Why Do Scary Events Make Your Body Feel Jumpy Afterward?
After a scare, your body can feel jumpy because its alarm system may stay switched on for a while! You might feel jumpy, tired, or have trouble sleeping. Talking with a trusted grown-up can help your brain and body feel safe again.
More fun facts
- During a scare, your adrenal glands, which sit on top of your kidneys, release a hormone called adrenaline.
- Adrenaline speeds up breathing and heart rate and sends more blood to your muscles.
- During scary parts of a film, heart rates can jump by up to 42 percent, from 78 to 110 beats per minute.
- Adrenaline lasts a few minutes, so your heart takes a while to calm down after a fright.
- Fear can also sharpen your hearing and tighten your muscles so you are ready for action.
- Adrenaline can even dull pain for a while.
