Water occupies more than two thirds of the Earth’s surface. This is why the planet is so unique. More than 95% of all water on the Earth is concentrated in the oceans. From them begins and ends the cycle of water in nature. Each raindrop that falls on the ground returns to the ocean in about a month and a half. Such a water cycle ensures the renewal of fresh water supplies.
By the presence of water, astronomers judge the possibility of life on other planets. Therefore, with such intense attention, the whole world watched the rovers, which found traces of water on Mars. After all, this discovery can be the key to an answer to the long-standing question: “Is there life on Mars?”
Water in Life
Water and Nature
Water is a natural home for many organisms. The underwater world is amazing. There are sea stars, sponges, jellyfish, crustaceans, multicolor fish, and even sharks. No artist can express in all its glory such a multicolor picture.
Water is a universal substance, without which life is impossible. It is an indispensable part of all living things. Plants contain up to 90% of water, and in the body of an adult person, there is about 70% of liquid.
Water and Human Health
Water is the second most vital component necessary for human life after air. The importance of water is demonstrated by the fact that its content in various organs is about 70 – 90%. With age, the amount of water changes but water is still present in all tissues of our body.
Today, more than ever, it is crucial for the human body to receive clean water with a balanced mineral composition. It delivers grease to the joints, stabilizes the temperature. Water is necessary to maintain all metabolic processes. It takes part in the assimilation of nutrients by cells. Digestion becomes possible only when the food acquires a water-soluble form. More than 85% of all metabolic processes in a body occur in the aquatic environment, so the lack of pure water inevitably leads to the formation of free radicals in the blood of a person, leading to premature skin aging, and, as a result, the formation of wrinkles.
Drinking clean water ensures the normal operation of internal organs. It retains the flexibility of your body and helps the penetration of nutrients. Right diet and clean water help to fight overweight.
Water has a very important function of thermoregulatory. It absorbs excess heat and removes it evaporating through the skin and the respiratory tract. It moisturizes the mucous membranes and the eyeball. In the heat and during physical exercises, there is an intensive evaporation of water from the body. A glass of cool clean water, which is absorbed into the blood from the stomach, ensures the timely cooling of your body, protecting against overheating. During a workout in the gym, it is necessary to drink a lot of water in small portions for normal functioning of the organism.
