Everyone misses out on a good night’s sleep at some point or another. But when adequate sleep becomes a nightly struggle, it drains energy and can drastically affect a person’s health, mood and daily functioning.
People who have difficulty falling asleep and-or staying asleep might be dealing with the sleep disorder called insomnia. Symptoms of insomnia also can include waking up too early in the morning or feeling unrefreshed upon waking. Insomnia is classified as either short-term or chronic, when it lasts at least three nights a week for a month or longer.
Adults generally need seven to eight hours of restorative sleep a night.
