How does laughing really hard and feeling extremely sad trigger tears when they’re two different emotions?

In: Biology

There are actually different types of tears!

Basically, your body always tries to stay balanced (homeostasis).

When we have too much of an emotion to an extreme, we begin to cry.

Those tears are different from each other in their chemical makeup. All the signals within our bodies are electrical or chemical (hormones).

When you’re too excited/happy and begin to cry, that’s the body’s way of flushing the excess chemcials out of the body. This way it doesn’t build up more and more and helps return the body to its “natural balance.”
