A recent study suggests that feeling older than one’s actual age may be linked to poor sleep. The research, which included more than 3,100 adults, examined how subjective age, or the age a person feels, relates to sleep health.
Researchers looked at several measures of sleep, including insomnia severity, sleep regularity, and daytime impairment. They found that people who felt older than their chronological age reported more insomnia symptoms, less consistent sleep schedules, and greater sleep-related problems during the day.
The study included adults with an average age of 42.8. Participants completed an online survey that asked about their demographics, subjective age, and sleep patterns. The researchers also assessed depression, anxiety, and self-reported physical health.
The link between feeling older and poor sleep remained even after accounting for factors such as actual age, sex, race, depression, and anxiety. This suggests the effect is not simply explained by being older or having mental health issues.
Sleep as a pathway
The researchers also explored whether sleep might explain the connection between feeling older and worse physical health. They found that a higher age discrepancy was linked to increased insomnia, greater sleep-related impairment, and lower sleep regularity. Each of those sleep variables was then tied to worse self-reported physical health.
This indicates that sleep may be one of the ways feeling older affects the body. The relationship likely works in both directions. Poor sleep may also make a person feel older, as chronic lack of rest can lead to body aches, low mood, and low energy.
Practical implications
The study points to sleep regularity as a key factor. Going to bed and waking up at the same time each day, even on weekends, may help. The research also challenges the common belief that poor sleep is a normal part of aging. Insomnia symptoms are treatable, and addressing them early may have positive effects on both physical health and how old a person feels.
Challenging negative perceptions about aging may also help. The study suggests that assuming feeling older is inevitable could worsen sleep. Recognizing that how one feels is not fixed may be part of the solution.
Daily habits such as consistent exercise, stress management, and morning light exposure support deep and regular sleep. These habits can reinforce each other, creating a feedback loop that benefits both sleep and overall well-being.
The takeaway is that the age a person feels may be a signal about how well they are sleeping. Feeling older than one’s actual age is tied to worse insomnia, lower sleep regularity, and greater daytime impairment, independent of actual age, depression, and anxiety. Addressing sleep quality early, rather than accepting it as an inevitable part of getting older, may help shift both how a person feels and how their body holds up over time.
