发展中国家的城市贫民面临着具有挑战性的生活环境，这可能会干扰良好的睡眠。使用活动记录仪来客观地测量睡眠，我们发现印度金奈的低收入成年人平均每晚只睡5.5小时，尽管他们在床上睡了8小时。他们的睡眠被严重打断，睡眠效率（每次在床上的睡眠时间）与那些患有睡眠呼吸暂停或失眠等疾病的人相当。一项为期三周的随机治疗提供了信息，鼓励和改善家庭睡眠环境，通过诱导更多的床上时间，使睡眠时间增加了27分钟。与专家的预测和大量的睡眠研究相反，增加夜间睡眠对认知、生产力、决策或健康没有明显的影响，并导致劳动力供应的小幅减少。相比之下，在工作场所进行短暂的下午小睡可以将整体结果指数提高0.12个标准差，生产力，心理健康和认知能力显着提高，但工作时间减少。
The urban poor in developing countries face challenging living environments, which may interfere with good sleep. Using actigraphy to measure sleep objectively, we find that low-income adults in Chennai, India, sleep only 5.5 hours a night on average despite spending 8 hours in bed. Their sleep is highly interrupted, with sleep efficiency-sleep per time in bed-comparable to those with disorders such as sleep apnea or insomnia. A randomized three-week treatment providing information, encouragement, and improvements to home sleep environments increased sleep duration by 27 minutes a night by inducing more time in bed. Contrary to expert predictions and a large body of sleep research, increased nighttime sleep had no detectable effects on cognition, productivity, decision making, or well being, and led to small decreases in labor supply. In contrast, short afternoon naps at the workplace improved an overall index of outcomes by 0.12 standard deviations, with significant increases in productivity, psychological well-being, and cognition, but a decrease in work time.
