EN： This sentence reflects a modern shift in wellness and psychological discourse, moving away from self-blame ('personal failing') toward evolutionary psychology. In contemporary Western societies, there is an increasing effort to destigmatize mental health and sleep struggles by framing them as natural biological responses to unnatural modern environments.
中文： 這句話反映了現代健康與心理學論述的轉變，即從自我譴責（「個人的失敗」）轉向演化心理學的視角。在當代西方社會中，人們越來越努力透過將心理健康與睡眠問題框架為「對非自然現代環境的自然生物反應」，來消除這些問題的污名化。
EN： Inversion in conditional sentences (First Conditional). The auxiliary 'Should' is placed at the beginning of the clause to replace 'If' (i.e., 'If society should fail...'). This structure is highly formal and is used to express a hypothetical situation that is possible but perhaps less likely, or simply to elevate the register of the writing.
中文： 條件句中的倒裝（第一類條件句）。助動詞「Should」被置於句首以取代「If」（即「If society should fail...」）。此結構極為正式，用於表示可能發生但機率較低的假設情況，或單純用以提升寫作的文體層次。

EN： The sentence reflects a growing discourse in Western public health and sociology regarding 'sleep hygiene' and the 'sleep deprivation epidemic.' In modern, highly competitive societies, sleep is no longer seen merely as a biological necessity but as a socio-economic issue. The term 'epidemic' (traditionally used for infectious diseases) is metaphorically applied here to highlight the systemic and widespread nature of sleep loss in contemporary life.
中文： 此句子反映了西方公共衛生與社會學界對於「睡眠衛生（sleep hygiene）」和「睡眠不足流行病」日益增加的探討。在現代高壓競爭的社會中，睡眠不再僅被視為生理需求，而被視為一種社會經濟議題。這裡將傳統用於傳染病的「epidemic（流行病）」一詞作隱喻性使用，旨在強調現代生活中睡眠不足問題的系統性與普遍性。
