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.

Does smoking increase oxygen to the brain and widens blood vessels?
No, smoking does not increase oxygen to the brain; in fact, it reduces oxygen availability. The chemicals in cigarette smoke can constrict blood vessels, impair circulation, and lead to increased carbon monoxide levels in the blood, which further decreases oxygen transport. While some substances in tobacco may initially cause temporary dilation of blood vessels, the overall impact of smoking is detrimental to cardiovascular health and brain function.
