Smoking and drinking alcohol are harmful to health, and we all know this common knowledge. But did you know that drinking water incorrectly is just as harmful to the body? So what are the misconceptions about drinking water in our daily lives?
1. Not cleaning the water dispenser leads to the growth of bacteria
The water dispenser may seem to improve the quality of drinking water, but it actually hides the risk of "secondary pollution". According to the testing data from the national environmental sanitation department, if the cold and hot inner tanks of the bottled water dispenser are not cleaned for three months, a large number of bacteria such as Staphylococcus and Escherichia coli will breed. Therefore, it is best to clean it once a month, and in the summer, it should be cleaned every two weeks.
2. Avoid drinking bottled water frequently
Bottled water is convenient to carry and easy to drink, so many people choose to buy bottled water when going out. However, the polyester bottles used for bottled water contain substances that can cause chronic poisoning in the human body. Especially when bottled water is exposed to high temperatures or left open, harmful substances will slowly seep into the water, posing a risk to health. It is recommended to use a water bottle to fill water when going out, which is both healthy and environmentally friendly.
3. Be cautious about waiting until you are thirsty to drink water to avoid cardiovascular diseases
Many people drink water only to quench their thirst, which is incorrect. Drinking water accelerates the body's metabolism. If the body is dehydrated for a long time, the viscosity of the blood will increase, which can easily lead to cardiovascular diseases. At the same time, if one does not develop a habit of drinking water regularly, the desire to drink water will decrease over time. Therefore, regardless of whether you are thirsty or not, try to drink some water whenever possible during work hours to gradually develop the habit.
4. Regret not drinking water in the morning as you age
The first glass of water after waking up in the morning is truly "life-saving water", especially for middle-aged and elderly people. After a night's sleep, the body produces a lot of metabolic waste. Drinking a glass of water after waking up can reduce the viscosity of the blood and promote blood circulation in the body. The water choices in the morning are generally as follows:
1. Clear water, such as boiled water or mineral water.
2. Diluted saltwater, which can effectively relieve constipation.
3. Diluted lemon water, which helps stimulate appetite.
5. Drinking water before bed reduces the risk of cerebral thrombosis
It is not advisable to drink too much water before bed, but you can have a few sips, especially for the elderly. When a person enters sleep, the water content in the blood decreases, and the viscosity of the blood increases. Drinking water before bed can reduce the viscosity of the blood and thus reduce the risk of cerebral thrombosis. In dry seasons, water can also moisturize the respiratory tract and help us sleep better.
