Research suggests that learning the Alexander Technique is beneficial for a range of health conditions; high quality randomised controlled trials show it can lead to reductions in back pain and neck pain, and reduced disability in people with Parkinson’s disease. Other research suggest improvements in breathing and improved balance from learning the technique. See here for further information on specific conditions.
There is also evidence to suggest that learning the Alexander Technique can improve overall wellbeing. People who have learnt the technique report increased self-awareness, calmness and confidence, and greater control over their actions. It has also been shown to help performance anxiety and improve mood.
