Winter blues likely to be more in people with dark coloured eyes

Seasonal affective disorder, or what is popularly known as winter blues, is likely to affect dark eyed people more than the ones with blue or light-coloured eyes. Published in the Open Access Journal of Behavioural Science and Psychology, the study was done on 175 students. These students were given a questionnaire that estimated the extent to which an individual varies in mood with the seasons. The questionnaire also helped in determining how a person changes in energy, weight, appetite, sleep and much more during the fall and winter season.

On the basis of responses, it was found that people with light or blue eyes experienced lesser winter blues as compared to the ones with dark or brown eyes.

There has been previous research which concluded that dark-coloured eyes are more prone to depression than those with light coloured, blue or green eyes. The reason behind this maybe how much light a person's eyes can process.

People with light-coloured eyes don't absorb as much light as those with brown eyes or eyes with darker pigments. People with light-coloured eyes release less melatonin as compared to people with dark-coloured eyes. Melatonin has been found to make symptoms of depression worse, according to foxnews.com. This mechanism might provide light-eyed people with some resilience to seasonal affective disorder.

It is also important to know that eye colour is not the only factor which affects winter blues. Seasonal affective disorder can also happen to those who spend long time indoors.
