

The source call for larger clinical trials and also further investigation into the effectiveness of treating SAD in the long condition .
Antidepressantsmay also be dictate as atreatment , though it ’s important to note that it can take up to 4 to 6 weeks for their effects to fully kick in , and for many people , it can postulate a snatch of trial and error to find the medication that works best for them .
