As we all know, water is the source of life and plays a very important role in maintaining the normal operation of the human body. However, drinking water is always neglected in life. Especially in summer, the temperature rises and perspiration increases. If you don't replenish water in time, it may cause a serious burden to your body!

What harm will water shortage bring to our health? Why do the elderly fail to replenish water in time? What signals remind us to pay close attention to hydration?

How dangerous is water shortage?

1 Blocking blood vessels

80% of blood is water. When human body is short of water, blood volume decreases, blood viscosity increases, blood supply slows down, blood pressure drops, and cell metabolism drops.

For the elderly, it is easy to be flustered, short of breath, dizzy and fall; If there is coronary artery stenosis, it is easy to cause myocardial infarction or cerebral infarction.

2 affect renal function

The consistency of blood can be adjusted by itself, but the urine volume cannot be adjusted by itself.

Therefore, after excessive sweating leads to water shortage in the body, the frequency of urination will be significantly reduced, and the time of urine in the bladder will be significantly prolonged, which is easy to breed a large number of bacteria, and bacteria will continue to multiply in the bladder, thus affecting the kidneys.

According to statistics, the probability of renal function problems increases obviously in summer, and the number of outpatients with renal colic and hematuria generally increases.

Beware of high incidence in summer: kidney calculi

In kidney calculi, the incidence rate is 5%~ 10%, especially for the elderly, the incidence rate will increase due to reduced exercise and insufficient water.

However, patients with hyperhidrosis, diabetes, hypertension, obesity and other metabolic diseases, patients with long-term bed rest or fractures, and patients with a history of stones have a recurrence rate as high as 50% within 5 years.

In the early days of kidney calculi, due to the small stones, they often felt little, and the impact on the kidneys and urinary system was relatively small; However, with the development of the disease, stones become larger and larger, which can cause hydronephrosis, urinary tract infection and even urinary system cancer. So, don't ignore it!

Kidney calculi's performance:

① Symptoms of pain, one is very painful and the other is chronic dull pain;

② Changes in urine color, such as hematuria;

③ It is related to urinary tract infection and irritation, frequent micturition, urgent micturition and dysuria.

In daily life, you can eat more auricularia auricula, celery and tomatoes to help accelerate the excretion of water in the body and achieve a good diuretic effect, thus preventing kidney calculi.

However, foods with high oxalic acid content such as spinach and mango can increase the concentration of oxalic acid in urine; High-protein foods such as nuts and beans may lead to urinary calcium excretion. These will increase the burden on the kidneys, and people with poor kidneys should eat less.

Barbecue, seafood, beer, animal offal and other high-purity foods are high-risk foods in kidney calculi, which have been avoided by friends in kidney calculi.

Five symptoms of judging whether the body is short of water.

Many people will have questions, don't normal people drink water when they feel thirsty? Why do some people lack water and endanger their health?

Indeed, when water is scarce, the body's own regulatory ability will give a hint of thirst. For the elderly, their organs react slowly, and their senses such as taste and thirst will drop at the same time, so there will be a phenomenon that the body is short of water but not thirsty, and then forgets to drink water. Generally speaking, people over 60 will attract attention.

Once you can't replenish water in time, it will easily lead to dry skin, poor excretion, constipation, dehydration and heatstroke in the elderly. It is more dangerous for the elderly with cardiovascular and cerebrovascular diseases. Therefore, it is very important to learn to judge whether your body is short of water.

1 urine color darkens.

First of all, the simplest way is to judge the degree of water shortage in the body by the color of urine. With the decrease of blood pressure and the lack of water in body tissues, the kidneys of dehydrated people will concentrate urine and even prevent urine from being produced.

Normal urine is clear and light yellow, the urine concentration will increase, the color will gradually deepen, and it will be dark yellow or even amber in severe cases.

2 blush

When the body is short of water, it will also affect the water shortage of brain cells. When the blood vessels in the brain dilate, it will show the symptoms of blushing, sometimes accompanied by fever, which is a relatively mild dehydration symptom. If it develops further, it will be hot and prone to heatstroke.

