The basal type serve to lubricate the eye constantly and are usually composed of made up of proteins, oils, and salts. Their purpose is to keep the whites of your eyes white and clean.

Most emotional tears contain natural substances that are not found in basal tears, such as the hormone leucine-enkephalin, an endorphin which acts as a natural pain reliever. Science has also shown that when we cry, our bodies release a stress hormone known as cortisol. This hormone plays a part in helping us to cope with our emotional stress and acts to release built up adrenaline.

Crying is believed to have many benefits, such as releasing mood-enhancing endorphins, as mentioned above, and reducing stress levels. It is good to cry sometimes as it not only has psychological benefits, but also physical ones. It helps to reduce levels of cortisol which is the body’s primary stress hormone and activates the relaxation response in the body. It is almost like an emotional reset, because crying an allow us to let go of any built up negative emotion we are carrying.

In a way, crying is a kind of therapy. We no longer need to hide away in a dark corner we can take the time to allow ourselves to cry if needed and understand that it is normal and natural. Even though tears can often be seen as a sign of weakness, it can be seen as a sign of strength and courage as well.

Above all, crying is both healthy and normal. It is a way of acknowledging our own feelings, allowing us to communicate them, and help bring closure to any emotion. So the next time you need to have a good cry, go ahead. You won’t regret it.
