Why Sleep and Study Breaks are so Important

Like every organ in our body, the brain has to find a way to rid itself of waste. Every cell in the body produces waste, and there are thousands of cells in our brain. The brain, however cannot rid itself of waste like other organs, because of the brain’s lack of lymphatic vessels. Instead of ridding waste through the lymphatic system that other organs use, the brain washes its waste with a fluid called cerebrospinal fluid. The catch is that this fluid only rushes through the brain when we are sleeping—and this is what allows us to have a “clear head” in the morning, and makes our thoughts murky at night. People who claim to do their best work at night may be right, but it is not to say that they do their best work at night and on only 3three hours of sleep. Poor sleep duration and quality has been hinted by some studies to actually increases the risk of Alzheimer’s. If you’re a student, this might be some necessary encouragement to get your proper sleep!
A Huffington Post article also helpfully outlines the need for our brain to take a break—shattering the myth of the “productive” eight hour study session. A study found that replaying memories during a resting period can make earlier memories stronger and act as connectors when making new memories. This study goes along with others which have concluded that when the mind is resting (either daydreaming or sleeping), parts of the brain that aid in memory storage are highly active.
