1. Proper hydration of the body
Water is the most important inorganic component of the body. It has many important functions, including: it supports the process of transformation of matter, facilitates the movement of head mass, cleanses from toxins, transports organic and non-organic components to all cells, and regulates body temperature. Water demand depends on many factors, i.e. age, sex, body weight or fat content. The body needs more fluids with increased physical activity and increased ambient temperature, which is caused by the additional water processes with which the body then moves. Since water takes part in metabolic processes, this fluid needs to be increased by the increase in the amount of water consumed in the body, and then it must be released from the same source of water.2. Dehydration of the body symptoms
The body does not have the ability to store water, so the lack of water in the diet leads to dehydration quickly. The first symptoms occur when water is lost at a level of 1%. Physical fitness decreases, thermoregulation is reduced and appetite is lacking.3. Dehydration of the body effects
Dehydration leads to serious health effects such as: pain and dizziness, impairment of cognitive function, motor function,?? problems with speech, heart rhythm disorders, renal insufficiency, changes in blood pressure, constipation, dry skin, improper use of medicines, impaired secretion of saliva.4. Coffee and tea as a source of water
The United States Department of Agriculture (USDA) has issued a statement recommending that fluids without added sugar be consumed in order to reduce their amount in the diet. However, it does not pay attention to urea-inducing beverages such as coffee and tea. The U.S. Food and Drug Administration (FDA) recommends that healthy adults consume no more than 400 mg of caffeine per day, which is equivalent to about 3.4 cups of coffee.5. Whether coffee and tea are hydrating
The popular myth about the supposed dehydrating effects of coffee and tea is based on the presence of caffeine in the first study by Fisher S. M. et al. Caffeine is a naturally occurring substance found in coffee, tea and cocoa. This substance acts as an inhibitor of sodium retention in the renal ducts, and when administered in large doses (> 500 mg) it acts immediately in the urine. The first study conducted by Fisher M. and others on the diuretic properties of coffee itself showed that caffeine contained this substance in the body may contribute to the development of the body's specific tolerance to the substance. In addition to the use of the drug itself, the experimental study concluded that the effects of drinking caffeine on the body of men and women after consuming caffeine alone could not be significantly increased from 3 mg/kg of water per year. The results of this study showed that the body weight of men who consumed caffeine and other alcoholic beverages, including caffeine, decreased by 4 kg/year.6. The caffeine content of coffee and tea
Tea leaves contain 4.5% more caffeine than coffee beans, with a maximum of 2.5% of caffeine. However, during the production of tea the amount of this compound decreases. The level of caffeination in tea depends on the variety, cultivation conditions, degree of fermentation, type and method of brewing. Namely, 100 g of black tea contains 2.83.8 mg of this substance, whereas 100g of green tea contains only 1.02.1 mg. The caffeine content in coffee also varies and depending on the type of grain, the production process and the way it is brewed. Robusta coffee contains twice as much caffeine as arabica coffee.
