Tears: Bad Loss or Good Loss; A Biological Question?

Well socially it's a very subjective matter, we all have heard that girls cry, and guys never cry. Looking at crying biologically it has been tested and is said to actually be better to cry than to hold tears in. The main studies i have heard of say that holding in emotional tears puts a great amount of stress on the brain, which is important to the body because if we were to hold back emotions it could be bad because our body functions act on emotions, things such as our breathing, and our heart rate and both affected by emotions so if you were to let those emotions out by crying it could possibly be better for your heart, but as far as all the chemicals go i dont think it makes much of a difference. Removing toxic substances by crying doesn't seem like an efficient enough way to remove enough of it from the body to make much of a difference, you would probably get better results by sweating and removing them that way. My conclusion is sure cry every once in a while if you feel the need to, but don't think of it as something good loss or bad loss for your body because it really doesnt make too much of a difference (as you will probably gain those toxic substances again from natural body processes) crying wont do much other than helping your brain release a strong emotional state.
