I have been using these sheets for several months now, and I will honestly say that there is an effect, but not as magical as they promise. I started out with my doubts, but decided to try it because of frequent sleep problems. At first, I noticed that I fell asleep faster and felt a little more alert in the morning. Perhaps it was a placebo, but I felt better. I believe that grounding really does affect your overall well-being, although you shouldn't expect great miracles. By the way, here I came across a discussion where users share their reviews: grounding bedsheets. I recommend reading, there are many opinions. Some, for example, say that blood circulation has improved. In any case, it is better to try it yourself, because the effect is different for everyone.
