Why can’t you wait until you’re thirsty to drink water?

Distributed in our blood, brain, muscles and bones, water is an integral part of the human body and the most indispensable macronutrient for the human body. The lack of body water will affect the digestion of food, the transport of nutrients in tissue cells, the redistribution of metabolites transferred to the blood, the timely discharge of metabolic wastes, and the balance of body temperature.

After a healthy adult loses 250-500ml of body fluids, the body will try its best to restore water balance in the shortest time possible. When the center of the brain receives the message that the blood is thickened, the fluid volume in the cells is reduced, and the cells are slightly collapsed, it activates the “hydration” nerve impulse, resulting in the feeling of thirst.

When a person is thirsty, the brain also sends a signal to the pituitary gland in response to the increased water demand in the body, causing it to release hormones to command the kidneys to withdraw some water from the urine and return it to the blood. At the same time, the kidneys themselves respond by concentrating urine and reducing excretion according to the concentration of sodium in the blood flowing through the kidneys.

It can be seen that drinking water when you are thirsty can easily cause the body to become dehydrated.

Chronic low water intake also increases the likelihood of heart problems, stroke, constipation, increased intraocular pressure, high blood pressure, kidney stones, gallstones, urinary tract infections, and pregnancy and childbirth.

Although thirst is a signal that the body is dehydrated, the feeling of thirst lags behind that of dehydration, especially in the elderly, most of the thirst response is slow. It also fails to properly express the feeling of thirst. Therefore, drinking water regularly whether or not thirsty, especially healthy adults who are immersed in learning and working, should always respond positively to thirst throughout the day.

Can drinking more water reduce blood viscosity?

Blood vessels, cells and plasma are all related to blood viscosity. Most of the high blood viscosity is the result of long-term accumulation of multiple risk factors. In very few patients with increased blood viscosity due to plasma factors, drinking more water can help improve this problem. For ordinary people, the most correct and effective way to reduce blood viscosity is to change the unhealthy lifestyle, scientifically and rationally eat and take targeted treatment. If you insist on “drinking water to reduce blood viscosity”, it is easy to cause other health problems due to excessive drinking.

How to drink water properly?

Our water needs depend on factors such as diet, ambient temperature and humidity, geographic location, level of physical activity, and more. There are certain differences between people, even if the same person is in different environmental conditions, the demand for water will also be different.

The human body maintains a balance between water intake and excretion through sophisticated mechanisms. Generally speaking, a healthy adult excretes about 2500ml of water per day through excretion, respiration and skin evaporation, and can take in about 1000ml of water from three meals a day, so we need to supplement 1500-1500ml of water every day. 1700ml (7-8 cups) of water can ensure the balance of water intake and excretion, meet the physiological needs of daily activities such as maintaining life, work and life, and maintain a healthy state.

Which time period should it beDrink water?

Although water is more important than food in sustaining life, there is a fixed time for meals, three meals a day are sometimes not hungry and will not be forgotten, but drinking water is always forgotten. This shows that it is important to drinking water regularly to become a habit.

At the very least, you should do: a glass of water before getting up in the morning, washing up and grooming, a glass of water 30 minutes to 2 hours before and after a meal, a glass of water an hour before going to bed, exercise or exercise Actively increase water intake before and after physical activity. Patients with hyperuricemia or gout should drink at least 2000ml of water per day.

Although, the pseudo-scientific theory that the human body is divided into acid and alkaline is promoted It was overthrown more than ten years ago, but so far, there are still many people paranoid superstitious rumors that the body must maintain an alkaline environment to be healthy. Here to remind everyone, drinking water should try to choose boiled water or fresh tea water, and never believe in water with various concepts such as “alkaline water”.

Water is not a source of nutrients, and the sophisticated human system will not easily change its inherent acid-base properties due to few substances in water.

For people with high blood uric acid levels and gout patients, the so-called therapeutic weak alkaline water contains very little sodium bicarbonate, which does not alkalize urine or relieve gastric acid. It does not make any sense to adjust the physique. Therefore, choosing boiled water or light tea is the best choice to supplement the body’s water balance.
