peripheral vasoconstriction

Peripheral vasoconstriction is the narrowing of blood vessels near the surface of the body, such as in the skin and extremities. This process is controlled by the nervous system and occurs in response to certain conditions, like cold temperatures or stress, to help maintain core body temperature and blood pressure. By reducing blood flow to the outer areas, the body conserves heat and redirects blood to vital organs. While beneficial for short-term survival, prolonged vasoconstriction can lead to cold extremities and decreased oxygen delivery in those areas.
