Hydration is the body's ability to absorb water and to maintain the correct balance of fluid and electrolytes and is essential to human health. Dehydration can adversely affect metabolism, thermoregulation, digestion, and neurological, kidney, and heart function. Aging as well as disease and medications affect water and electrolyte levels in the body and can lead to dehydration in older adults. In this review, we discuss factors contributing to dehydration in older adults, how hydration is measured, and strategies to improve hydration status. We close with a summary of the different areas of focus related to hydration research.
水合作用是人体吸收水分并维持体液和电解质正确平衡的能力，对人类健康至关重要。脱水会对新陈代谢、体温调节、消化以及神经、肾脏和心脏功能产生不利影响。衰老以及疾病和药物都会影响体内的水和电解质水平，并可能导致老年人脱水。在本综述中，我们讨论了导致老年人脱水的因素、水合作用的测量方法以及改善水合状态的策略。最后，我们总结了与水合作用研究相关的不同重点领域。
