Vasodilation or dilation of the blood vessels is due to a decrease in vascular resistance. As a result of the dilation of blood vessels, blood flow increases. Mammals or warm blooded creatures use vasodilation to move warm blood closer to the surface of the skin where heat can be released. Vasodilation serves as a form of cooling in warm blooded animals.
When blood vessels dilate, their diameter increases, allowing more blood to flow through them. This can help regulate blood pressure, increase blood flow to tissues or organs, and assist with heat loss in the body. Dilation is controlled by various factors, including hormones, neurotransmitters, and local tissue factors.

What solutions soften and expand tissues dilate or open the blood network and breakdown oil and eliminate water.?

What happens in your body when you are hot?
When you are hot, your body increases blood flow to the skin's surface to release heat through sweat and evaporation. Sweat glands produce sweat, which helps regulate body temperature by cooling you down. Additionally, your blood vessels dilate to help dissipate heat.
