There is absolutely no objection to grounding with a pacemaker or a defibrillator. Just like walking barefoot outside is not discouraged if you wear a pacemaker. Your pacemaker will have less work over time, because by the more even cell voltage, your blood circulation now runs better. Due to the improved blood viscosity, your system also gets a faster oxygen supply, and this has a relaxing effect. These are just some of the many health benefits of grounding.Grounding, while sleeping and/or working, has a very soothing effect on your cardiovascular system and is therefore very beneficial for your general health.Give it some time because worn paths sometimes need some time to recover, but grounding always works and for everyone regardless of age or condition.
