Dynamic Adaptation of the Peripheral Circulation to Cold Exposure Article Literature Review in Microcirculation (New York, N.Y.: ) 19(1) August with Reads. Cold hands and feet are a vague symptom or reduced circulation to the extremities which may be entirely normal. Women may present with these symptoms due to hormonal levels often before menopause. Inadequate arterial circulation to the extremities produces hypoxia and pain, so .
Our extremities are the most sensitive areas, the first to experience circulation problems, hence the cold hands and feet sensation associated with low blood pressure. 4) Estrogen fluctuations.

Raynaud's disease is a condition that causes some areas of your body — such as your fingers, toes, tip of your nose and your ears — to feel numb and cool in response to cold temperatures or stress. In Raynaud's disease, arteries that supply blood to your skin narrow, limiting blood circulation to . Nicotine Nicotine is a stimulant, and has a vasoconstrictive effect; which means that that the blood vessels become narrower in response to it, and less blood passes through them. This effect is made most prominent when a vasodilatory action is applied to the tiny capillaries in the hands, feet and other extremities, such as the nose and ears.

Van Someren, in Handbook of the Biology of Aging (Seventh Edition), Autonomic Heat Retention by Peripheral Vasoconstriction. Peripheral vasoconstriction is an important autonomic response to cold exposure, which restricts heat transfer from the core to the environment through the skin.
Peripheral vasoconstriction is more dependent on core than on skin temperature (cf. Bulcao et.
