We often hear that drinking a glass of water in the morning after waking up is a healthy habit that everyone should practice. During a night's sleep, the body loses some fluid. Therefore, after waking up, it is necessary to replenish the water balance in a timely manner. In addition, a glass of water reduces blood viscosity and stimulates blood circulation, which has a beneficial effect on the health of the cardiovascular system.

Drinking a glass of water in the morning is really very important for our body, but many people do it wrong. In this case, they not only do not strengthen their health, but also cause great harm to it! Next, we will learn what not to do when taking your morning glass of water.
Do not drink too fast or too much, otherwise it puts stress on the heart.
Sure, drinking water in the morning is a good habit, but you need to do it in reasonable amounts. Drinking too much water will thin the blood too quickly and put more strain on the heart.
In most cases, myocardial infarction or stroke occurs in the morning. If you suffer from cardiovascular diseases and, in addition, overload your heart in the morning, this can lead to a heart attack.
In addition, drinking too much water on an empty stomach dilutes stomach acid. If you then immediately begin to eat food, it can negatively affect digestion and subsequently lead to stomach diseases.
Therefore, try not to drink a lot of water in the morning. On average, no more than 150 milliliters will be enough for the body, that is, about half a glass. It is also important to drink the water slowly in small sips.
Choosing the wrong drink can harm your heart, kidneys and blood vessels.
There are different opinions about what should be drunk first thing after waking up. Some people prefer to drink salted water, while others add honey to the water. So what will be healthier for the body?
1) Juices, coffee, milk and other drinks - not recommended
Do not replace the first glass of water with juice, coffee, milk, mineral water or other beverages. This will not replenish the fluid balance, but at the same time it will start the process of digestion and assimilation, which will negatively affect the health of the gastrointestinal tract. Moreover, some drinks are diuretic and cause an even greater lack of fluid in the body.
2) Salted water - not recommended
In the morning, the first increase in blood pressure occurs. During this time, the blood is viscous and the ingestion of salt will further increase the blood pressure. In addition, drinking salted water increases your daily salt intake and puts stress on your kidneys.
3) Water with honey is a good choice
Water with honey is an effective remedy for those who suffer from constipation. Please note that honey must be placed in cold or warm water, not in boiling water.
4) Boiled water is the best choice
Plain boiled water does not contain sugar and salt, and therefore will not exert any stress on the kidneys and cardiovascular system. Thus, it is the best choice for most people.
Water that is too hot or too cold increases the risk of stomach cancer
Some people do not have enough time in the morning that they do not wait for the water to cool down and drink boiling water. Others, on the contrary, hastily drink a glass of cold water, thinking that this will cheer them up. However, both approaches are wrong.
Too cold water stimulates the gastrointestinal tract, causing a rapid contraction of the blood vessels in the stomach lining, leading to discomfort and even diarrhea. Therefore, people with stomach problems are strictly prohibited from drinking cold water on an empty stomach. The same applies to those who suffer from cardiovascular diseases.
You can not drink too hot water, as it injures the esophagus, which in the future can lead to cancer. The fact is that the mucous membrane of the esophagus is very delicate, and the use of liquid, the temperature of which exceeds 65 degrees, can cause a burn. If this happens regularly, the normal cell structure is destroyed, after which malignant formations are formed. Therefore, hot drinks with temperatures above 65 degrees were classified in group 2A, that is, probable carcinogens for humans. Don't ignore this fact.
Thus, in the warm season, the temperature of the consumed water should be close to the ambient temperature. In cold weather - the water should be slightly warmer so as not to irritate the stomach lining, but not more than 50 degrees.
Can I drink water before brushing my teeth?
Many people argue that before drinking water in the morning, you must first brush your teeth. Otherwise, bacteria from the oral cavity will enter the body with water.
In fact, this statement is slightly exaggerated. The place of concentration of bacteria is tartar or dental plaque. It can be removed only by physical impact (cleaning and rubbing). The water does not have enough friction to remove plaque. Therefore, you do not need to worry about the fact that a large number of bacteria will enter the body with water. In addition, the acid in the intestines is able to kill these pathogenic bacteria.
Thus, healthy people do not need to think about what to do first - brush their teeth or drink water. However, if you have periodontitis, gingivitis, or other oral diseases, it is best to brush your teeth before drinking water.
