Circadian rhythms are biological cycles that regulate various physiological functions over a 24-hour period, influencing sleep, body temperature, and alertness. The document outlines an experiment where an individual tracks their natural waking, eating, and sleeping times over a week without external alarms. Participants will then analyze the recorded data to understand their own circadian patterns.

1. 050 CIRCADIAN RHYTHMS / BIOLOGICAL CLOCKS
CONCEPT
The daily rhythms to many of our physiological functions and activities
such as sleep, body temperature, alertness, neurotransmitter levels that
run on 24 hour cycle are known as "Circadian Rhythms".
Organisms have an inbuilt and nearly automatic rhythm which repeats
itself at about 24 hours interval.
These rhythms are found in almost all the major taxonomic groups
of animal and plant kingdoms.

2. MATERIALS REQUIRED
• Clock
• Pen
• Paper to record

3. This experiment has to be done continuously for a week.
Do not set the alarm in the clock to get up in the morning and also
nobody else should wake you up. Get up on your own and then note
down the time date wise and day wise on the paper every day you wake up.
When feeling hungry during breakfast again note down the time.
Similarly do it for lunch and dinner times and finally the time you feel sleepy.
After one week try to correlate the timings recorded by you.
