Explanation:
Detailed explanation-1: -Shrinking the diameter of blood vessels that supply the skin, a process known as vasoconstriction, reduces blood flow and helps retain heat.
Detailed explanation-2: -Skin-to-skin contact helps regulate a baby’s temperature. When mom and baby are skin to skin, the mother’s chest temperature adjusts to warm up a cool baby, or cool down a too-warm baby. This phenomenon is called “thermal synchrony.”
Detailed explanation-3: -In warm temperatures, these same blood vessels dilate or widen, increasing the flow of blood to the skin surface, thus allowing heat to leave the body, and keeping the core body temperature from rising to a dangerous level.
