Water is an important component of the human body and one of the sources of nutrition. Scientific research has confirmed that as long as a person has water, they will not die from hunger even if they do not eat food for 20 days. However, without water, they will die from dehydration within 3 to 7 days.The human body is composed of approximately 25% solid matter and 75% water, brain tissue contains approximately 85% water, and blood contains approximately 90% water. Human metabolism is carried out through water as a medium, so water, like air and sunlight, is one of the most fundamental elements of life. Water has the function of regulating human body temperature, participating in metabolism, supplementing body fluids, transporting nutrients, maintaining acid-base balance in the body, and maintaining the optimal state of cells.

Water is in motion within the body, constantly exhaling and absorbing new elements, so we need to maintain its dynamic balance within the body. According to experts, in a healthy body, the food obtained every day will provide 1000 milliliters of water, the metabolism of the body will produce 300 milliliters of water, and there will be an external supply of 1500 to 1800 milliliters of water every day. Every day, each person may excrete 1500 milliliters of water through urination, skin evaporation will also consume 500 milliliters of water, and breathing will also excrete 500 milliliters. In this way, each person needs 2500 milliliters of water supply and consumption per day to ensure water balance.

Despite the importance of water in the human body, many people still face the threat of dehydration. Some people mistakenly believe that the body only needs water when the mouth is dry, which leads to widespread and chronic dehydration, followed by health problems. For example, if there is a lack of water, it can cause blood concentration, poor circulation, affect nutrient delivery, and reduce the supply of cellular nutrients. For example, the human body excretes waste from the blood by excreting sweat and urine. If there is a lack of water, the body waste generated by metabolism is not easily excreted from the body. In addition, a lack of moisture may also cause weight gain, decreased sebum secretion, dryness of the skin, increased wrinkles, and so on.

Scientific Drinking Water: Five Needs and Five Don’ts

One is to drink purified water containing minerals, and not directly drink unfiltered tap water or purified water filtered out of minerals.

Unfiltered tap water entering users’ homes through pipelines from the water plant is prone to secondary pollution. Drinking water is also one of the important ways to provide essential minerals (such as calcium and magnesium) and trace elements (such as fluorine) for the human body. The proportion of these elements in natural mineral water is basically the same as that in the human body, and they are easily absorbed by the human body. Lack of these elements in the human body can lead to nutritional imbalance.

The second is to drink regularly and not wait until you are thirsty to think of drinking.

When the body is particularly eager to drink water, its organs are already operating at an extreme level. Experts suggest that it is best to develop the habit of drinking water regularly. Generally speaking, it is best to wake up in the morning, drink a glass of plain water after brushing your teeth, drink one at 10 am, drink another before lunch, drink one around 3 pm, and have another before going to bed at night.

The third is to drink more boiled water and not raw water.

Boiling and boiling water for 3 minutes can evaporate some of the chlorine and harmful substances in the water, while also maintaining the necessary nutrients for the human body. Drinking raw water has many disadvantages, because the chlorine in tap water can interact with the residual organic substances in unburned water, leading to an increased chance of bladder cancer cancer and rectal cancer.

Fourth, drink fresh boiled water and avoid water that has been stored for too long.

Fresh boiled water is not only sterile, but also contains more than ten minerals that the human body needs. But if the time is too long or if you drink water that is reboiled overnight in an automatic water heater, not only do you lose various minerals, but you may also contain some harmful substances, such as nitrite, which can cause nitrite poisoning.

Five is to drink plenty of warm water with salt, not ice water.

In summer, many people choose to drink ice water or cold drinks after sweating heavily. Actually, this is not scientific. Although this may bring temporary comfort, drinking a large amount of ice water or cold drinks can lead to poor sweating and pore drainage, difficulty in body heat dissipation, and accumulation of excess heat, which can easily lead to heatstroke. The correct method is to drink more salt water with a little salt added to replenish the lost salt and water. After saline water enters the body, it quickly seeps into the cells, allowing the body that is constantly sweating and dehydrated to receive timely water replenishment.

How to choose a water purifier

People are paying more attention to water quality, and water purification equipment is also favored by more and more households. However, the quality of water purification brands in the market is mixed, and in the face of hot promotion from various companies, consumers are confused. How should we choose a reasonable and efficient home water treatment system?

One is to choose a professional water purification company with strong capabilities. Identifying big brands not only provides better technical quality assurance, but also provides you with more professional services.

The second is to choose certified and qualified products. At present, many so-called functional water in the market, such as “electrolytic water”, “active water”, “small molecule water”, etc., are not approved by the state.

The third is to identify patented technologies. Powerful professional water purification companies have their own comprehensive research and development system, and the market competition is fierce. Consumers are the fundamental survival of enterprises. In order to compete for market share, professional water purification companies have their own unique product advantages.

The fourth is to choose a water purification company with long-term service guarantee. Even the best water purifier has a lifespan, and the filter element should be replaced regularly after expiration to avoid secondary pollution.
