<\/figure>\nQuand il s\u2019agit de la fa\u00e7on dont la lumi\u00e8re affecte le corps humain, en particulier nos yeux, il est tout au sujet de la longueur d\u2019onde; plus la longueur d\u2019onde est longue, moins elle a d\u2019impact sur vous. La lumi\u00e8re rouge et verte a des effets minimes, car ils sont moins de 550 nanom\u00e8tres (nm), tandis que la lumi\u00e8re ultraviolette, \u00e9galement connue sous le nom d\u2019UV, est plus nocive \u00e0 400 nm.<\/p>\n
La lumi\u00e8re bleue, dont la longueur d\u2019onde est d\u2019environ 470 nm, est le plus souvent associ\u00e9e \u00e0 la perturbation de nos rythmes circadiens.<\/p>\n
\u00ab Le plus grand nombre de preuves que nous avons de la fa\u00e7on dont la lumi\u00e8re bleue affecte votre sant\u00e9 se fait \u00e0 travers notre horloge biologique \u00bb, dit-il. \u00ab\u00a0La lumi\u00e8re bleue supprime en fait la m\u00e9latonine, l\u2019hormone lib\u00e9r\u00e9e dans notre cerveau pour nous aider \u00e0 nous endormir et \u00e0 rester endormis la nuit. Si vous vous exposez \u00e0 la lumi\u00e8re bleue la nuit, cela peut vous rendre moins somnolent.<\/p>\n
Alors que beaucoup de diff\u00e9rentes couleurs de lumi\u00e8re ont cet effet, Mike cite une \u00e9tude de Harvard qui a trouv\u00e9 la lumi\u00e8re bleue supprime la m\u00e9latonine \u00e0 pr\u00e8s de deux fois le taux de lumi\u00e8re verte, et d\u00e9place le rythme circadien deux fois plus.<\/p>\n
Il y a un aspect positif \u00e0 cela. Lorsque vous vous r\u00e9veillez le matin, l\u2019ouverture des nuances pour laisser entrer la lumi\u00e8re du jour aidera \u00e0 vous r\u00e9veiller, car il contient de la lumi\u00e8re bleue et contribuera \u00e0 la suppression de cette hormone du sommeil, r\u00e9initialisant le rythme circadien pour la nuit suivante.<\/p>\n
Les conseils de Mike pour minimiser les effets de la lumi\u00e8re bleue sur nos habitudes de sommeil sont d\u2019avoir z\u00e9ro temps d\u2019\u00e9cran pendant un minimum de 2 heures avant le coucher, et d\u2019utiliser des lumi\u00e8res plus grad\u00e9es dans votre maison le soir. Il sugg\u00e8re \u00e9galement des lunettes bleues \u00e0 l\u2019\u00e9preuve de la lumi\u00e8re si vous \u00eates tenu d\u2019utiliser un \u00e9cran pour le travail tard dans la nuit.<\/p>\n
Contrairement \u00e0 l\u2019opinion populaire, \u00eatre expos\u00e9 \u00e0 la lumi\u00e8re bleue par l\u2019interm\u00e9diaire d\u2019\u00e9crans d\u2019ordinateur portable et\u00a0de t\u00e9l\u00e9phone ne<\/em>\u00a0cause pas de fatigue oculaire, dit Mike; cela se produit en raison de la concentration intense et la concentration, qui implique souvent moins de clignement des yeux, ce qui conduit \u00e0 la s\u00e9cheresse et l\u2019irritation. Cela peut \u00eatre combattu en restant \u00e0 au moins 2 pieds de votre \u00e9cran, en utilisant des gouttes oculaires, et en utilisant la r\u00e8gle 20\/20\/20: toutes les 20 minutes, regarder un point fixe 20 pieds de distance pendant 20 secondes pour d\u00e9tendre les yeux.<\/p>\n \n","protected":false},"excerpt":{"rendered":" Voici ce que vous pouvez faire pour minimiser les effets.
