As the body ages, the circadian clock begins to change. Individuals in their 50s and 60s can experience changes in their sleeping patterns, which can affect their quality of life.
There are multiple factors at play, including the weakening of the circadian rhythms, which control wake/sleep behaviours. Another factor is that most older adults, especially those in nursing homes, receive inadequate light. In one sample of a nursing home, patients received only 1.6 minutes of bright light exposure per day.
How do you know if you are light deprived?
Due to the changes in circadian rhythms and insufficient bright light exposure, many seniors may experience:
- Sleep fragmentation
- Sleepiness early evening
- Wakefulness in the middle of the night
- Interrupted sleep
- Wandering
How can the 50 plus reset their body clock?
Clinical studies have shown that as we age, we respond favorably to bright light exposure. Depending on the exact nature of the individual's sleep difficulties, he or she may benefit from 30 minutes of light exposure upon waking and another 30 minutes in the afternoon. The amount of time exposed to bright light is different for every individual. To develop a schedule that best meet your needs, you should seek advice from your health professional.
Bright light exposure is not recommended for individuals with a history of cataracts or macular degeneration, or who have undergone corrective laser eye surgery in the past 30 days. |
