Science may be able to explain why teens can be so moody!
Researchers at the University of New York say adults have a hormone that normally acts like a tranquilizer. It's released during times of stress to help calm a person down, but they've determined that in teens, that hormone, called THP, actually reverses itself during puberty.
In other words, it increases anxiety in teens, before it stabilizes in adulthood and works like it should to calm the nerves.
