Tears of joy, for example, contain higher levels of proteins and hormones that are associated with feelings of happiness and contentment. In contrast, tears of sadness contain higher levels of stress hormones and cortisol, which are linked to feelings of distress and sadness.

They also contain antimicrobial substances that help to ward off infections. Additionally, tears have been found to have a calming and relaxing effect on the body and mind.
