An Overview on the Beneficial Effects of Hydration
Published in Datta Sourya, Debasis Bagchi, Extreme and Rare Sports, 2019
A human body contains approximately 60% or greater water, the largest constituent of the human body. Water/hydration is important for vital physiological and biochemical functions including body temperature, heart rate and blood pressure, as well as for maintaining optimal health, especially for dermal health, hair and nails. In 2004, the Institute of Medicine (IOM) announced the official recommendation related to water/hydration needs. Simultaneously, the Food and Nutrition Board of the National Academies of Sciences, Engineering, and Medicine established the nutrient recommendations on water, salt and potassium to maintain health and reduce chronic disease risk. It was emphasized that an adult woman should consume 2.7 L of water, while an adult man should consume 3.7 L of water per day. Approximately 80% of this water comes from drinking water and beverages, while 20% is derived from food and nutrients.

Given the importance of hydration of the skin, new raw materials are in constant development. This is a very dynamic area in cosmetics and personal care product development, thus there is a clear need to continue to develop and improve the evaluation techniques that are so important to develop moisturizers with excellent efficacy and safety. Hydration is essential for good skin function as well as good sensorial aspects and maintaining a youthful appearance.

Adequate water consumption is often overlooked. Water is very important to maintain skin turgor, oxygenation and tissue perfusion [67]. It also serves as the main transport of nutrients, waste removal, maintenance of body temperature and blood pressure [65]. The estimated fluid for recovering patients is approximately 1ml/kcal/day. Requisites must be adjusted due to insensible losses and the presence of vomiting and diarrhea [68]. Water, soups, milk, juices, fresh fruits and vegetable consumption are recommended to accomplish hydration needs.

Diet is a vital feature of dental health. Maintaining hydration involves drinking water and sugar-free liquids regularly. We encourage patients to avoid drinking very acidic beverages, especially between meals, because a continuous decrease in intraoral pH may be harmful to dental enamel (176). The most acidic ones are energy drinks, regular and diet sodas, juices, and sports drinks (177). Maintaining a stable neutral pH in the oral cavity is essential since this serves to prevent tooth demineralization (178). Patients should avoid “sticky” processed foods (caramels, taffy, etc.) that are rich in sugar that is difficult to remove (130,179). If patients consume a sugary beverage, they should do it in one sitting (over several minutes) rather than sipping it throughout the day. Such an approach aims to prevent repeated exposure of the teeth to sugar and decrease dental pH with each exposure. Moreover, it is advised to use a straw and avoid atypical drinking behaviors such as sipping, swishing, or holding acidic beverages in the vestibule (180).

In relation to the methodology used in the present study, previous research showed that urinary indices, such as urinary osmolality and particularly FWR, represented body water loss as well as, or better than, plasma osmolality (46). Among the urinary indices, FWR is more advantageous than urinary osmolality, because FWR represents a volume, considering the loss of renal capacity with aging, while urinary osmolality is only a measure of concentration, which depends on gender and diet (22). On the other hand, some authors defend serum measures as the gold standard for a definitive diagnosis (47), but there is a lack of consensus regarding the relative efficacy of plasma osmolality versus other hydration status indices (22, 33). In fact, there is no universally accepted method for measuring the hydration status (22), particularly in older people, in whom the early diagnosis of dehydration can be difficult. In older adults, classical physical signs of dehydration, such as weight loss, skin turgor, dry mouth, and capillary refill time may be absent or misleading (48).

The solubility of cystine in urine is about 250 mg/L at a pH of 6.5. This solubility increases as the urine become more alkaline. Acceptable levels of urinary cystine are 250 mg/L or less at a urinary pH of 6.5 to 7. Hydration is the first step in the medical management by increasing fluid intake sufficiently to produce 2–3 L/day of urine. Patients should drink 240 mL of water every hour during the day and 480 mL before bed and at least once during the night. They should monitor the specific gravity of their urine using reagent strips, with a goal of achieving a value less than 1.010 [117]. Dietary modification can help to reduce the risk of stone formation in cystinuria. Low sodium and relatively low animal protein diet can reduce the excess of urinary cystine excretion and production [118].
