At the moment of the lightning strike, hundreds of millions of negative air ions will be generated. This is why people feel the air is fresh and clean after rain. It is not only because the rain increases the humidity of the air, but more importantly, the concentration of negative ions in the air has increased significantly. [16]
For Seasonal Affective Disorder (SAD), a randomized controlled trial (RCT) comparing high (4.5x10 14 ions/second) and low (1.7x10 11 ions/second) flow rate negative air ionization with bright light therapy found that the post-treatment improvement percentage was 57.1% for bright light, 47.9% for high-density ions and 22.7% for low-density ions.

An air ioniser (or negative ion generator or Chizhevsky's chandelier) is a device that uses high voltage to ionise (electrically charge) air molecules. Negative ions, or anions , are particles with one or more extra electrons , conferring a net negative charge to the particle.
In a positive corona, all the electrons are attracted inward toward the nearby positive electrode and the ions are repelled outwards. In a negative corona, the ions are attracted inward and the electrons are repelled outwards. The glow of the corona is caused by electrons recombining with positive ions to form neutral atoms.
Negative ion products are products which claim to release negative ions and create positive health effects, although these claims are unsupported. [1] Many also claim to protect users from 5G radiation. These claims are likewise unsubstantiated. A market has developed for these products due to conspiracy theories about 5G. [2]
A negative means you aren’t able to, and positive means you are able to. They can’t tell you for certain whether or not you have, or had, COVID, according to Adalja.
Fluoride toxicity is a condition in which there are elevated levels of the fluoride ion in the body. Although fluoride is safe for dental health at low concentrations, [1] sustained consumption of large amounts of soluble fluoride salts is dangerous.
Electromagnetic radiation can be classified into two types: ionizing radiation and non-ionizing radiation, based on the capability of a single photon with more than 10 eV energy to ionize atoms or break chemical bonds. [1]
