Insomnia affects millions of individuals, their families, and communities. Sufferers have trouble falling asleep or staying asleep, or they wake up too early and are unable to get back to sleep. People who suffer from insomnia usually wake up feeling tired.
Insomnia happens occasionally to people who are experiencing very stressful life events, consuming too many caffeinated beverages or alcohol, or suffering from pain or other physical discomfort. Once the contributing factors are dealt with, these people will no longer suffer from insomnia.
