Sheila asked the Naked Scientists:

Love your show!  Keep up the great work!  

I am a runner and sometimes when I run really hard and become overheated I get the chills.  Why does this happen?

Thanks for your help!
Sheila

What do you think?

It could be that the vigorous exercise causes you to break into a sweat and the rapid cooling that ensues then makes you feel cold.
