How long? ENG 11
How long?
With the light at full brightness, you're getting the
maximum benefit so position Task at arm's length
(approx. 50 cm) and start with 30 minutes a day
(1 500 lux). You may find this is enough but if you don't
notice much of an effect, increase your exposure each
day until you find something that works for you.
If you're more comfortable with Task positioned further
away, then less light will reach your eyes and you'll
need to use it for longer.
Similarly, if you're using Task at reduced brightness,
then less light will reach your eyes and you'll need to
use it for longer.
There's no harm in using the light for longer than
suggested. You can get your bright light therapy all in
one go or use Task on-and-off throughout the day for
a cumulative effect.
If you find your eyes ache slightly, try using it further
away, reduce the brightness or switch off for a while.
Whether you're using Task for winter blues, or for
general wellbeing, once you've found a pattern that's
right for you try to use it around the same time every
day.
