What Is Circadian Rhythm?

It is a Physical, Mental and Behavioral change observed by all the living beings including Animals, Plants, and Oxygen Producing Bacteria in a 24-hour cycle process.

In Simple Words, the rhythm that keeps track of Sleep and Feeding schedules or patterns based on Light and Temperature in living beings.

Biological Clock Vs Master Clock:

– Circadian rhythms are controlled by our Biological Clock.

– The Biological Clocks in our body are managed by the Master or the Primary Clock which resides in our brain.

– A Circadian Rhythm is linked to Brain Wave Patterns, Hormones and brain chemical secretions, Cell regeneration and even more.

The Involvement Of Sunrise And Sunset:


  • The Neurotransmitter that gets triggered by Sunlight.
  • When the sun rises, the production of Melatonin in our body stops and the production of Serotonin starts.
  • It regulates our Mood, Thinking Abilities, Hungriness and also Motivates us during the day.


  • The Hormone which makes us sleep during the night.
  • When the sun starts to set, the Serotonin production stops in our body leading to the production of Melatonin.
  • Melatonin regulates the Circadian Rhythm.

  • Avoid staying all night in front of the TV or similar.

Things To Remember:

  • Studies have shown that a power nap or a quick nap in the noon increase productivity and reduce stress. But, no study has proved that the power nap can compensate the lost sleep during the previous day’s night.

A quick nap during the day at work or during weekends will not help in resetting your circadian rhythm.

It is always good to have a real quick sleep at work after lunch. When I say it’s good, I am referring to the 15-30 minutes nap. A Good Sleep plays an important role in finalizing a person’s success in career and in life.

Besides, it is very normal for people to sleep off when they are dog tired but not all the times.

Remember that too much of anything is good for nothing. If you think that your sleep pattern falls into the abnormal category then it is time for you to dig on to it to find the root cause and take necessary actions.

Lack of sleep during the night can be because of Insomnia, Sleep Apnea, Parasomnias etc.
