Why do hands and feet feel cold in winter?

Cold hands and feet during winter are usually caused by poor blood circulation, especially impaired peripheral circulation. This may be due to the body reducing blood supply to the limbs in order to maintain the temperature of internal organs. The following are some possible causes: 1. Vascular response: In cold environments, blood vessels constrict to reduce heat loss from the body surface, which may cause the hands and feet to feel cold. 2. Low metabolic rate: Individuals with weak constitutions or slower metabolism have reduced capacity for heat production and are more prone to feeling cold. 3. Anemia: Insufficient hemoglobin leads to reduced oxygen transport, potentially causing cold hands and feet. 4. Neurological regulation disorders: Conditions such as Raynaud's disease involve an exaggerated vascular response to cold, causing frequent spasms that impair blood flow. 5. Hormonal effects: Hypothyroidism (insufficient secretion of thyroid hormones) can slow down metabolism, making individuals more susceptible to cold. Daily care includes wearing warm clothing, particularly gloves and socks. Moderate physical activity can improve circulation. Adjusting diet and managing stress are also recommended.
