Around two and a half years ago I reported on a study that found a 25% drop in reports of sleep disturbances after retirement.
To counter this, about six months ago I wrote about a natural aging process that can harm sleep.
Now it would appear that overall, we should expect our sleep quality to improve as we age.
According to a telephone survey of 150,000 individuals, sleep gets consistently better as we age (although there do seem to be issues when we are in our 40s). Those in their eighties can expect the highest quality sleep.
Of course, it's worth bearing in mind that this study was based purely on subjective opinions - ones which can vary considerably between individuals and vary depending on the mood of the individual when asked about their sleep.
That being said, it does suggest a disconnect between how well we sleep and how well we think we're sleeping.
