Glasgow-based GP Margaret McCartney says the NHS Choices website’s advice that people should drink six to eight glasses a day is ‘not only nonsense, but thoroughly debunked nonsense’. She adds that the benefits of the drink are often exaggerated by ‘organisations with vested interests’ such as bottled water brands. Writing in the British Medical Journal, Dr McCartney also points out that research shows drinking when not thirsty can impair concentration, rather than boost it, and separate evidence suggests that chemicals used for disinfection found in bottled water could be bad for your health.
专家McCartney说:“NHS官网上关于每人每天需要喝六到八杯水的建议,不仅仅是毫无意义,根本就是胡说八道。”她补充道,饮水的益处被健康组织“严重夸大”了,而且还隐含了很多商业因素,各种矿泉水、纯净水的厂商、牌子相互竞争而引发的的“血战”。这项研究发表在《英国医学杂志》上,专家McCartney说:“研究显示,当不感觉饥渴的时候喝水可以提高专注力,这种说法有悖现实。而且,用于瓶装水的具有‘杀菌功效的化学物质’还有损害健康的弊端。”
Drinking excessive amounts can also lead to loss of sleep as people have to get up in the night to go to the toilet, and other studies show it can even cause kidney damage, instead of preventing it. Worryingly, Dr McCartney also warns that taking on too much water can lead to a rare but potentially fatal condition called hyponatraemia, which sees the body’s salt levels drop and can lead to swelling of the brain.
