CONCEPT
050 CIRCADIAN RHYTHMS / BIOLOGICAL CLOCKS
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.

  • Paper to record

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.
