Other than focusing on relaxing and indulging positive thoughts during and after the Bio-recharging experience, it is recommended that people properly hydrate with potable water. Also, we recommend you check with your doctor before you schedule your Bio-Recharging therapy. Note: Because no controlled tests or studies have been run on these populations, it is recommended that individuals with Cardiac Pacemakers, Metal Implants, or Epilepsy, or Women who are pregnant, or children under the age of twelve years old, do not be exposed to this therapy.
