Water is the source of life. Previously, many guidelines suggested that the amount of drinking water daily should reach 8 cups. Is this drinking water suitable for everyone?Recently, the latest research on the research team from Waseda University in Japan in the "American Clinical Nutrition Magazine" showed that the average daily drinking water per day is 1500 ~ 1800 ml (6 ~ 7 cups), and women are 1300 ~ 1400 ml (1300 ~ 1400 ml (About 5 cups and a half) are the most suitable for the human body.Of course, drinking water is different due to different individuals.
Drinking water is less than 8 cups, unhealthy unhealthy
The water in the human body is not static, but is in a state of dynamic balance. For example, people feel thirsty, hungry and actively drinking water or eating, but they will also use urine, sweating, breathing, feces and other ways.Excess body fluid.The total movement of water in the human body, including intake and loss, is called the water flow turning.The weekly transition rate can evaluate the turnover (excretion) of the body in the body, which is considered to be the gold standard for calculating the daily drinking water.Researchers collected more than 60,000 participants from the large forward -looking Japanese collaboration queue, and the follow -up time was 19.4 years.Based on the computing formula, the peripheral rotation rate of each participant was obtained, and the crowd was divided into a five -point digit of gender specificity according to the value.The results showed that the average daily water turnover rate of women was 2950 ml, and men were 3466 ml.Basic information shows that people with high water conversion rate are often younger, and at the same time, some chronic diseases (such as diabetes and ) incidence is low.
Researchers also explore the relationship between the water turnover rate and the mortality of the whole cause and the mortality of a specific cause, and find that there is a significant L -shaped L -shaped between the lack of moisture and the risk of chronic death and the risk of chronic death.Related.That is, the water in the body is too small or not, and too much is not good.
Completed, it is equivalent to womens daily drinking water between 1275 and 1400 ml, between male drinking water between 1490 and 1570 ml, all due to the minimum mortality rate, most in line with the most in line withThe human body needs.For men in their 20s, the average daily drinking water is 1,500 ~ 1800 ml (6 ~ 7 cups); for women of the same age, the average daily drinking water is 1300 ~ 1400 ml (5 cups and a half).However, various factors such as body shape, age, physical activity, and climate will affect the individuals water demand.
Long -term water dehydration affects health
There are many harm to drinking less water.A forward -looking study conducted by the National CPR Research Institute stated that chronic water deficiency during middle age increased serum sodium, thereby increasing the risk of heart failure in the future.Researchers said that drinking enough water is similar to the effect of reducing salt intake, which is conducive to heart health.
A large -scale crowd observation study published by the "Liuye knife" published by the sub -publication of "Liu Ye Dao" shows that drinking enough water every day may be a delayed aging and a long life.One effective way.Studies have shown that when the middle -aged blood sodium exceeds 142 mmol/liter (normal range 135 ~ 146 mmol/liter), it becomes old and suffer from chronic diseases (including heart failure, dementia, chronic lung disease, stroke, diabetes, peripheral vascular disease, peripheral vascular disease, and peripheral vascular diseases, and peripheral vascular diseases, and peripheral vascular diseases, and peripheral vascular diseases, and peripheral vascular diseases, and peripheral vascular diseases, and peripheral vascular diseases, and peripheral vascular diseases, and peripheral vascular diseases, and peripheral vascular diseases, and peripheral vascular diseases, and peripheral vascular diseases, and peripheral vascular diseases.The risk of early death and early death increased significantly.The author pointed out that the normal high sodium is usually a sign of insufficient water in the body.
A recent study published by European Nutrition Magazine states that for healthy young men, drinking less water daily will cause vascular function when the body is mildly dehydrated.It is comparable to smoking.
Du Junbao research team of the First Hospital of Peking University found that drinking less than 800 ml daily and 8 hours of sleeping time, and3.8 times and 5.9 times higher.
Drink water, drink less drinks
"Chinese Resident Dietary Guide (2022)" pointed out, waterIt is an important part of the diet and the essential material for all life activities. The amount of required is mainly affected by factors such as age, physical activity, and environmental temperature.
Adults with low physical activity levels should drink 1500 ~ 1700 ml (7 ~ 8 cups) per day.Under the conditions of high temperature or high physical activity level, drinking water should be appropriately increased.Drinking too much water or too much will cause harm to human health.The water and dietary soup from the food account for about 1/2. It is recommended to drink water and overall diets (including water, soup, porridge, milk, etc.) in the day, a total of 2700 ~ 3000 ml of water intake.There is no time limit for drinking water, and it is possible at any time.
It should be noted that sugary drinks cannot replace water. The main component is water and add sugar, and the nutritional value and nutrient density is low.Excessive intake of sugary drinks can increase the risk of caries, ultra -weight obesity, type 2 diabetes, and abnormal blood lipids.
