Sleep quality often declines as people age due to physiological changes and medical factors, geriatric experts said.
Understanding these shifts is critical because chronic sleep disruption in older adults can impact overall health and cognitive function. Experts said that identifying the root causes of insomnia allows patients to pursue evidence-based strategies without relying on sedative medications.
In a recent discussion on the Aging Forward podcast, host Kristen Meinzer and geriatrician Dr. Melissa Bogin examined the reasons why falling asleep becomes more difficult over time [1]. The conversation focused on the normal age-related changes in sleep patterns and how these shifts differ from clinical insomnia [1].
Physiological changes in the brain and body often lead to fragmented sleep or a decreased ability to maintain deep sleep stages [1]. These medical factors can be compounded by health conditions common in older populations, making a structured approach to sleep hygiene essential [2, 3].
While older adults face these challenges, the needs for sleep vary significantly across the lifespan. For comparison, teenagers often require around 10 hours [2] of uninterrupted sleep to function optimally. As the body ages, the circadian rhythm, the internal clock that regulates sleep and wake cycles, can shift, often leading to earlier wake times and daytime drowsiness [1, 2].
Dr. Bogin and Meinzer said non-drug strategies can improve sleep quality [1]. These evidence-based methods focus on environmental adjustments, and behavioral changes to align the body's internal clock with desired sleep schedules [1]. By avoiding medication as a first resort, older adults can address the underlying causes of their sleep issues while avoiding potential side effects associated with sleep aids [1, 3].
Experts said that while some decline in sleep efficiency is a normal part of aging, severe insomnia is not an inevitable part of getting older [1]. Consistent routines and targeted interventions can help maintain a higher quality of life for aging populations [1, 3].
“Sleep quality often declines as people age due to physiological changes and medical factors.”
The shift toward non-medication interventions for geriatric sleep disorders reflects a broader medical effort to reduce polypharmacy in older adults. By prioritizing behavioral changes and circadian alignment, clinicians aim to improve sleep quality while minimizing the risks of falls and cognitive impairment often linked to sedative use in the elderly.
