Already effective at alleviating stress and anxiety, researchers in Denmark in the 1990s took a look into how reflexology could help headache and migraine patients.
One of the landmark studies, published in a 1999 edition of Alternative Therapies in Health and Medicine, took 220 patients and had 78 reflexologists treat them for six months.
After just three months, 81% of the patients claimed that their treatments either considerably helped or completely healed their headache problems, and 19% who previously took drugs to manage their condition were able to stop their medication altogether.
