What Causes SAD?

What Causes SAD?

One theory holds that the increased hours of darkness disrupt the brain chemicals that affect mood, such as serotonin and melatonin. Some experts believe reduced sunlight causes vitamin D deficiencies—but whether that translates into depression is not entirely clear. There have been conflicting studies on whether there’s a causal connection between low vitamin D levels and depression. So when it comes to a clear cause for SAD, the jury’s still out.

Of course, as with any medical issue, talk with your doctor about treatments if you’re dealing with any kind of depression.
