Here’s your hot take for the day: sleep is critical to brain function. Yes, we know you’ve heard that many times. However, you’ve heard that so much because it’s true. Even though we may be sleeping, our brain isn’t turned off. It’s still functioning and doing its job to keep us healthy. For one, our brain never stops firing neurons.
When awake, our brain is always working to perform the random acts of the day. During sleep, the brain has a chance to catch up and recycle toxins through a drainage system called the glymphatic system. Sleep also improves our learning capability and capacity by allowing our brain to create and consolidate memories.
