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.
Travelling 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.
When you arrive at your destination, try to stay awake until bedtime
and avoid bright evening light (wear sunglasses) for the first few days.
Before you travel home, avoid any bright afternoon and evening light.
Use the Philips EnergyUp in the morning for a few days.

Light intensity

Use the Philips EnergyUp in addition to the normal room lighting.
The Philips EnergyUp is more comfortable to use in a well-lit room.
Adjust the brightness to a comfortable level. Allow a few minutes for your
eyes to get used to the bright light. If the highest setting is too bright for
you, start using the appliance at a lower setting. Increase the light intensity
if you feel no effect after a week.

How to use the appliance

1 Place the appliance at arm's length (at approximately 50-75cm from
your eyes) within your field of vision. The light must bathe your face
(Fig. 5).
