摘要
水是人类生存和发展不可缺少的重要物质,是人体的主要组成成分,可参与机体新陈代谢、调节体温、维持体液正常渗透压和电解质平衡。大脑是人类实现认知能力的重要部位,大脑组织中含水比例为85%,水摄入不足或脱水会对认知能力具有一定影响。目前,关于脱水对认知能力的影响以及饮水干预对认知能力的改善作用这两方面的研究尚少且结果不一致。本文主要分析水对认知能力影响的各研究结果和研究设计的限制性因素,为今后的相关试验提出改进建议。
Water is indispensable to human survival and development. It is the main component of human body. The functions of water include participating in body metabolism, modulating normal osmotic pressure, maintaining electrolyte balance and regulating body temperature. Brain is the most important control point of human cognition and the proportion of water is about 85%. Insufficient water intake can grossly affect human cognition. Currently, studies regarding the effects of dehydration on cognitive ability and water intervention on the improvement of the cognitive ability are insufficient to make a conclusion. The results of these studies and the limitations of these studies' design are discussed in this review in order to make some useful suggestions and improvements for future relevant study.
