When we meet with something we're not familiar with or something frightening, our brain and body start making changes to help prepare us for the unknown. Dr. Kerr says. "For some people, choosing to be scared can be fun. "
What good is fear?
It tells a person to hide, run away, or defend oneself. Faster heartbeat and breathing send more blood and oxygen to the muscles so they are ready when they are needed. Stress chemicals can make a person more alert.
Our memories also help protect us. We keep a close eye on babies because they don't understand what might hurt them. As babies grow, they learn what's unsafe, their brains store those memories. Then their brains use fear to warn them of dangers. "We don't want to be fearless; Dr. Kerr says. "!"
Too much can be harmful
Experiences can lead to long-lasting fears that may stop a person from trying new things. We're born with the ability to feel fear, but a lot of what we're afraid of is learned.
"Being afraid doesn't mean you're weak," Dr. Kerr says. A long-lasting fear can mean you\e had a bad experience, and your brain doesn't want you to have it again. Other people may have no special fear of dogs but may be afraid of other
things, such as heights, snakes, or spiders.
