Want To Feel Younger? Your Sleep May Have More To Do With It Than You Think
Ever notice how a bad night's sleep can make you feel like you've aged five years overnight? You wake up groggy, sluggish, and already counting down the hours until bedtime.
After a good night's rest, though, you might feel more energetic, focused, and ready to take on the day. It turns out that how rested you feel could be connected to more than your energy levels.
A new study suggests that sleep may also play a role in how old you feel compared to your actual age.
About the study
The research, published in the Journal of Sleep Research, used data from the English Longitudinal Study of Ageing.
Researchers analyzed information from 11,050 middle-aged and older British adults, then checked their findings against a separate group of 1,800 adults to see if the same patterns showed up.
Participants reported how well they slept, how many hours they typically got, and whether they had trouble falling asleep, staying asleep, or waking up feeling rested. They also answered questions about how old they felt compared to their actual age.
This gave researchers a way to explore whether sleep habits were connected to feeling younger or older, and whether that relationship continued over time.
Waking up refreshed may be a bigger factor than sleep duration
People who reported better sleep quality and longer sleep tended to feel younger than their actual age. And the connection appeared to go both ways. Over a four-year follow-up, people who initially felt younger also tended to report better sleep quality later on.
One detail stood out: waking up feeling unrefreshed had the strongest link to how old people felt, compared to how long they slept or whether they struggled to fall or stay asleep.
That makes sense when you think about it.
Spending eight hours in bed doesn't guarantee you'll wake up feeling rested. You can technically get a full night's sleep and still feel like you barely closed your eyes.
According to these findings, that lack of refreshment may be more closely tied to feeling older than your actual sleep duration.
The researchers also found that the relationship varied somewhat by age, sex, and long-term illness in their main group of participants.
However, these differences didn't show up consistently when researchers tested their findings in the separate group of 1,800 adults, so it's too early to draw firm conclusions about those factors.
What this could mean for healthy aging
How old you feel isn't necessarily a reflection of what's happening on your birth certificate. Your day-to-day health and well-being may shape that perception, and sleep could be part of the picture.
It's also possible that the relationship works both ways.
Poor sleep might leave you feeling older and less energetic, while feeling older (or the health factors contributing to that feeling) could also affect how well you sleep.
The researchers suggest that sleep quality and subjective age could be useful areas to focus on when supporting healthy aging.
The study doesn't prove that better sleep will make you feel younger, but it does highlight how closely rest and our experience of aging may be connected.
How to get more out of your sleep
Rather than focusing exclusively on how many hours you spend in bed, pay attention to how you feel when you wake up. A couple of habits worth keeping in mind:
- Check in with your morning energy: Do you usually wake up feeling rested, or does it take half the morning to feel human again? Pay attention to these patterns over time, rather than judging your sleep by the clock alone.
- Don't brush off ongoing sleep problems: If you're regularly waking up exhausted, struggling to fall asleep, or tossing and turning throughout the night, consider discussing it with a health professional. Persistent sleep issues aren't something you have to accept as an inevitable part of getting older.
The takeaway
Sleep might be doing more for healthy aging than helping you avoid that afternoon slump.
Feeling rested and feeling younger appear to go hand in hand, and waking up refreshed may be an especially important piece of the equation. So perhaps it's time to give your mornings as much attention as your bedtime.
