About Light Therapy

The natural way to beat the winter blues or simply feel alert, energised and more positive


Information from


If you find yourself feeling the 'winter blues' or struggling with jet lag, troubled sleep patterns or seasonal affective disorder, light therapy could help provide safe, natural relief.

A large part of our basic behaviour and biology follows a 24-hour cycle. The sleep/wake cycle is the most obvious one but others such as body temperature, hormone production, cognitive performance and mood are all known to rise and fall during the day. These circadian (daily) rhythms are regulated by the body's internal clock and exposure to sunlight keeps it synchronised to a 24-hour day.


Melatonin is a hormone produced by the body that is important for maintaining a regular sleep cycle. When it's sunny or there's a lot of artificial light, melatonin production is low. As light starts to fade, production goes up. Melatonin levels are a way of telling our body what time of day it is so that it can react accordingly.


Serotonin is another important chemical linked to sunlight. People with depression and anxiety often have only low levels of this hormone, and increasing exposure to sunlight – or using light therapy – is a natural way of raising serotonin levels.

How light therapy helps

Light therapy is a safe, natural and simple way to improve health and wellbeing and, by helping to keep your body clock on track, light therapy also helps to provide an effective solution to sleep problems and other circadian rhythm issues. Light therapy can be used to help:

  • Boost mood, concentration and energy
  • Promote good sleep patterns
  • Waking up feeling brighter
  • Beat jet lag
  • Banish the winter blues
  • Treat seasonal affective disorder (SAD)

Lumie products

Dawn simulators

These wake you up with gradually brightening light to help you get off to a bright start. At the end of the day, a slowly fading sunset helps you relax and unwind, ready for sleep. There are four Bodyclock dawn simulators to choose from, each with different features.

Lightboxes and desk lights

These include bright lights for use at home, like Pharos Compact and Pharos Max, as well as Brightspark and Desklamp that are designed for use at work. Light therapy doesn't take up extra time; simply have your light on while watching TV, having a meal or working at your desk.

LED devices

LED SADlight and Zip use LEDs so they're much smaller and more portable, making them ideal for travelling or taking to and from work.
