Jet lag
Rapidly traveling across several time zones puts your internal body
clock out of sync with the new external time. This not only causes
sleeping problems, but also influences your mood and energy level. If
you stay for more than a few days in the other time zone, you may
want to shift your body clock to the new time zone. This will help you
sleep better and be more alert and energetic when you need to. One
of the best strategies to deal with jet lag is to start shifting your body
clock and sleep times several days before you leave.
Traveling east
When you travel east, you have to advance your sleep time by a
number of hours that equals the time zones you cross. You can shift
your body clock forwards in steps of one hour a day. The number of
time zones you cross determines how many days before departure
you have to start using the Philips EnergyUp. Use the appliance for 30
minutes after you wake up. Avoid bright light in the evening and go to
bed early. When you arrive at your destination, avoid bright light
during your normal sleep period. Expose yourself to bright light at the
end of this period to advance your body clock further to the local
time.
Before your return flight, use the Philips EnergyUp late in the evening
for a couple of days. On the last night of the trip, try to stay up and
use the appliance as late as possible after midnight. On the day of the
flight, avoid any bright light in the morning.
Traveling west
Since most people's body clocks adjust more easily to later time
zones, you only have to use the Philips EnergyUp for one day before
you travel across four time zones. Add an additional preparation day
for each three additional time zones. You do not have to use the
Philips EnergyUp for more than three days, even on longer
westbound trips. Use the appliance for 30–40 minutes late in the
evening. Start two or three days before you leave. Use the appliance
two hours later the following nights.
