Sleep

We spend 25 years of our lives sleeping, lets do it right.

Lack of Sleep and Disorders

Lack of awareness and cognitive thinking is only one of the many side effects of improper sleep. “Long-term effects of sleep deprivation and sleep disorders have been associated with a wide range of deleterious health consequences including an increased risk of hypertension, diabetes, obesity, depression, heart attack, and stroke.” (Colten, R, (U.S.), Altevogt, & M., 2006) Improper sleep is not only measured in length, it is can also be seen in lack of sleep quality. Sleep can be broken in two main phases, rapid-eye-movement (REM) sleep and non-rapid-eye-movement (NREM) sleep. (Harvard Medical School, 2007) If either one of these phases are inadequately met, the sleeper faces improper sleep. Experts believe REM sleep is when dreams occur. During this time humans are unable to move their limbs. NREM sleep can be broken down into three sub-phases. NREM 1 is the lightest stage, while NREM 3 is the deepest. While in the NREM phase our eyes do not move. Scientists can measure these sleep phases using an Electroencephalogram (EEG). This is most often done by having a person spend a night, and possibly the following day, at a sleep clinic. The patient is hooked up to a EEG and monitored through video cameras and movement sensors. At the sleep clinic, the person is monitored for length of sleep, quality of sleep, amount of time spent in each of the phases of sleep, and possibly for the quality of their naps the following day.

Exhausted Man

Sleep disorders can cause improper sleep. “50-70 million US adults have a sleep disorder.”(American Sleep Association, n.d.) There are many types of sleep disorders some of the most common being insomnia, sleep apnea, restless leg syndrome (RLS). There is a wide range of study around sleeping disorders, as those affected can range from young to old. While there are many facets to sleep disorders, on going research is providing new information. However, there is a solid base of information that can be used to help sufferers today.
