Types of Insomnia
- Primary insomnia: Primary insomnia means that a person is having sleep problems that are not directly associated with any other health condition or problem.
- Secondary insomnia: Secondary insomnia means that a person is having sleep problems because of something else, such as a health condition (like asthma, depression, arthritis, cancer, or heartburn); pain; medication they are taking; or a substance they are using (like alcohol).
Acute vs. Chronic Insomnia
Insomnia also varies in how long it lasts and how often it occurs. It can be short-term (acute insomnia) or can last a long time (chronic insomnia). It can also come and go, with periods of time when a person has no sleep problems. Acute insomnia can last from one night to a few weeks. Insomnia is called chronic when a person has insomnia at least three nights a week for three months or longer.
Causes of Insomnia
Causes of acute insomnia can include:
- Significant life stress (job loss or change, death of a loved one, divorce, moving)
- Emotional or physical discomfort
- Environmental factors like noise, light, or extreme temperatures (hot or cold) that interfere with sleep
- Some medications (for example those used to treat colds, allergies, depression, high blood pressure, and asthma) may interfere with sleep
- Interferences in normal sleep schedule (jet lag or switching from a day to night shift, for example)
Causes of chronic insomnia include:
Symptoms of Insomnia
Symptoms of insomnia can include:
- Sleepiness during the day
- General tiredness
- Problems with concentration or memory
If you think you have insomnia, talk to your health care provider. An evaluation may include a physical exam, a medical history, and a sleep history. You may be asked to keep a sleep diary for a week or two, keeping track of your sleep patterns and how you feel during the day. Your health care provider may want to interview your bed partner about the quantity and quality of your sleep. In some cases, you may be referred to a sleep center for special tests.
Treatment for Insomnia
Acute insomnia may not require treatment. Mild insomnia often can be prevented or cured by practicing good sleep habits (see below). If your insomnia makes it hard for you to function during the day because you are sleepy and tired, your health care provider may prescribe sleeping pills for a limited time. Rapid onset, short-acting drugs can help you avoid effects such as drowsiness the following day. Avoid using over-the-counter sleeping pills for insomnia, because they may have undesired side effects and tend to lose their effectiveness over time.
Treatment for chronic insomnia includes first treating any underlying conditions or health problems that are causing the insomnia. If insomnia continues, your health care provider may suggest behavioral therapy. Behavioral approaches help you to change behaviors that may worsen insomnia and to learn new behaviors to promote sleep. Techniques such as relaxation exercises, sleep restriction therapy, and reconditioning may be useful.
Good Sleep Habits for Beating Insomnia
Good sleep habits, also called sleep hygiene, can help you get a good night's sleep and beat insomnia. Here are some tips:
- Try to go to sleep at the same time each night and get up at the same time each morning. Try not to take naps during the day, because naps may make you less sleepy at night.
Avoid prolonged use of phones or reading devices ("e-books") that give off light before bed. This can make it harder to fall asleep.
- Avoid caffeine, nicotine, and alcohol late in the day. Caffeine and nicotine are stimulants and can keep you from falling asleep. Alcohol can cause waking in the night and interferes with sleep quality.
- Get regular exercise. Try not to exercise close to bedtime, because it may stimulate you and make it hard to fall asleep. Experts suggest not exercising for at least three to four hours before the time you go to sleep.
- Don't eat a heavy meal late in the day. A light snack before bedtime, however, may help you sleep.
- Make your bedroom comfortable. Be sure that it is dark, quiet, and not too warm or too cold. If light is a problem, try a sleeping mask. If noise is a problem, try earplugs, a fan, or a "white noise" machine to cover up the sounds.
- Follow a routine to help you relax before sleep. Read a book, listen to music, or take a bath.
- Avoid using your bed for anything other than sleep or sex.
- If you can't fall asleep and don't feel drowsy, get up and read or do something that is not overly stimulating until you feel sleepy.
- If you find yourself lying awake worrying about things, try making a to-do list before you go to bed. This may help you to not focus on those worries overnight.
