Water is the source of life and plays a very important role in the body's structure. However, the effects of drinking water at different times are also different. Here are some ways to introduce water for health.

1, drink water before going to bed, can prevent myocardial infarction or stroke

This is real. 70% of the blood is water. When the body is dehydrated, the blood will become concentrated, thick, and affect blood flow. The body must increase blood pressure and reduce blood vessels. While sleeping, the body will still drain water due to breathing, perspiration, etc., but it is not possible to drink water in a timely manner during 7-8 hours. Harvard University research found that 6 to 9 am is the most common cause of myocardial infarction and embolic stroke.

However, in order to prevent some people from getting up in the bathroom in the middle of the night may affect sleep, or the elderly may have the risk of falling, so in addition to kidney stones, as long as there is water 1 to 2 hours before bedtime, and immediately get up in the morning to drink water, also It can achieve the effect of preventing blood vessel obstruction.

It is also advisable to drink water before soaking in hot springs or warm water. These activities can also cause a lot of sweat. When the blood thickens and meets the high temperature environment, it will increase the pressure on the cardiovascular system.

2, drink water together to improve constipation

Drinking a glass of water in the morning can help gastrointestinal motility and improve constipation. If the water is placed on the bed the night before, you can immediately get up and get a drink. The effect is doubled.

Jiang Shoushan, a nephrologist, said that when the body is lying up and sitting up, the intestines will begin to wriggle due to standing reflexes. At this moment, it will be even better to drink about 500cc of water.

Cold water at room temperature can stimulate bowel movements more than warm water, but not lower than room temperature, too cold water will inhibit bowel movements.

As for drinking warm salt water, the doctor said there was no evidence that adding salt helped defecate. In addition, the body has consumed a lot of water during sleep, so drinking salt water will make it more dry, especially when the blood pressure is usually higher in the morning. People with high blood pressure are better off drinking warm boiled water.

3, drink water before exercise, the performance is more dazzling

Most people are accustomed to drinking water after exercise. In fact, the best way is to drink a glass of water before exercise.

Because the purpose of exercise is to train muscles and increase blood circulation. When there is sufficient water in the blood, blood flow will be smoother when exercise, supply sufficient oxygen and nutrients for muscles and cells, so that the exercise performance is better, not easy to fatigue, but also to avoid heat stroke .

4, when drinking, but also to drink plenty of water

It's cool and refreshing to drink beer, don't think it's adding water. Alcohol contains diuretic ingredients. After drinking alcohol, you run the toilet and discharge more than you drink because alcohol has quietly taken away moisture from other parts of your body. And alcohol can dilate blood vessels, increase body temperature, and can easily cause brain and body water shortages.

Therefore, while drinking, do not forget to add water at the same time, you can reduce the thirsty and dry skin after getting up the next day, and also help reduce headaches the next day.

Also don't count tea, coffee, and cola into the daily water you need. Caffeinated beverages, as well as fruit juices containing high amounts of potassium or citric acid, all have a diuretic effect and will carry excess water away from the body. Therefore, these beverages cannot be included in the amount of water you need.

The first glass of water that rises early should not be replaced by juice, milk, coffee, or milk tea. Gastroenterologist Wang Jiaqi said that juice and milk are foods. After drinking, the stomach must start to consume energy to digest these fats and sugars. Drinking tea and coffee on an empty stomach can hurt your stomach.

5, irritability, drink a glass of water, immediately clear

Chinese medicine doctor Le Yingru said that water has the function of stabilizing, nourishing and reducing fire. As long as there is water shortage, there will be dry and hot performance. Except for thirst, the tongue or lips are too red, dry, palms and soles of the feet fever, dry cough, constipation and other conditions, may be the performance of the body's lack of water. In addition, dry eyes or dry skin also require more hydration.

Suddenly feeling tired, emotionally anxious, cranky, or heavy and unfocused, it may be a sign of lack of water. Try drinking a glass of water to rejuvenate. When the old people change their posture and produce dizziness with postural hypotension, it may be caused by lack of blood due to lack of water.

An average of about 2000cc of water is enough for one day, but it should be distributed evenly throughout the day so that the body is not short of water at any time. It is also necessary to make adjustments in accordance with the amount of activity, such as a hot bath, a long time in the summer or stay in the air-conditioned room, should be added to 1 to 2 cups of water.

Le Yingru reminded that some people think that water is hard to drink because of the poor function of water transport and digestion. As long as they drink a glass of water, they feel bloated and uncomfortable. Therefore, if you feel that drinking water is not good, it may be a signal that your stomach is not functioning properly. It is necessary to seek medical treatment for the underlying problems.

6, boiled water after dark, the best water quality

Jiang Shoushan suggested that it is best to boil water at night and the water quality will be the best, because the water pipes have been cleaned with plenty of water all day long. If water is boiled immediately in the morning, the water quality is the worst, because after the water pipe is left standing for a night, it is easy to deposit various dirt and impurities.

In addition, chlorine used to sterilize tap water may cause trihalomethanes that affect the central nervous system when it comes in contact with organic matter in water. So when the boiled water is boiled to 100 degrees, open the lid and cook for 3 to 5 minutes to remove trihalomethane from the water.

But after opening the lid, you don't stand next to it, and you need to open the exhaust fan at the same time. Because trihalomethanes are inhaled when they are volatilized into gas, they are more easily absorbed by the body than when dissolved in water.

Since it was not possible to determine whether there were excessive amounts of lead in the water pipes, Jiang Shoushan reminded the public to consider installing additional water filters.

7, drinking water, equal to no drink, remember to drink small mouth

Whether or not a lot of sweating, as long as the water, you should drink small mouthfuls of mouth, because when you put too much water, the kidney will receive too much water signal, it will speed up the speed of urination, but let drink The water that goes down is lost immediately and there is not enough time to send it to all parts of the body.

And drinking water too fast can also cause flatulence.

8, bottled water is really easy to grow bacteria

The Internet is circulating that after drinking bottled water, a lot of bacteria will grow in one day. This is true. The best way is to bring a kettle.

Wang Jiaqi said that as long as it is a bottled beverage, it is very easy to grow bacteria after opening the cans. Try not to stick your mouth to the bottle, and do not use the same bottle for several consecutive days.

Do not put the bottle on the sun, so that the chemicals in the plastic bottle dissolve into the water.

However, even if it is a kettle, remember to wash the straw and the bottle every day. Stainless steel is better than plastic.
