Extremely famous and persistent misunderstandings about drinking water

True to Lavie's advertisement, water is an essential part of life. Whether you like to drink water or not, it accounts for about 60% of your body weight and plays an important role in ensuring your body functions to function normally.

But there are some very common misconceptions that still exist in a persistent way. Here are 4 misunderstandings synthesized by Lifehacker technology page.

Myth 1: You need to drink 8 glasses of water every day

This is the advice that almost everyone has. However, American professor and doctor Heinz Valtin said that this advice still lacks scientific evidence.

In fact, your body needs may need more than 8 cups or less than 8 glasses of water per day.

In fact, your body needs may need more than 8 cups or less than 8 cups. No number is the norm and the amount of water to drink changes daily, depending on your physical condition, weight, ambient temperature, daily activities and even food.

So how do we know how much water we need to drink? Before the advancement of science, people relied on a very reliable mechanism to know if they were drinking enough water.That is thirst. Enough drinking enough water to satisfy your thirst is enough.

Second misinterpretation: if you feel thirsty, you are already dehydrated

Strictly speaking, it is true . Thirst occurs due to a decrease in the amount of water in the body. But the problem is that thirst is not something to worry about.

Usually, thirst comes when the body's water content decreases by 2-4%.

Usually, thirst comes when the body's water content decreases by 2-4%. Unless you have kidney problems, this is not worrisome for your body and it is an indicator of when you need to drink water.

Dehydration becomes a health problem because the water level in the body decreases by 5-8%. At this stage, you may feel dizzy, tired and have a dry mouth. Note that when exercise, we are also thirsty and lose more water. If you want to be dehydrated, remember to drink a glass of water after 20 minutes of heavy exercise is enough.

Myth 3: Sports drinks are the best option after practice

This depends. Sports drinks contain a lot of electrolytes (salt ions) that help the body replace salt ions lost through sweat. Electrolytes are important: they are things that are needed for nerve function, help maintain blood pH levels and many other effects.

Sports drinks are the best option after training, depending on the intensity of your workout.

But sports drinks are really only needed if you exercise for a long time, such as long distance or many hours of cycling in the sun. If only normal practice with not too high intensity, filtered water will be a better choice.

Myth 4: water will release toxins from the body

Not really . Drinking enough water ensures the body's digestive mechanism works correctly, including natural detoxification processes for the liver and kidneys. But this mechanism works well when they have enough water. Drinking any additional amount of water does not help this process work more efficiently. In fact, drinking too much water can prevent the body's natural detoxification process. It reduces the concentration of salt in the blood, is harmful to the liver and kidneys and prevents the normal functioning of these two parts.

Misinterpretation 5: Drinking bottled water is the best

Bottled water, pure water is a convenient solution that many families choose to save time. However, many people are concerned about the water source of production facilities. Units that use tap water and untreated well water will slowly damage health.

Myth 6: Drink soft drinks to replace filtered water

People with a history of kidney stones should not drink if they do not want to get worse.

Many people have a habit of drinking fresh water regardless of carbonated drinks or fruit juices to replace filtered water when thirsty. Because they found drinking water bland, no taste.

But they do not know the ingredients in fresh water will cause calcium ions in the bones to move everywhere in the body, making the amount of calcium in the urine increase. Therefore, people with a history of kidney stones should not drink if they do not want to get worse.
