Step-by-step explanation:
Fear acts as an internal danger alarm. It compels you to action and helps you make wise and prudent decisions.
Without fear, you wouldn’t live very long because you wouldn’t be aware of or care about the threats around you. You might dart across a busy road and be incapable of reacting in that split second when you realize that a car is racing toward you. When you get scared, your body reacts physically so that you can handle danger, also known as the fight-or-flight response. Without this fear response when you’re in jeopardy, you wouldn’t have the energy, focus, speed or strength to fight or flee.
Believe it or not, feeling a bit of fear burns more calories than when you are not afraid. As your pulse quickens, your body experiences a surge in adrenaline. Your metabolism goes into high gear and starts to burn sugar and fat, and your heart starts beating faster to get the resources to your muscles. In one study, physiologists at London’s University of Westminster found that when subjects watched horror movies such as The Shining or The Exorcist, they burned an average 113 calories—about the equivalent of what they would burn on a half-hour walk.
