T he causes of sleep deprivation are found in di fferent parts of the human anatomy.
The causes of sleep deprivation are very active in the brain.
The loss of neurons in the brain cause shifts in sleep cycles.
The 24 hour clock that keeps humans up to pace with night and day is disrupted.
"Communication technologies are often light-emitti ng, which can suppress the sleep promoting hormone melatonin and make it harder to go to sleep at night." (Richardson, 1899 ) .
The body reacts in harmful ways to sleep deprivation.
Dr. Daniel Cohen, a neurology professor at Harvard Medical School said chronic sleep loss has the same effects as pulling an all- nighter.
Dr. Cohen says, "After sleeping fewer than six hours per night for two to three weeks, people may drive as poorly as someone who has stayed up for 24 hours straight." (Newsweek, 75 ) .
Age is a factor that contributes greatly to the loss of sleep in an average human being.
As a person gets older they go into the early stages of sleep cycles, causing them to lose more sleep or not sleep at all during the night.
Males over 40 are more common to have SDB (sleep-disordered breathing), caused by inspiratory flow limitation, without any sympt oms or health consequences. (Richardson, 1889 ) .
Skin lesions occur when too much sleep is lost.
In 1989, a seminal study demonstrated that rats that were subjected to total sleep deprivation developed skin lesions, experienced weight loss in spite of increased food intake, developed bacterial infections, and died within 2 to 3 weeks ( Rechtschaf fen et al., 1989).
Thermoregulation controls our body temperature while we sleep.
Sleep deprivation disrupts our body's attempts at lowering our temperature during the night so we can sleep comfortably.
"At night there is a gradual decline in body temperature rhythm, and an increase in heat loss, all which promote sleep onset and maintenance, as wel l as EEG slow-wave activity." ( Lawrence, 3 ) .
Aches and pains begin with the loss of sleep and persist if a person does not improve their sleep schedule to accommodate his or her body's needs.
Diseases cause and are a repercussion of sleep deprivation.
Sleep apnea is a common cause and effect of sleep deprivation.
Sleep apnea often goes undiagnosed because doctors don't notice it during routine visits since it only happens during sleep.
Insomnia is common in ma ny Americans, contributing to sleep deprivation.
"Insomnia may be primary or secondary to other sleep problems and may be associated wit h a number of co-morbidities". ( Klasson ) .
It is suggested that 40 to 70 million Americans, which reflect on 20% of the population, are affected by insomnia or other c hronic sleep problems. ( Klasson ).
