In our tech-filled lives, chargers and cables often stay plugged in even when not in use.
While this seems harmless, experts warn that it carries hidden health and safety risks. Even idle, adapters draw current and generate heat, especially cheaper or counterfeit models. Over time, this can degrade insulation and release harmful chemicals like formaldehyde and VOCs.
These emissions may worsen asthma, allergies, or airway irritation, particularly in small or poorly ventilated spaces. Some specialists also caution that constant low-level radiation and heat exposure can cause headaches, fatigue, and sleep problems, affecting overall well-being. Children and people with health conditions are most at risk.
Beyond health concerns, fire danger is another issue. Chargers left plugged in can overheat, short-circuit, or spark, and the risk multiplies when several are left unattended. Poor-quality knockoffs make this even more likely.
To reduce risks, experts advise unplugging chargers when not in use and choosing only quality-certified models. While the dangers may appear minor day to day, the combination of toxic emissions, radiation, and fire hazards makes unplugging a small but powerful step toward long-term health and safety.
