Your eye color can help know if you're suffering from seasonal affective disorder or winter depression
If cold weather and long nights make you feel uneasy and low, then you're not alone. People who feel down in the dumps during winters may be be going through a phenomenon called seasonal affective disorder or SAD. For some, it can start with feeling low, irritable, and lethargic, but in some cases, the condition can be serious and debilitating.
SAD is actually a recognized form of clinical depression, but apparently, quite a few experts are divided on what causes the condition, with a lot of them questioning even its existence. However, according to new research, it has been found that eye color might actually be one factor determining whether or not you develop SAD.
Though many people might suspect they have SAD, the condition is usually diagnosed using the seasonal pattern assessment questionnaire. The higher people score on the questionnaire, the more serious their condition is. But what actually causes SAD is still debated.
