Insmonia


Insomnia is the perception of poor-quality sleep, including the inability to fall asleep or stay asleep. Because people differ in their need for sleep, there are no fixed criteria that define insomnia. Insomnia is very common and occurs in 30% to 50% of the general population. Approximately 10% of the population may suffer from chronic (long-standing) insomnia. Sleep onset insomnia is characterized as occurring at the beginning of the desired sleep time and lasting for greater than 30 minutes. Sleep maintenance insomnia is when individuals fall asleep, but awaken periodically or for lengthy periods during the night, increasing the “wake after sleep onset.”
