The easiest way to get water is straight from the faucet. But most people are concerned about the degree of contamination of tap water, and rightfully so. In many areas, the water contains various harmful substances, such as lead, pesticides and chlorine by-products, which exceed all norms. A good solution in this case is to buy a water purifier that filters out lead and other pollutants. Some filters attach directly to the faucet; others are installed as part of the plumbing system. One of the most convenient and economical methods of water purification is a bulk filter, which you can put in a special jug and put in the refrigerator. If you use a filter that removes fluoride from your water, check with your dentist as fluoride is essential for healthy teeth.

Another way is to buy bottled water. There are hundreds of brands, the most popular of which offer spring water and mineral water. Spring water is extracted from underground fresh water sources that form reservoirs on the surface of the earth. Mineral water comes from reservoirs under the rocks. It contains the highest concentration of minerals compared to other water sources. Spring water is another type of bottled water that is taken from an aquifer. Spring water, mineral water, and spring water may still contain some contaminants. For this reason, federal services are tightening the quality requirements for the production of bottled water.

Distilled water, also referred to as purified water, is another type of bottled water. It is purified in the process of evaporation followed by condensation. The disadvantage of such water is the lack of minerals in it. In addition, bottled water often lacks fluoride. However, at present, some manufacturing companies add a mineral complex to the water, making it more nutritious and palatable.

Some prefer seltzer water. This is carbonated water, its bubbles are formed by adding compressed carbon dioxide to it. Most of these products are flavored and contain sucrose or fructose. And although carbonated water can be with pleasure to drink during the day, you’d better refrain from it during class. Bubble gas fills the space in your stomach, giving you a feeling of fullness and, as a result, reducing the total amount of liquid you can drink during and after exercise, and carbon dioxide stimulates the secretion of gastric juice, which is undesirable during exercise.

No matter what kind of water you drink, remember to drink 8-12 cups (2-3 liters) or more of fluid daily to stay hydrated, as well as at least 5 such cups (1 liter) of plain water.
