Jet lag
Flying through different time zones can cause your natural body clock to get messed up. The effect this has on your body is commonly known as "jet lag" - it can disturb sleep patterns, upset digestion, effect your memory, lessen your ability to concentrate, and generally make you feel washed out and irritable.
However, there are several things you can do to minimise the discomfort caused by jet lag.
Time
Some people find it helpful to adjust their watch to the new time zone as soon as they start their flight, so as to give their bodies maximum opportunity to get used to it - however, this may not be appropriate for people taking regular medication, such as people with diabetes.
On arrival at your destination, adjust your mealtimes and bedtime in line with the new time zone as soon as possible. Being exposed to natural day light is also said to help your body to synchronise with the new time zone.
Sleep
In order to help your body to acclimatise to the different time zones:
- if you are flying east, try to go to bed earlier for a couple of nights before you fly
- if you are flying west, try to go to bed later for a couple of nights before you fly.
Get plenty of sleep before the flight, and try to have a sleep during long flights.
Drinks
Don't let yourself get dehydrated - drink plenty of water before, during and after your flight. Try to avoid drinking alcohol or caffeinated drinks during the flight.
Exercise
Exercise during the flight - stretch in your chair, have a walk about the cabin (when it is safe to do so), and exercise your feet and legs.
