Hypnosis is a modified state of consciousness that allows us to access resources that we possess, without necessarily consciously knowing about them.
Hypnosis is a brief therapy. It means that the therapist works with the person to reach their goal in a reduced number of sessions.

There is no particular risk, but only some contraindications. For example, it is recommended not to listen to a hypnosis session while driving.
Hypnotherapy is recommended for both psychological and physical problems.
Hypnotherapy does not replace medical care. It can intervene in addition to a medical follow-up.
