夏季是一个需要多方面注意的“危险”季节,要安全度夏,我们不妨看看下面的几个“当心”——当心水中毒——许多人在出汗后会大量喝水,此时水分经肠胃吸收后又通过汗排出体外,出汗又失去一些盐分,不断地喝水和出汗就会使血液中的盐分越失越多。血液中的盐含量低,吸水能力也就降低,水分就会通过细胞膜进入细胞内,出现低渗脱水而使细胞水肿,人就会出现头痛、呕吐、嗜睡、呼吸及心跳减慢 Summer is a “dangerous” season that requires a lot of attention. To be safe, let’s take a look at the following “Caution” - Beware of water poisoning - Many people drink plenty of water after sweating At this point the moisture absorbed through the stomach and then excreted through the sweat, sweating and lost some salt, and constantly drink water and sweat will make the blood more and more salt. Low salt content in the blood, water absorption capacity will be reduced, the water will pass through the cell membrane into the cell, hypotonic dehydration and cell edema, people will have headache, vomiting, lethargy, breathing and slow heartbeat
