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。
