What is Known: • Stress may be an important trigger for both tension type headache and migraine in children. • Good data are lacking on the effect of transcendental meditation, hypnotherapy or progressive muscle relaxation as possible stress-reducing therapies in children with primary headaches.

What is New: • Three non-pharmacological techniques, i.e., transcendental meditation, hypnotherapy and progressive muscle relaxation exercises, all result in a clinically significant reduction of headaches and use of pain medication. • No large differences between the three techniques were found, suggesting that children can choose either one of the three techniques based on personal preferences.
