If you believe in a mind-body connection, then you have likely heard of quantum healing systems. Many people who have a spiritual practice swear by the power of these systems to heal the body, and even fight off serious diseases such as cancer. The scientific basis of these methods rests on the principles of quantum physics and consciousness. Quantum healing practitioners use positive thoughts and visualization to send energy to the body, which they say is able to correct any imbalances.

Traditional medicine, however, scoffs at these claims. It’s hard to deny that a placebo effect does play a role in the efficacy of these therapies, but it also doesn’t diminish the role that doctors, nurses and staff can play by offering patients empathy, a pat on the back, words of encouragement and more.

Deepak Chopra is one of the biggest pioneers in quantum healing, having spent a few years in conventional internal medicine before moving into the field of alternative methods and spiritual practices. He has written more than 90 books that stress the interconnectedness of the mind, body and spirit.

Quantum Touch, a hands-on healing method, relies on the theory of quantum entanglement, which says that particles can be connected no matter how far apart they are. The energy of this method does not come from the practitioner, as they are simply a conduit for redirecting the energy that already exists around the patient. This type of quantum healing can be used for pain relief, reducing inflammation, accelerating wound healing and more.
