Answer:It is due to the dilation of blood vessels
Explanation:Humidity causes the blood vessels to expand, which increases the flow of blood to the skin's surface.
This further allows fierce heat to naturally escape the body, preventing the core body temperature from rising to hazardous levels.
A person's body's temperature sensors signal the blood vessels in the skin to relax and admit more blood as it gets more heated.
The colder skin receives heat from the peripheral blood flow, which then radiates it into the surrounding air.
As a result, on hot, sunny days, blood vessels widen and more blood is typically lost, whereas on cold, frigid days, blood vessels constrict and less blood flows to the skin's surface.
