Hypnosis has been around for years! Just read the research!

• A study by Olness (1985) showed that children trained in
  self-Hypnosis could significantly alter their tissue levels of oxygen as
  measured by transcutaneous PO2 measures
•  In a 1979 research study by Jackson, subjects with Hypnotic
  ability were shown to improve their aerobic performance significantly in
  response to postHypnotic suggestion. In addition, subjects with high Hypnotic susceptibility significantly improved their performance in physical exercise using postHypnotic suggestion
• Omer (1986a, 1986b, 1987a) found that frequency of physical
  complaints and the general level of anxiety were correlated with premature labor and premature contractions. A brief technique emphasizing the use of
  self-Hypnosis was employed as an adjunct to pharmacological treatment. The prolongation of pregnancy was significantly higher for this group than for the medication-along control group, and infant weight was also significantly
  greater.
•  In a report by David Spiegel in the Harvard Mental Health
   Letter, the following research was cited: One seven-year study showed that 50%
   of patients afraid of flying were improved of cured after Hypnosis treatment
   for a fear of flying.
  
  
  

• In a neurochemical study of Hypnotic control of pain conducted
  by Domangue (1985), patients suffering arthritic pain showed a correlation among levels of pain, anxiety and depression. Anxiety and depression were inversely related to plasma norepinephrine levels. Depression was correlated with dopamine levels and negatively correlated with levels of serotonin and beta endorphin. Following Hypnotherapy, there were clinically and statistically significant decreases in depression, anxiety and pain, and increases in beta endorphin-like substances

•  In studies by Maher-Loughnan (1962, 1970), Hypnosis was shown to
  alleviate the subjective distress of patients with asthma. This change was
  measured either by the number of attacks or the amount of medication that was
  needed when compared to supportive therapy.

•  In a study by Sletvold (1986), normotensive subjects were shown
  able to either increase or decrease their blood pressure significantly with
  Hypnosis.