3 Memory loss

Lack of water will affect the metabolism of brain cells, thus affecting memory and brain thinking, leading to slow response and decline. Especially the elderly suddenly become forgetful, which may be related to lack of water.

4 easy to fatigue

Long-term water shortage will easily lead to the decrease of blood flow and blood pressure, and the oxygen content in blood will also decrease. Without enough oxygen, muscle and nerve function will be weakened, and it is easier to feel tired.

In summer, we often feel uncomfortable, tired, listless and often doze off, which may be a signal that our body is short of water.

5 joint pain

Many elderly people may suffer from joint pain. In fact, it may be caused by lack of water. When human joints move, the joint capsule needs to be lubricated with water. Lack of water will affect the movement and activity of joint capsule, resulting in pain.

Note that if you pay attention to hydration, the symptoms will be improved, that is, there is no joint problem; However, after paying attention to hydration, there is still no improvement. It is recommended to check the joints.

6 midnight leg cramp

Many people will have this experience, leg cramps in the middle of the night, which is also one of the signals of water shortage.

Water is an important part of metabolism. Lack of water will affect the changes of some ions in the human body, such as magnesium ions and sodium ions. Changes in the concentration of these organic ions can lead to muscle spasms.

Pay attention to drinking water, it will hurt your health if you drink it wrong.

Since water shortage is so harmful, drinking more water is definitely no problem. But experts tell us to drink water correctly, otherwise it will be counterproductive and cause water shortage! So, how to replenish water is safer and healthier? What are the requirements for drinking water?

How to choose common drinks?

strong tea

After drinking, feeling thirsty seems to be solved. In fact, because the concentration of strong tea is too high, it may bring more water out of the body, but it is counterproductive. People who like tea suggest to put less tea, as long as it tastes good.

lemon juice

Although it tastes sour, lemonade is actually an alkaline drink. After metabolism in the body, it can increase the level of citrate in urine, which helps to prevent minerals in urine from forming crystals in the kidneys, so it can be used as a drink choice for replenishing water in summer.

fruit drink

Fruit juice contains a lot of sugar. In the process of juicing, the original dietary fiber of fruit is destroyed, which can't break down sugar. Therefore, drinking fruit juice often may cause the conversion of sugar to fat, cause obesity, and may increase the risk of diabetes.

But for some women with urinary tract infection, juice drinks with strong acidity can help reduce the number of bacteria in the urethra and greatly reduce the probability of urinary tract infection. Therefore, women can drink some juice in moderation every day.

Grasp the amount of drinking water, special people need to pay attention.

Dietary Guidelines for China Residents suggest that healthy adults with mild physical activity should drink at least 1200ml of water every day, in addition to the moisture in food. After high temperature, dry air or exercise, the amount of drinking water should be increased appropriately.

Please pay attention to drinking water for special people:

The water consumption of patients with kidney disease or heart disease should be adjusted according to the condition. For example, in the early stage of nephropathy, it is recommended to drink about 1.5~ 1.8L of water every day; For patients with chronic kidney disease, the appropriate amount of drinking water for the whole day = 500ml+ the amount of urine the day before; For patients with kidney disease and severe heart failure, the amount of drinking water should be controlled within 800 ml ... follow the doctor's advice.

In order to ensure adequate urine volume, it is suggested that you can drink 2000-3000 ml of water every day in summer, and pay attention to the rhythm of drinking water. Drink a small amount of water for many times, each time not exceeding 100ml, and each hour not exceeding 1000ml. In addition, in addition to drinking more water during the day, you should also pay attention to drinking water and hydrating before going to bed.

In daily life, we might as well always put a glass of water on the table or at hand to remind ourselves to drink more water. In addition, we can also drink water regularly, such as a glass of water after getting up early and a glass of water after lunch break, to help us form a regular drinking habit.
