Profesorul de neuro\u0219tiin\u021be Glen Jeffery sus\u021bine c\u0103 iluminatul cu LED-uri afecteaz\u0103 mitocondriile \u0219i submineaz\u0103 s\u0103n\u0103tatea organismului, potrivit publica\u021biei Blic<\/a>.<\/p>\n

El a vorbit, \u00eentr-un interviu pentru The European, despre o \u201ecriz\u0103 clar\u0103 \u0219i actual\u0103 de s\u0103n\u0103tate public\u0103\u201d. Din aceast\u0103 discu\u021bie a pornit compara\u021bia cu azbestul.<\/p>\n

De ce au \u00eenlocuit LED-urile becurile clasice<\/strong><\/h2>\n

\u00cen doar c\u00e2teva decenii, becurile LED au ajuns \u00een case, birouri, \u0219coli, spitale \u0219i pe str\u0103zi. Ele consum\u0103 mult mai pu\u021bin\u0103 energie dec\u00e2t becurile cu incandescen\u021b\u0103 \u0219i dureaz\u0103 mai mult. \u00cen plus, transform\u0103 cea mai mare parte a energiei \u00een lumin\u0103, nu \u00een c\u0103ldur\u0103.<\/p>\n

Jeffery ridic\u0103 \u00eens\u0103 o alt\u0103 \u00eentrebare. Ce se \u00eent\u00e2mpl\u0103 c\u00e2nd dispar din via\u021ba noastr\u0103 lungimile de und\u0103 cu care omul a evoluat?<\/p>\n

Ce au descoperit cercet\u0103torii<\/strong><\/h2>\n

Echipa sa studiaz\u0103 lumina ro\u0219ie \u0219i infraro\u0219ul apropiat. Acestea sunt abundente \u00een lumina soarelui, dar mult mai slabe \u00een spectrul LED-urilor standard. Un studiu publicat \u00een 2025 \u00een Scientific Reports a ar\u0103tat c\u0103 aceste radia\u021bii pot p\u0103trunde \u00een \u021besuturi. Ele trec chiar \u0219i prin haine.<\/p>\n

Un an mai t\u00e2rziu, Jeffery \u0219i Edward Barrett au expus adul\u021bi, timp de dou\u0103 s\u0103pt\u0103m\u00e2ni, la lumini artificiale diferite. Cei expu\u0219i la un spectru mai larg au avut rezultate mai bune la unele teste de percep\u021bie a contrastului cromatic. La grupul cu LED-uri standard nu s-a observat o astfel de \u00eembun\u0103t\u0103\u021bire.<\/p>\n

Potrivit lui Jeffery, mitocondriile transmit mesaje prin s\u00e2nge \u0219i func\u021bioneaz\u0103 ca o re\u021bea de comunicare. Astfel, efectul local al luminii ar putea avea consecin\u021be mai ample \u00een organism.<\/p>\n

Ce spun exper\u021bii europeni<\/strong><\/h2>\n

Compara\u021bia cu azbestul nu are \u00eens\u0103 aceea\u0219i baz\u0103 \u0219tiin\u021bific\u0103, noteaz\u0103 Blic. Azbestul este un carcinogen dovedit la om.<\/p>\n

Comitetul \u0219tiin\u021bific al Comisiei Europene pentru s\u0103n\u0103tate, mediu \u0219i riscuri emergente (SCHEER) a analizat riscurile iluminatului cu LED. Concluzia sa este c\u0103 nu exist\u0103 dovezi privind efecte nocive directe la persoanele s\u0103n\u0103toase, \u00een condi\u021bii normale de utilizare. Comitetul cere totu\u0219i cercet\u0103ri suplimentare, inclusiv despre efectul luminii asupra ritmului circadian.<\/p>\n

Experimentele pe animale au ar\u0103tat c\u0103 expunerea intens\u0103 la anumite lungimi de und\u0103 poate modifica activitatea mitocondrial\u0103 \u0219i metabolismul. Un rezultat ob\u021binut pe \u0219oareci nu dovede\u0219te \u00eens\u0103 c\u0103 un bec LED<\/a> <\/em>obi\u0219nuit are acela\u0219i efect asupra omului, subliniaz\u0103 publica\u021bia.<\/p>\n

Potrivit Blic, deocamdat\u0103 nu exist\u0103 motive conving\u0103toare pentru a scoate becurile LED din cas\u0103.<\/p>\n","protected":false},"excerpt":{"rendered":"
