To be precise: proper cycling and walking will not hurt your knees.

Walking and biking are neither exercises that put a lot of pressure on the knees.chopper bike motorcycle Under the standard weight, the pressure on the knees caused by the correct operation is 0.5-1 times of the body weight. Walking, long-distance walking, etc. are likely to cause damage to the knee. Other jumping actions such as basketball, volleyball, badminton, tennis, rope skipping, running, and frog jumping are more likely to damage the knee.

The aerobic exercise that does not hurt your knees

The aerobic exercise capacity for a knee joint with less functional impairment usually includes swimming or rowing.

Swimming can be said to have the least impact on the knee joints of all sports, because each joint of the human body basically does not bear weight in the water. In addition, the buoyancy of water can help people move their joints while losing weight. But swimming is a difficult technique to learn. If the posture is not correct, it can also cause damage to the knee joint.

However, the rowing machine does not carry any weight when sitting and sliding, or part of the knee joint is compressed, and the angle of flexion and extension of some joints is also within a safe range. But rowing is only common in modern gyms and studios, and few people use it.

There is also an elliptical machine. When the elliptical machine uses the trajectory of the elliptical machine to move the legs, the trajectory is fixed, and the pedaling frequency is more appropriate, so the damage to the knee joint is less.

You can brush your teeth and comb your hair to protect the clean and healthy teeth and scalp

There is a traditional saying: “During confinement, 坐月禁忌you cannot brush your teeth or comb your hair, otherwise your teeth will loosen prematurely and your scalp will be prone to pain.” In fact, you should brush your teeth well during the month, keep your teeth clean, and occasionally comb your teeth to protect them. skin. According to Chinese tradition, teeth are “bone in bone”, and the main bone of teeth, coupled with stomach pain, has the closest relationship with teeth, teeth and stomach. When the spleen is weak, toothache is prone to problems. After childbirth, only the spleen and kidney qi is weak, so care should be taken to keep the teeth healthy.

During confinement, in order to supplement calories and nutrition, mothers consume more high-protein and carbohydrate foods than usual, which can easily cause tooth decay and bad breath. At this time, they should pay special attention to tooth cleaning. Not brushing teeth is harmful to dental health. It is recommended that as long as physical strength permits , You can start brushing your teeth after delivery, just follow the usual cleaning methods.

Soda, many people drink it wrong

  Soda water is highly sought after because it claims “can change acidic physique, neutralize stomach acid, relieve gout” and other effects, and some people even use it as daily drinking water. But it needs to be reminded that although soda water can help health to some extent, the effect is limited, and it is not suitable for everyone.

  There are two main types of sodas currently on the market: one is natural soda, which is a weakly alkaline water containing a variety of minerals, trace elements and sodium bicarbonate; the other is soda, which is artificially synthesized The soda water is made by pressing carbon dioxide into purified water and adding sweeteners and spices.

  From a medical point of view, the weak alkalinity of soda water does have certain health benefits. It can alkalize urine, promote the dissolution of uric acid, and relieve gout to a certain extent. It can also neutralize stomach acid and help relieve symptoms of stomach acid. Many people abroad have the habit of drinking soda after exercise, which can promote the neutralization of lactic acid and alkaline water into inorganic salts, which are excreted with sweat and urine to relieve fatigue, backaches and other discomforts. However, there is no scientific basis to prove that soda water can change the acid-base physique. The acid-base physique itself is a pseudo-concept. No matter what food is eaten, it will become acidic in the stomach. Foods with different pH levels cannot change the pH of body fluids.

  What needs to be reminded is that the above mentioned are all the effects of natural soda water. The “soda drink” containing carbon dioxide and weakly alkaline soda water are completely two concepts. Because the mineral elements in natural soda water are in an ionic state, they are easier for the human body to absorb; while artificial soda water does not have this point, it contains a large number of additives, which may also cause blood sugar and blood lipids to increase. When buying soda water, you should choose more natural soda water. The identification method is very simple, just see if there is “sodium bicarbonate” in the ingredient list.

  In addition, soda water is not suitable for everyone, you should pay attention to the following 3 points before drinking:

  First, soda water contains sodium bicarbonate. Excessive intake of sodium ions, an important ingredient in it, is harmful to the health of patients with high blood pressure, hyperlipidemia, and chronic kidney disease. people with such diseases should try not to drink it.

  Second, patients with gastritis who have too little gastric acid secretion should drink less, or even not drink, to avoid stomach discomfort or aggravation of gastric disease.

  Third, healthy people should also not drink large amounts of soda for a long time, otherwise it will easily cause excessive sodium in the diet, which is harmful to cardiovascular health.

  Finally, I emphasized that it is okay to drink it occasionally at the level of natural soda. For example, for healthy people, after exercise, when the stomach is upset, you can drink about 100ml, but it must not be excessive, let alone replace boiled water and become daily drinking water. ▲
