While the ideal amount of healthy sleep can vary between individuals, studies suggest that in the absence of alarms and artificial lights, the natural sleep duration is typically just over eight hours. However, as people age, sleep patterns change—not because we need less sleep, but because older adults often get less sleep.
Sleep Challenges with Aging
As we grow older, sleep becomes more fragile and is more easily disrupted by factors such as light, noise, and diet. A study found that after the age of 65, 13% of men and 36% of women reported taking over 30 minutes to fall asleep. Several factors may contribute to these changes in sleep, including:
- Reduced exposure to natural light.
- Lack of exercise and mental stimulation.
- Age-related changes such as an aging bladder, leading to frequent nighttime bathroom trips.
Sleep also becomes more shallow, fragmented, and variable in duration, making it harder to get a full night’s rest.
Chronic Pain and Sleep Disruptions
Another factor contributing to sleep difficulties in older adults is chronic pain. People over 50 who suffer from nighttime pain often struggle with sleep disruptions, losing an average of 2.2 hours of sleep per night over 10 nights a month. This sleep loss can lead to excessive daytime sleepiness and affect overall well-being.
The Good News
While sleep patterns do change with age, persistent trouble falling asleep or feeling drowsy during the day is not inevitable. By understanding the factors that contribute to sleep difficulties and taking steps to address them—such as improving sleep hygiene, maintaining an active lifestyle, and managing chronic pain—adults can still enjoy restful, restorative sleep as they age.
