Why is it that flying to New York from London will leave you feeling less tired than flying to London from New York? The answer may be a clear case of biology not being able to keep up with technology.
This body clocks programmes us to be sleepy twice a day, between 3-5am and again between 3-5pm. Afternoon tea and nap are all cultural responses to our natural biological sleepiness in the afternoon.
That is why traveling in a westward direction is more body-clock friendly than flying east. NASA studies of long haul pilots showed that westward travel was associated with significantly better sleep quan-tity and quality than eastward flights.
One of the more common complaints of travelers is that their sleep becomes disrupted. There aremany reasons for this: changing time zones and schedules, changing light and activity levels, trying tosleep when your body clock is programmed to be awake, disruption of the internal biological clock andworking longer hours.
