We carry complex communities of bacteria, fungi, viruses & other microorganisms throughout the gut, lungs, mouth, skin & other tissues. These organisms influence immune function, inflammation, metabolism, neurotransmitter activity, barrier integrity & overall biological stability.\nIf electromagnetic exposure can alter microbial growth, metabolism, oxidative stress responses, gene expression, biofilm behavior or fungal activity, then EMFs may affect human health indirectly as well as directly.\nThat creates a much larger biological pathway:\nEMF exposure → microbial stress response → altered microbial metabolism & behavior → altered metabolites, inflammatory signaling & oxidative stress → immune dysregulation, neurological effects & systemic illness.\nThis may be especially important with fungi because fungi respond dynamically to environmental stress & are capable of producing powerful secondary metabolites, including mycotoxins. Research should examine whether chronic RF/EMF exposure can influence fungal growth, sporulation, biofilm formation, virulence or secondary metabolite production both inside the human body & within water-damaged indoor environments.\nThe human body should therefore be studied as a complete biological ecosystem, not as isolated human cells.\nWe may actually be looking at two systems being exposed simultaneously:\nthe human host\n&\nthe microbial ecosystem living within that host.\nThose systems continuously interact.\nA relatively weak environmental signal would not necessarily need to directly destroy human tissue to create a substantial biological effect if that signal changes the behavior of organisms capable of replication, communication, biofilm formation & chemical production.\nThis is why HHS should investigate the intersection of bioelectromagnetics, microbiology, mycology, mycotoxicology, neuroscience, immunology & microbiome science.\nThe question should no longer be only:\n“What do electromagnetic fields do to human cells?”\nWe also need to ask:\n“What do electromagnetic fields do to the microorganisms living inside us, & what do those microorganisms then do to the human body?”\nUntil that interaction is properly investigated, we may be studying only half of the biological picture.","attachments":["https://downloads.regulations.gov/HHS-OASH-2026-0397-4154/attachment_1.pdf"],"attachment_inventory":true,"withheld":false,"source":"https://www.regulations.gov/comment/HHS-OASH-2026-0397-4154","tags":["biology-metabolism","policy-standards","research-evidence"],"source_hash":"a6ac6bf277b378b85cbec1463dea8b18a3682211e4a4036a7533aa8bd4e1d42c","slug":"biology-metabolism-comment-4154","classification":{"id":"HHS-OASH-2026-0397-4154","body_sha256":"7ab0bfb4d74cb9adeb11ad72fede487d5345d4ad4c53cdcced297dc24c87b0a7","status":"ai_reviewed","primary_topic":"mechanisms","topics":[{"id":"mechanisms","evidence":"at creates a much larger biological pathway:\nEMF exposure → microbial stress response → altered microbial metabolism & behavior → altered metabolites,"},{"id":"research","evidence":"formation & chemical production.\nThis is why HHS should investigate the intersection of bioelectromagnetics, microbiology, mycology,"},{"id":"neurological","evidence":"g & oxidative stress → immune dysregulation, neurological effects & systemic illness.\nThis may be especially important with fungi "},{"id":"environment","evidence":"oduction both inside the human body & within water-damaged indoor environments.\nThe human body should therefore be studied as a complete biolog"}],"summary":"The commenter proposes that EMFs could affect health through microbial and fungal responses, metabolites and immune signaling, and asks HHS to research the interaction between electromagnetic exposure and the human microbiome.","reviewed_at":"2026-10-22T20:03:42Z","review_method":"Complete submitted comment-text review with neutral attributed summaries and exact evidence; attachments and external materials not reviewed.","review_source_sha256":"280ad757c4cf2253407b174d955583a4b453b26f1cd3bbabf13d5af60e6e85cf","source_url":"https://rfsafe.net/hhs-comments/data/catalog.json","scope":"Original comment body; attachments excluded"},"forum_topics":["mechanisms","research","neurological","environment"],"primary_topic":"mechanisms","forum_title":"The commenter proposes that EMFs could affect health through microbial and fungal responses, metabolites …"}
