When you cry, you will not catch cold just because you are crying. Tears usually drain into the nose through the tear duct at the inner corner of the eye. Crying happens when tears overflow the eyelids and dampen the face, such as when we experience sudden emotion, like sadness or joy, for instance. The muscles in the upper lid squeeze the tear
glands. Tears flow too fast to be drained away into the nose and roll down our cheeks.iology
