Shocking! Office workers: excessive water intake can be harmful. During winter, when vitamin intake is low, supplement plain water with fruit or vegetable juices. For office workers, drinking too much water can actually hinder metabolism. Drinking a large glass of water on an empty stomach in the morning, then lying on your right side for 10 minutes before getting up, helps cleanse the gallbladder and liver... Recommended reading:Do I Need Vitamin and Mineral Supplements? How Much Water Should I Drink Daily? Hong Zhongxin, Director of the Nutrition Department at Beijing Friendship Hospital, explains that medical research indicates humans require at least 2500 milliliters of water daily. However, the food we consume already contains substantial moisture—vegetables are 90% water, fruits are 80% water, and meat and fish contain 70% water. Accounting for this, drinking 1500 milliliters of water per day is sufficient.
Thirst should not be the sole indicator for drinking water. Thirst is a signal from the central nervous system indicating dehydration has reached a certain level. Waiting until thirsty to drink is like watering cracked soil—it's too late for optimal health. Adults should aim to drink water at least six times daily.Drinking water on an empty stomach is most effective, as it flows directly through the digestive tract and is absorbed by the body. Additionally, increased water intake promotes sweating and frequent urination, which not only lowers body temperature but also helps eliminate toxins from the blood. Typically, we lose 300 to 400 milliliters of water daily through respiration and skin evaporation during the night.
Therefore, drinking a large glass of water upon waking replenishes fluids lost through metabolism, cleanses the emptied digestive tract, and effectively dilutes blood to reduce viscosity, thereby preventing cardiovascular and cerebrovascular diseases.Office workers should drink less. Medical research indicates that each person needs at least 2.5 liters of water daily. For office workers who spend all day at their desks with little movement, it's best to develop the habit of drinking a small amount of water before sitting down each time. Avoid drinking too much at once, as excess water can linger in the body and hinder metabolism. Since the food we eat daily already contains a significant amount of water, subtracting this, drinking 1.5 liters of water per day is sufficient.
Which water is healthier? With the overwhelming variety of beverages available today, Director Hong Zhongxin emphasizes that plain water remains the best choice. It contains multiple minerals that help regulate bodily fluid balance.During winter, vitamin intake naturally decreases. Adding fruit or vegetable juices to plain water provides both nutrition and vitamin supplementation. However, functional beverages often contain numerous additives, so choose them with caution. Some additives may even increase metabolic burden. Additionally, minimize consumption of carbonated drinks, as they can contribute to osteoporosis and worsen existing conditions.Strong tea and saltwater cannot substitute for drinking water. Strong tea has a diuretic effect, disrupting the body's fluid balance and causing cellular dehydration. Since cells contain very little sodium, drinking saltwater on an empty stomach allows it to enter the bloodstream and tissues but not the cells. Excessively concentrated salt can also dehydrate cells.Drinking repeatedly boiled water may cause cancer. Some people, when cooking noodles or soup, add hot water near the end if the broth seems insufficient or too salty. Others boil lukewarm water from a thermos to prepare milk or instant noodles. While this practice appears economical—saving time, gas, and water—it poses risks.
However, experiments show that repeatedly boiling water converts nitrates into nitrites. Nitrites can transform hemoglobin in the human body into methemoglobin, causing red blood cells to lose their ability to carry oxygen.Consequently, regularly consuming repeatedly boiled water can cause tissue hypoxia, shortness of breath, chest tightness, purple lips and fingernails, or excessive drowsiness. In more severe cases, nitrites entering the body may react with stomach acid and potentially convert into carcinogenic nitrosamines.
