That kind of headline is designed to grab attention without saying the actual hazard, so it leaves you guessing.
From similar firefighter warnings, this usually refers to everyday household habits that can become dangerous when done near a sleeping person, especially near the head or bed. Common examples include:
- Charging a phone on/under a pillow or bed → heat buildup can lead to burns or fire risk
- Using incense, candles, or mosquito coils indoors while sleeping → smoke + fire risk + poor air quality
- Sleeping with a phone or device overheating on the bed
- Blocked ventilation near the head (like heavy bedding covering face/airflow)
- Gas leaks or carbon monoxide exposure (more serious, often called a “silent killer” because there’s no smell)
The reason firefighters warn about it is simple: when you’re asleep, you don’t notice heat, smoke, or fumes early enough to react.
