擁抱暗黑：光電學家教你健康好眠的實用手冊

Description

你的夜晚夠「黑」嗎？

睡前還在滑手機？

追劇太精彩，捨不得去睡？

怕黑，非得開小燈才睡得著？

這些都是導致你傷眼又傷身的原因！

面對暗黑√找回睡眠√正確用光√

本書用三大重點，搭配簡單測驗、健康祕訣、光電小知識，一步步帶你養成「暗黑」好習慣！

我們都聽過要日作夜息、愛護眼睛，但是你知道嗎──

◎為什麼我們要擁抱暗黑？

夜晚的人造光打破晝夜明暗的規律交替，影響人體自然節律，除了讓眼睛疲勞不適，更讓大腦不知休息，妨礙退黑激素分泌，導致免疫力下降、內分泌失調，容易引發癌症、快速老化、失智，給健康帶來風險，並影響自然生態。

◎你真的睡得好嗎？

失眠是21世紀的一種流行病，現代人普遍睡眠不足，或是睡眠品質不佳。升學壓力、上網、滑手機、追劇、工作型態等，都可能造成失眠。如何確保自己睡在完全暗黑的環境中，適時調暗燈光，好讓退黑激素正常分泌？配合年齡掌握正確做法，就能睡得香甜、睡出健康與美麗。

◎哪一種光才是好光？

用光就要選「好光」。藍光、紫外光與紅外光對人體的傷害不容小覷，隨著科技發展，今天我們有更好的選擇。讀書、工作和入夜後開燈，選用好光，搭配正確亮度，提升環境照明舒適度，更能減少視覺疲勞，保護眼睛健康，晝夜節律不受干擾。

從現在開始，號召親朋好友一起遠離光害，勇敢向光汙染、藍害說「不」，選好光、用好光，夜夜擁抱暗黑，重拾一夜好眠，享受身體健康的幸福感！
