Smartphone use linked to neck strain, vision loss and skin problems

Scientific research indicates that prolonged use of phones and other digital devices can cause a forward‑head posture that loads the neck with up to 27 kg, a condition known as “tech neck”. Over time this may damage cervical discs, weaken joints and muscles, and even reduce lung capacity. Experts recommend raising screens to eye level, keeping a distance roughly equal to an outstretched arm, and taking 20‑minute breaks after every 30 minutes of screen time, along with targeted neck‑strengthening exercises.

Skin irritation can arise from constantly wearing smartwatches, where a dark, moist environment promotes fungal growth and may trigger eczema or allergic reactions to materials such as nickel, rubber, latex or acrylates. Simple hygiene—removing the watch regularly, cleaning the skin and using protective creams—helps prevent these problems.

Regarding vision, a study led by Professor Donald Mati (Ohio State University) found no direct link between near‑work on devices and myopia, though overall myopia rates continue to rise. Outdoor exposure appears protective, possibly through dopamine release in the retina. While some dermatologists suggest a theoretical link between tech neck posture and neck wrinkles, solid scientific evidence is lacking.
