中午小睡，有时也被称为午睡，在人的一生中是普遍存在的。众所周知，除了减少困倦之外，中午小睡还提供了各种好处：巩固记忆，为后续学习做准备，增强执行功能，提高情绪稳定性。即使在前一天晚上获得足够的睡眠，这些好处也是存在的。然而，我们提出了一个悖论：尽管午睡有这些好处，但频繁午睡也与许多负面结果（如认知能力下降，高血压，糖尿病）有关，特别是在老年人群中。即使在统计上控制了相关的健康和睡眠影响因素，这种关联也存在。一个新兴的假设表明，炎症是午睡和健康状况不佳之间的中介，但还需要进一步的研究。考虑到这一点，将午睡作为健康促进剂的“处方”可能还为时过早。在此，我们汇总了睡眠研究的几个分支（如，发育神经科学，认知神经科学，睡眠医学）的发现，以批判性地研究午睡在认知和躯体健康中的矛盾作用。这篇综述揭示了文献中的空白，以指导该领域的研究机会。
The mid-day nap, sometimes called a siesta, is a ubiquitous occurrence across the lifespan. It is well established that in addition to reducing sleepiness, mid-day naps offer a variety of benefits: memory consolidation, preparation for subsequent learning, executive functioning enhancement, and a boost in emotional stability. These benefits are present even if a sufficient amount of sleep is obtained during the night prior. However, we present a paradox: in spite of these reported benefits of naps, frequent napping has also been associated with numerous negative outcomes (eg, cognitive decline, hypertension, diabetes), particularly in older populations. This association exists even when statistically controlling for relevant health- and sleep-affecting determinants. An emerging hypothesis suggests inflammation is a mediator between mid-day naps and poor health outcomes, yet further research is necessary. Given this, it may be premature to ‘prescribe’ naps as a health enhancer. Herein, we aggregate findings from several branches of sleep research (eg, developmental neuroscience, cognitive neuroscience, sleep medicine) to critically examine the paradoxical role of naps in cognitive and somatic health. This review uncovers gaps in the literature to guide research opportunities in the field.
