Stress

Stress has an impact on our minds. But researchers from South Africa, Finland, Great Britain, Estonia, and Latvia have found that it also impacts your external appearance. This is because women with high cortisol levels (the stress hormone) were rated as less attractive by male subjects - without the subjects knowing how high the woman's respective cortisol level was. The scientists explained this: A low cortisol level indicates health, which is ultimately also reflected in your attractiveness.
