Position Desklamp at arm's length with the light angled towards your face, and start with 30 minutes of exposure per day. 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 Desklamp positioned further away, 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 Desklamp 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 Desklamp for winter blues, or for general wellbeing, once you’ve found a pattern that’s right for you try to use it in light therapy mode around the same time every day.

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 Desklamp in light therapy mode 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.

Look out for early signs of winter blues in Sept/Oct and if you start feeling more tired, anxious or irritable, start using Desklamp in light therapy mode. As spring comes around, you can cut back on your bright light sessions. If symptoms return, simply use Desklamp in light therapy mode again for a few days.
