In a study, researchers from Yale University tested the effects of hypnosis right before outpatient surgery.
The researchers said anxiety levels of those who underwent hypnosis were 68 percent lower after hypnosis.
Researchers said it's important to cut down on anxiety about surgeries because anxiety has been linked to increased need for painkillers and longer hospital stays.
The hypnotic session lasted for 45 minutes with an anesthesiologist trained in hypnosis on hand, suggesting relaxation and well-being.
