What Are the Signs and Symptoms of Insomnia?

The main symptom of insomnia is trouble falling and/or staying asleep, which leads to lack of sleep. If you have insomnia, you may:
  • Lie awake for a long time before you fall asleep
  • Sleep for only short periods
  • Be awake for much of the night
  • Feel as if you haven't slept at all
  • Wake up too early
The lack of sleep also can cause other symptoms. You may wake up feeling tired or not well-rested, and you may feel tired during the day. You also may have trouble focusing on tasks. Insomnia can cause you to feel anxious, depressed, or irritable.

Insomnia may affect your daily activities and cause serious problems. For example, you may feel drowsy while driving. Driving while sleepy leads to more than 100,000 car crashes each year. In older women, research shows that insomnia raises the risk of falling.

If insomnia is affecting your daily activities, see your doctor. Treatment may help you avoid symptoms and problems related to the condition. Also, poor sleep may be a sign of other health problems. Finding and treating those problems could improve both your health and your sleep.
