Luce e benessere.
Luigi Campanella, già Presidente SCI
Da chimico ho sempre rispettato il ruolo della luce nei processi biologici che regolano la nostra vita. Questo rispetto si è trasformato in interesse per la fotochimica soprattutto riferita alla fotocatalisi ed alla capacità di alcuni composti semiconduttori di esercitare all’interno di questo processo un ruolo fondamentale di agenti foto-catalizzatori.
Tale ruolo è strettamente correlato alla capacità di alcune radiazioni luminose di promuovere un elettrone dalla banda di valenza a quella di conducibilità esaltando il passaggio di un composto isolante nella categoria dei conduttori. Partendo da questi dati e dalla analisi completa di queste reazioni i cui prodotti secondari sono radicali liberi dell’ossigeno si resta affascinati dal confronto diretto con quanto avviene nel corpo umano.
La luce è essenziale per la vita umana perché regola il nostro ritmo circadiano, influenzando il sonno e l’umore attraverso la serotonina e la melatonina, il primo ormone del benessere, il secondo ormone del sonno.
La luce stimola inoltre la produzione di vitamina D, importante per la salute di ossa e cervello. La luce naturale migliora le prestazioni cognitive e la concentrazione, mentre la luce artificiale può svolgere un ruolo nel trattamento di disturbi come la depressione stagionale e la sindrome del tramonto.
Oltre a benefici fisici, la luce ha un forte valore simbolico, rappresentando la conoscenza, la verità e la salvezza. Nella filosofia infatti la luce è spesso associata alla conoscenza e all’intelletto, guidando l’essere umano verso la verità e la comprensione del mondo.
La luce naturale regola il ciclo sonno-veglia, ma un’esposizione eccessiva alla luce, soprattutto a quella artificiale notturna, può alterare questo ritmo, riducendo la produzione di melatonina e peggiorando la qualità del riposo. La luce naturale favorisce migliori prestazioni in termini di concentrazione, memoria e reattività. L’uso di luci brillanti può essere utile per i malati di demenza, contribuendo a ridurre i sintomi depressivi e il deterioramento cognitivo.
L’eccessiva luce artificiale, soprattutto nelle città, può alterare i ritmi biologici, portando a un aumento delle ore di sonno più tardive e a disturbi del sonno. Da quanto ora detto emerge, come spesso avviene discutendo di fenomeni naturali, che anche rispetto al ruolo della luce mondo animale e mondo minerale, che sembrano così lontani fra loro, in effetti lo siano molto meno di quanto sembri.
Promozione di un elettrone e produzione di un ormone quanto sono sconnessi e distanti??
