Do you need to drink more water in the colder winter?

Drinking water is what we do every day. The human body cannot live without water, and it needs a lot of water every day to maintain the normal metabolism of the body. In summer, people generally drink more water, and in winter, the weather is very cold, so the speed of human metabolism is relatively slow. Some people think it is unnecessary to drink more water. In fact, it is dry in winter, so you should drink more water.

1. Do you need to drink more water as the weather gets cold?

It's hot in summer, and everyone can understand that if you move a little, you will sweat and drink more water. It's cold in winter, and people don't move often. It seems unnecessary to drink so much water. In fact, the colder the weather, the more water you should drink.

People stay in warm rooms and seldom go out for activities, but it doesn't mean that the water consumed by the human body will be reduced accordingly. Hong Zhaoguang, the chief health education expert of the Ministry of Health, calculated an account for us: according to the difference of each person's workload and height, a person needs to consume about10.6 million ml of water every day to ensure the normal metabolism of the human body, while only breathing consumes 300 ml of water every day, sweating needs 700 ml, and defecation needs at least10.6 million ml. In winter, the climate is dry and the air humidity is small, so it is necessary to replenish water. If you drink less water, the blood consistency will be high, and symptoms such as thrombosis will easily occur, causing cardiovascular diseases. In addition, drinking more water in winter can also speed up metabolism and play a role in resisting the cold.

In addition, research shows that as long as 5% of water is lost in the human body and it is not replenished in time, the skin will be dry. Moreover, it is cold in winter, and people like to close doors and windows, which leads to lack of oxygen indoors. At this time, people will feel dizzy, and patients with heart and lung diseases will feel difficulty breathing, which will lead to various diseases. Drinking more water is conducive to the supply of oxygen, breathing smoothly and maintaining good physical condition. Therefore, it is recommended not to wait until you are thirsty to drink water in winter, especially for people who are physically exhausted. The diet is mainly light. If you eat greasy and salty food, you should drink two more cups. In addition, hot tea is the most suitable in winter. Drink two glasses of water after getting up and before going to bed.

2. Is it useful to drink more water when you have a cold?

According to epidemiologists, the statement "Drink more water when you have a cold" is not accurate enough.

In general, a cold is caused by virus infection or secondary bacterial infection. Drinking more water can indirectly eliminate toxins in the body. However, after analyzing the water absorption data of patients with respiratory tract infection for half a century, Australian researchers concluded that many cases not only failed to accelerate their recovery, but also led to other dysfunction after drinking too much pure water. It is not good to drink more water when you have a cold. Why?

Drinking water blindly when you have a cold can lead to dehydration.

When you have a cold, your body will fight the virus by having a fever. This process will cause a lot of water loss in the body, and will also take away electrolyte components such as sodium and potassium. At this time, if only a large amount of pure water is added, the electrolyte elements such as sodium and potassium in the body will be diluted. When the sodium concentration in the body drops too much, people will have symptoms such as dizziness, fatigue and confusion. At this time, the brain will automatically send a signal to discharge excess water in the body through urine, sweat and other means to achieve the need of electrolyte concentration balance in the body, which is called "spontaneous dehydration" in medicine.

Drink plenty of water when you have a cold and replenish electrolytes at the same time.

In this regard, experts suggest that when you have a cold, your body needs to replenish effective water. At the same time, we should also pay attention to replenish enough electrolytes to help relieve cold symptoms. Experts provided us with the formula of self-made electrolyte water. When we catch a cold, we can make electrolyte water according to the proportion of 20g sugar, 3.5g salt, 2.5g baking soda, 1.5g potassium chloride and 1000ml warm water. If you think the formula is too troublesome, you can also directly drink bottled electrolyte drinks instead, such as Poukari Khan. People with colds should keep enough water, but don't drink a lot at once, but drink intermittently. It is best to drink one cup at a time, about 300 ml, and then drink it after a while, so as to keep the body's water balance at all times and not burden the kidneys.

Serious illness is mostly caused by minor illness, so prevention work should be done well.

In addition, it is also important to actively prevent colds. Epidemiological experts believe that dryness is the favorite living environment for cold germs, and colds are mainly spread through droplets, that is, through the mouth and nose. If the mucous membrane of oral cavity and nasal cavity is kept moist, the invasion of cold germs can be prevented to a great extent. Drink plenty of water to replenish electrolytes, keep your body hydrated and electrolyte sufficient, wear a mask to keep your mouth and nose moist, and rinse your mouth with salt water. These simple practices can effectively protect yourself from the cold virus.

The above article introduces the necessity of drinking more water in winter. In winter, many people will have dry skin and easy peeling of their mouths, which is a phenomenon of water shortage. Usually, we must pay more attention to hydration and keep warm in winter. Winter is the season of high incidence of colds, in order to improve the body's resistance and prevent colds and other diseases.
