Chemical Imbalance has a lot to do with the well being of an individual. According to the theory of chemical imbalance, low levels of the brain chemical serotonin lead to depression and depression medication works by bringing serotonin levels back to normal. The truth is that the causes of depression are far more complex than a simple deficiency in serotonin or other neurotransmitters.
Studies have shown that using Hypnosis it is able to convince a person's sub-conscious mind to begin to eat a proper diet and exercise more often to help bring the serotonin levels back up to normal levels.
