20.C总体分析本文主要介绍了对失眠的研究工作。文章第一段指出慢性失眠是一个重要的公共健康问题，但其致病原因仍是个迷。第二段介绍了(美)全国卫生研究所一个专家小组的结论，该小组呼吁对失眠进行广泛的研究。第三段讨论了失眠与其他因素，如疾病、年龄、药物等的关系。第四段介绍了(美)全国卫生研究所对失眠正在进行的研究情况。
全文翻译慢性失眠是一个主要的公共健康问题。而且，太多人正使用未经验证的治疗方法，尽管有些方法确实是有效的。上百万的美国人夜里睡不着觉，躺着数羔羊、喝杯烈酒或吞个药片，希望这会使他们产生困意。然而，专家们一致认为，自作主张乱吃药并不是解决失眠的好方法，导致慢性失眠的原因目前还是一个谜。
几乎有1/3的成年人存在睡眠障碍，而且大约10%的人有白天功能减退的症状，这些症状表明他们确实患上了失眠症。但是，一个由(美)全国卫生研究所召集的专家小组在周三得出这样的结论：尽管(社会上关于长期失眠的)抱怨很多，但科学家们对长期失眠的原因，它对健康的影响以及如何有效地治疗都知之甚少。该专家小组呼吁对失眠症进行广泛研究，指出如果科学家们了解了失眠的潜在原因，他们可能会发现更好的治疗方法。
很多，但不是所有的失眠症被认为伴随着其他健康问题产生，从关节炎、抑郁到心血管疾病。而问题通常是不知道是先产生失眠，还是失眠是其他疾病的结果，以及失眠如何又使其他问题变得更加复杂。撇开其他疾病不说，失眠的可能性随着年龄的增加而增加，而且在妇女中更加普遍，尤其是50岁以后。吸烟、咖啡因及众多的处方药也影响睡眠。
(美)全国卫生研究所今年要花大约2000亿美元用于睡眠的相关研究，其中一些以特定的(睡眠)紊乱为目标，另外一些观察控制睡眠神经系统的潜在科学规律。该机构正等待专家小组的评论以决定对失眠进行的下一步研究工作。
