In 2026, most of us are practically glued to our smartphones, but when it is finally time to sleep—perchance to dream—it is best to physically part with your rectangular digital assistant.
While keeping your device on a bedside table is common practice, tucking it directly under your pillow poses a very real safety risk.
Modern smartphones are powered by lithium-ion batteries that require adequate airflow to dissipate heat. When trapped in an enclosed, insulated space like under a pillow or blanket, that excess heat has nowhere to go, transforming your device into a genuine fire hazard. As the battery overheats, it can swell, rupture, or even catch fire while you sleep.
This danger escalates dramatically if you charge the device overnight, as the charging process naturally generates additional thermal output.
If you prefer keeping your phone nearby, place it flat on a hard surface like a nightstand instead. Furthermore, while health authorities maintain that non-ionizing cell phone RF radiation has not been proven harmful to humans, minimising direct body contact remains a sensible precaution.
Switching your phone to Flight Mode overnight—assuming you do not need to receive emergency calls—reduces ambient signal transmission and offers the added bonus of preserving your battery’s long-term health.
The ideal strategy is keeping your phone entirely out of arm’s reach. Positioning it across the room introduces a deliberate physical barrier, preventing mindless late-night checking during your usual sleeping hours.
Of course, poor sleep is frequently driven by late-night scrolling habits. To combat this, take full advantage of the built-in Digital Wellbeing (Android) and Screen Time (iOS) features. Establishing strict daily app limits sets firm boundaries for healthy tech usage, helping you wind down without distraction.
