生理学研究表明,中老年人最容易发生体内慢性缺水。这是因为中老年人血浆肾素和肾上腺素水平都呈现进行性下降的状态,心钠素分泌增加,导致体内钠离子不断丢失,使人体对失水的口渴反应减低,造成饮水不足,极易导致慢性脱水。而盛夏时节的气温高、湿度大、人出汗多,更易发生缺水,如果不及时补充水分,有可能给人的健康造成很多危害,甚至威胁到生命的安全。1.导致白内障:人眼内的液体含量较高,在人体缺水时,眼内也会发生改变,引起眼晶状体浑浊而致视力下降。研究显示,曾发生一次急性脱水的老年
Physiological studies show that the elderly are most prone to chronic water in vivo. This is because in the elderly plasma renin and adrenaline levels showed a progressive decline in state, increased atrial natriuretic peptide, leading to continued loss of sodium ions in the body, so that the body’s response to dehydration reduce thirst, resulting in inadequate drinking water, very Easily lead to chronic dehydration. The midsummer season, high temperature, humidity, sweating more, more prone to water, if not timely replenishment of water, may cause many health hazards, and even threaten the safety of life. 1. Lead to cataracts: the higher the liquid content of the human eye, the human body is dry, the eye will change, causing eye lens turbidity caused by decreased vision. Research shows that there was an acute dehydration in the elderly
