It is impossible to overestimate
the importance of sleep in establishing a well balanced
life. We spend about 8 hours a day, 56 hours per week,
240 hours per month, and 2920 hours per year sleeping.
Studies show that insufficient sleep affects about 70
million people in the USA alone. Women report
insomnia symptoms nearly twice as often as
men.
Insomnia, a problem
which becomes more frequent with age, is a common and
distressing difficulty in falling asleep, going back to
sleep or waking too early where the wake period is
greater than 30 minutes.
Although there are several
different degrees of insomnia, about three types of
insomnia have been clearly identified: transient, acute,
and chronic. Transient insomnia lasts from days to weeks,
acute insomnia is the inability to consistently sleep
well for a period of between three weeks to six months
and chronic insomnia can last for years at a
time.
Cause of
Insomnia
Often insomnia is a symptom of other
problems in life such as illness, death of a family member
or friend, financial stress, or work and relationship
issues. Some medical conditions may cause insomnia,
particularly pain, chronic respiratory problems, or other
sleep disorders. Medications such as blood pressure tablets
or asthma medication, as well as substances like caffeine,
nicotine and alcohol, may trigger insomnia or make it
worse.
Psychiatric conditions such as depression and anxiety are
common causes of insomnia and sometimes may also cause
insomnia.
Certain neurological disorders,
brain lesions, or a history of traumatic brain injury,
medical conditions such as hyperthyroidism and Wilson's
syndrome, Parasomnia, which includes a number of
disruptive sleep events including nightmares,
sleepwalking, violent behavior while sleeping, and REM
behavior disorder, can all cause sleep
problems.
Sometimes even the
use of prescription sleep aids are a problems as when over
used these drugs can cause what is know as rebound
insomnia.
Shift workers are particularly at risk of
insomnia as they are trying to sleep when their brain is
trying to be awake and at night they are trying to stay
awake when brain and body want to go to
sleep.
The Impact of
Insomnia
The Impact of Insomnia on daily living can
be substantial, sufferers report lack of energy,
irritability, poor performance at work, memory difficulties
and concentration problems. One study found twice as many
fatigue related automobile accidents in individuals with
insomnia compared with good sleepers. Insomnia is a risk
factor for the onset of depression and can significantly
affect your quality of life. There is also some evidence to
suggest that the stress response found in insomniacs is a
risk factor for heart disease and diabetes.
Treatment of
Insomnia
For a long time, doctors were
taught that insomnia was a symptom, not a disease,
however, new evidence is beginning to suggest insomnia
may not simply be a symptom of other conditions, but
rather, may be a disorder in its own right.
The main goal of any treatment for
insomnia is to break the vicious cycle that keeps the
insomnia going. To achieve this, a variety of therapies
have been tried but many in themselves can create other
problems which can often create adverse cycles of their
own.
Hypnotic medications are effective
in the short term treatment of insomnia but their effects
wear off over time due to tolerance. The use of
benzodiazepines and antidepressants in the treatment of
insomnia can lead to physical dependence, withdrawal of
these medications may induce rebound insomnia and
actually further complicate matters in the long
term.
Alternative therapies are popular
with herbs such as valerian, chamomile, lavender, hops,
and passion flower being particular favorites. Hypnotism
can be successful but this too is often only a short term
measure.
New technology using non
transdermal patches which stimulate acupressure points is
perhaps the most promising. At this stage the only one on
the market is Silent
Nights produced by network marketing
company, Lifewave. Clinical studies show that this
technique improves the quality of sleep by balancing
energy flows which results in relaxation and better sleep
patterns.
