Electric Blankets: Memory Foam's Fiery Foe?
20 Nov
Summary
- Electric blankets can damage memory foam mattresses by overheating.
- Old electric blankets pose a significant fire risk, many failing safety tests.
- Heated throws or layering offer safer, energy-efficient warming alternatives.
As winter temperatures fall, electric blankets are a popular choice for warmth, but pairing them with memory foam mattresses is strongly discouraged. Memory foam is designed to contour with body heat; introducing an electric blanket's warmth can push it beyond safe limits, potentially causing material degradation and reducing its lifespan. This overheating also poses risks to personal health, leading to disturbed sleep and dehydration.
Beyond mattress damage, old electric blankets present a serious fire hazard. Government data indicates around 43 fires each year are linked to faulty electric blankets, with 99% involving blankets over 10 years old. Many older blankets also fail safety inspections. Experts advise replacing electric blankets after ten years or immediately if visible wear occurs, such as exposed wires or frayed fabric.
To stay warm safely and economically, consider alternatives like heated throws used on top of bedding, or layering with flannel or brushed cotton sheets. Opting for a higher tog duvet (13.5+) and wearing breathable natural-fiber sleepwear can also improve warmth. Maintaining an ideal room temperature of around 18°C and ensuring curtains are drawn can further enhance coziness without compromising safety or mattress integrity.
