Experts Explain Nutrient Deficiencies and Biological Factors Behind Feeling Cold in Winter

Many people, especially women, experience feeling cold in winter due to various biological and nutritional factors. Experts highlight that deficiencies in iron, copper, and zinc can reduce the body's heat production by affecting oxygen transport, enzyme function, and thyroid regulation. Additionally, women's blood vessels constrict more in response to cold, influenced by hormones like oestrogen, leading to colder hands and feet despite normal body temperature. These factors combine to explain why some individuals feel colder than others during colder months.
