Water is the source of life, and scientific drinking water is a compulsory course for everyone's health!

That's right, for the sake of our physical health, we need to replenish a certain amount of water every day! For elderly people, replenishing water is particularly important. Let's listen to the precautions for elderly people to drink water together~

Drinking water correctly is healthier

With the growth of age, the ability of the elderly's kidneys to concentrate urine decreases, and the urine volume increases, which is likely to lead to water shortage in the body, slow down the metabolic rate, and reduce the ability of the body to regulate water balance. In addition, the elderly are not sensitive to thirst caused by the rise of osmotic pressure, so they should take the initiative to drink water.

From a health perspective, fresh plain water is the best. It is recommended that healthy adults drink at least 8 glasses of water (approximately 2 liters) per day.

For elderly people, the timing of drinking water is very important. For example, drinking a glass of water in the morning can effectively replenish the water lost at night, promote blood circulation, and quickly restore the brain to a clear state; At the same time, it is also beneficial for emptying toxins and "garbage" in the intestines and stomach, and preventing constipation.

In addition, it is also a good time for elderly people to drink water after lunch and before meals.

However, drinking too much water at once can accelerate urination and increase the burden of renal function on the elderly; Drinking water too quickly and moving too vigorously may lead to headaches, nausea, vomiting, and even elevated blood pressure.

Therefore, it is best to take a small sip slowly, and the water temperature should be the same as room temperature.

Many people find plain water unpleasant to drink, especially for elderly people with reduced taste function, who often feel that their diet tastes bland. At this point, honey water and light salt water are both good choices, which not only enrich the taste but also supplement various minerals, vitamins and other nutrients.

It should be noted that the elderly should not drink pure water for a long time. Barreled water cannot completely replace plain water. It is better not to drink bottled water.

These misunderstandings need to be avoided

Wait for thirst before drinking water?

After losing 250-500ml of body fluids, healthy adults will do their best to restore water balance in the shortest possible time. When the brain center receives information of thickened blood, reduced intracellular fluid volume, and mild cell collapse, it initiates the "water replenishment" nerve impulse, resulting in a feeling of thirst.

When a person is in a state of thirst, the brain will also send signals to the pituitary gland based on the increase in water demand in the body, which commands the kidneys to retrieve some water from urine and return it to the bloodstream by releasing hormones. At the same time, the kidneys themselves also respond by concentrating urine and reducing excretion based on the sodium concentration in the blood flowing through the kidneys.

Although thirst is a signal of water deficiency in the body, the sensation of thirst is delayed compared to water deficiency in the body, especially in elderly people who are mostly slow to respond to thirst. Therefore, whether thirsty or not, it is important to drink water regularly.

Drinking water while eating?

When gastric motility is insufficient and gastric juice secretion is reduced, drinking more water cannot help digestion, but instead can affect the secretion of oral saliva and starch digestive enzymes, as well as the dilution of gastric juice, leading to a decrease in appetite and digestive absorption ability.

Drinking more water can reduce blood viscosity?

Blood vessels, cells, and plasma are all associated with blood viscosity, and the vast majority of high blood viscosity is the result of long-term accumulation of multiple risk factors. A very few patients with increased blood viscosity caused by 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 unhealthy lifestyles, eat scientifically and reasonably, and adopt targeted treatment. If you persist in 'drinking water to reduce blood viscosity', it is easy to cause other health problems due to excessive drinking.

Drink some green tea to fight against aging

The tea polyphenols in tea have a scavenging rate of up to 90% on human oxygen free radicals; Amino acids have the effect of promoting hair growth, preventing premature aging, and preventing osteoporosis and anemia.

Among various types of tea, green tea has the highest content of tea polyphenols and the best anti-aging effect. However, green tea has a cold nature and is not suitable for those with a cold stomach.

Elderly people also pay attention to drinking tea. On the one hand, it is not advisable to drink strong tea. Strong tea contains a large amount of caffeine, which can accelerate the heart rate, increase blood pressure, and increase the burden on the heart; The large amount of tannic acid in strong tea can affect the human body's absorption of iron; Strong tea can also dilute gastric juice and affect digestion; Drinking strong tea before bedtime can easily lead to insomnia.

On the other hand, it is not advisable to drink tea immediately after meals. Tannic acid in tea binds to proteins, slowing down gastrointestinal peristalsis and affecting digestion and absorption. These are all things that elderly people should pay attention to.

Although coffee is good, be cautious

Coffee is beneficial for the health of elderly people, thanks to its antioxidant content. Research has found that drinking a cup of coffee every day in the elderly can help prevent dementia, gallstones, protect kidney function, and lower blood sugar.

However, the daily amount of coffee consumed by elderly people should not exceed 2 cups (approximately 360 milliliters). Excessive consumption can easily lead to adverse reactions such as increased heart rate, nervousness, and high blood pressure. The diuretic effect of coffee can also cause and worsen osteoporosis.

In addition, elderly people also have some taboos when drinking coffee: firstly, it should not be too strong; Secondly, pay attention to calcium supplementation; Thirdly, one should not drink coffee after drinking. It should be noted that elderly people with diseases such as arrhythmia and gastric ulcers should not drink coffee.
