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.
Anyone may have insomnia. As many as 30 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.
