When to see a doctor:

If insomnia makes it hard for you to function during the day, see your doctor to determine what might be the cause of your sleep problem and how it can be treated. If your doctor thinks you could have a sleep disorder, you might be referred to a sleep center for special testing.

Common causes of insomnia include:

Stress - Concerns about work, school, health or family, stressful life events can keep your mind active at night, making it difficult to sleep, and may lead to Insomnia.

Anxiety - Everyday anxieties such as post-traumatic stress disorder, may disrupt your asleep. Worrying about being able to go to sleep can make it harder to fall asleep.

Depression - You might either sleep too much or have trouble sleeping if you're depressed.

Caffeine, nicotine and alcohol - Coffee, tea, cola and other caffeine-containing drinks are well-known stimulants. Drinking coffee in the late afternoon and later can keep you from falling asleep at night. Nicotine in tobacco products is another stimulant that can cause insomnia. Alcohol is a sedative that may help you fall asleep, but it prevents deeper stages of sleep and often causes you to awaken in the middle of the night.

Medical conditions - If you have chronic pain, breathing difficulties or a need to urinate frequently, you might develop insomnia.

Change in your environment or work schedule - Travelling or working a late or early shift can disrupt your body's circadian rhythms and your body clock, making it difficult to sleep.

Poor sleep habits - Poor sleep habits include an irregular sleep schedule, stimulating activities before bed, an uncomfortable sleep environment, and use of your bed for activities other than sleep or sex.

Eating too much late in the evening - Having a light snack before bedtime is OK, but eating too much may cause you to feel physically uncomfortable while lying down, making it difficult to get to sleep. Many people also experience heartburn, a backflow of acid and food from the stomach into the esophagus after eating, which may keep you awake

Medications - Many prescription drugs can interfere with sleep, including some antidepressants, heart and blood pressure medications, allergy medications, stimulants (such as Ritalin), and corticosteroids.
