Applying sesame oil or alcohol can help ticks fall off on their own, applying toothpaste or soapy water after being bitten by mosquitoes can cure it, wearing glasses can cause myopia to increase faster, some products can make the eyeball roll back and eliminate myopia... With the change of seasons and the arrival of summer vacation, some "seasonal" rumors have resurfaced. Applying sesame oil or alcohol to stimulate ticks can accelerate their saliva secretion, increasing the risk of infection by tick borne pathogens. ”At a press conference held by the National Health Commission on June 5th, Liu Qiyong, a researcher at the Chinese Center for Disease Control and Prevention, explained that ticks can contract their bodies after being stimulated, and even cause their mouthparts to break and remain in the skin, causing local inflammation, infections, and so on. As the weather becomes hot and humid, mosquitoes and insects increase in nature, and health problems in summer present new characteristics. People may have some misconceptions when dealing with them. Liu Qiyong said that there is no scientific evidence to support the use of toothpaste or soapy water to prevent infectious diseases after being bitten by mosquitoes. Toothpaste and soapy water can only alleviate the itching symptoms after biting, but cannot kill the pathogens such as dengue virus and malaria parasite carried by it, so they cannot prevent infection. If you experience discomfort such as fever after being bitten by mosquitoes, seek medical attention promptly. People often ask: Do mosquitoes prefer a certain blood type, such as O blood? At present, scientific research has confirmed that there is no clear correlation between blood type and mosquito blood sucking preference. ”Liu Qiyong introduced that mosquitoes rely more on actual physiological characteristics and environmental factors when choosing bite targets. The carbon dioxide exhaled by the human body is the core signal for mosquito positioning, and people with high metabolism, such as pregnant women and those who exercise, are more susceptible to mosquito bites. Every summer vacation, there is a 'mirror picking craze', and rumors often arise in the hot topics that people pay attention to. Some products on the market, such as "myopia prevention and control stickers" and "eye protection devices," falsely promote themselves in order to increase sales, claiming that they can make the eye axis retract and eliminate myopia. Regarding this, Wei Wenbin, chief physician of Beijing Tongren Hospital, introduced that once myopia occurs, it is irreversible. Some product promotions lack high-quality evidence verification, and long-term effectiveness and safety cannot be guaranteed. Long term use of some products may also cause irreversible damage to the retina. The mainstream laser myopia surgery, such as full femtosecond and half femtosecond laser correction, has a relatively mature technological development and high safety. ”Wei Wenbin said that a large amount of clinical data and long-term follow-up results show that as long as strict preoperative evaluation is conducted and unsuitable populations are excluded, postoperative visual quality is good. Regarding the issue of adolescent eye use that parents are concerned about, Wei Wenbin explained that some parents believe that their children only need to wear glasses while studying, which is often unreasonable. Unless otherwise advised by an ophthalmologist, adolescents with simple myopia should wear glasses throughout the day. Wearing appropriate glasses is not only for "seeing clearly", but also to keep the eye's accommodation in a relaxed state. In addition, stable and clear visual input can ensure the normal development of the visual center in children's brains. There is currently no conclusive evidence to prove that consuming certain foods can significantly improve vision or delay the development of myopia. ”Wei Wenbin said that some beneficial nutrients for the eyes mainly maintain the normal function of eye tissues, and excessive supplementation of such substances cannot directly prevent or reverse eye diseases such as cataracts and macular degeneration. In general, it is not recommended to supplement vitamin supplements or eye health products for individuals without obvious nutritional deficiencies or a history of eye diseases. Blindly taking high-dose vitamin A in children may cause side effects such as liver toxicity. There are various rumors related to health, and it is important to master the skills of identifying them. ”Hu Qiangqiang, spokesperson for the National Health Commission and deputy director of the Propaganda Department, said that some rumors use a lot of provocative and extreme language to render emotions, such as using phrases like "urgent", "quick forward", "life-saving", "shocking", "forward for family members" to induce clicks and shares. Health information with these characteristics is mostly rumors. When encountering health information that cannot be distinguished from true or false, it can be searched and queried on the official website's "Refutation Platform". (New Society)
