Insomnia is the most common sleep complaint. It occurs when you have trouble falling asleep or staying asleep even though you had the opportunity to get a full night of sleep. The causes, symptoms and severity of insomnia vary from person to person. Insomnia may include:
Insomnia involves both a sleep disturbance and daytime symptoms. The effects of insomnia can impact nearly every aspect of your life. Studies show that insomnia negatively affects work performance, impairs decision-making and can damage relationships. In most cases, people with insomnia report a worse overall quality of life.
Everyone has the occasional night of poor sleep. In many cases this is due to staying up too late or waking up too early. This does not mean you have insomnia, it means you didn’t get enough sleep.
As many as 30 to 35 percent of adults complain of insomnia. It is more common in groups such as older adults, women, people under stress and people with certain medical and mental health problems such as depression.
