Why Sleep Changes as We Age
Before we explore the common missteps, it’s helpful to understand why our sleep patterns shift after 55. Our bodies run on an internal 24-hour clock known as the circadian rhythm. This master clock regulates our sleep-wake cycle, telling us when to feel tired and when to feel alert. As we age, this internal clock can shift. You might notice you feel sleepy earlier in theevening and wake up earlier in the morning. This is a natural change.
Furthermore, the very structure of our sleep changes. We tend to spend less time in the deepest, most restorative stages of sleep and more time in lighter sleep stages. This means we are more easily awakened by noise, light, or discomfort. Conditions like arthritis, the need to use the restroom, or other health concerns can also contribute to interrupted sleep.
Understanding these changes is empowering. It helps us see that challenges with senior sleep are not a personal failing but a biological reality we can work with. By creating a consistent and nurturing environment for sleep, we can support our body’s natural rhythm and significantly improve the quality of our rest, even if the quantity looks a little different than it did at 35.
