6 enemies that silently 'kill the kidneys' in the cold season, Vietnamese people need to be wary of the 3rd one

The kidney is one of the important organs of the body. If the kidney function is healthy, it helps the body to regulate and adapt to changes in temperature in the cold season. Otherwise, it will cause an imbalance in the body's metabolism, causing illness and fatigue. Below are some factors that cause kidney damage that health and nutrition experts always warn about:

1. Environmental pollution

Environmental pollution.

With the development of industry, the problem of air pollution is becoming more and more serious and is posing serious danger to people's health.

The areas with the highest levels of air pollution are the Eastern Mediterranean and Southeast Asia. According to WHO guidelines, Hanoi has up to 91% of days with PM2.5 dust concentrations exceeding standards. PM2.5 dust is dust particles smaller than 2.5 µm in size, about 1/30 of a human hair. This type of dust is formed from substances such as Carbon, Sulfur, Nitrogen and other metal compounds, suspended in the air. PM2.5 dust has the ability to penetrate deep into the lungs and go directly into the blood, potentially causing a series of cancers and respiratory diseases.

Research shows that there is a relationship between long-term exposure to PM2.5 and the risk of membranous nephritis. Therefore, on days of dense smog, people should limit their time outdoors. If it is really necessary to go out, be sure to prepare yourself a thick mask.

2. Cold temperatures lead to increased blood pressure

Many people find that blood pressure easily gets out of control during the winter, this is because the lower winter temperatures stimulate vasoconstriction and higher blood pressure.

Studies have shown that blood pressure in winter is 6-12mmHg higher than in summer and the risk of cardiovascular and cerebrovascular diseases is twice as high in summer. Excessive blood pressure can also damage kidney function. To prevent this from happening, the first step is to promptly detect abnormal blood pressure and adjust medication as directed by your doctor.

In addition, people with high blood pressure should avoid salt in their daily diet. If you can control your salt intake to less than 3g per day, your blood pressure will be under control.

3. Hot pot

Hot pot.

Eating hot pot regularly increases the risk of gout, high blood pressure, if you eat too much it will directly affect kidney function. If you really want to eat hot pot, season the hot pot broth not too salty, add more tomatoes, vegetables, limit meat intake and hot pot broth.

4. Cold

When it's cold, the large temperature difference between indoors and outdoors, and poor air circulation, are the causes of colds.

For people with weak kidneys, each cold can cause the disease to recur or even worsen. Once a cold occurs, the patient should seek medical advice promptly and proactively inform the doctor of the history of kidney disease. Any prolonged treatment, or combination of cold medicines, can lead to more serious kidney damage.

The best way to deal with a cold is to take preventive measures such as regular exercise, a scientific diet, and building strong resistance to support the kidneys.

5. Eat a lot, exercise little

Eat a lot, exercise little.

Fat is a great weapon against the cold, but it is also one of the kidney killers. Too much fat can cause inflammation in the body, affecting kidney health. Data shows that obese people have a 23% higher risk of kidney disease than normal people.

Therefore, if you want to combat the harmful effects of fat on your kidneys, control your food intake and exercise regularly.

6. Supplements

According to many people, winter is a good time to supplement nutrition. However, when the kidneys are damaged, you need to be very careful not to accidentally allow the nutrients in supplements to increase the burden on the kidneys, leading to acute kidney failure.

What to do to protect kidneys in winter?

- Monitor blood pressure daily and adjust blood pressure medication as directed by your doctor;

- Wear a mask when going out, stay away from the dangers of dust and cold bacteria;

- Limit smoking and drinking alcohol;

- Low salt diet, avoid pickled foods and many spices.
