Grounding sheets are generally considered safe. The grounding plug connects only to the earth ground and does not carry active electricity, so there is no risk of electric shock when used correctly.
However, there are some limitations. First, scientific evidence is still limited, and results are mixed. Many experts say that while grounding may offer benefits, claims about dramatic healing or transformative health effects are not backed by large-scale research.
Also, the benefits may depend greatly on individual differences such as lifestyle, sleep habits, overall health, and consistency of use. It may not have the same effect for everyone.
If you have certain medical conditions, especially related to circulation or severe skin sensitivity, or rely on medical devices that sense electrical signals, you may want to seek medical advice before trying grounding sheets. Treat grounding as a complementary wellness habit, not a replacement for medical treatment or healthy sleep practices.
