What is the Circadian Rhythm and how does it affect Seniors?

The circadian rhythm is your body's natural 24-hour internal clock that regulates sleep-wake cycles and other physiological processes. In seniors, this rhythm tends to shift earlier, a phenomenon known as advanced sleep phase syndrome. This results in earlier bedtimes and waking times. Additionally, the circadian signals that promote sleep and wakefulness can weaken with age, leading to more fragmented sleep, increased nighttime awakenings, and daytime fatigue. These changes can impact a senior's overall health and quality of life.
