To this is added another danger that many people ignore: the risk of fire. Charging the phone while you sleep, especially if it is covered by the pillow or a sheet, can cause the device to overheat. There have been documented cases in which batteries have exploded or caught fire due to excess heat or the use of poor quality chargers. Although these incidents are rare, they occur, and it would be enough only once to cause tragedy.
The emotional and psychological impact also deserves attention. Before bed, many people stay by checking social media, news or messages. This seemingly harmless habit can generate anxiety, stress, or negative thoughts just the moment the body needs to relax. If just before you sleep you read a worrying news story, a discussion in networks or a message that alters you, your brain is kept on alert and fails to disconnect. This directly affects the ability to rest and, over time, can contribute to sleep disorders such as insomnia.
