When the human hypothalamus detects that body temperature is lower than the setpoint, it initiates a heating procedure: (1) blood vessels in the skin contract (vasoconstriction) to reduce heat loss, (2) skeletal muscles are triggered to contract, causing shivering to generate heat, (3) the thyroid gland is stimulated to secrete hormones that increase metabolic activity and heat production, and (4) the adrenal glands are stimulated to secrete adrenaline, which triggers the breakdown of glycogen into glucose for exothermic energy production.
