Sleep is essential for our health and wellbeing. Just like eating, we need sleep to survive. Sleep gives our bodies a rest and prepares us for the next day. It allows our bodies and minds to recharge, leaving us refreshed and alert when we wake up. Sleep is also when our brains store new information, get rid of toxic waste, and solve problems. Without enough sleep, our brains cannot function properly, impairing our ability to concentrate, think clearly, and process memories.
