为什么你总是感到很累

德克萨斯州Health Ben Hogan Sports Medicine的营养学家艾米·古德森注册营养师说道：即使只是轻度脱水--只有2%的正常液体流失--也会对能量水平造成影响。脱水会导致血量减少，使血液变厚，古德森解释道。从而使心脏跳动频率降低、降低氧气和营养物传至肌肉和器官的速度。想计算自己正常需要多少流体？用体重（磅）除以2，然后得到的数字就是你每天应喝的流体量（盎司），古德森建议。

You're not consuming enough iron

铁元素摄入不足

An iron deficiency can leave you feeling sluggish, irritable, weak, and unable to focus. "It makes you tired because less oxygen travels to the muscles and cells," says Goodson. Boost your iron intake to reduce your risk of anemia: load up on lean beef, kidney beans, tofu, eggs (including the yolk), dark green leafy vegetables, nuts, and peanut butter, and pair them with foods high in vitamin C (vitamin C improves iron absorption when eaten together), suggests Goodson. Note: an iron deficiency may be due to an underlying health problem, so if you're experiencing these symptoms of iron deficiency, you should visit your doc.

缺铁会让你感觉迟钝、易怒、虚弱、无法集中注意力。"因为进入肌肉和细胞的氧气量变少，所以你会感到很累，"古德森说道。增加铁元素摄入量、降低贫血的风险吧：多吃瘦牛肉、芸豆、豆腐、鸡蛋（包括蛋黄）、深色绿叶蔬菜、坚果和花生酱，并且与维C含量高的食物搭配食用（一起摄入时，维C能促进铁的吸收），古德森建议道。注意：缺铁可能是由于潜在的健康问题所致，所以如果你有缺铁的症状，那最好还是去看医生。
