What is non-vision time?

Dr. Mehmet Oz, MD
Cardiology (Cardiovascular Disease)
As we started to take on more cognitive abilities in our evolutionary history, we needed the restorative process of sleep even more. That's because vision is extremely expensive cognitively, meaning that when you're seeing things and processing the world visually, your brain can do little else except that. You need non-vision time (sleep, or to a lesser extent, meditation-type activities) to process information and store it in your memory.

In a way, sleep allows your brain to lay down the code that your mind will use in the future so that you can reset and reboot your system each and every night. It gives your brain the chance to work and consolidate your memories so you can use them in the future. Your body needs that downtime to repair and refresh its systems.
