Medical scientists at the University of Arizona have determined that vision deterioration with aging, exposure to sunlight and physical activity form the major triggers to poor quality sleep and early rising in people approaching old age.

The report offers that individuals suffering distorted sleep patterns must make conscious efforts that condition their immediate environment to conform to necessary sleep triggers that set up the body sleep clock.

These cues, also known as “time givers,” assist the brain in sensing its position within the 24-hour circadian cycle. However, as we grow older, the wiring of the brain may become less efficient in registering and responding to these cues, the scientists declared in a report studied by The Oracle Today.

The study showed that shift in our sleep patterns, with the tendency to wake up earlier in the morning becoming more prominent as people get older, explaining that natural aging process brings about changes in the way our bodies approach rest and the amount of sleep required.

According to the Director of the Center for Sleep and Circadian Science at the University of Arizona, Dr. Sairam Parthasarathy, who has conducted research to understand the underlying reasons behind this shift, the one crucial aspect involves the brain’s responsiveness to external cues, such as sunlight, social cues, and physical activity, which help us determine the time of day.

“Furthermore, vision changes that commonly accompany aging play a significant role in this phenomenon.”

Dr. Parthasarathy explains that age-related vision deterioration reduces the intensity of light stimulation that our brain receives. Light exposure is a crucial factor in setting and maintaining our circadian clock, which regulates our sleep-wake cycle. With diminished light simulation, older individuals may find it more challenging to keep their internal clocks synchronized with the external world.

These findings, according to the report, offer valuable insights into the relationship between aging, sleep patterns, and circadian rhythms.

“While waking up earlier may be a natural consequence of the aging process, it is essential to note that individual variations exist. Not everyone will experience this shift to the same extent or at the same age.

“Understanding the biological changes associated with aging can help us adapt our routines to promote better sleep hygiene. By acknowledging the alterations in our internal clock and adjusting our habits accordingly, such as maintaining a consistent sleep schedule and optimizing our sleep environment, we can mitigate the impact of these changes and promote restful sleep at any age,” the report offered.
