How much water can cause poisoning if you drink it at one time

When a person has a cold or fever or a woman has menstrual cramps, many people will advise patients to drink more hot water to relieve pain, but drinking hot water is not as good for the body as we think. There is a lot of knowledge in drinking hot water. If you drink too much water at one time, you may even get poisoned and cause related diseases. So how much water will cause poisoning?

Drinking too much water can cause water poisoning? The average person drinks less than 10 liters a day

Drinking water is not just about drinking plain water. The water contained in foods such as rice, noodle soup, porridge, fruits and vegetables, juice, desserts, etc. can also be considered a way to drink water. As for whether drinking too much water will cause "water intoxication" (hypoosmotic hyponatremia)? In fact, under normal physical conditions, drinking more than 10 liters of water a day will lead to water intoxication. The average person does not drink that much water, so there is no need to worry too much.

What causes drinking water to cause poisoning?

If you drink too much water at one time, it can easily lead to poisoning of the body. Water intoxication is mainly caused by people consuming a large amount of water, which leads to dehydration and hyponatremia. Water intoxication will not cause death, but it is still very harmful to people's health. Under normal circumstances, the water metabolism in people's bodies is mainly regulated by our kidneys. If you drink a lot of water when you are not dehydrated, it will cause kidney hypertrophy. The electrolytes in the body, mainly sodium, will be diluted to varying degrees. Water will penetrate into the skin through the cells, causing cell edema, and then cause water intoxication.

In addition, everyone will find that drinking a lot of water not only does not speed up recovery from the disease, but instead causes problems in other parts of the body. Therefore, drinking water must be scientific. Drinking too much water is not good for your life or body, especially in the cold winter. If you drink too much water, your body's metabolism will be very slow, which will lead to the inability to excrete sweat normally. If a patient with kidney disease drinks a lot of water, it will increase the burden on the kidneys and cause inflammation of the urethra.

Normal people drink water "per kilogram of body weight x 30cc"

For people with normal kidney function, the recommended daily water intake is "per kilogram of body weight x 30cc", which is roughly around 2000cc. Normal kidneys will regulate urine volume based on the body's osmotic pressure, blood sodium concentration, total body water volume, etc. If you drink too much, your kidneys will naturally excrete the excess water; if you drink too little, you will feel thirsty and will naturally look for water to drink.

Patients with poor renal function or those undergoing dialysis need to be more careful about their water intake because the glomerular filtration function of the kidneys has deteriorated and the amount of water they can process has decreased. Chronic kidney disease has various causes and severity. Patients should discuss their appropriate water and electrolyte intake with their nephrologist to achieve the ideal state of proper physical strength, blood pressure, heart rate, breathing, and no edema. In addition to worsening renal function, if you experience lower limb edema or orthopnea, you should also reduce your salt and water intake. If you have heart and lung hydrops, you may even have to control your daily water intake to less than 500cc. Therefore, if you have a medical condition, it is best to consult a doctor before deciding whether to increase or decrease the amount of water you drink.

What are the benefits of drinking water to the human body?

1. Prevent heart disease

If you have a bad heart, you can drink a glass of water before going to bed. This can effectively prevent symptoms such as angina pectoris or myocardial infarction from occurring at night.

2. Help excretion

Under normal circumstances, after a night of metabolism, a lot of toxins accumulate in the body, and a strong external force is needed to push them out to help excrete them. Plain water without any nutrients or sugar is the best choice.

3. Regulate body temperature

Drinking more water every day can not only speed up circulation in the body, but also promote the excretion of sweat from the body, regulate the body's temperature, and quickly excrete toxic substances from the body.
