Electronic Components/Answered Question

Subject: Biological Clock / Circadian rhythm
Question: Dear Deirdre


Most of the Offices,Industries are working in Day Shifts all over the world and maybe 5% working in Night Shifts.

Day Work Timings :
10 am to 6 pm, 9.30 am to 5.30 am, 9.00 am to 5 pm.

Night Shift Work Timings :
10 pm to 6 am, 9.30 pm to 5.30 am, 9.00 pm to 5 am.

Observed that job workers working in Night Shifts tend to feel
sleepy and cannot give 100% work efficiency.

What could be the Biological Factors influencing this ?. Is it because of going against the Biological Clock / Circadian rhythm laws ?.

Awaiting your inputs & views,

Thanks & Regards,
Prashant S Akerkar
Answer: Part of it might be biological clocks, but there is another answer. People who work night shifts need to sleep during the day. Cities are much more noisy during the day, which makes it more difficult to sleep. So people working at night don't get as much rest.

Also, many who work at night try to do things during the weekend, during the day. This means that they don't maintain a regular sleep / wake cycle.
