Rumor Refutation：Can Placing a Mobile Phone on the Bedside While Sleeping Really Cause Cancer?

 The radiation emitted by mobile phones is electromagnetic radiation, which is a type of non-ionizing radiation. It does not cause cancer.

Non-ionizing radiation is a type of radiation with relatively low intensity, unable to attract atoms and electrons. Ultraviolet rays, infrared rays, light, as well as electromagnetic waves and microwaves generated by household appliances, all fall into the category of non-ionizing radiation.

On the other hand, ionizing radiation is a type of radiation with high intensity, capable of attracting atoms and electrons. The radiation produced by radioactive elements, nuclear reactors, and nuclear weapons belongs to ionizing radiation.

Generally speaking, exposure to ionizing radiation greatly increases the risk of cancer and other diseases. Depending on the dose and duration, it can even cause death in the short term.

Compared to the radiation issue of mobile phones, other health problems caused by their use deserve more attention:

  • Cervical spine injury

Prolonged looking down at mobile phones is a significant reason for the younger generation to suffer from cervical spondylosis. Extended periods of looking down increase the pressure on the cervical spine, leading to changes in cervical lordosis, and potentially causing cervical disc herniation and cervical instability.

  • Lumbar spine injury

Many people like to play with their phones in a semi-reclined position, which can harm the lumbar spine. In a semi-reclined position, the lumbar spine lacks sufficient support, altering its natural curvature and increasing the force on the intervertebral discs, potentially inducing lumbar disc herniation over time.

  • Neck wrinkles

When looking down at a mobile phone, the neck bears greater pressure than usual. The muscles in the neck grow vertically and are prone to sagging. Additionally, maintaining a hunched position compresses the neck, shortening its muscles and accelerating the aging of epidermal cells, thereby deepening wrinkles on the neck.

  • Skin allergies

Some people may develop contact dermatitis from exposure to mobile phones. This is because some individuals may be allergic to metals, rubber, and other materials often found on the surfaces of many mobile phones, making them potential allergens.

Moreover, exposure to mobile phones irritates the skin. As call duration increases, the temperature of the mobile phone rises, potentially exacerbating skin problems such as acne and pimples.

  • Eye damage

For children, prolonged close-up use of mobile phones keeps their eyes in a tense and strained state, without adequate rest, which can easily lead to myopia. For adults, staring at screens for long periods reduces blinking by one-third, causing more tear evaporation on the ocular surface and leading to a lack of lubrication.

Tear evaporation is one of the main causes of dry eye syndrome, which can ultimately result in permanent eye damage.

  • Triggering tenosynovitis

Although tenosynovitis is generally more prevalent in middle-aged and elderly individuals, prolonged mobile phone use can also cause tenosynovitis among younger people, with symptoms including soreness and spasms in the fingers, wrists, and forearms.

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: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.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...
