Days and nights are there due to some reason. Days are to work and nights are to rest. It is a history of human being that whenever we deviate from natural path, we have to face the consequences. Nightwork is getting common these days. In order to maintain higher status, we sacrifice our comfort. To get more dollars, we sacrifice our sleep and get engaged in a night shift work. Some people think that light night shift jobs are not bad for their health which is a misconception. It is not the nightwork which is bad for us, actually it is the lack of sleep and rest in the proper timeframe. Night is made for rest, a 5 hours sleep and rest in the night cannot be compensated with a whole day sleep.
A friend of mine was engaged in a nightwork for almost a decade and I used to tell me to follow the nature and to stay with the day work but he didn’t noticed what I said. Later he developed a strange fatigue which was without a medical reason. All his tests were good then finally he tried to sleep at night for a few weeks and his fatigue went away within first month.
Similarly, I myself have to work during night some times and when I do so, my whole week is destroyed. I think I cannot compensate my one night sleep with the whole weeks sleep afterwards. If you are also engaged in nightwork and feel some strange fatigue or strange change in your body which you cannot name then maybe you shout try to quit nightshift work for a few days and see what happens.
Remember, Nature has made things suitable for us; it is us, who make them unsuitable for us by mismanaging them. In the night, weather is cool and environment is free of noise and light. We can enjoy a deep sleep during night which cannot be compensated with a disturbed sleep of day due to many noises, environmental heat, light etc. If some how you cannot avoid night work, you should still try to sleep from 1am to 4am which is very critical for your health. An experiment is worth a thousand words, so try it and you will know what I say. Please also mention your experience with the night work in the comments area bellow.
