Why does my electric blanket give me a mild shock when I touch it?

Small static discharges can occur with electric blankets in dry conditions, but a sharp or repeated shock should be treated cautiously. The manuals explain that static is more likely in low-humidity rooms and can often be reduced by using cotton bedding and reducing friction on the surface. fileciteturn0file5turn0file10

1. Stop the test if the shock feels sharp or happens every time you touch the blanket. Expected result: a one-off static discharge is usually brief, but repeated shocks need caution.
2. Use the blanket with cotton sheets and avoid synthetic bedding directly on top. Expected result: less static should build up between the fabrics.
3. Check whether the room air is very dry. Expected result: static often reduces when humidity is improved.
4. Make sure the blanket is fully flat and not rubbing against loose bedding. Expected result: fewer creases and less movement should reduce static build-up.
5. If the shock continues or feels like an electric fault rather than static, unplug the blanket and stop using it. Expected result: the product should not be used again until it has been checked.

Do not use the blanket if shocks occur together with smell, heat spots, visible damage or intermittent power. If the issue remains unresolved or safe use is uncertain, contact the retailer or store where it was purchased. fileciteturn0file5turn0file10turn0file11
