Does your brain switch off when you sleep?
Does your brain switch off when you sleep? The myth is that everything goes quiet. This Short puts that next to what brain scans show: through the night your brain cycles between stages, and some of them are as active as being awake.

What it says
Myth: your brain switches off when you sleep. Fact: sleep looks like rest from the outside, but brain scans tell a different story. Through the night the brain cycles between stages, and some of them are as active as wakefulness. That is why dreams can feel vivid, and why a sound or a worry can still reach you. The National Institute of Neurological Disorders and Stroke summarises this pattern in its Brain Basics guide to sleep.

The sleep calculator uses the same cycle idea to suggest bedtimes. For other myth vs fact Shorts, see does exercising at night ruin your sleep? and does alcohol help you sleep?.

About these Shorts
Our myth vs fact Shorts put one common sleep belief next to what the evidence says, with the source listed below. There is no voice: the myth and the fact appear as text over an AI-made glass dome under the stars.
Busy is not broken
An active sleeping brain is normal, not a sign that you are “bad at sleep.” Memory, mood and body repair all lean on those overnight cycles. The goal at bedtime is usually to make it easy for the next cycle to begin, not to shut the mind down completely.
