Bedtime Reels, Shorts linked to poorer sleep, expert says

Watching short-form videos such as Reels and Shorts before bed may disrupt circadian rhythms, reduce sleep quality and increase anxiety, according to Maria Matveeva, a Doctor of Medical Sciences and associate professor at Novosibirsk State University.

Speaking to TASS on the sidelines of the Technoprom-2026 forum, Matveeva said blue light from screens can suppress melatonin production, making it harder to fall asleep and contributing to more superficial sleep.

She also said the constant switching of images in short-form videos can cause repeated stimulation of the nervous system, making it harder for the brain to enter a state conducive to sleep.

According to Matveeva, short-form video platforms can also contribute to addictive behaviour through algorithms based on variable reinforcement. She said the constant exposure to bright stimuli can overload the dopamine system, reducing self-control and increasing impulsivity.

As a result, she said, viewers may find it more difficult to relax and fall asleep.
