Sleep deprivation can kill you

Many people all over the world suffer from sleep-related breathing disorders. Many of these
patients stop breathing hundreds of times every night. This is why the evaluation and treatment of
patients with the obstructive sleep apnea syndrome ultimately play an important part of critical care
medicine.
In 1900, adults in the United States slept an average of nine hours per night. In 2000, adults slept an
average of just seven hours per night. We have not evolved to need less sleep, but we are getting
less sleep. In past centuries, our sleep/wake cycle was closely linked to the rotation of the earth. We
slept when it was dark and we awoke and worked when it was light. However, with the
development and widespread availability of artificial light, we have prolonged our waking hours.
Stimulants such as caffeine have also contributed to longer periods of wakefulness.
Deep refreshing sleep is essential for feeling rested and well. If you are not getting enough sleep,
this could make you feel very sad and could contribute to significant relationship difficulties.
You undoubtedly are judged at work on a regular basis. Not getting enough sleep will affect your
job performance and could contribute to being passed over for promotion or loss of your job.
Obesity is a major problem in the United States. While poor eating habits certainly contribute, lack
of sleep is also likely a factor. The hormone leptin has a significant impact on appetite for food.
Increased levels suppress appetite. There is evidence that not getting enough sleep lowers your
leptin levels. This results in an increase in appetite and weight gain.
Sleep is essential for our well-being. As we get older, good sleep is often harder to come by. With
the aging process, we experience less of the deep sleep known as slow-wave sleep. Combine this
with medical problems such as arthritis, reflux, heart and lung disease and you have a recipe for
ongoing sleep problems.
