2a11212 What Is Insomnia?
Do you have trouble falling asleep? Do you wake up often during the night? Or, maybe you wake up too early in the morning. You may be suffering from insomnia. Talk to your health care provider if it lasts longer than a few weeks and you feel tired most of the time.

What Causes Insomnia?
Some common causes of insomnia are:
  • Medical problems such as pain, depression, medication side effects, or trouble breathing
  • Circadian rhythm disorder, a shift in the body's normal 24-hour activity cycle
  • Lifestyle factors such as a changing sleep schedule, lack of exercise, or too much caffeine
  • Sleep settings such as a poor mattress, noise, or a room that's too hot or too cold
  • Stress such as problems at work, money worries, or family events
