Sleep pattern and circadian rhythm

  1. 1. CIRCADIAN RHYTHM AND MY SLEEP PATTERNBY FARAZ TAK
  2. 2. MY STORY • As a medical student working in hospitals from 24 hours shift disrupt my sleep pattern and circadian rhythm. • working hours are from 7 am to next day 7 am. • and when i come home i am very tired and sleep for very long hours. • when i wake up i still feel tired. On next day working hours are during day time 8am to 5pm, which again disrupt my sleep pattern.
  3. 3. MY STORY AND NEUROSCIENCE • Most of us sleep during night and awake during the daytime. • Normally during night time melatonin is released which makes us drowsy. • In my case the melatonin release is not much when i am on 24 hours shift. • This disrupt the sleep pattern.
  4. 4. ROLE OF MELATONIN ON SLEEP • Melatonin is a hormone which is released when lights goes off and naturally this happens during night time. • This make us drowsy and fall asleep. • Nowadays the life style change and innovation of artificial light can disrupt the melatonin secretion. • Sitting and working on laptops or watching television or artificial light sources can effect the sleeping pattern due to disruption to melatonin release. During night time when artificial lights are on, brain cannot distinguish daylight and artificial light so the production of melatonin is not sufficient.
  5. 5. TRICK YOUR BRAIN • When I sleep during daytime I limit the light coming into my room and creating a dark environment just like nighttime. • This will trick your brain and gives you a sound sleep. • By this now i am able to sleep well and wake up refresh.
