In today’s world, electronic devices are everywhere, and chargers are often left plugged in around the clock. While this may seem harmless, experts warn that the habit carries overlooked health and safety risks. Even without a phone or laptop attached, chargers continue drawing a small electrical current, generating heat over time. Low-quality or counterfeit chargers are especially vulnerable to overheating, which can degrade insulation and plastic casings, releasing gases such as formaldehyde and other volatile organic compounds.

In enclosed or poorly ventilated spaces, long-term exposure to these emissions may irritate the airways, worsen allergies, or aggravate asthma. Some specialists also note that constant low-level electromagnetic exposure and heat may contribute to headaches, fatigue, or sleep disturbances in sensitive individuals.

Beyond health concerns, fire risk is real. Faulty chargers can spark or short-circuit, especially when left unattended. Unplugging chargers when not in use and choosing certified products are simple steps that improve safety and protect long-term well-being.
