你是否经常手脚冰冷呢？你知道这是为什么吗？
你有没有面对过这样的问题？自己的双脚和脚趾时常会感觉冰冰凉凉的，甚至晚上要穿睡眠袜睡觉，不然会因为不舒服而睡不好。究竟脚为何总是冰凉呢？下面，就让我们来看一看原因吧。 血液循环不好 脚冷的其中一个原因是因为血液循环不好。久坐不起、吸烟、心脏疾病、高胆固醇等等，这些因素都会导致腿部的血液循环不畅，造成双脚冰凉。 压力大 随着现代社会的生活节奏越来越快，现代人的精神压力也越来越大。当人处于压力和焦虑之下，身体就会产生肾上腺素并注入血液之中，这会使血管收缩，减少血液流向身体远端，导致双脚发冷。 心脏衰弱 双脚冰凉也有可能是心脏衰弱的表现。血液由心脏发出，携带氧气到全身各部位，氧经过燃烧后产生热能，手脚才会温暖。然而，如果心脏衰弱就无法使血液供应到身体末梢部位，这就会造成手脚冰冷的情形。 低温 在低温环境下，双脚发凉也是一种正常的生理现象，这是因为血管会随着气温而热胀冷缩。天气冷时，四肢上的血管就会收缩，这会使血液回流能力减弱，从而导致手脚冰冷。 阳气不足 中医有个说法，阳气是维持生命活力的根本力量，有着温煦身体的作用。如果阳气不足，血液就无法输送到四脚末端，于是人便会畏寒、手脚冰凉。一个人阳气不够的话，就算在睡前做了保暖措施也还是会脚冷。
