According to the scientists negative ions help brain’s alfa waves and increase their amplitude.

 They also have a therapeutic effect on rhinitis, sinusitis, bronchial asthma, allergies, migraines, birth and postoperative pains.

An experiment carried out in the UK in the 1980s on two groups of post-operative patients, one of which was in a high concentration of negative ions (10,000 cubic centimeters) for 3 days, showed 80% faster healing.

Another reason for the therapeutic action of negative ions is that they kill bacteria and viruses. This was established in the 1930s by the Soviet scholar Chiezheski.

All researchers agree that negative ions increase the absorption and absorption capacity of oxygen by accelerating the process of delivering it to the cells and their nuclei.

According to experts  positive ions in the air that we breathe have a negative impact on self-esteem and perception, while their antipodes, negative ions, stimulate them.

Recently it was discovered a German map of World War II , in which were included the regions with negative ionization of the air and the Rhodopes are one of them, specially surrounded by red lines.

Troops from the Third Reich came every six months fir recovering, according to researchers of the phenomenon “Rhodopean air”, which, among other things, has high parameters in the UV spectrum, with a low microbial number and a high phytanthonic density.
