What is sleep?
While you are sleeping your brain and body functions are still active. Sleep is a natural process that helps your body restore energy, supports learning and memory, and keeps you healthy.
It's not just the number of hours of sleep you get that matters. The quality of your sleep is also important. During the night, your brain cycles through different stages of non-rapid eye movement (non-REM) sleep and rapid eye movement (REM) sleep. If your sleep is often interrupted, you may not get enough time in certain stages of sleep. Poor-quality sleep does more than make you feel tired. It can affect your physical and mental health, thinking, and daily functioning.
