"As soon as people get older, they are really afraid of the cold. I remember that back then, when it snowed in the middle of winter, I was only wearing a cotton jacket!"
Uncle Li and his neighbor Mr. Zhao were chatting in the community, feeling that autumn has begun recently, and the temperature has dropped suddenly. Uncle Li said, "I don't know what happened this year. As autumn comes, my hands and feet start to get cold and I tossed and turned to sleep at night." Uncle Zhao found a video from somewhere and started to "popularize science" for Uncle Li. The video mentioned that if your hands and feet become cold, unable to sleep, or even dizzy when it comes to autumn and winter, it means that your kidneys are not good and you should nourish your kidneys.
Uncle Li is a little confused about this. He has always been in good condition, but recently the situation mentioned in the video has indeed occurred. Is it really because his kidneys are not good?
Is the cold hands and feet related to the kidneys in autumn and winter? Today, 1 Medicine.com will reveal the secret to you.
Is the kidney good? Look at these 4 manifestations
As the saying goes, the kidney is the "engine of the human body", and the various life activities of the human body cannot be separated from the kidney.
The kidney is the place where urine is generated. The waste produced by the human body during metabolism will be filtered through the glomerulus and renal tubules in the kidneys and then excreted from the body. The kidneys can regulate the environment and acidity and alkalinity in the body, so that they always maintain a relatively balanced state. At the same time, the kidneys are also the main production place for hormones such as renin , prostaglandin and erythropoietin. These endocrine hormones have important physiological effects on various organs of the body.
Once there is a problem with the kidney, the human body often has these 4 symptoms:
. Body edema
Eedema is a characteristic manifestation of kidney disease. If you wake up in the morning and experience swelling in the eyelids, hands and feet, etc., this is actually a sign of poor kidney function.
. Foaming urine
Generally speaking, the urine of normal people is clear, slightly yellow, without foam or has a small amount of foam, but when the content of protein and sugar in the urine becomes high, foam will appear.
Of course, if there is an occasional foam in the urine, it may not be proteinuria and diabetes, but may be caused by inappropriate diet. But if foamy urine still often occurs under normal diet, 1 Yao.com recommends that you go to the hospital for routine urine tests.
. Change of urine volume
Normal adults have about 1000~2000ml per day, and the average daily volume is about 1500 ml. Under normal drinking water, whether the amount of urine increases or decreases, it may be caused by kidney problems. Especially at nocturnal polyuria is often a disease signal sent by the kidneys and should be taken seriously.
. A pale face, afraid of cold
Healthy kidneys can produce a substance called erythropoietin, referred to as "erythropoietin". However, when renal function is abnormal, it will cause the concentration of erythropoietin to decrease, and erythropoietin cannot proliferate and divide normally, which will cause anemia in the human body. People with anemia generally show that they have sallow complexion , pale conjunctiva of the eyes, and pale and dull lips. Patients with long-term renal anemia of will also experience chills, fatigue, drowsiness, appetite deficiency, muscle weakness, decreased mobility, difficulty in concentration, memory and intelligence.
Combined with the above 4 manifestations, 1 Medicine.com can determine that Mr. Li's hands and feet are cold and difficult to fall asleep, which actually has nothing to do with poor kidneys.
Why are you cold and cold?
Although many middle-aged and elderly people like Mr. Li are usually in good health, they will get cold hands and feet and cannot sleep well when the season changes. 1 Medicine.com combined with relevant research found that the following four main causes of this health problem.
. Exercise too little
Exercise can not only generate calories, but also speed up blood circulation and promote metabolism. But the elderly often cannot exercise due to some reasons such as poor legs and feet. In the long run, blood circulation will slow down and you will easily feel afraid of cold.
2. The clothes are too tight
In winter, some middle-aged and elderly people may wear several pairs of autumn pants because they are afraid of the cold. However, wearing too many tight clothing can easily lead to poor blood circulation at the end of the body, such as hands and feet, resulting in symptoms such as cold hands and feet.
. Eat only vegetarian
Some elderly people have the habit of eating vegetarian food for a long time. Although fruits and vegetables contain a lot of vitamins and dietary fiber, their calories are particularly low and cannot provide the human body with the sufficient energy it needs.
Long-term failure to eat meat can easily lead to insufficient calories in the human body, and people will become afraid of cold and cold, and their hands and feet will be cold.
4. Qi deficiency and blood deficiency
Most women are more likely to have cold hands and feet than men. This is because women will experience physiological conditions such as menstruation and pregnancy, which can easily cause qi and blood loss. People with insufficient qi and blood are also very likely to have cold hands and feet.
Do these 6 points well, and the whole autumn and winter will be warm
In fact, the cold hands and feet in autumn and winter can be improved through some daily habits. 1 Yao.com has compiled the following 6 methods for your reference.
1. Frequently rub your hands and feet
Frequently rub your hands and feet can improve the microcirculation status of the terminal blood vessels. When rubbing the soles of your feet, use your palms to rub them quickly until they feel hot. When rubbing the palms, clench one hand and rub the palm of the other hand until the palm is slightly hot, then change the other hand, and alternate between the two hands.
2. Exercise more
Middle-aged and elderly people can usually choose some relaxed and smooth exercises with little activity, such as strodes, practicing Tai Chi, etc. The exercise frequency is 3 to 5 times a week, and half an hour each time is appropriate.
3. Bathing in the sun
In autumn and winter, people like to go out and basking in the sun. Bathing in the sun not only promotes the absorption of calcium, but also makes the body warm and comfortable in the cold season.
It is best for middle-aged and elderly people to bask in the sun from 9:00 to 10:00 am. During this period, the infrared accounts for the majority, and the ultraviolet rays are low, which can warm the body to promote blood circulation.
4. Ensure adequate sleep
Experts point out that in autumn and winter health care must first ensure adequate sleep. You should "lie down early and get up late, and wait for the sun to shine." In winter, the sun rises late. Going to bed early can nourish the body's yang energy, and getting up late can avoid the invasion of cold.
5. Keep soaking your feet
It is best to soak your feet in hot water before going to bed in autumn and winter. Generally, use hot water at about 40 degrees and soak for about 20 minutes. After soaking your feet, wipe them dry with a towel immediately and put on socks in time to keep them warm. For some elderly people who are afraid of the cold, they can wear warm cotton socks to sleep to avoid cold feet.
6. Wear loose clothes
Regularly wearing leggings and tights will cause poor blood circulation in the lower limbs, slowing down blood circulation on the limbs and skin surfaces. In addition, the elderly feel dull, which may also cause frostbite in severe cases. It is recommended that the elderly choose light and loose clothes in autumn and winter.
