In this lesson, you’ll learn what can happen when you stay up past your bedtime. You’ll hear about one of the most extreme sleep deprivation experiments ever recorded, learn how the brain can “power down” in strange ways when it is exhausted, and see why the Guinness Book of World Records no longer tracks this challenge. You will also try a memory activity to compare how well your brain works after a full day awake compared to after a full night of sleep.
Along the way, you’ll uncover why scientists repeat experiments, how distraction can change results, and what your body is busy doing while you sleep. We will also look at how animals like frigate birds and dolphins rest while on the move. By the end, you will understand that sleep is one of the most important ways your body stays focused, healthy, and ready for whatever comes next.
What you’ll learn:
- What your body and brain do when you sleep
- What happens to your body and brain when you don’t get enough rest
