Grounding mats are generally considered safe for most people. Because the contact is gentle and non-invasive, many people use them as part of their rest or sleep routine without issues.
However, there are a few general precautions. If your home wiring or outlet grounding is not properly installed, a mat may not function correctly and may not deliver the intended grounding effect. Always check that the outlet or grounding rod is properly certified and safe.
Grounding should not replace medical treatment for serious vein conditions. If you have a history of blood clot risk, deep vein disease, vein ulcers or other vascular conditions, you should speak with a doctor before relying on grounding.
Finally, grounding may affect blood flow, viscosity or circulation in subtle ways. If you are on medication that influences blood clotting or circulation, you should get medical advice before use. Use grounding as a wellness support rather than a cure, and monitor how your body responds when you begin using the mat.
