编辑部:我今年47岁,一到寒冷季节特别怕冷,不知道为什么?读者刘薇刘薇读者:美国专家通过实验得出结论:“对寒冷耐受力低的人的血液中铁元素含量不足,并常伴有甲状腺素水平降低”。女性缺铁原因主要是月经导致铁的损失,产热不够就容易感到寒冷。甲状腺素具有产热效应,它能加速体内大多数组织细胞的气化过程,增加热量,使基础代谢增高,皮肤血液循环加快。酪氨酸是制造甲状腺素的主要原料,碘需要不断由食物提供,酪氨酸则一般在体内自行合成。如果饮食长期缺碘,便会影响甲状腺激素的合成,机体的御寒能力也会因此降低。
Editorial Department: I am 47 years old. I am particularly afraid of cold in the cold season. I do not know why? Reader Liu Wei Liu Wei Readers: American experts concluded through experiments that “the iron content in the blood of people with low cold tolerance Insufficient, and often accompanied by lower thyroid hormone ”. Female iron deficiency is mainly due to the loss of iron caused by menstruation, fever is not enough to easily feel cold. Thyroxine has a thermogenic effect, it can speed up the gasification process of most cells in the body, increase the calories, so that the basic metabolism, skin blood circulation faster. Tyrosine is the main raw material for the production of thyroxine, iodine needs to be provided by food, tyrosine is generally synthesized in the body. If the diet long-term iodine deficiency, it will affect the synthesis of thyroid hormone, the body’s ability to keep cold will therefore be reduced.
