Understanding the Changes in Sleep Architecture in Seniors
As we age, our sleep cycles naturally become more erratic and less restful due to changes in our body and mind. By the time we reach our senior years, we are likely to experience significant changes in our sleep architecture, especially when compared to younger stages in life. In this article, we will discuss the changes in sleep architecture in seniors and how this affects their overall health and well-being.
One of the primary changes that seniors experience is a decrease in total sleep time. Whereas younger adults generally get between seven and eight hours of sleep per night, seniors may only get between five and six hours. Seniors are also more prone to early awakenings, commonly occurring at least two hours before their usual waking time. As a result, seniors are not able to get the quality rest that they need to feel on top of their game.
Finally, seniors are more likely to spend a greater portion of their sleep time in lighter sleep stages. This means that seniors spend a larger share of their time in non-REM sleep stages, such as stages 1 and 2. As a result, seniors may not receive as much of the rest that occurs in deeper stages of sleep, such as REM sleep. Since REM sleep is the most restorative and restful stage of sleep, this could lead to seniors feeling more tired and fatigued during their waking hours.
Effects on Health and Well-Being
Unsurprisingly, the changes in sleep architecture for seniors can significantly impact their overall health and well-being. Older adults have an increased risk of cognitive decline due to a lack of restorative sleep, which can lead to issues with memory and learning. This is particularly concerning in particular for seniors who already suffer from age-related illnesses.
With less sleep, seniors are also more prone to developing a variety of chronic illnesses, such as hypertension, obesity, cardiovascular disease, and type 2 diabetes. Since lack of sleep has a direct impact on the body’s metabolism, it can disrupt the body’s ability to regulate blood sugar levels and manage weight. Furthermore, seniors become more susceptible to injuries due to fatigue, which affects their ability to stay active.
Strategies to Improve Sleep Quality
Depending on the individual, seniors may find different strategies more or less effective in helping them improve their sleep quality. However, there are a few techniques to help seniors reset their circadian rhythm, such as:
- Limiting daytime naps to 20 minutes
- Setting and following consistent bedtime and wake times
- Adding light therapy for use in the morning
- Considering and consulting on medication with their doctor
- Limiting caffeine intake in the afternoon and evening
- Avoiding stimulating activities before bedtime
It is important for seniors to talk to their doctor to discuss sleep issues and to identify other potential triggers. With the right treatment and lifestyle changes, it is possible for seniors to improve their sleep architecture and thereby, their overall health and well-being.
Conclusion
Changes in sleep architecture are a natural part of aging, and seniors typically struggle to get the same amount and quality of sleep as younger adults. As a result, seniors have an increased risk of developing chronic illnesses and cognitive decline. However, with the right strategies, seniors can take control of their sleep and improve their overall health.
