So many theories attempt to explain the mechanics behind hypnosis. Some say it causes changes in brain activity while others say it's all a placebo effect, which, of course, brings us to the question of how the placebo effect occurs. Thee are more theories out there, but they are all essentially pointing to one thing - hypnosis is a form of communication with the unconscious mind.
As such, it makes sense to believe that understanding the process begins by knowing the difference between the conscious and unconscious. Conscious and unconscious are two convenient words that try to picture out the activities of the human mind. The "conscious mind" is a bit like your perception of who "you" are. Whether you're reading these words mentally or out loud, it's your conscious mind that's working. The unconscious mind is nothing like that. You can learn these if you take part at any hypnosis training.
The unconscious mind is what takes charge of the autonomic functions in our bodies which we don't even have to think about to work. Examples of these functions or processes are our respiration, heartbeat, immune responses, and the rest. It's where our thoughts, memories and experiences are stored. It's what drives our emotions, habits and responses to other people and the world in general.
On the other hand, the conscious mind is more rational, analytical and critical, and it is always making value judgments. If someone says you should stop smoking because it can kill you, it's unlikely that you will stop smoking on the smoking. Even with a conscious acceptance of the habit's dangers, your conscious mind is not what makes you still a smoker.
Conversely, the unconscious mind is a lot more accepting. It also has the tendency to be more literal, and to always connect information it learns to you as a person. In hypnosis, the critical conscious mind will be bypassed with the use of linguistic or relaxation techniques, and the hypnotist will communicate directly with the unconscious mind by way of metaphors, associations and patterns, which make up the only language it understands.

Hypnosis involves providing the unconscious mind with fresh and more helpful information. It may be used to alter associations, so that smoking, for example, will no longer be perceived by the smoker as a pleasurable activity, and will be taken as a potentially fatal habit. It can also be effective in making a person cope better with hardships, such as being able to handle stress without having a nervous breakdown.
Because the unconscious mind takes care of our autonomic bodily processes, hypnosis can also create physical changes. One perfect example is pain management. The mind affects our pain awareness all the time. Do you ever wonder why chefs never seem to be affected by burns anymore, unless it's something really serious? We all have that experience - finding a bruise on our arm and not knowing how it got there.
In short, hypnosis works by influencing our knowledge of reality, by directly shaping our unconscious mind where most of our problems and their answers reside. Check out these hypnotherapy course for more details.
