How common is insomnia?

Insomnia, along with sleep apnea, restless legs syndrome (RLS) and narcolepsy, are the most commonly diagnosed sleep disorders in people seeking treatment in sleep clinics. Insomnia is defined as difficulty falling asleep or staying asleep every night or most nights despite an adequate opportunity to sleep. Insomnia lasting from a single night to a few weeks is referred to as transient or short-term. If it lasts longer than a month, it's referred to as chronic insomnia. More than a third of American adults experience insomnia, and women are nearly twice as likely to suffer from insomnia as men.
