Does dehydration cause vasodilation?
I am not 100% sure if dehydration could cause vasodilation (swelling of a blood vessel), although it does make sense. As the temperature of the body rises, the blood vessels expand to release heat quicker. If one becomes dehydrated, and is then covered in ice packs, they may experience vasoconstriction, causing the blood vessels to constrict and hold heat in more, which would be unwanted.So if you were asking if dehydration causes dilation of the blood vessels, then yes.
How does vasocontriction reduce heat loss?
Your blood vessels will constrict, which means that your blood will flow closer to the centre of your body and nearer to your heart which will keep you warmer.

This will also cause your cheeks to go pink :).
