"Hey, Lao Wang, I've quit the habit of drinking strong tea now, my son said that this is not good for the kidneys, so don't drink strong tea. ”
"What? can drinking tea affect the kidneys?"
Uncle Wang and Uncle Zhao have been old friends for decades, and they often get together to play chess and chat when they have nothing to do.
Recently, the wind was gentle and the weather was not pleasant, so the two of them made an appointment to take out chess in the park and "fight for a few rounds". As soon as they met, Uncle Zhao saw the tea cup in Uncle Wang's hand, and he was the first to speak, which was the scene at the beginning.
It turned out that Uncle Zhao was also a strong tea lover before, whether at home or out, he always held a cup of tea.
Once, the son saw in the news that drinking strong tea may increase the burden on the kidneys and cause negative effects, so he advised his father to quit strong tea. I don't know if it's the psychological effect or the problem of strong tea, Uncle Zhao feels that after quitting strong tea, the excretion is smoother than before.
So, Uncle Zhao decisively advised when he saw that his friend was still drinking strong tea.
Before we dive in, let's take a look at the Canadian data report on the negative effects of drinking less water on the body of older people.
Canadian Study: The older you get, the more you should drink water! People who don't like to drink water are susceptible to 5 diseases
In life, more people may pay attention to diet, work and rest, exercise, etc., and often ignore the foundation of life activities - water.
An experimental data from Canada has pointed out that the older people are, the higher the demand for "water", and if they do not like to drink water, they may increase the risk of five types of diseases.
1. Constipation
At a certain age, people's digestive system function is relatively weakened, and the speed of gastrointestinal peristalsis will naturally slow down. In this case, if the water intake is insufficient, it will further cause the gastrointestinal peristalsis to weaken, so that the feces will stay in the intestine for a longer time, and the intestine will absorb the water in it many times, so it will become drier and harder, and it will be difficult to excrete from the body.
2. Stones
As we age, the kidneys' ability to concentrate urine also decreases to varying degrees.
Minerals in urine mainly include calcium, magnesium, oxalic acid, uric acid, etc. Under normal conditions, these minerals are present in the urine in a dissolved state and are excreted from the body as the urine is excreted. However, when water intake is insufficient and the concentration of minerals in the urine reaches a certain critical value, they are prone to the development of stones in the kidneys or other areas.
Stones may move through the urinary tract, causing urinary tract obstruction and obstruction of urine flow, which in turn can induce hydronephrosis and renal impairment. If the condition persists for a long time, it may also progress to chronic renal failure.
3. Urinary tract infection
Scientific drinking water can help dilute the urine, thereby reducing the residue and growth of bacteria gold and toxins in the urethra and bladder.
When the elderly drink too little water, the urine concentration will naturally increase, of course, the concentration of bacteria and toxins is also in a higher state, and the low water intake will lead to a slow urine flow, increase the residence time of harmful substances in the urethra, and naturally increase the risk of urinary tract infection.
4. Cancer
The risk of bladder cancer, prostate cancer, ureteral cancer and other cancers may also increase, and if we take bladder cancer as an example, risk factors such as smoking (which increases the risk of bladder cancer by 2~5 times), chronic inflammatory stimulation, and genetics may increase the risk of bladder cancer.
However, there is also an inconspicuous bad habit, which also increases the risk of bladder cancer to a certain extent, because drinking less water means less excretion and urine concentration, and if there are carcinogens, the contact time with bladder cancer will be prolonged, which will increase the risk of bladder cancer.
5. Blood clots
Insufficient water intake can lead to an increase in the viscosity of our blood, which naturally slows down its flow and increases its retention time in the blood vessels. In this case, red blood cells and platelets in the blood are more likely to clump together, and some harmful substances may cause certain irritation and damage to the vascular endothelium, which greatly increases the risk of thrombosis.
Additional damage - Gout
In fact, not only the five diseases we just mentioned, but also the occurrence of some diseases and drinking water is not a little related, such as: gout; as mentioned many times above, with the increase of age, the metabolic rate of the elderly will decrease, and their body mobility will also decline to varying degrees, so it is necessary to promote the discharge of metabolic wastes in the body by drinking water.
