Why do I feel pins and needles when frightened?

Lorrie Dellinger  asked the Naked Scientists:

Hello Naked Scientists, this is Lorrie in Virginia.

I have noticed that when something frightening happens such as a car pulling out in front of me on the interstate, I feel the sensation of pins and needles in my hands and fingers.  This happens very quickly and fades very quickly.  Is this related to adrenaline and the fight or flight response?  If so, how does this sensation of pins and needles prepare the body for fight or flight response?

Love the show!

Lorrie

Isn't the sensation just a side effect?

It is part of the "fight or flight" response to danger your system call on when you are threatened. The addition of neural transmitters to cause quicker reaction times while under stress causes this I believe.
