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.

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]
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.
Negative air ions (NAI) are important air component, generally referring to the collections of negatively charged single gas molecules or ion clusters in the air. They play an essential role in maintaining the charge balance of the atmosphere. [1] [2] The main components of air are molecular nitrogen and oxygen.
A number of wearable products marketed as "negative ion generators" have actually been found to contain radioactive thorium or uranium, apparently to generate negative ions as a result of radioactive decay. [9] [10] While the activity is typically low, adverse effects from cumulative exposure to the radioactivity in these products cannot be ...
With a ceramic titanium barrel, negative ion tech for anti-frizz magic, and versatile styling options, this tool is a pro for drying, straightening and volumizing in one go. $31 at Walmart Walmart
Various consumer products such as jewelry, pendants, wristbands and athletic tape are touted as incorporating "negative ion technology"—also advertised under other names such as "quantum scalar energy", "volcanic lava energy", and "quantum science". These products are purportedly infused with minerals that generate negative ions and are ...
negative ion formation: the requirement on the extracted current density from the cesiated ion source is at the limit of the present technology of plasma ion sources. beam optics: the precursor ion beam is generated in a multigrid electrostatic accelerator, having 1280 apertures in each of the 7 grids composing it.
