Resetting your body clock to tick along with the time of new destination can be tough, and no-one wants to lose any precious holiday time feeling groggy. Jet lag occurs when you travel quickly across more than two times zones leading to confusion between your internal body clock and the local time – and it’s worse when you travel eastwards because we lose time. Prepare your body clock by going to bed and getting up an hour earlier each day for a few days before.
