Why do we jump when we're scared?
When someone scares you suddenly you tend to jump, why is that?

The precursor
your mind tells your muscles to move away in any direction but then your mind relises that it is nothing to freak out about so it sends a message to stop your muscles but it is all sent at different times. you mind says to stop your muscles half way through the movement. you don't actually jump you run to the side then suddnley stop so rather kicking off with your foot to the right you just.... kick off................................. up.

it's a leftover escape mechanism.
something scares you it's instinct to run

tavi m
adrenalin i think

Just look at an animal in the wild who has been startled. They dash off, as quickly as possible! It's a very old reflex, intended to keep us alive in times of danger! It's just that now we don't usually run, just jump.

cause we're scared! what would you rather do, take a nap?

Darth Plagueis
it's the same reason you close your eyes when something is about to hit you...reflexes. your body's natural instinct is to take flight to move away from danger...that is until you develop courage! lol.

maybe its because the bodies nerve response is to cause an action resulting in you getting away from the perceived threat...so our automatic response is to get away, but then we realise its not so big a threat and we stay where we are....so it just ends up being a jump

nick j
I think it's because it sets off a natural reaction to get away from the person or thing that scared you. so you actually jump back away from it so you get some distance and time to react to the situation.

It's called the 'startle reflex' but I'm not sure just why it happens either.

It's called the "flight or fight" response. Your brain triggers your nerves to make your body take action.

it's your fight or flight response to stimuli. You either stay to fight it, or you run - it's an instinctual reaction within each of us to cope with stressors.

I know this is probably not the exact answer you're looking for but it's a nerve reaction.

Getting a little further into the subject, it involves the release of neurotransmitters (norepinephrine also know has adrenaline) which arouses the brain. It's a part of the sympathetic nervous system (SNS) and as someone has already mentioned "fight or flight response" to threats. There's much more to it and better explanation then I can give at the moment:
