Is Ionization Therapy for Depression effective?
Two well-conducted studies have looked at the effects of air ionization on winter depression. Both of these studies compared a high-density air ionizer with a low-density ionizer. People sat in a room at home with the ionizer for 30 minutes every morning over a 2-3-week period. People with winter depression who used the high-density ionizer showed much more improvement than those who used the low-density ionizer. No studies have been carried out on air ionization as a treatment for other types of depression.
