Sleepy Teens

The stereotype of teenagers is now pretty well established – lazy youths who sleep until midday, mope around for the rest of the day before staying up on their computers into the early hours. However, this shift in attitude and lifestyle is not simply teenagers being rebellious, it is actually a biological change in their bodies that causes their body clock to change to much later.

What causes the change in teenegers' body clocks?

During puberty, a teenager's circadian rhythm (body clock) shifts from a morning preference to an evening preference. Sleep is controlled by the body's hormones, and during puberty the body is changing the types and quantities of hormones that it produces - which has an effect on when it needs sleep. This means teenagers do not start becoming alert and able to focus until noon, making them less sociable in the mornings and affecting the quality of their studies and work.

What are the effects of the disrupted circadian rhythm?

How to solve the problem

Clinical research has proven that exposure to bright light of specific wavelengths can shift a teenager's internal body clock and regulate their sleep patterns. Exposure to bright light for 15-30 minutes upon waking will allow the body to suppress melatonin – the chemical the brain releases to aid sleep – allowing them to feel alert and focussed in the morning and during the day, and then to feel tired at an appropriate time in the evening. This process is called "phase shifting", and light therapy has been proven to be the most effective and natural method.

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.
