Expert Solution

B) Circadian rhythm is an internal and natural process which controls the sleep-wake cycle and resets around every 24 hours.

1. Functions of sleep

Functions of sleep include brain function, memory, and physical health. Sleep plays a very important role in the proper function of the brain, memory, and physical health.

2. Biology of sleep

There are two biological functions - circadian rhythm and homeostasis.

Homeostasis refers to any biological process that is self-regulating and helps the biological system maintain stability. Homeostasis is what drives us to sleep according to the duration of our wakefulness.

3. Realms of sleep

Non REM and REM.

Non-Rapid Eye Movement

There are 3 stages in non-rem sleep

stage 1 - when you have just gone to bed. your eyes are closed but you are easy to wake up.

stage 2 - when you are in light sleep.

stage 3 - when you are deep sleeping.

Rapid Eye Movement

REM occurs approximately after 90 minutes you fell asleep. This is when we have intense dreams.

4. Symptoms of sleep deprivation

Fatigue, yawning (very often), excessive sleepiness, irritability, lack of concentration, forgetfulness, increased appetite and craving for carbohydrates.
