Air-ionometry of hot, dry dessert winds(Sharav) and treatment with air ions of weather-sensitive subjects


Hot dry winds (Sharav) produce increased ionisation of the atmosphere, values for positive and negative ions going up from an average of 1, 000 per cm3 to 1, 500. There was almost always a slight preponderance of the positively-charged small ions. This increased air ionisation induces serotonin release in about one-quarter of the population with multiple complaints of a typical serotonin irritation syndrome. In 75% of 129 subjects suffering from serotonin ailments, the treatment with negative air ions (Ionotron) with an output of 3.5 × 105 ions/(cm3 · sec) at 1 m distance produced prophylactic and therapeutic relief when the patients were kept in a room of up to 4 × 4 m size. These results were controlled by serotonin and 5-HIAA urinalysis.
