    Halloween is a holiday full of tricks and treats and all things frightening and fun. But what happens when you trade your sweets for a scare? The result is always healthier than candy.

Being frightened can be good for you. Think about your favorite scary books or movies. You are scared but you just can’t resist reading or watching them. Being frightened makes your brain flood with healthy chemical substances that excite your mood and release feelings of great excitement.

When you’re frightened, your body also produces a chemical called oxytocin, which helps people bond with one another. So, if you’re at a haunted(闹鬼的) house with some pals, that experience can help strengthen your friendship. “Watch people walking out of a haunted house, and you’ll see lots of smiles and high fives,” says Dr. Margee Kerr, a sociologist who studies fear.

There is also some evidence that being scared can help a person manage stressful situations. Things like giving a presentation in front of your class or performing in a school play can make us fearful and anxious. But these experiences help build a sort of endurance to fear that makes us more confident. “You become more comfortable with the physical experience of fear, and so you’re better able to work through it during tense situations,” Kerr explains.

Though some haunting may be healthy, it’s important to remember that people experience fear in different ways. What may be fun for one person could be too scary for another. And Kerr notes that kids younger than six and or seven can’t separate real and make-believe, so seeing something frightening could have lasting, negative effects.
