Rumor Refutation:Learn theTruth and Bust the Rumors

 Rumor 1 :The middle layer of the mask that cannot burn is the real mask

/✗:This is a wrong statement

The main material of masks includes polypropylene and others. According to data, polypropylene is a thermoplastic resin produced by the polymerization of propylene, and the material itself is flammable. However, relevant regulations state that "the materials used in masks should not be flammable, and the afterglow time should not exceed 5 seconds." Therefore, there is no requirement for masks to be "non-flammable."

Rumor 2 :If the waste in the blood vessels is not cleared, it can form blood clots and block the blood vessels.

/✗:This is a wrong statement

There are no so-called "trash" or "toxins" in the blood vessels; rather, there are only metabolic waste products. These waste products are natural byproducts of cellular metabolism. Normally, they are transported through the bloodstream to specific organs and ultimately excreted from the body without causing any harm.

For example, urea, guanidine compounds, phenols, and other products resulting from protein metabolism are excreted through the kidneys. Drinking adequate water and increasing urine output can help accelerate the removal of metabolic waste products.

Moreover, no health supplements can eliminate these waste products from the body.

Rumor 3 :Eating uncooked tomatoes can cause poisoning.

/✗:This statement is not entirely correct

Indeed, unripe green tomatoes contain a large amount of solanine, a weakly alkaline glycoside composed of glucose residues and solanidine. Solanine has a strong irritant and corrosive effect on the gastrointestinal mucosa and can paralyze the central nervous system, especially the respiratory and motor centers, potentially leading to death in severe cases. Therefore, unripe green tomatoes should not be consumed raw.

Rumor Refutation:Can an ordinary mask turned into an N95 mask by tying a knot?

  1.Wearing a medical mask with knots tied improves its sealing performance Following the method demonstrated in the video, the sealing performance of a common surgical mask can indeed be improved, preventing viruses from reaching the respiratory tract through gaps on both sides. Before conducting science popularization and promotion, the US CDC publicly released relevant experimental reports around February 2021. The report indicated that tying knots and then wearing the mask can enhance filtration efficiency. 2.Knots don't turn it into an N95; there are significant differences in all aspects. The differences between the medical surgical masks we usually use and N95 masks manifest in many ways: In terms of filtration efficiency: N95 masks are one of the nine particulate respirators certified by the National Institute for Occupational Safety and Health (NIOSH). The "N" stands for "not resistant to oil," and "95" indicates that the filtration effic...

Rumor Refutation: Pay Attention to Dental Health NO.1

  Rumor 1: Orthodontic treatment should be done as early as possible, and the earlier the correction, the better the result. ✔/✗: Partially correct, partially incorrect. Orthodontic treatment should indeed be initiated early, but not necessarily as soon as possible. The period from 7 to 12 years old is a crucial stage for early intervention, during which the growth potential of teeth and jaws can be fully utilized to correct dental and jaw malformations. Therefore, all children should undergo an initial consultation with an orthodontist at age 7 to check for dental anomalies such as impacted teeth, supernumerary teeth, and congenitally missing teeth. For certain specific malformations, such as skeletal Class III malocclusion (anterior crossbite) and mesio-inclined lingual occlusion, orthodontic treatment may begin as early as age 5. However, in clinical practice, it is often observed that some 2-year-olds undergo orthodontic treatment, which falls into the category...

Rumor Refutation: Pay Attention to Dental Health NO.2

  Rumor 1: There are many complications associated with orthodontic treatment, so it should be avoided if possible. ✔/✗: Incorrect statement. In reality, the sequelae associated with orthodontic treatment are far fewer than people often perceive. When appropriate appliances and forces are utilized for correction, and patients comply well with treatment, these supposed sequelae can be completely avoided. In the case of adult orthodontic treatment, there are indeed some special considerations. For instance, adult patients may already have periodontal disease or gingival recession, and in cases of malalignment, there may be insufficient bony support between teeth, which can lead to the emergence of "black triangle" spaces after correction. This phenomenon is relatively common in adult orthodontic treatment, but it is not a direct consequence of the treatment itself; rather, it is a natural occurrence during the improvement of tooth alignment. To minimize the oc...
