It is nearly time for your holiday and, if you are lucky enough to be flying off to another time zone, then you will probably have to deal with jet lag. Jet lag means that your body’s biological rhythms are upset. Your biological clock is found in the brain and it’s what makes you hungry every day around the same time, what controls your body temperature, but also what makes you feel tired and awake again. Your biological clock has a fixed rhythm of about 24 hours.
When you return from a holiday or arrive at your holiday destination, then you might well find that you can hardly stay awake during the day and suddenly feel really hungry in the middle of the night.
It is easy to change your watch when you arrive, but your biological clock is more of a challenge. On average, we need a day to adjust to a one-hour time difference. The extent of the impact depends on the person, but it is possible to do something about it. A fun case from the sports world and tips to beat jet lag!
Elite athletes are often faced with jet lag. Many international competitions and training camps are held all across the world, which means that they prefer to travel weeks ahead of the competitions in order to acclimatise.
Research published in 2013 on American football players demonstrated that teams from the west coast won twice as often as teams from the east coast, and that this was partly due to the impact of jet lag.
Indeed, your peak physical performance occurs between 5 and 7 p.m., and is determined by your biological clock. Most football matches are played between 8 and 10 p.m. and the average time difference between the west and the east coast is about three hours.
Therefore, when players from the west coast have an away match on the east coast, they play the match when their biological clock tells them that it is somewhere between 5 and 7 p.m., and therefore an ideal time for delivering a great physical performance. When players from the east coast play an away match on the west coast, however, they play the game when their biological clock tells them that it is between 11 p.m. and 1 a.m. Bedtime, in other words.
