尽管支持该假设的科学证据很少，但关于现代社会普通人群中习惯性睡眠减少及其不利后果的假设已在大众媒体上得到了广泛宣传。同样，人们普遍认为，至少在芬兰，失眠相关症状的患病率正在增加，但相关证据却更少。这些问题很重要，因为已知睡眠时间偏离 7 至 8 小时会增加死亡和健康风险。为了揭示自我报告的睡眠持续时间和失眠相关症状的可能趋势，我们重新分析了 1972 年至 2005 年在芬兰进行的调查的所有可用数据。主要结果是，芬兰自我报告的睡眠持续时间略有下降，特别是在工作年龄的男性中。然而，减少的幅度（约 4%）相对较小，在研究的 33 年时间间隔内，每 10 年减少约 5.5 分钟。 7小时睡眠者的比例有所增加，相应地，8小时睡眠者的比例有所下降，但睡眠时间分布的极端保持不变。初步证据表明，过去 10 年来，工作老年人群中与失眠相关的症状有所增加。总之，芬兰过去 33 年的数据表明，自我报告的睡眠时间普遍减少了约 18 分钟，睡眠投诉有所增加，尤其是在就业中年人群中。
A hypothesis concerning habitual sleep reduction and its adverse consequences among general population in modern societies has received wide publicity in the mass media, although scientific evidence supporting the hypothesis is scarce. Similarly, there is an extensively distributed belief, at least in Finland, that the prevalence of insomnia-related symptoms is increasing, but evidence for this is even sparser. These issues are important because of the known increased risk of mortality and health risks associated with sleep duration deviating from 7 to 8 h. To reveal possible trends in self-reported sleep duration and insomnia-related symptoms, we reanalyzed all available data from surveys carried out in Finland from 1972 to 2005. The main results were that a minor decrease of self-reported sleep duration has taken place in Finland, especially among working aged men. However, the size of the reduction (about 4%) was relatively small, approximately 5.5 min per each 10 years during the 33 years' time interval under study. The proportion of 7 h sleepers has increased and, correspondingly, the proportion of 8 h sleepers has decreased, but the extreme ends of the sleep duration distribution remained unchanged. Tentative evidence suggesting an increase in insomnia-related symptoms among working aged population during the last 10 years was found. In conclusion, the Finnish data during the past 33 years indicate a general decrease in self-reported sleep duration of about 18 min and an increase of sleep complaints, especially among the employed middle-aged population.
