Insomnia - overview
Insomnia is trouble falling asleep, staying asleep through the night, or waking up too early in the morning.
Episodes of insomnia may come and go or be long-lasting.
The quality of your sleep is as important as how much sleep you get.
Sleep disorder - insomnia; Sleep issues; Difficulty falling asleep; Sleep hygiene - insomnia
Sleep habits we learned as children may affect our sleep behaviors as adults. Poor sleep or lifestyle habits that may cause insomnia or make it worse include:
- Going to bed at a different time each night
- Daytime napping
- Poor sleeping environment, such as too much noise or light
- Spending too much time in bed while awake
- Working evenings or night shifts
- Not getting enough exercise
- Using the television, computer, or a mobile device in bed
The use of some medicines and drugs may also affect sleep, including:
- Alcohol or other drugs
- Heavy smoking
- Too much caffeine throughout the day or drinking caffeine late in the day
- Getting used to certain types of sleep medicines
- Some cold medicines and diet pills
- Other medicines, herbs, or supplements
Physical, social, and mental health issues can affect sleep patterns, including:
- Bipolar disorder.
- Feeling sad or depressed. (Often, insomnia is the symptom that causes people with depression to seek medical help.)
- Stress and anxiety, whether it is short-term or long-term. For some people, the stress caused by insomnia makes it even harder to fall asleep.
Health problems may also lead to problems sleeping and insomnia:
- Physical pain or discomfort.
- Waking up at night to use the bathroom, common in men with enlarged prostate
- Sleep apnea
With age, sleep patterns tend to change. Many people find that aging causes them to have a harder time falling asleep, and that they wake up more often.
The most common complaints or symptoms in people with insomnia are:
- Trouble falling asleep on most nights
- Feeling tired during the day or falling asleep during the day
- Not feeling refreshed when you wake up
- Waking up several times during sleep
People who have insomnia are sometimes consumed by the thought of getting enough sleep. But the more they try to sleep, the more frustrated and upset they get, and the harder sleep becomes.
Lack of restful sleep can:
- Make you tired and unfocused, so it is hard to do daily activities.
- Put you at risk for auto accidents. If you are driving and feel sleepy, pull over and take a break.
Exams and Tests
Your health care provider will do a physical exam and ask about your current medications, drug use, and medical history. Usually, these are the only methods needed to diagnose insomnia.
Not getting 8 hours of sleep every night does not mean your health is at risk. Different people have different sleep needs. Some people do fine on 6 hours of sleep a night. Others only do well if they get 10 to 11 hours of sleep a night.
Treatment often begins by reviewing any drugs or health problems that may be causing or worsen insomnia, such as:
- Enlarged prostate gland, causing men to wake up at night
- Pain or discomfort from muscle, joint, or nerve disorders
You should also think about lifestyle and sleep habits that may affect your sleep. This is called sleep hygiene. Making some changes in your sleep habits may improve or solve your insomnia.
Some people may need medicines to help with sleep for a short period of time. But in the long run, making changes in your lifestyle and sleep habits is the best treatment for problems with falling and staying asleep.
- Most over-the-counter (OTC) sleeping pills contain antihistamines. These medicines are commonly used to treat allergies. Your body quickly becomes used to them.
- Sleep medicines called hypnotics can be prescribed by your provider to help reduce the time it takes you to fall asleep. Most of these can become habit-forming.
- Medicines used to treat anxiety or depression can also help with sleep
Different methods of talk therapy may help you gain control over anxiety or depression.
Most people are able to sleep by practicing good sleep hygiene.
