Light as a Broad Spectrum Anti-Microbial
Updated: Apr 1
Studies show that light is an effective anti-microbial with an impressive potential to damage viruses (1)
"Enterococcus has been shown to be sensitive to near- and mid-infrared (IR) light" (Licata et al., 2015; D’Ercole et al., 2016), while the infectivity of Chlamydiaceae can be reduced with near-IR (Marti et al., 2015).
Red light has been shown to reduce cell numbers in some pathogens (König et al., 2000; Martins et al., 2015; de Sousa et al., 2016),
Additionally, infectivity of virus particles can be reduced by exposure to visible light (Richardson and Porter, 2005)
SARS-cov2 can results in Acute respiratory distress syndrome (ARDS) a result of increases in NLRP3 inflammasomes.
Melatonin inhibits NLRP3 inflammasomes. (7)
Studies show that red light therapy elevates melatonin levels.
"The results showed improved sleep and serum melatonin levels in the female athletes, increasing the athletic performance of these athletes."

Melatonin levels decline with age, children have signficnatly higher levles. This may
Vitamin D "activates B and T cells as well as boosting the activity of monocytes and macrophages also contribute to a potent systemic anti-microbial effect."
"The direct invasion by pathogenic organisms may be minimized at sites such as the respiratory tract by enhancing clearance of invading organisms." (5)

In conclusion: Melatonin and Vitamin D may help reduce the inflammatory response to infections.
