Neurologist explains risks of smartphone use before bedtime

Prolonged smartphone reading with the head bent forward can increase strain on the neck, while scrolling through worrying news before bed can make falling asleep harder. Neurologist Anton Tikhonovsky of Olimp Clinic MARS discussed the risks on October 9.

Speaking to Gazeta.Ru, the doctor advised against resting a phone on the abdomen or knees because it encourages users to bend towards the screen. He suggested sitting or reclining with the back and neck supported at roughly 45–60 degrees, with the device on a stand or firm pillow about 30–40 centimetres from the face, near chest or chin level.

The claim that every additional 15 degrees doubles the load needs qualification. A study by Kenneth Hansraj published in 2014 calculated increasing loads as the head tilted forward, but not a doubling at each such step. The model describes mechanical loading and cannot by itself predict disease in an individual.

Tikhonovsky also warned that a comfortable posture does not remove the emotional stimulation created by a constant flow of information. He said doomscrolling can increase anxiety and make sleep harder. The US National Heart, Lung, and Blood Institute recommends quiet activities before bed and limiting bright light from screens.
