Get Some Shut-Eye
Sleep deprivation has been found to do many things to the body. One study even stated that a lack of sleep will cause your brain to eat itself. Though that is the nightmare scenario, it certainly proves how valuable quality sleep is for quality of life. Sleep also plays a highly important role in consolidating memories, the process where memories stored for a short-term become fortified and transform into long-term memory.
That is why you always do things better the next day, whether it deals with hand-eye coordination exercises or speaking vocabulary in a second language. So, if you want to remember everything you are learning, don’t forego sleep for extra hours of study time. Just go to bed.
