Two UK outlets report warnings from experts about a common late-night habit: charging a phone while it is in bed or near bedding before sleep. The Mirror and Daily Express both describe the practice as potentially dangerous, particularly when temperatures are high. Both accounts suggest that the risk increases during a heatwave, when phones and chargers may generate additional heat and where items such as blankets, pillows, or mattresses can trap warmth. The reports frame the issue as a broader safety concern rather than a specific incident, urging people to avoid charging phones in places where heat cannot dissipate. They also emphasize that many people routinely charge devices overnight, implying that the advice targets widespread behavior. Neither source provides details of a specific fire or accident, but both cite expert concern that sleeping areas are not appropriate locations for charging equipment. The overall message is to change charging habits to reduce potential overheating and fire risk during periods of extreme heat.
