了解最实用的水合状态测量方法。描述水输入和输出的来源以及水平衡的基础知识。了解水合状态如何影响日常认知表现。水是一种重要的营养素，补充水分对于实现最佳的日常功能是必要的。水平衡在体内受到精确调节，并且存在许多评估水合状态的方法。认知表现衡量一个人的注意力、批判性思维能力和记忆力。传统上，2%或更多的身体缺水被认为会导致认知能力下降；然而，最近的文献表明，即使是轻度脱水（体内水分流失 1-2%）也会损害认知能力。为客户提供有关健康和福祉的咨询应包括传达水对正常身体功能的重要性，以及水对身体和认知表现的影响。
To become aware of the most practical measures of hydration status. To describe sources of water input and output and the basics of water balance. To understand how hydration status may impact daily cognitive performance. Water is a crucial nutrient and euhydration is necessary for optimal daily functioning. Water balance is precisely regulated within the body and many methods exist for assessing hydration status. Cognitive performance measures an individual’s attentiveness, critical thinking skills, and memory. Traditionally a 2% or more body water deficit was thought to produce cognitive performance decrements; however, recent literature suggests that even mild dehydration – a body water loss of 1–2% – can impair cognitive performance. Counseling clients about their health and wellbeing should include conveying the importance of water for normal body functioning, as well as its effects on physical and cognitive performance.
