how does blood raise body temperature
How to tell if you're having a hot flash: The rise in temperature involved in hot flashes is not severe. During a hot flash, the blood rushing to the vessels nearest the skin may raise skin temperature by five to seven degrees, but core body temperature will not usually rise above a normal 98.6 degrees.he middle layer of the skin, or dermis, stores most of the body's water. When heat activates sweat glands, these glands bring that water, along with the body's salt, to the surface of the skin as sweat. Once on the surface, the water evaporates.
