All the light therapy you need in one neat device


Combination product that's a wake-up light in the morning and provides bright light therapy when you need it during the day.
  • Zest can be used as a wake-up light for a natural start to the day. Waking up with a gradual sunrise is a signal for your body to ease production of sleep hormones (e.g. melatonin) and increase those that help you get up and go (e.g. cortisol). Wake-up lights help to keep your sleep cycle on track, boosting mood, energy and productivity levels all day.

    In addition, you can use Zest for bright light therapy in the winter months or when you're stuck indoors. Extra bright light is proven to put you in a better mood and make you feel more awake and using Zest every day will make a big difference to symptoms of SAD such as tiredness, over-eating and a lack of energy and motivation.
