You might wake earlier, remember more nighttime awakenings, or see less “deep sleep” on a watch than you once did. Those changes can prompt useful questions. They should not lead you to assume that nothing can be done when sleep is affecting your life.
What may change with age
Timing may shift
Some people become sleepy earlier in the evening and wake earlier in the morning.
Sleep may be lighter
Nighttime awakenings can become more noticeable, and deep sleep generally decreases across adulthood.
Other factors may enter
Pain, medicines, nighttime bathroom trips, and health conditions can interrupt sleep.
Daytime effects still count
How alert and functional you feel matters more than whether one night's stage chart looks ideal.
Not every change happens to every person. A new or troubling pattern is worth describing to a clinician rather than attributing it to age alone.
Do older adults need less sleep?
Older adults still generally need about seven to nine hours of sleep each night, according to the National Institute on Aging. What may change is the timing or continuity of sleep, not a sudden loss of the need for rest.
What about a low deep-sleep number?
Deep sleep tends to decrease with age, and a watch estimates stages indirectly. A low estimate on one night is not a diagnosis. Look at repeated patterns, your symptoms, and the limits of the device rather than trying to force a particular stage number.

When should you ask for help?
Discuss sleep with a healthcare professional if you repeatedly cannot fall or stay asleep, feel sleepy or fatigued during the day, or someone observes snoring, gasping, or breathing pauses. Bring up pain, new medicines, and nighttime symptoms as well.
Insomnia and sleep apnea can be evaluated and treated at older ages. A clinician can help decide whether you need a sleep history, a review of medicines, a sleep study, or another evaluation.
See when to ask for help and use a simple sleep diary if notes would help you explain the pattern.
A few supportive habits
A fairly regular wake time, daylight and activity during the day, and a comfortable sleep environment can support sleep. Make changes that fit your health and daily life. If you have a persistent sleep problem, habits alone may not address its cause.
