Sleep by Age: How Many Hours Do You Really Need?
How Much Sleep Do You Need at Every Stage of Life?
If you’re one of those lucky people who drift off the second your head hits the pillow, count your blessings. For many, getting quality sleep feels like an endless struggle. But here’s one thing we all have in common: the amount of sleep our bodies need to function at their best. While it’s obvious that a newborn needs far more rest than a busy professional, the question of how much sleep changes as we age—especially between our 40s, 50s, and beyond—isn’t always so clear.
Let’s break down the recommended sleep durations for adults at different life stages, along with the unique challenges each age group faces when it comes to getting a good night’s rest.
Sleep in Your 40s: The Sweet Spot
By the time you hit your 40s, your sleep habits are likely well-established. You’ve probably perfected your bedtime routine, and if your kids are older, you might finally be enjoying uninterrupted nights. While you may wake up once or twice for a bathroom break or a random noise, your sleep is likely more consistent than in earlier decades.
For adults aged 40 to 50, experts recommend 7 to 9 hours of sleep per night. While 9 hours might feel like a luxury, aiming for 7 to 8 hours is a realistic and beneficial goal for most people in this age group.
Sleep in Your 50s: Navigating Midlife Changes
As you enter your 50s, sleep can become a bit more challenging. This is the decade when many women begin experiencing menopause, with the average age of onset in the U.S. being 51. One of the most common sleep disruptors during this time? Hot flashes. These sudden waves of heat often strike at night, making it difficult to stay asleep.
According to Mayo Clinic, women in this stage of life may also develop sleep disorders like sleep apnea. This condition is linked to the decline in reproductive hormones such as estrogen and progesterone, which previously helped protect against it. In fact, postmenopausal women are 2 to 3 times more likely to develop sleep apnea than their premenopausal counterparts.
Despite these challenges, the recommended sleep duration for adults aged 50 to 65 remains 7 to 9 hours per night. Given the likelihood of waking up at least once during the night, it’s a good idea to head to bed a little earlier to ensure you’re getting enough rest.
Sleep in Your 60s and Beyond: Quality Over Quantity?
Contrary to popular belief, older adults don’t need less sleep—they often need more because the quality of their sleep tends to decline. Sleep apnea, which becomes more common after menopause, can significantly disrupt rest for those over 60. Additionally, changes in circadian rhythms can lead to a condition called advanced sleep phase syndrome, where older adults feel sleepy earlier in the evening and wake up much earlier in the morning.
Dr. Peters, MD, a sleep physician at Virginia Mason Medical Center, suggests that these shifts may be due to changes in the eye, such as clouding of the lens, which affects light perception and, in turn, the body’s internal clock.
For adults aged 65 and older, the recommendation remains 7 to 9 hours of sleep per night. However, achieving this can be tougher due to the factors mentioned above.
Why Sleep Needs Stay Consistent (But Quality Doesn’t)
As you can see, the recommended amount of sleep doesn’t change much across adulthood. What does change is the quality of that sleep and the obstacles that come with aging. Whether it’s hormonal shifts, sleep disorders, or changes in circadian rhythms, getting enough rest becomes more complex as we get older.
Fortunately, there are steps you can take to improve your sleep quality, no matter your age.
Simple Ways to Improve Your Sleep
If you’re struggling to get the rest you need, try incorporating these habits into your routine:
Move Your Body
You don’t need to spend hours at the gym to reap the sleep benefits of exercise. Even a daily walk can help regulate your sleep patterns and improve the quality of your rest.
Practice Mindfulness
Meditation looks different for everyone, but the key is to set aside at least 20 minutes each day to unplug from your phone, computer, and TV. This downtime helps your body and mind relax, making it easier to fall asleep. Sleep apps can also be a great tool for guided relaxation.
Limit Blue Light Exposure
You’ve probably seen ads for blue light-blocking glasses, and they’re worth considering if you use screens before bed. The blue light emitted by phones, tablets, and computers tricks your brain into staying awake. To combat this, try wearing blue light glasses or turning off screens at least an hour before bedtime.
Small changes can make a big difference in how well you sleep. By prioritizing rest and addressing the unique challenges of your age group, you can enjoy deeper, more restorative sleep at any stage of life.
