In this article we will discuss the topic of Negative air ionization therapy, a topic of great relevance and interest today. Negative air ionization therapy has generated numerous debates and controversies, as well as aroused the interest of experts and fans of different disciplines. In this sense, it is important to analyze in detail all the aspects and perspectives related to Negative air ionization therapy, to fully understand its impact and scope in today's society. Throughout this article, we will explore different points of view, relevant data and possible future implications of Negative air ionization therapy, with the aim of offering a complete and enriching vision on this important topic.
Negative air ionization therapy (NAIs) uses air ionisers as a non-pharmaceutical treatment for respiratory disease, allergy, or stress-related health conditions. The mainstream scientific community considers many applications of NAIs to be pseudoscience.[1][2][3][4][5][6] Many negative ion products release ozone, a chemical known to cause lung damage.[7]
For seasonal affective disorder (SAD), a randomized controlled trial (RCT) comparing high (4.5x1014 ions/second) and low (1.7x1011 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.[8] An older RCT conducted by the same authors also found air ionization effective for SAD.[9] A 2007 review considers this therapy "under investigation" and suggests that it may be a helpful treatment for SAD.[10]
An RCT comparing the short-term effects of bright light, an auditory stimulus, and high and low-density negative ions on mood and alertness in mildly depressed and non-depressed adults found that the three first (active) stimuli, but not the low-density placebo, reduced depression on the Beck Depression Inventory scale.[citation needed] The auditory stimulus, bright light, and high-density ions all produced rapid mood changes - with small to medium effect sizes - in depressed and non-depressed subjects.[11]
Researchers have continued to cite a dearth of evidence about the effects of negative air ionization. "The presence of NAIs is credited for increasing psychological health, productivity, and overall well-being but without consistent or reliable evidence in therapeutic effects and with controversy in anti-microorganisms," researchers wrote in a 2018 article published in the International Journal of Molecular Sciences.[5]
