Drinking Water Scientifically——The "Water World" in the Human Body

Do you drink water only when you are thirsty? Do you drink beverages as water? Be careful, your body is sending out an alarm! Water is essential for life, but are you really drinking it right? Today, we will teach you how to drink water scientifically and live a healthy life, starting with a glass of water!

01. The "water world" in the human body

Water plays a vital role in the human body.

Water is not only the main component of human cells, but also participates in various chemical reactions within cells, helping to transport oxygen and nutrients, excrete metabolic waste and toxins, maintain the body's acid-base balance and neuromuscular function, making it play a key role in many physiological processes of the human body.

Generally speaking, the proportion of water in an adult's body is between 50% and 60%, but the water content in the human body may vary with age, gender and physical condition.

Among them, infants have the highest water content, about 75%-78%. Adult males have about 60% water content, while adult females have about 50%-55% water content. As people age, the water content of the human body gradually decreases, and the water content of the elderly is about 45%-50%. Therefore, water is a substance that humans rely on for survival.

02.How many glasses of water should you drink every day?

A normal person's daily water intake is closely related to factors such as his or her environment, activity intensity and individual characteristics. Maintaining appropriate water intake is essential for maintaining health.

According to the recommendations of the "Dietary Guidelines for Chinese Residents", under mild climate conditions, adult males with low physical activity levels should drink 1700 ml of water per day and adult women should drink 1500 ml of water per day .

In special circumstances such as high temperatures or when exercising, pregnant or breastfeeding women, infants and young children, you should also adjust your water intake according to your individual situation to avoid lack of water or dehydration, which will affect the body's normal physiological functions and metabolic activities.

03.Have you fallen into these three common water drinking misconceptions?

Part.01

Drink water only when you are thirsty

In daily life, most people have experienced thirst, so people often do not pay much attention to it. When people feel thirsty, it indicates that the body has obviously lacked water, or even is in a state of mild dehydration, and symptoms such as decreased concentration and fatigue may occur, which may affect physical functions.

Therefore, thirst is a signal that the body is dehydrated and you cannot rely solely on it to replenish water. Regular and active hydration is the key to maintaining the body's water balance .

Part.02

Drinks can completely replace water

Although beverages contain water and can temporarily relieve thirst, they usually also contain additives such as sugar, caffeine, pigments, preservatives, etc. Long-term consumption of beverages may increase the risk of obesity, diabetes, cardiovascular disease, etc., and have adverse effects on health.

In addition, the caffeine and sugar in the beverages have a diuretic effect, which will increase the production of urine, may cause the body to lose more water and aggravate the degree of dehydration.

Therefore, you should mainly drink water , drink beverages in moderation, and try to choose sugar-free or low-sugar, caffeine-free beverages to reduce potential risks to your health.

Drinking pure water is healthy

After being filtered, purified water not only removes harmful substances, but also removes minerals that are beneficial to the human body, such as calcium and magnesium. However, the human body needs an appropriate amount of minerals to maintain electrolyte balance in the body to maintain normal physiological functions. If there is a lack of sufficient minerals in the diet, drinking only purified water for a long time will lead to insufficient intake of minerals required by the human body, which may bring some potential health problems.

Therefore, for health reasons, it is recommended not to drink only purified water for a long time. You should insist on drinking a variety of water and combine it with a balanced diet to ensure adequate mineral intake while meeting the water intake needs.

In short, drinking water is no small matter! Let us join hands to more actively, scientifically and comprehensively understand and master the health knowledge of drinking water, improve the health literacy level of drinking water, develop a scientific concept of healthy drinking water, firmly grasp the initiative of health in our own hands, and jointly protect our health!
