Feeling older than one's actual age may be an indicator of insufficient quality sleep, according to new research. A study conducted by the National Sleep Foundation and published in the journal Sleep revealed that adults who perceived themselves as older than their chronological age frequently reported symptoms of insomnia, inconsistent sleep patterns, and fatigue during the day.
The research involved over 3,100 adults who were asked about their perceived age. Researchers then correlated these responses with various measures of sleep quality, sleep consistency, and daytime functioning. The findings indicated that individuals who felt older than their actual age consistently reported poorer sleep and greater impairment related to sleep compared to those who felt younger or closer to their chronological age.
Furthermore, the study observed that participants who felt older than their age were also more likely to report poorer physical health. Jonathan Alpert, a psychotherapist and author not involved in the study, noted that these findings align with his clinical observations. He stated that individuals often describe feeling exhausted, experiencing mental fog, reduced patience, and a general decrease in motivation and overall functioning, with poor sleep frequently being a significant contributing factor.
Alpert explained that inadequate sleep can intensify the perceived difficulty of daily responsibilities and hinder a person's ability to concentrate, manage stress, and maintain typical energy levels. Over time, these challenges can contribute to a sense of premature aging. He suggested that many people mistakenly attribute feeling older to the inevitable process of aging, when in fact, chronic sleep deprivation may be the primary issue.
He advised examining sleep habits before concluding that fatigue and low energy are solely consequences of aging. The study's findings serve as a reminder that fatigue should not automatically be attributed to getting older.
However, the study has certain limitations. It relied on self-reported data, meaning participants provided information about both their perceived age and sleep habits. Additionally, its observational design does not allow for definitive conclusions on whether poor sleep influences perceived age or vice versa.
