Circadian rhythms are the body’s way
of scheduling daily activities such as eating, waking, and sleeping.
These events are executed with the help of hormones that are released
from the brain and from other parts of the body.
And, to do these effectively, circadian rhythms are synchronized with nature’s day-and-night cycle. Let’s take the hormone melatonin as an example. This is a sleep-inducing hormone but it is not usually released during the waking hours because light coming from the sun blocks it. When the sun sets and light from the surroundings becomes dimmer, melatonin is released, signaling the body that it is time for bed.

Circadian rhythms help maintain the
health of the body. They assure that the body gets enough food and rest
to be able to function properly. However, these rhythms can be out of
sync too, due to the production of hormones and other chemicals at the
wrong time of the day, or the amount released may be too little to have a
significant effect on the body.
Circadian rhythm disorders can also be caused by changes in time zone and work schedule, certain medications, illnesses, and pregnancy. These disorders can upset a person’s moods and sleep-wake cycle, which, in turn, may greatly affect his or her life.
