8 English Using Zest as a SAD and energy light
Using Zest as a SAD and energy light
When to start light therapy
Start light therapy as soon as you feel the early signs of winter blues or SAD
- often in September or October - if you start to feel lethargic, anxious or
irritable. You should notice positive benefits after using Zest for three or four
days in a row.
Use light therapy every day, but if the weather is bright you may feel you can
skip a day. As spring comes around you will probably start to cut back your
light therapy; your body will tell you if it's too soon and if you notice your
symptoms returning simply use your Zest again for a few days.
Light therapy is proven to put you in a better mood, to boost alertness and to
help you feel more awake so Zest is ideal for use at work. Use it wherever and
whenever you need to restore concentration and give yourself a mental boost.
What time of day?
If you're using Zest to help with the winter blues or SAD, bright light in the
morning has been shown to be most effective.
If you feel lethargic in the afternoon, or fall asleep too early, use Zest 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.
Once you've found a pattern that's right for you, try to use it around the same
time every day.
What settings?
If you use Zest at about 50cm/0in, as suggested, then a 0-minute light
therapy session at 100% brightness is the recommended standard for
effective SAD treatment. If you're more comfortable with the light at less than
maximum brightness then the length of your session is automatically adjusted
to ensure you benefit from your light therapy.