If you don't drink enough water, it may cause the concentration of uric acid in the blood to rise, which will accumulate in the joints or soft tissues and crystallize, forming gout. Gout attacks can cause limited joint movement and pain, especially at night, which can seriously affect the quality of sleep. Long-term, frequent attacks may also lead to chronic inflammation and dysfunction of the joints.
With the growth of age, the body will have various changes, among which the change of water demand can not be ignored, through scientific drinking water, the appearance of the above diseases can be prevented to a large extent, and then maintain the health of the body.
But many people in our lives don't know what scientific drinking water is, for example, the following two ways are common wrong ways to drink water in life, and in the long run, it may lead to kidney damage.
The doctor concluded: The thing that really hurts the kidneys is "drinking water"! 2 drinking habits should be changed as soon as possible
In our daily lives, we are often told to drink plenty of water. But in reality, the way you drink water and your habits also have an important impact on kidney health. Here are two common poor drinking habits that can damage your kidneys.
1. Drink strong tea for a long time
Strong tea is the favorite of many elderly people, but many people ignore its negative impact on the body.
Strong tea contains high caffeine and oxalic acid, and it has the effect of stimulating sympathetic nerve excitation, which can cause renal vasoconstriction, affect the blood circulation of the kidneys, and increase its work burden.
Although tea is good, strong tea needs to be cautious, oxalic acid is high, and the risk of kidney stones increases.
For the sake of kidney health, everyone can drink weak tea in moderation in their daily life, or choose white tea, yellow tea and other teas with low caffeine content. Especially for patients with chronic kidney disease, it is better to drink plain water whenever possible.
2. Drink a lot of water at one time
For many young people, they are often reluctant to get up and pour water to drink because of "laziness", and they finally move once, and then pour water violently, although this way can help "lazy", but it has a negative impact on the kidneys.
And, in order to cater to this bad habit, many manufacturers also produce large-capacity cups, 1500mL, 2000mL, or even larger, which may have unknowingly caused the situation of drinking too much water.
The glomeruli are the foundation of the kidneys, which are mainly responsible for processing excess water and waste products in the blood to form urine. Obviously, if you drink too much water at one time, it can cause a sudden increase in the workload of the glomeruli and overload the renal filtration system.
In the long term, such a persistent state of high load will accelerate the decline of kidney function and increase the risk of some chronic kidney diseases.
Through the above, we have a certain understanding of water scarcity and wrong drinking water. Let's continue to take a look at some of the misconceptions about drinking water in our lives.
If you drink limescale water for a long time, you will get kidney stones? 2 drinking water misunderstandings, don't believe it anymore
1. Drinking limescale water for a long time is easy to get kidney stones?
I believe that many people will find that the kettle for boiling water at home will leave a thick scale after long-term use, which is very difficult to clean, so many people will wonder if drinking these limescale water for a long time will cause kidney stones?
The answer is no.
In fact, limescale is mainly composed of magnesium hydroxide and calcium carbonate, which are substances contained in tap water. As we mentioned above, the main components of kidney stones are oxalic acid, calcium and other substances, and the content of these substances in scale is very low, far from reaching the concentration of kidney stones, so you don't need to worry.
2. Boiled water also has a "shelf life" that cannot be drunk if it exceeds 16 hours?
There is no fixed concept of the so-called shelf life of boiled water, and the 16 hours that people often say is mainly from the perspective of food safety, after 16 hours of storage in the indoor environment, new bacteria may appear, so that the water is polluted to varying degrees.
However, if you can make sure that the boiled water storage container is well sealed, it is no problem to drink it after more than 16 hours. However, in order to ensure the safety and hygiene of drinking water, it is not recommended to leave boiling water for too long, and it is recommended to choose boiled water for a short period of time to drink.
Summary:
In order to maintain our kidney health, it is recommended that we take an appropriate amount of water in our daily life, and avoid drinking a large amount of water in a short period of time and drinking strong tea for a long time. Especially for patients with chronic kidney disease, you can consult a professional doctor about healthy drinking methods, please adjust the water consumption according to your own situation.
