This is a new memory-learning memory. It is a good thing for you to get enough sleep, and a bad thing for you if not. People need to sleep before learning, and people also need to sleep after learning. When you are asleep, the memory can consolidate all the information into your brain. From this point, it may only get worse. Not only will I tell you about the wonderfully good things that happen when you get sleep, but the alarmingly bad things that happen when you don’t get enough both for your brain and your body. Let me start with the brain and the functions of learning and memory, because what we’ve discovered over the past 10 or so years is that you need sleep after learning to essentially hit the save button on those new memories so that you don’t forget. But recently, we discovered that you also need sleep before learning and now to actually prepare your brain almost like a dry sponge, ready to initially soak up new information. And without sleep, the memory circuits of the brain essentially become waterlogged, as it were. And you can’t absorb new memories.

Adequate sleep is crucial for effective memory and learning. It helps consolidate new information after learning and prepares the brain to absorb new knowledge beforehand, akin to a dry sponge. Lack of sleep impairs memory circuits, hindering the ability to retain new information. Understanding these effects highlights the importance of sleep for both brain and body.
