Jet Lag

Prevent and eliminate jet lag with the Litebook EDGE

Cure jet lag in hours - not days

Don't let jet lag ruin your tripJet lag can be a major problem when travelling abroad – whether you're going on holiday or for work. It takes your body one day per time zone to adjust. Putting that in perspective, if you're going on holiday to California for a week, you'll still be suffering from jet lag by the time you leave. Research from NASA has shown that with light therapy you can shift six time zones in just one day. Why spend hundreds, if not thousands of pounds on a holiday without giving yourself the chance to enjoy it properly?

Using the Litebook EDGE, you can speed up your body's readjustment to a new zone in a matter of hours - without the use of any form of drugs. The Litebook is a compact light that fits into your hand and has a built-in rechargeable battery, and comes supplied with four international power adapters.

Jet lag, or dysrhythmia, occurs after east-west air travel when your body clock isn't synchronized with your new time zone. It can disrupt more than 50 physiological and psychological rhythms. Unfortunately it also gets worse with age – particularly after age 50. Unaided, it takes your body 1 day per time zone to readjust. It may take 2 to 3 weeks to completely realign your rhythms. Until recently, jet lag was dismissed as merely an unpleasant side effect of air travel. New research suggests that it may also cause memory loss, shrinkage of parts of the brain and negative side effects on blood pressure. The good news is: it can now virtually eliminated.


“I am a 40 year old fit and healthy female executive who has a demanding work schedule and travels a lot. I am able to switch to a new time zone immediately when I travel to different countries, by using Litebook at the right time. I am now a firm believer in light therapy and a devoted supporter of Litebook”


Clinical research conducted at NASA and elsewhere demonstrates that with a properly timed exposure to bright light in specific wavelengths, and a similarly timed avoidance of light, it is possible to safely and efficiently shift our body clock up to 6 time zones in 1 day, and up to 12 time zones in 2 days. With proper use of The Litebook® your energy, mood, concentration, performance and sleep patterns can all be reset to your new time zone in as little as 60 minutes.

What is special about the Litebook EDGE?

Traditionally, light therapy meant being sat in front of a large lightbox (about the size of a regular mirror) and looking directly into it for an hour. While effective, it was awkward, boring and time consuming. Thankfully, the Litebook EDGE is revolutionising light therapy and making it quick and incredibly easy.

The Litebook EDGE uses white light-emitting diodes (LEDs) to produce its light. Regular lamps have used fluorescent bulbs, which are bulky, expensive to run, and emit harmful UV rays. The white LEDs in the Litebook mean it is much smaller than conventional lamps (just 1% of the size), and because the peak wavelengths of its light replicate those of sunlight exactly, usage time is as little as 15 minutes.

Fits into your hand, and your life

The Litebook EDGE's size and built-in rechargebale battery means it can be used anywhere; on a train, aeroplane, or simply on a desk or table at home or work. Unlike regular lamps, you do not have to look directly into it, you simply have it facing you at an angle. This leaves you free to get on with other things such as eating breakfast, applying make-up or reading a newspaper. It has never been so easy to get the light you need into your routine.

As with any electrical appliance, the running costs of a light therapy unit are an important factor. The fluorescent bulbs in traditional light boxes need to be replaced every 500 hours. As they need to be used for an hour, that means new bulbs every 18 months - and some use as many as 6, at £15 each. As you can see, it does not take long for the running costs to run into the hundreds. With the Litebook, the LED's last for 100,000 hours - that's 11 years of continuous use - or a few hundreds years of proper use. So the only running costs are electricity - costing roughly £5 per decade. Over the course of its lifetime, the Litebook EDGE will save you hundreds of pounds compared to a regular light therapy unit.
