Actually going to sleep helps you remember what you studied. Sleep is when our brains process information and submit it to long term memory. The longer you wait to go to sleep after learning new material, the more likely you won’t remember it. There’s a lot more sciencey terms and stuff if you look it up. Anyway, this is why we should reintroduce nap time in public schools, why you should study at night before you go to bed, and why the mc should have slept in his future wife’s bed.
