what causes the feeling of a head rush
A head rush is when an individual becomes momentarily disoriented upon standing up quickly. In minor cases, symptoms such as slight dizziness, dimming vision, or some tingling in the area of the head and neck may occur.
Another common situation known to bring on this condition is overheating the body. Exercising in hot humid conditions, or even just taking a very hot shower or sitting in a sauna too long, can bring on a head rush in some people.
The dizzyness and head rush is sometimes concurrent with a sense of a change in pressure in the head, neck and chest. Sometimes there is brief neck pain or head pain, like a pinched nerve. Sometimes there is a sense of heat and then cold that rushes through my chest, arms or hands.
