You probably remember the salt-crystalline NaCl formula from school time chemistry lessons. Sodium and chlorine ions, which are built on alkalis come in contact with air.
When the lamp is heated around the salt, air movement begins. Negative charged chlorine ions lead to ion polarization in the light air so that the air particles produce a negative charge that is necessary for health.
Such particles can be found in large amounts in the forest (about 1000 cm3), near the waterfalls, and in the sea (about 2000 cm3) and also in the mountains where the longevity of such particles is 20 000 cm3.
We have 80 to 100 negative aerial cubic meters in the apartments. In other words, we breathe dead air. Elements of organic salt are natural air ionizers without contraindications and with no possibility to overdose.
The salt crystal itself is also a natural energy harmonizer. In the presence of him, people are less nervous, a stress is recovered faster, sleep is better, people are having less disputes, etc.
