A research has shown that a shot of caffeine is the best way to get rid of sleep during working hours.

Express. co. uk has reported that people who work unsocial hours or through the night may suffer a form of "jet lag" due to disruption of their body clock.

They can become very sleepy and prone to mishaps. For some, such as lorry drivers or doctors, this can have serious consequences.

It has been reported that a study reviewed data from 13 trials where caffeine was given in coffee, "pep" pills or energy drinks to shift workers.

The report further notified that participants taking coffee performed much better and at the same time their memory, attention, perception and reasoning also improved. (With Inputs from Agencies)
