While the impact of sleep on cognitive functions such as memory is under extensive study, the role of sleep in modulating a persons' subjective well-being remains largely uncharacterized, especially in groups with psychiatric disorders. To gather more information on this topic a study was conducted with 20 patients suffering from Major Depression (MD) and 20 healthy controls, matched for age, gender and education. All subjects rated their subjective well-being at 10a.m. in the morning. Half of the subjects in each experimental group were given the opportunity to nap in the afternoon between 2p.m. and 3.30p.m., while the other half stayed awake accompanied by controlled activity. All subjects rated their subjective well-being again at 4p.m. Only the group of patients with MD who were given the opportunity to sleep during the day showed a significant improvement in subjective well-being from morning to afternoon. All the other subgroups showed no significant changes across the time interval. The results of this study suggest that depressive patients benefit from daytime naps with regard to their subjective well-being. Further research is needed to determine the exact mechanisms of this improvement.
虽然睡眠对记忆等认知功能的影响正在广泛研究中，但睡眠在调节个体主观幸福感方面的作用在很大程度上仍未得到充分描述，尤其是在有精神障碍的人群中。为了收集更多关于这一主题的信息，对 20 名患有重度抑郁症 (MD) 的患者和 20 名健康对照组进行了一项研究，这些对照组在年龄、性别和教育程度上相匹配。所有受试者在上午 10 点评价他们的主观幸福感。在每个实验组中，一半的受试者有机会在下午 2 点到 3 点半之间小睡，而另一半则在伴有控制活动的情况下保持清醒。所有受试者在下午 4 点再次评价他们的主观幸福感。只有有机会在白天睡觉的 MD 患者组在主观幸福感方面从上午到下午有显著改善。所有其他亚组在时间间隔内均无显著变化。这项研究的结果表明，抑郁患者从白天小睡中受益于主观幸福感。需要进一步研究以确定这种改善的确切机制。
