Napping Provides Cognitive Benefits – Improves Mental Health
Napping provides cognitive benefits, especially for the elderly. Sleep is important for physical, mental, and spiritual health and wellbeing. For optimal benefits
adults need between seven and eight hours of sleep.
There are many problems associated with inadequate sleep. Lack of sleep can cause difficulties with concentration, fatigue, lack of energy, lethargy, depressed immune system, illicit drug use, absenteeism, memory lapses; and other problems including motor vehicle accidents, and workplace accidents (NIH.Gov).
Sleep occurs as a result of natural activities in the brain. There are two states of sleep – rapid eye movement (REM) and non-rapid movement NREM). Non-REM sleep is made up of stages 1, 2, 3 & 4. A complete cycle of sleep progresses through each of these stages . Each of these stages can last 5 to 15 minutes. Once the cycle is completed REM sleep is achieved, and the cycle is repeated.
Stage 1: The duration of this stage is five to ten minutes. During this stage there is a decrease in activity between wakefulness and stage 1 sleep. One is easily awakened during this stage, but once awakened the individual may feel that he or she has not slept.
Stage 2: This is the preparation stage for the body to enter into deep sleep. During this stage there are changes in the heart rate (slowing) and temperature (lowers).
Stages 3 & 4: These are the stages in which the individual experiences deep sleep. When sleep is disturbed during these stages an individual may experience some disorientation for a short period of time.
After the age of 60 years, individuals have less deep sleep and awaken often which results in an average of 2 hours less sleep each night. Contrary to previous assumptions that older adults require less sleep than younger adults, research confirms that all adults require between seven and eight hours of sleep each night for optimal functioning.
A study conducted by researchers at Weill Cornell Medical College looked at the benefits of napping during the day to compensate for lack of sleep during the night. They also looked at the possible disruption of the sleep cycle due to daytime napping. Findings from the study indicated that napping increased total sleep time in older individuals “without producing daytime drowsiness—but also provides measurable cognitive benefits.”
