A member asked:

My face and upper body warms up suddenly and i feel lightheaded. possible causes?

A doctor has provided 1 answer

Warm and lightheaded: One possible cause is a vasovagal response. Basically, your body has a reaction in which your heart starts beating too slowly or your blood vessels expand. People can become lightheaded and even faint, which is called vasovagal syncope.
