So why would happiness increase with age? One theory is that, as people get older, they become more thankful for what they have and have better control of their emotions. They also spend less time thinking about bad experiences.
The findings appeared in the Proceedings of the National Academy of Sciences.
Happiness is not the only thing that apparently improves with age. In a study published this year, people in their 80s reported the fewest problems with the quality of their sleep.
Researchers surveyed more than 150,000 American adults. The study, led by Michael Grandner at the University of Pennsylvania, appeared in the journal Sleep.
The original goal was to confirm the popular belief that aging is connected with increased sleep problems. The survey did find an increase during middle age, especially in women. But except for that, people reported that they felt their sleep quality improved as they got older.研究人员还考虑了诸如养育子女、失业或单身等因素可能产生的影响。但他们发现这类因素不会影响到和年龄相关的幸福感水平。
那么，为什么幸福感会随着年龄增长呢？有一种理论认为，年事愈高，感恩知足之念愈强，情绪自控能力也随之见长。上了年纪的人们很少花心思回想那些不愉快的经历。
该研究结果刊登于《美国国家科学院汇刊》。
幸福感不是唯一随着年龄而显著增长的事物。今年发表的一项研究称，80来岁的人反映的睡眠质量问题最少。
研究人员调查了超过15万美国成年人。该研究由宾夕法尼亚大学的Michael Grandner负责，其结果刊登于《睡眠》一刊。
该研究最初的目的是为了确认睡眠问题会随着年龄而增多的大众观点。调查发现，在中年人尤其是中年妇女中的确存在睡眠问题随年龄而增加的现象。但是除此之外，人们反映随着年龄增加，他们感觉睡眠质量得到了改善。
