We always emphasize drinking more water and drinking more water. Drinking plenty of water is really good for the body, but we are not buckets either. Drinking water is also stressful. When you are in these 5 situations, don't drink water first. So how do you drink water correctly?
These 3 situations remind you not to drink plenty of water
Patients with severe viral influenza should not drink plenty of water
After suffering from a cold, keep drinking water, but do not drink plenty of water at a time. Drink water intermittently. Drink about one drink at a time and do not exceed 300 ml. Drink after a certain period of time. Do not drink it one after the other. This puts too much burden on the kidneys. The amount of water a day should not exceed 2000 ml. In this way, the need for regular cold drinking water can be maintained and there will be no impact on respiratory infections.
Heart is not good to drink water should be a small number of times
Experts point out that many people with heart disease found in clinical practice drink plenty of water every day. In fact, this is very dangerous. Because a large amount of water enters the body and is absorbed, it will cause the body fluid volume to increase significantly, making the blood thinner and the blood volume increasing. This leads to an increase in the heart load and the heart has to increase the intensity and speed of blood delivery. This increase in the workload of the heart is not a problem for normal people, but for heart disease patients, their unhealthy heart is often difficult to withstand such changes, it is likely to induce or aggravate the condition.
Do not drink plenty of water for half an hour after a meal
Half an hour after a meal, it is best not to drink a lot of water, so as not to dilute the gastric juice, dilute the stomach acid, and impair the digestive function. Drinking water after a meal and eating soup in a meal can make the digestive juices mix with the food and have a good effect on digestion and absorption. However, some people drink plenty of water after a meal. This is unscientific. After people eat, food occupies most of the gastrointestinal space. If you drink a lot of water, your stomach will be full and you will feel pain. In addition, if people eat too much, drink plenty of water, stomach food is heavy, but also make the stomach sagging or expansion.
When is the best time to drink water?
Early morning and before going out. After getting up early in the morning and drinking a glass of water, the toxins in the body can be quickly buffered. Not only can they sort out some substances in the stomach but also help prevent constipation. When you go out, remember to drink a glass of water, because going out is equivalent to the movement of the body, then as the sweat evaporates, it needs more water to supplement.
Before going to bed at night. Do not drink too much water before going to bed, or frequent nights will affect sleep, but can not drink water, you should take two and then go to bed. Because when the person is asleep, the water in the body is lost, which causes the blood in the blood to decrease and the blood viscosity becomes higher. Drinking a proper amount of water before going to sleep can relieve this phenomenon and reduce the risk of cerebral thrombosis. In addition, it is better for the elderly to have a glass of water by the bedside before going to bed and feel thirsty and need to drink a few mouthfuls immediately.
Half an hour after a meal. Do not drink water immediately after a meal, otherwise it will dilute, dilute the saliva and gastric juice, so that the activity of protease is weakened, affecting digestion and absorption. It is recommended that most people drink water for half an hour after a meal, about 200 ml. Drink small mouthfuls when you drink, otherwise frequent, heavy drinking water is easy to burn. Easy to burn people should be 2-3 hours after a meal, every 20-30 minutes to drink 3-4 small mouth.
Do not drink these five kinds of water in the morning
Overnight tea. If the brewed tea is left for too long, traces of amino acids, carbohydrates, and other substances will become nutrients for bacteria and molds. Not only that, but also tea polyphenols, vitamins, and other nutrients contained in the tea water will be due to storage time. After a long period of time, an oxidation reaction occurs, resulting in a decrease in the antioxidant content of the tea water, which greatly reduces its nutritional and health care value. Therefore, after getting up, the tea that was brewed last night should not be continued to drink.
Light salt water. The reason why light salt water was used as the first cup of water in the morning was mainly because of its ability to relieve constipation. According to Hong Zhongxin, director of the Nutrition Department of Beijing Friendship Hospital, Capital Medical University, it is impossible to treat constipation by simply drinking water. Through reasonable diet adjustments. The sodium intake of modern people is already too much, and if the body does not lack salt, it will drink salty water, which will increase the intake of salt, but it makes people feel thirsty.
People with high blood pressure, cardiovascular and cerebrovascular diseases, and abnormal kidney function should not use light salt water as the first cup of water after getting up, because morning is the first peak of blood pressure increase in human body. Drinking salt water will make blood pressure higher.
honey water. Some people think that drinking a cup of honey water early to help relieve constipation, but fasting is not suitable for drinking. "Honey contains a lot of fructose and glucose, which will increase blood sugar, affect the appetite, affect the breakfast intake." Hong Zhongxin said. In addition, the fructose in honey is converted into glucose through metabolism to be absorbed and utilized by the human body. As a result, the first cup of water in the morning is not used to clean the body's waste, and honey's nutrients cannot be effectively absorbed. Therefore, after getting up, do not drink honey water on an empty stomach. You can drink a glass of warm white water and drink honey water after 10 minutes. You can also use honey as a breakfast and wipe it with bread.
fruit juice. Many women like to drink a glass of freshly squeezed juice in the morning. This is not desirable. The first reason is that because of the sweetness of the juice, an empty stomach will have an impact on the appetite and cannot eat breakfast. Second, the human body prefers a warm environment, especially in the morning. If you eat cold food, it will stimulate the stomach and affect digestion and absorption.
Carbonated drinks. In addition to the carbonated drinks can not provide the water needed to get up early, the body will also accelerate the discharge of calcium in the metabolism, and increase the body's demand for water, it is best not to drink in the morning.
