AP PSYCHOLOGY

Detailed explanation-1: -Sleep is important to a number of brain functions, including how nerve cells (neurons) communicate with each other. In fact, your brain and body stay remarkably active while you sleep. Recent findings suggest that sleep plays a housekeeping role that removes toxins in your brain that build up while you are awake.

Detailed explanation-2: -Sleep allows the brain and body to slow down and engage in processes of recovery, promoting better physical and mental performance the next day and over the long-term. What happens when you don’t sleep is that these fundamental processes are short-circuited, affecting thinking, concentration, energy levels, and mood.

Detailed explanation-3: -More specifically, when one sleeps, the brain resets itself, removes toxic waste byproducts which may have accumulated throughout the day [2]. This new scientific evidence is important because it demonstrates that sleeping can clear “cobwebs” in the brain and help maintain its normal functioning.

Detailed explanation-4: -The waste management system (called the glymphatic system) is a series of tubes that carry fresh fluid into the brain, mix the fresh fluid with the waste-filled fluid that surrounds the brain cells, and then flush the mix out of the brain and into the blood. This occurs primarily during deep sleep.

Detailed explanation-5: -Raising the volume of your radio will help you stay awake while driving. False. If you’re having trouble staying awake while driving, the only short-term solution is to pull over at a safe place and take a short nap or have a caffeinated drink.
