Why some people don’t cry?

People who suffer from chronic or melancholic depression may not be able to cry due to their inability to feel anything as a result of their severe depression.

Some people don’t like to cry as they believe it is a sign of weakness.

Some people don’t cry since they believe it would put them in an inferior position with the people surrounding them.

Crying largely depends on the circumstances of a person. If a person is brought up in a tough environment under poor conditions and is used to living a hard life, they might not be easily affected by things that usually make people cry.

Some people hold back their tears so they appear strong to the people around them such as a sick family member.

Some people are used to hiding their emotions and suppressing them for a long time, which prevents them from crying. (See Why do people hide emotional pain?)

Most men around the world are brought up to believe that crying is not manly and thus they should never do it.

Some people prefer to cry when they are alone, which can make it seem like they never cry.

A genetic disorder called Congenital Insensitivity to Pain with Anhidrosis makes a person have high tolerance for pain, which is why they may not cry when they are subjected to severe physical trauma, for example.

People suffering from a rare condition called Familial Dysautonomia (FD), or Riley-Day Syndrome don’t have the necessary reflex to form tears, which results in crying without tears.

Some people may have dry eye syndrome which can occur due to a number of reasons such as contact lenses, LASIK eye surgery and diabetes.

Some people may suffer from an autoimmune disease called Sjögren’s syndrome which affects glands that produce moisture in the body such as tear ducts. (See Why do we feel better after crying?)
