Sleep is a state of an inactive body during a series of hours, while the mind
is still active. During sleep, we usually pass through four stages of sleep.
The NREM (non-rapid eye movement) stages have been divided into three sub stages,
then the REM (rapid eye movement). The first stage of NREM is the lightest
stage of sleep, in which people can be easily awoken. The second stage of NREM
is when sleep is absolutely acquired. This is the stage is where forty to fifty
percent of sleep is consumed.  The third
stage of NREM is acknowledged as the deep sleep stage. It’s commonly referred
to as the Delta stage of sleep. The final stage of a sleep cycle is REM. Sleep disorders
and dreams can take place during this stage. This stage is also recognized by
an increase of the heart and respiration rates. When, the necessary amount of sleep
is obtained these four stages of sleep are cycled. Each stage can last from
ninety to one hundred and twenty minutes. The body needs sleep in order to
properly function.

revitalizes what is lost in the body while we are awake. Sleep provides an
opportunity for the body to restore its chemical balance. Sleep helps to
improve memory, promote health, and prevent disease. When our immune systems
encounter foreign invaders, (viruses and bacteria) inflammation is a defense
mechanism in order to repair tissues. However, Inflammation is linked to heart
disease, stroke, diabetes, arthritis, and premature aging. Research indicates
that people who get less sleep six or fewer hours a night have higher blood
levels of inflammatory proteins than those who get more. The C-reactive
protein, which is associated with heart attack risk, was higher in people who
got six or fewer hours of sleep a night. “Sleep can definitely reduce
levels of stress, and with that people can have better control of their blood
pressure,” Dr. Jean says. “It’s also believed that sleep effects
cholesterol levels, which plays a significant role in heart disease. Getting a
good night’s sleep won’t grant you immunity from disease. But, study after
study has found a link between insufficient sleep and some serious health
problems, such as heart disease, heart attacks, diabetes, and obesity. The most
important role of sleep is for learning and memory. Synapses are where memories
are stored. More synapses are formed when a person receives an appropriate
amount of sleep versus a person that is sleep deprived.
