Sleep is still a mysterious yet very important part of our lives.
Are you unconscious when you sleep? Can you learn new languages or prepare for exams while asleep? Can you sleep with half of your brain while the other half is awake and alert? Do all of us have have an internal biological clock? Why is sleeping through the night like riding a roller coaster? Does the brain stop working while we sleep? Is resting or relaxing just as good as sleeping? How does 24/7 access to screen time affect sleep? Does everybody dream or just some people? What is sleep paralysis? Do newborn babies have dreams? Can shift work harm sleep and health and cause accidents?
