3. Why are tears salty?
Almost 99% of tears are water and the rest are non-organic compounds including salt. The amount of salt in your tears depends on the state of the body and the reason why you are crying.
People have the saltiest tears when they are crying because they feel miserable. When a person is crying, their thyroid works more and their heart rate increases. The body experiences tension that is similar to physical activity. This is why our sweat is also salty. cool stuff for guys cool stuff to buy cool stuff for kids cool stuff for girls
