Everything in moderation. Hypohydration increases sensations of thirst, the release of arginine vasopressin and causes the activation of the renin-angiotensin-aldosterone system to replenish intracellular and extracellular fluid reserves. Hypohydration affects mental and physical performance, but new evidence suggests that hypohydration may also have harmful effects on cardiovascular health. This is alarming because cardiovascular disease is the leading cause of death in the United States. Observational studies have linked low habitual water intake to an increased future risk of adverse cardiovascular events. Specifically, acute hypohydration can reduce endothelial function, increase sympathetic nervous system activity, and worsen orthostatic tolerance. This review is to present the currently available evidence that relates acute hypohydration to altered vascular function and blood pressure regulation.
Water intake can increase energy expenditure directly, independent of hunger and satiety. The researchers concluded that this inexpensive intervention could be useful in helping obese people achieve greater energy expenditure.
A chronic increase in fluid intake can reduce body fat stores. During the experiment it resulted in protein sparing associated with increased lipolysis, ketogenesis and lipid oxidation throughout the body; Insulin sensitivity of glucose metabolism was also affected. This acute metabolic state resembled fasting.
Cognitive impairment and mood changes have also been detected in women and men following mild dehydration. A dehydration of only 1.39% and 1.59% of body mass, respectively. Chronic insufficient water consumption in older adults, in addition to dehydration encephalopathy, which has been associated with cognitive impairment.
Inadequate nutrition, particularly excessive consumption of processed foods, causes obesity in children and also causes excessive sodium consumption, which increases the risk of excessive water loss. In this study, 55% of the children (n = 15) had urinary osmolality values greater than 800 mOsm/kgH 2 O, indicating significant dehydration, and 53% were dehydrated, according to the IVC/Ao index. Children with obesity and dehydration had a significantly higher BMI and percentage of fat mass, and a significantly higher sodium intake from their diet, as well as their sodium/potassium ratio. 24-hour urinary sodium excretion and osmolality values were directly related to percent fat mass and fat mass (in kg) in a simple linear correlation analysis. These results confirm that obesity is related to dehydration. High overall sodium excretion in children with obesity indicates excessive salt intake along with low potassium intake, which is a significant predictor of dehydration, independent of total water intake.
