Everybody has days when they’ve not had enough sleep and are beat, unfocused, and pointless at work. Most of the people bounce back following a good night’s rest, but on-the-job fatigue can be a continuing problem for folk working the night shift or other irregular hours. This is as their work plan conflicts with their internal ‘body clock’, which dictates that they feel knackered at night ( when they are making an attempt to work ) and animated throughout the day ( when they are attempting to sleep ). This will mean that they get few hours of sleeping, making them more exhausted at night when working. Doctors have a name for this difficulty : shift work disorder ( SWD ). Such protracted sleepiness can end up in work-related accidents and wounds, which can often be especially major in jobs where precision and safety are paramount , for example health care and transport.

The easiest way to alleviate shift work disorder is to restart a standard schedule but for many of us this is not practicable. So analysts have looked at alternative ways to help folks handle their irregular hours.

One approach favoured by many employees is to consume caffeine rich drinks and foods , for example coffee, energy drinks, and chocolate. Analysts have now gathered the best studies on how caffeine is affecting folk whose body clock has been disrupted by either shift work or jet-lag ( which produces similar effects ). They looked at thirteen studies in total. In these studies, a few individuals were given drinks, nibbles, or capsules with caffeine, while others were given matching items without caffeine.
