Recent findings suggest that sleep plays a housekeeping role that removes toxins in your brain that build up while you are awake. Everyone needs sleep, but its biological purpose remains a mystery. Sleep affects almost every type of tissue and system in the body — from the brain, heart, and lungs to metabolism, immune function, mood, and disease resistance.

There are five stages of sleep that rotate between non-rapid eye movement NREM and rapid eye movement REM and include drowsiness, light sleep, moderate to deep sleep, deepest sleep, and dreaming. Sleep stages 1, 2 and REM consist of light sleep, while 3 and 4 comprise deep sleep. During stage 1, you drift from being awake to being asleep.

Oddly, despite their numerical order, sleep does not actually progress linearly through the stages. The first 4 stages of sleep are categorized based on characteristics of the body and brain during sleep. Brainwave frequencies differentiate each stage, along with other biologic rhythms. Stage 1 is the lightest stage of sleep — falling asleep, but not quite there yet.

“If deep sleep is about body, REM is about the brain,” says Grandner. “The brain is very active during REM sleep, yet the body is very inactive.

Being awake is a state of consciousness accompanied by heightened perception, realistic thinking, environmental responsiveness and physical activity. In contrast, sleep is a behavioral state of decreased perception, relatively low responsiveness to the environment and physical inactivity or rest.

Now more than ever, we can quantify exactly how good or bad our sleep patterns are. Each morning you can review your heart rate, breath rate and sleep graphs with information about how much light, deep and REM sleep you had the night before. But all that data only makes sense if you know what you're aiming for and what it all means. Here's how to decode your sleep cycles so you can make the most of your shut-eye. Humans sleep in cycles.
