Brief Answer:
Peaceful day time is must for night shift workers.

Detailed Answer:
Thanks for your question on Health Care Magic.
I can understand your concern.. Actually our body molds itself in such a way that we are awake in morning and sleepy at night.
This is body's circadian rhythm.
Body functions well if this rhythm is not disturbed.
So if you are doing night shift then initially you might face many problems.
But once your body is adapting this variation, you won't get much symptoms.
In night shift workers, day time sound sleep is very important. There are many distractions in the day time.
So better to take sound sleep in day time.
Better to take heavy breakfast in the morning, light lunch in afternoon and medium dinner at midnight.
You can eat some light snacks in your nighty shift.
Overall night shift is not good for long term health.
Hope I have solved your query.
I will be happy to help you further.
Wish you good health. Thanks.
