Is it normal to talk to yourself in your head constantly?
Mostly.Normal for most people
Yes, frequent inner self-talk is normal. Some people have a nearly constant inner monologue, while others think more in images, feelings, or fragments.
Your inner voice might narrate what you’re doing, rehearse conversations, make lists, or argue both sides of a decision. Lots of people do this, and there’s no single “normal” amount of inner speech—some people barely notice it, and others have a running commentary most of the day.
It’s usually only worth paying closer attention if it feels distressing, gets in the way of sleep or daily life, or seems like a voice that isn’t your own thoughts. Otherwise, a busy mind is just one way of thinking, not a sign that something is wrong.
