Hypnosis that's conducted by a trained therapist or health care professional is considered a safe, complementary and alternative medicine treatment. However, hypnosis may not be appropriate in people with severe mental illness.

Adverse reactions to hypnosis are rare, but may include:

  • Headache
  • Drowsiness or dizziness
  • Anxiety or distress
  • Creation of false memories

Use special caution before using hypnosis for age regression to help you relive earlier events in your life. This practice remains controversial and has limited scientific evidence to support its use. It may cause strong emotions and can alter your memories or lead to creation of false memories.
