Insight! The truth and falsehood of nine classic old sayings

When we advise others, we often say, "If you don't listen to the advice of the elderly, you will suffer losses in the future." This means that we must listen more to the advice of the elderly. But are all the things they say correct? The following editor will test nine classic sayings of the elderly for you. Let's find out quickly.

The elderly use their own experiences to teach the younger generations how to do things, and some of their advice is indeed very useful, but some of the elderly’s words have no scientific basis and are even wrong.

Technology has developed, and the old saying has become wrong.

With the development of science and technology, we are increasingly able to see the essence through phenomena. As for many health maxims summed up by the ancients due to limited conditions, we can now judge the right and wrong. For example, "You can't take a bath during menstruation." This is because in the past people could only take a sitting bath, during which time pathogenic microorganisms could easily enter the body. The menstrual period is when the female reproductive system's immunity is relatively weak, so reproductive system infections are more likely to occur. In modern life, we have showers. So, are you still going to cover yourself up for 6 days?

Nine classic old sayings to test their authenticity

1. Eat radish in winter and ginger in summer, and you won’t need a doctor’s prescription

right!

Refresh suggestion: Still in line with reality and can be retained in its entirety.

This sentence is very consistent with the principle of health preservation. From the perspective of natural laws, radishes are seasonal vegetables in winter, and eating more radishes is in accordance with the laws of nature. Summer is the season for harvesting ginger, which has antibacterial and bactericidal effects and can prevent intestinal infectious diseases.

On the other hand, Chinese medicine believes that the weather in winter is very dry, but radish has the effect of moistening the lungs and promoting salivation. Summer is the best season to maintain the body's yang energy, and ginger has a spicy and hot nature. People often eat raw and cold food in summer, so ginger can nourish the yang energy and warm the stomach.

2. If you want your child to be safe, keep him/her three parts hungry and cold

Half right and half wrong!

Refresh suggestion: It has certain reference value, but we still need to raise children scientifically and keep a sense of proportion.

Children's digestive function has not yet fully developed, and eating too much will cause digestive dysfunction, so it is best to eat only 70% to 80% full. But the child cannot be too hungry, otherwise insufficient nutrition will affect his growth. Wearing a little less clothing can stimulate immunity, but there should be a limit to the cold. Otherwise, excessive cold will reduce immunity.

3. It is better to store it in the pot than to have a full stomach

right!

Refresh suggestion: Although it is an old saying, it is very practical in reality and should be kept in mind in daily life.

Rather than malnutrition, modern urban residents face more problems such as overnutrition and overeating. If you eat too much, on the one hand it will cause the gastrointestinal motility to decrease and the digestive ability to reduce. On the other hand, it will cause the energy supply to exceed the body's needs and cause obesity and other problems. So whether you are at home or outside, don't eat too much just because there is too much food. When you are already full, don't force yourself to eat more in order to avoid wasting food.

4. A sip of soup before meals, no need to go to the pharmacy

Half right and half wrong!

Refresh suggestions: You can refer to them, but you don’t have to follow them strictly.

Drinking a small amount of soup before meals can stimulate the secretion of gastric juice and create an environment in the stomach that is conducive to digestion. When eating harder foods, it will not cause harm to the stomach and is beneficial to health. However, if you drink too much soup before a meal, it will dilute the gastric juice, which is not conducive to the digestion of protein and fat, leading to indigestion. So, be careful about the amount of soup you drink before meals.

5. Don’t pull out your gray hair. If you pull out one, ten will grow back.

wrong!

Refresh suggestion: It has been verified to be unreasonable, please delete it.

A white hair will not grow back one or more just because you pull one out. The hair follicles surrounding the hair are actually formed when the embryo is formed. Although one hair does not necessarily grow for each follicle, if the hair in a follicle is pulled out, the same number of hair will still grow. Therefore, the saying "pull out one and ten will grow" is not true.

6. Do not sit on stone in winter and wood in summer

right!

Refresh suggestions: Still useful, please keep them in mind

Sitting on stones in winter may allow cold air to enter the human body and damage the yang energy. The weather is humid in summer, and the seemingly dry wooden chairs actually contain quite a lot of moisture. If you often sit on wooden chairs placed outdoors, it is possible that moisture will invade your body through the genitals and induce disease.

7. Staying in the sun every day is better than taking medicine

Half right and half wrong!

Refresh suggestions: decide whether to listen based on the actual situation.

This statement is somewhat biased. On the one hand, sunbathing can kill mites on the surface of clothes. On the other hand, after the skin is stimulated by ultraviolet rays, melanin will be produced, which is beneficial to the conversion of vitamin D and thus promotes calcium absorption. However, in today's cities with strong ultraviolet rays, serious light pollution and high incidence of smog, you must choose the right time to sunbathe. When the sunlight is strong, excessive exposure to the sun may cause skin cancer.

8. Walk 100 steps after a meal and live to 99

wrong!

Refresh suggestion: There are health risks and adjustments are needed.

If you take a walk immediately after a meal, since you have just finished your meal, your blood will be mainly distributed in the digestive system. Exercise will cause blood to flow to the limbs, reducing the blood flow in the digestive system and reducing the secretion of digestive juice, which is not conducive to food digestion and nutrient absorption. On the other hand, if you eat too much and walk immediately after the meal, it is easy for the ligaments that suspend the stomach to be stretched, and there is a risk of gastroptosis. Therefore, it is best to rest for a while after a meal before leaving.

9. Keep warm in spring and cool in autumn to avoid diseases

right!

Refresh suggestion: Make slight adjustments based on your personal living environment.

"Spring covering" means that when winter turns to spring, you should not take off your cotton clothes too early to prevent your body from getting cold and causing your resistance to drop, which allows germs to attack the body and cause various respiratory diseases and infectious diseases in winter and spring. "Autumn freeze" means that after the arrival of autumn, do not add more clothes as soon as the temperature drops slightly. Instead, you should freeze appropriately and exercise to improve your adaptability to low temperatures.

But everything has a limit. If you still cover yourself too much or wear too thin clothes in late spring and late autumn, this kind of "covering up in spring and keeping warm in autumn" is excessive.
