Insomnia is a sleep disorder that regularly affects millions of people worldwide. Someone with insomnia finds it difficult to fall asleep or stay asleep.

According to the Centers for Disease Control and Prevention (CDC)Trusted Source, adults need at least 7–9 hours of sleep in every 24-hour period, depending on their age.

Research shows that around 25% of people in the United States experience insomnia each year, but around 75% of these people do not develop a long-term problem.
