Insomnia Symptoms

People with insomnia experience one or more of the following nighttime symptoms:

• Difficulty falling asleep at night
• Waking up intermittently during the night
• Waking up too early in the morning

The resulting lack of sleep causes them to develop the following daytime symptoms:

• Fatigue or drowsiness
• Anxiety, depression, or irritability
• Difficulty concentrating or memory problems

Long-term insomnia can cause or worsen medical conditions, such as diabetes and high blood pressure. Daytime drowsiness due to insomnia can also cause people to have accidents at home, at work, and while driving.
