Pesquisadores do Instituto Polit\u00e9cnico Rensselaer, no Centro de Pesquisa em Ilumina\u00e7\u00e3o, descobriram uma maneira de combater a sensa\u00e7\u00e3o de sonol\u00eancia frequentemente experimentada \u00e0 tarde (conhecida como “sono p\u00f3s-almo\u00e7o”) usando um m\u00e9todo novo: a exposi\u00e7\u00e3o \u00e0 luz vis\u00edvel.<\/p>\n

Durante anos, os pesquisadores sabem que a exposi\u00e7\u00e3o a certos comprimentos de onda da luz vis\u00edvel ajuda a impedir a produ\u00e7\u00e3o de melatonina, um produto qu\u00edmico respons\u00e1vel pela sonol\u00eancia. Sabe-se que a luz azul de comprimento de onda curto que atinge a retina suprime a produ\u00e7\u00e3o de melatonina, enquanto a luz vermelha de comprimento de onda longo n\u00e3o afeta a produ\u00e7\u00e3o de melatonina. O ritmo circadiano, um ciclo biol\u00f3gico de 24 horas respons\u00e1vel pela regula\u00e7\u00e3o do sono, pode ser alterado variando sua exposi\u00e7\u00e3o \u00e0 luz azul durante as horas imediatamente anteriores ao sono. Pesquisas anteriores mostraram que indiv\u00edduos que usavam \u00f3culos de prote\u00e7\u00e3o que bloqueiam a luz azul nos olhos nas horas anteriores ao sono melhoraram significativamente a qualidade do sono e o humor. Novas pesquisas foram conduzidas no RPI, avaliando os efeitos de alerta da exposi\u00e7\u00e3o \u00e0 luz vermelha e azul durante o dia.<\/p>\n

A equipe do RPI decidiu determinar se a exposi\u00e7\u00e3o \u00e0 luz vermelha de longo comprimento de onda, que n\u00e3o est\u00e1 associada \u00e0 supress\u00e3o de melatonina, tamb\u00e9m poderia proporcionar \u00e0s pessoas uma sensa\u00e7\u00e3o de alerta durante o dia. Os indiv\u00edduos foram expostos \u00e0 luz azul ou vermelha, a uma ilumina\u00e7\u00e3o de 40 lux, por 48 minutos de cada vez. Lux \u00e9 uma unidade de ilumina\u00e7\u00e3o que pode ser medida usando um dispositivo como um medidor de ilumina\u00e7\u00e3o<\/a>. Ap\u00f3s as sess\u00f5es de exposi\u00e7\u00e3o \u00e0 luz, as ondas cerebrais alfa, alfa teta e teta (associadas ao relaxamento profundo e \u00e0 sonol\u00eancia) foram medidas usando um eletroencefalograma (EEG). O resultado foi que a luz vermelha, que n\u00e3o suprime a produ\u00e7\u00e3o de melatonina, ainda \u00e9 eficaz na redu\u00e7\u00e3o do poder das ondas cerebrais alfa, alfa teta e teta. Isso indica que a luz vermelha foi capaz de aumentar o estado de alerta e diminuir a sonol\u00eancia nos indiv\u00edduos do teste. Os dados da pesquisa mostram que a luz pode ter um efeito de alerta durante o dia, mesmo sem suprimir a produ\u00e7\u00e3o de melatonina no c\u00e9rebro.<\/p>\n

Os medidores de lumin\u00e2ncia, como o T-10A<\/a> e o T-10MA<\/a> da Konica Minolta Sensing, medem a luz com rapidez e precis\u00e3o, com um formato port\u00e1til conveniente e leituras de dados simples, sendo instrumentos ideais para as suas necessidades de medi\u00e7\u00e3o de luz.<\/p>\n","protected":false},"featured_media":23494,"template":"","learning_center_categories":[1783],"class_list":["post-18310","blog","type-blog","status-publish","has-post-thumbnail","hentry","learning_center_categories-light-display-measurement-br"],"acf":[],"yoast_head":"\r\nUsando
