8 secrets about water for health that many people do not know

A British study found that teenagers who are dehydrated will have brain shrinkage, and the more dehydrated the body, the more severe the brain shrinkage. To avoid dehydration, the following 8 ways to drink water will help maintain health without spending a lot of money.

1. Drinking water before going to bed can prevent heart attack or stroke

This is true. Blood is 70% water. When the body is dehydrated, the blood becomes thick, sticky and affects blood flow. The body has to increase blood pressure and constrict blood vessels. When you sleep, your body still excretes water through breathing, sweating, etc., but during the 8 hours of sleep, you cannot get up to drink enough water.

Harvard University research has found that 6 to 9 am is the most common time for myocardial infarction and stroke. Experts recommend that, in addition to people with kidney stones, normal people only need to drink warm water 1-2 hours before going to bed, and drink water after waking up, will effectively prevent blood vessel blockage, prevent myocardial infarction, stroke.

2. Drink water after waking up to improve constipation

Drinking a glass of water in the morning helps the digestive tract move and improves constipation. You should put a glass of water next to your bed the night before, and drink water immediately after waking up, the effect will increase many times.

Experts say that when the body is lying down and immediately sits up, the intestines will also start to move reflexively, at this time drinking 500ml of water is best. Warm water temperature equal to body temperature will help stimulate intestinal motility, drinking water that is too cold will inhibit the intestines, not good for the digestive system and overall health.

3. Drink water before exercise, the body is not tired, avoid heatstroke

Most people are used to drinking water after exercising. In fact, the best method is to drink a glass of water before exercising. Because the purpose of exercise is to train the muscles and increase blood circulation.

When there is enough water in the blood, blood flow will be smoother during exercise, oxygen and nutrients in muscles and cells will be provided for better movement, making the body not too tired and avoiding heatstroke. .

4. When drinking alcohol, you should also drink plenty of water.

Alcohol contains diuretics. After drinking alcohol, you will run to the bathroom and flush more than you drank, because alcohol has quietly taken water from other parts of the body. At the same time, alcohol also causes blood vessels to dilate, body temperature increases and easily causes dehydration.

Therefore, while drinking alcohol, do not forget to replenish water, which can reduce thirst and dry skin after waking up the next day, and also help reduce headaches caused by drinking alcohol.

5. When you are tired, drink a glass of water to wake up

Research shows that water has the function of stabilizing, moisturizing and reducing heat. As long as there is a lack of water, the body will show signs of dryness and heat. In addition to thirst, the tip of the tongue or lips is quite red and dry, the palms and soles of the feet are feverish, dry cough, constipation, all of which can be signs of dehydration. In addition, dry eyes or skin also need to be supplemented with water.

If you suddenly feel tired, anxious, irritable, or have a heavy mind and lack of concentration, drinking a glass of water will help restore your vitality. Everyone should supplement 2 liters of water per day, but it needs to be supplemented evenly throughout the day to bring the best effect.

6. Only boil water after dark, best water quality

Experts say it is best to boil water in the evening, and the water quality will be the best, because the water pipes have been washed clean with a large amount of water flowing during the day. Boil water in the morning, the water quality is not good, because the water pipes are left overnight, it is easy to accumulate a lot of impurities and dirt.

Additionally, when chlorine used to disinfect tap water comes into contact with organic matter in the water, it can produce trihalomethanes that affect the central nervous system. Therefore, when boiling water to 100 degrees, remove the lid and continue boiling for 3 to 5 minutes to remove trihalomethanes from the water.

7. Each time you drink water, you should drink small sips.

No matter how much or how little sweat you have, when you drink water, you should drink it in small sips. Because if you drink too much at a time, your kidneys will absorb too much water, increasing the rate of urination, which in turn will cause the amount of water you drink to be quickly lost, and the water will not have enough time to enter other organs. Moreover, drinking water too quickly can easily lead to bloating.

8. Bottled water is actually a breeding ground for bacteria.

After drinking bottled water, the bottle will grow a lot of bacteria in a day, the best way is to bring warm boiled water. Experts say, as long as it is a bottled drink, it is easy to grow bacteria after opening the lid, try to use the drink after opening the lid, do not reuse the bottle.

Also, do not leave the water bottle in the sun to avoid the chemicals in the plastic bottle dissolving into the water. Also, if using warm boiled water, use a glass bottle instead of a plastic bottle.
