39% of adults are receiving less than the recommended 7 hours.
The amount of sleep we need is dependent of the individual and our
age. It’s best to plan your sleep so that you are able to wake in time
without an alarm clock.

Sleepiness arrives in relation to the amount of time we are awake.  It
is also controlled by our biological (circadian) clock which makes
humans alert while it is light outside and sleepy by the dark of the
The “clock” runs a full day cycle making 2-4am and 1-3pm the times
when we are the most sleep.
The biological clock is also responsible for regulating many body
functions depending on the time of night or day.

REM or Rapid-eye movement and NREM or non-rapid eye movement switch
every 90minutes during a normal night’s sleep.  This process is called
sleep architecture.
75% of our sleep cycle is NREM:
NREM has four stages.
As we linger between sleep and wakefulness we are in stage 1.
In stage two our cognizance of our surroundings falls away.  Also,
body temperature falls.
The deepest part of sleep makes up stages 3 and 4.  At this point, we
enter a restorative sleep.  We re-energize, allow hormones for growth
and development to release, blood pressure drops and our breathing
becomes slower.

REM takes up the other 25% of sleep:
an hour and a half after the onset of sleep, we experience REM.  Our
brain is active at this time and dreams occur.  Our bodies relax and
breathing and heart rate may fluctuate.
Some research suggests that memory is consolidated during this part of sleep.
According to a 2002 poll in America, 74% of adults have sleeping
problems a few times in any given week.
If during the day you feel tired, you should consider making time for
more sleep.

related.  These accidents make up 1500 deaths.
