Frequently Asked Questions
How often should I use Zest for winter blues?
Look out for early signs of winter blues in Sept/Oct and if you start feeling more tired, anxious or irritable, start using Zest. As spring comes around, you can cut back on your bright light sessions. If symptoms return, simply use Zest again for a few days.
When should I use Zest for bright light therapy?
Most people find that bright light therapy works best in the mornings so we recommend that you try this first. If you find it difficult to get going in the morning, use Zest as soon as you can. If you don't have time in the mornings, you can aim for a top-up or full session in the afternoon but try to avoid exposure to bright late in the evening as you may find it difficult to get to sleep.
Does the display stay on during the night?
Zest’s clock display has a default setting to automatically dim to a low level during the night; however, you can change this to off or to stay bright during the night.
