Those with blue or light-colored eyes may be less affected by Seasonal Affective Disorder (SAD) compared to those with dark-colored or brown eyes, a study found. Workman also noted this study’s findings echo previous research that concluded those with darker-colored eyes are more prone to depression than those with blue eyes. Additionally, those with light-colored eyes don’t release as much melatonin (a hormone that helps with sleep) as those with dark-colored eyes in the colder months. As a result, “this mechanism might provide light-eyed people with some resilience to seasonal affective disorder,” he wrote, clarifying some people with light-colored eyes may still be affected by the winter blues, however. People who spend too long indoors are also more susceptible to both winter blues and full-blown SAD.
