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

• 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.
