What Time Of Day; How Long - Lumie Brightspark Guide D'utilisation

English

What time of day?

If you're using Brightspark to help with the winter blues or SAD,
bright light in the morning has been shown to be most effective so
try that first. For some people, early evening light exposure is
beneficial. Whether you're using Brightspark for winter blues, SAD
or as a general pick-me-up, once you've found a pattern that's right
for you, try to use it around the same time every day.
I find it difficult to get going in the morning
Switch on as soon as you can. If you don't have much time in the
morning, then you should aim for a top-up or full session in the
afternoon.
I feel sleepy or fall asleep too early
Use Brightspark in the late afternoon/early evening. It's best to
avoid bright light too close to bedtime - within about three hours -
as you may find it difficult to get to sleep.

How long?

Everybody's different but, if you use Brightspark at about 50cm/20in
as suggested, 40-90 minutes will probably be enough for effective
SAD treatment. There's no harm in using it for longer and you can
even make up this time by dipping in throughout the day.
If you're more comfortable with it further away, then less light will
reach your eyes and you'll need to use it for longer.
If you find your eyes ache slightly, try moving it further away or
switch off for a while.
