LA UE ES PREOCUPA M\u00c9S PER L’EFICI\u00c8NCIA ENERG\u00c8TICA QUE PER LA NOSTRA SALUT<\/h3><\/div>

Segons Carles Suri\u00e0, enginyer expert en mesuraments de t\u00f2xics, la Uni\u00f3 Europea va prohibir les bombetes incandescents i recentment les hal\u00f2genes sense tenir en compte els efectes que la il\u00b7luminaci\u00f3 LED actual provoquen en la salut de les persones.<\/p>

Som conscients de com ens afecta la il\u00b7luminaci\u00f3 artificial di\u00e0riament? I dels efectes de la llum blava i de la llum vermella? El control per a l’estalvi de l’energia i d’altres pol\u00edtiques econ\u00f2miques han deixat de banda el benestar i la salut de la societat.<\/p><\/div><\/section>

Exemple d’aix\u00f2 \u00e9s la recent prohibici\u00f3 de la distribuci\u00f3 de les bombetes hal\u00f2genes (1\/9\/2018), i anys enrere el de les incandescents (1\/9\/2007), per part de la Uni\u00f3 Europea, donant pas a la il\u00b7luminaci\u00f3 LED, de la qual la majoria de persones en desconeix els efectes en la salut. Segons Carles Suri\u00e0, enginyer expert en mesuraments de t\u00f2xics, \u201cels interessos de la UE van per altres camins. Es preocupa m\u00e9s per l’efici\u00e8ncia energ\u00e8tica que no pas per la nostra salut. I \u00e9s que, com indica l’expert, la llum LED presenta un espectre lum\u00ednic no ideal<\/strong> (visi\u00f3 no equilibrada de tota la gamma de colors) i genera ones electromagn\u00e8tiques<\/a>, cosa que dificulta la identificaci\u00f3 dels colors i incrementa l’estr\u00e8s<\/strong>. No obstant aix\u00f2, els llums incandescents o hal\u00f2gens generaven un espectre llumin\u00f3s complet i no emetien ones electromagn\u00e8tiques.<\/p>

Tot aix\u00f2 es veu reflectit en el dia a dia. Per exemple, tant als ambients de treball com a les escoles hi sol haver des de primera hora i fins a \u00faltima de la tarda il\u00b7luminaci\u00f3 artificial amb una forta concentraci\u00f3 de llum blava produ\u00efda per la llum LED, que estimula l’adrenalina. Tot aquest temps d’exposici\u00f3 retarda la producci\u00f3 de melatonina i fa que tant joves com adults estiguin m\u00e9s alterats del compte<\/strong>. \u201cA la natura la il\u00b7luminaci\u00f3 evoluciona de forma cont\u00ednua al llarg del dia. Els primers raigs tenen una proporci\u00f3 m\u00e9s gran de blau i els \u00faltims ens proporcionen una llum vermellosa. El nostre ritme circadi\u00e0 est\u00e0 adaptat a aquesta evoluci\u00f3 di\u00e0ria de la llum i la seva alteraci\u00f3 provoca trastorns cardiovasculars, problemes de son i gastrointestinals<\/strong>, entre d’altres efectes, segons la literatura cient\u00edfica.<\/p>

Davant d’aquesta problem\u00e0tica, l’expert proposa centrar-se en l’\u00e9sser hum\u00e0 i deixar en segon pla les pol\u00edtiques econ\u00f2miques<\/strong>: \u201cCal imitar la natura. El futur de la il\u00b7luminaci\u00f3 passa per aconseguir la imitaci\u00f3 perfecta de la il\u00b7luminaci\u00f3 natural, ja que \u00e9s el ritme de la natura el que aconseguir\u00e0 un major rendiment en les persones\u201d. Afortunadament, el LED \u00e9s una tecnologia amb un gran potencial de desenvolupament, cosa que permetr\u00e0 avan\u00e7ar cap a una soluci\u00f3 m\u00e9s saludable.<\/p>

Molt aviat els projectes d’il\u00b7luminaci\u00f3 se centraran en l’\u00e9sser hum\u00e0 (sota el ja conegut concepte Human Centric Lighting<\/em>) i tindran com a objectiu optimitzar aspectes del comportament hum\u00e0, una realitat molt diferent de la que es troba actualment a moltes oficines i col\u00b7legis. \u201cQuan ens despertem al mat\u00ed, la llum del dormitori tindr\u00e0 m\u00e9s proporci\u00f3 de blau, cosa que incrementar\u00e0 l’adrenalina i ens activar\u00e0. Despr\u00e9s, a l’oficina o a l’escola, la proporci\u00f3 de blau disminuir\u00e0 a mesura que avanci el dia, per evitar aix\u00ed un exc\u00e9s d’adrenalina. D’aquesta manera hi haur\u00e0 menys treballadors alterats i menys nens sobreexcitats<\/strong>. I al capvespre, a casa, la llum tindr\u00e0 un component vermell m\u00e9s gran, estimulant la producci\u00f3 de melatonina per poder dormir m\u00e9s relaxats\u201d, conclou.<\/p><\/div><\/section>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
