The dome is certainly safe to use during your pregnancy. In fact, the dome does not have any contraindications through its use of LED therapy, Binaural Beats, and our low power static magnet therapy system. It is actually quite beneficial because it can help calm your nerves, balance your chakras and energy centers, align your body/mind/spirit, and visualize a healthy pregnancy and send nurturing energy to your growing baby! However, if you have a concern please consult with your doctor or therapist.
