Cold hands and feet are commonly caused by several factors, including cold temperatures, poor circulation, stress, smoking, anemia, and medical conditions such as diabetes, hypothyroidism, Raynaud’s syndrome, and arterial diseases. When it is cold, blood vessels constrict to preserve core body temperature, reducing blood flow to the extremities. Stress releases hormones that narrow blood vessels and reduce circulation. Smoking causes blood vessel constriction and plaque buildup, further reducing circulation. Anemia reduces oxygen transport in the blood, leading to cold extremities. Raynaud’s syndrome causes excessive narrowing of blood vessels in the fingers and toes, triggered by cold or stress, leading to cold, numb, or color-changed fingers and toes. Other medical causes include diabetes, which damages nerves and blood vessels, and hypothyroidism, which slows metabolism and heat production in the body.
If the coldness is persistent, severe, or accompanied by symptoms like numbness, tingling, discoloration, pain, or sores, it is advisable to see a healthcare provider to rule out serious underlying conditions like peripheral artery disease, autoimmune disorders, or severe circulatory issues.
