Sleep is essential for proper functioning of every individual, regardless of age. However, eight hours of uninterrupted and undisturbed sleep is exceptionally more important in elderly due to following reasons.

  • Sleep is believed to be reduced as a normal process and component of aging. This is true for normal elderly too, who don’t have any organic disease process. Both quality and duration of sleep is altered and marked reduced with advancing age. In normal elderly, following changes are seen in the normal pattern of sleep:
  1. Increase time to fall asleep after lying in bed.
  2. Frequent awakening accompanied by increase time taken to fall asleep again as opposed to a normal young adult who requires minutes to fall asleep again.

 

  • Loss of NREM pattern of sleep, Non Rapid Eye Movement is an important component of normal sleep rhythm. Actual relaxation attributed to sleeping is achieved in NREM sleep as it is only during this phase that the brain shut down its processes completely (obviously all processes other than those that are required for life like breathing). Loss of NREM leads to subjective feeling of giddiness and incomplete relaxation, one of the most important complaint elderly have with their sleep.

 

  • Early awakening in the morning which cannot be attributed to any cause. Overall sleep duration, quality and depth is reduced naturally in elderly.

  • Loss of tone in respiratory muscles leading to collapse: With advancing age, all muscles get relaxed and laxed, same is seen in respiratory muscles that loses their tone. In day hours, when people are wide awake and in sitting or standing posture, voluntary brain efforts and body postures don’t let the relaxed muscle to make any noticeable difference in breathing pattern, but at night, when person is sleeping, weight of gastric contents further push upon lungs and further decreases the tone of respiratory muscles.

In young healthy adult, chronic sleep deprivation affects cognitive thinking and problem solving capabilities. However, in young adults, sleep deprivation is normally short term and symptoms resolves by its own without leaving any permanent sequelae. However, in elderly symptoms remain hidden until permanent changes are seen in brain functioning. Sound sleep is required to function properly especially cognition and intellect is greatly affected by poor sleep.
