Is it normal to not sleep some nights?
Depends.It depends
Yes, an occasional sleepless night happens to lots of people, especially during stress or when your routine is off. If it’s happening often or leaving you struggling during the day, it’s worth looking into.
An occasional night when sleep just won’t show up is pretty normal. Stress, a changed schedule, caffeine, travel, or even worrying about not sleeping can keep you awake—annoyingly, trying harder to sleep doesn’t always help.
If you’re regularly getting little or no sleep, or it’s affecting your mood, focus, or daily life, talk with a healthcare professional. You don’t have to wait until you’re completely running on fumes.
