Insomnia has been around as long as sleep has. Some even believe that
William Shakespeare was an insomniac, writing as vividly as he did about
sleeplessness, tossing and turning, and sleepwalking in plays like
Hamlet and Macbeth. Today, old Will has millions of fellow
The 2007 Sleep in America Survey from the National Sleep Foundation found
that 67% of women say they frequently experience a sleep problem.
The 2005 Sleep in America poll found that 35% of adults experience insomnia
One option today's insomniacs have that Shakespeare didn't, of course, is
the sleeping pill. Over the last 10 to 15 years, the market has been inundated
with new and improved sleep medications -- ones that don’t come with the same
degree of hangovers, side effects, and risk of dependency that previous sleep
But that doesn’t mean they’re risk-free, or ideal for everyone who has
problems getting a solid forty winks.
The older classes of sleep medications, particularly the benzodiazepines --
think Valium and Xanax -- do more than just help you sleep. They affect
how you sleep, altering your actual "sleep architecture," says Donna
Arand, PhD, clinical director of the Kettering Sleep Disorders Center in
"They tend to decrease the amount of time spent in certain stages of sleep,
particularly stages three and four (the deepest, most restful stages of
sleep)," says Arand, who serves on the boards of the American Academy of Sleep
Medicine and the American Insomnia Association. "People also complained of
hangover effects from these medications." That's because they tend to have a
longer "half-life," which is the length of time the drug stays in your
Non-benzodiazepine hypnotics like Ambien, Ambien CR, Rozerem, Sonata, and
Lunesta, however, share key advantages over previous generations of sleep
They have a relatively short half-life, so you won't wake up groggy the
next day. "There are minimal reports of 'hangover' effects with these new
drugs," says Arand.
They are less likely than the older sleeping pills to cause addiction,
withdrawal symptoms, or a buildup of tolerance (when you require more and more
drug to have the same effect).
Why? The newer medications act only on specific receptors in your brain that
are focused on sleep, while older groups of drugs have a more generalized
effect on multiple brain receptors. "These new drugs are among the safest
medications in medicine," says Thomas Roth, MD, Director of the Sleep Disorders
and Research Center at Henry Ford Health System in Detroit.
