1. What It Isn’t
Maybe you regularly stay out late because you love a good party, and now (surprise!) you’re tired. Or you’re at the office until the wee hours to get ahead at work. Those aren’t examples of insomnia. Insomnia is when you can’t fall asleep, even though you want to, or you can’t stay asleep long enough.
2. Stress
Events like a job loss or the death of a loved one often cause some sleepless nights. Your doctor might call it acute insomnia as long as it goes away on its own within a few nights. Long-term worry, as well as anxiety disorder, panic attacks, and PTSD, can lead to chronic insomnia, which is more serious.
