If you are sleeping less than you used to, you are not alone and you are not necessarily doing anything wrong.
According to the National Institute on Aging, sleep changes with age in predictable, biological ways. The deep sleep phases that restore the body become shorter. The internal clock shifts earlier, so seniors tend to feel tired sooner in the evening and wake earlier in the morning. Sleep becomes lighter and more fragmented.
These are normal changes, not signs of disease. The challenge is that the body still needs roughly the same amount of sleep it always did, around seven to eight hours, according to the National Sleep Foundation. The need doesn't shrink, but the ability to get there does.
What helps may surprise you. Research published in Scientific Reports found that physical activity and social engagement each improve sleep quality in older adults. The key finding is that both are needed. High activity levels with low social contact, or a rich social life without physical movement, produced weaker results. The combination is what works.
According to research from the NIH, social isolation is one of the strongest predictors of fragmented, poor-quality sleep in seniors.
The practical takeaway is that seniors who sleep best tend to be those moving bodies, and staying connected. Worrying about sleep is among the least effective ways to get more of it.
