Will OK lenses wear the cornea?

Rumor content: The eyeball is soft and the OK lens is hard. It will wear the eyeball and cause the cornea to become thin, so it cannot be worn regularly.

truth interpretation: OK lens, also called orthokeratology lens , is a non-surgical refractive correction method. There is basically no relative movement between the OK lens and the eyeball. The material is also very safe and will not wear the cornea when used correctly. It should be noted that not everyone with myopia is suitable for OK lenses and should be judged and fitted by doctors from professional institutions. The effect of orthokeratology lenses is reversible. If you stop wearing them for two weeks, the corneal shape will basically recover. In addition, the cleaning and care of OK lenses must be standardized to prevent lens contamination from causing keratitis . (Source: Toutiao refuting rumors)

Can soda water adjust the body’s acid-base balance?

Rumor content: Drinking more soda water is good for the body and can regulate the body's acid-base balance.

Interpretation of the truth: None of the claims about regulating the acid-base balance of the human body through diet is scientific. The internal environment of a healthy human body can automatically maintain a suitable pH range, providing a stable environment for physiological activities in the body. For example, the pH value of blood will always be constant between 7.35 and 7.45, and will not change due to drinking soda. Drastic changes in blood pH are often due to major diseases, such as cancer . Therefore, it is nonsense to say that drinking soda water changes the acid-base constitution. Instead of worrying about acid-base, it is better to pay attention to food diversity and make your nutritional intake more balanced and comprehensive. (Source: Scientific Rumor Refutation)

If you suffer from gout, you cannot eat tofu, meat and eggs?

Rumor content: People with gout cannot eat tofu, meat, and eggs, otherwise they will get sick.

Truth interpretation: This is a common misunderstanding. During the production of soy products, most of the purine has been lost, so eating soy products does not increase the risk of gout attacks. Considering that blood uric acid may temporarily increase after a meal, it is generally recommended to control the intake of soy products, especially in the acute stage of gout, and follow the doctor's advice. Compared with high-purine foods such as animal offal and crustacean seafood, meat and eggs do not have a great impact on blood uric acid after consumption. These foods are rich in protein, fat-soluble vitamins, and other essential nutrients for the human body. Long-term lack of intake will cause nutritional imbalance, which will in turn reduce the body's ability to metabolize purine and increase blood uric acid. (Source: Toutiao refutes rumors)

Is the longer the stretch better after exercise?

Myth content: Stretching after exercise helps relax muscles, and the longer the stretching time, the better.

Truth interpretation: If the stretching time is too long, not only will the effect not be better, but it will also bring the risk of over-stretching. Studies have shown that stretching for more than half an hour has no obvious benefit compared to stretching for 10 minutes. On the contrary, it will increase the risk of overstretching joints and ligaments due to stretching for too long. Usually after exercise, each stretching action is done for 30 seconds to 60 seconds, 1-2 times, and the total stretching time for various actions is about 10 minutes.

Can making oleander tea enhance physical fitness?

Rumor content: Oleander is poisonous, but taking it can fight poison with poison and strengthen your body.

Interpretation of the truth: This is just a folk remedy. Although oleander has medicinal value, it cannot be taken privately because the wrong dosage or wrong preparation method may lead to poisoning. Recently, a girl in Zhengzhou took a photo with an oleander in her mouth. The flower juice was absorbed into the body through the mucous membrane of her lips, causing poisoning. If you accidentally eat oleander, you must seek medical treatment as soon as possible and seek professional help. If you have young children or pets at home, you should not keep oleander to avoid poisoning. (Source: Toutiao refuting rumors)

There are worms in bayberries. Is eating them harmful to the body?

Rumor content: A video posted online showed that small insects crawled out of bayberries, proving that bayberries are dirty and eating them is harmful to the body.

Interpretation of the truth: The worms in bayberry are Drosophila larvae. They feed on fruits and vegetables and are not likely to carry germs and are safe to eat. It is difficult to avoid the infestation of bayberry insects, and there is no way to tell them apart. It is recommended to soak bayberries in salt water to repel fruit fly larvae and rinse them before eating. (Source: Tencent is true)
