is working at night is bad for us ?

extra work can harm your whole body
In some jobs, working the night shift is unavoidable. There are hospitals to run, planes to fly and shops to keep open as we move towards a 24-hour society. With careful planning and a bit of peace during the daytime, it is possible to work all night and still get eight hours sleep the follow day. Some people will even tell you they don’t mind and that they get used to working in this way. But can their bodies ever become fully accustomed to working to a clock turned upside down? And, more worryingly, is nocturnal labour bad for your health?

There are two elements to these questions. One is about how we feel – our mental wellbeing. People are right to say they get used to shift work. There’s evidence that we cope with subsequent night shifts better than the first of a series, but some people find it much harder than others.
