Philips Wake-Up Light Proven To Help Sleepy Heads Feel Awake On Dark Mornings

November 24,2010

The world’s largest field experiment into light therapy has helped prove that using the Philips Wake-up Light can help the morning ‘get up’ easier despite the dark, winter mornings.

Seven in ten (68%) of those taking part in the study found it easier to get out of bed and it’s not only adults that have benefited; almost three quarters (74%) stated that it is helping to get their children up in the morning too. Moreover, parents will also be pleased to hear that 80 per cent of teenagers and young adults found it easier to wake-up in the morning and feel more alert – ready for the day ahead.

The Philips Wake-up Lights are being tried and tested by residents of Longyearbyen, the most northern town in the Arctic Circle which spends four winter months in total darkness, 63 per cent recognised a positive impact on their mood and disposition after only two week’s use. Imagine what it could do for us Brits as winter solstice – the shortest day and longest night – approaches.

Local volunteers started using the Philips Wake-up Light last month. Before the study started, almost three quarters (72%) said they find it difficult to get out of bed during the winter months.

Dan Adams, light therapy expert and Senior Application Scientist at Philips, said: “Initial results from the volunteers show that their mood, energy levels and ease of waking up have significantly improved by using the Philips Wake-up Light. Light regulates our internal body clock, which produces active hormones during the day and sleep hormones during the night.

“When we wake up without a sunrise, our body does not produce enough active hormones before we get up, which makes us feel groggy and lethargic. By imitating the light emitted by a sunrise, the Philips Wake-up Light has been clinically proven to help wake people up more naturally.”

The initial study revealed that 67 per cent of women feel that the Philips Wake-up Light is having a positive effect on their mood or disposition, compared to 55% of men.

 “With further research to be conducted in Longyearbyen in the coming month, it will be interesting to see if that statistic applies for all ages.  Further research should also offer more conclusive evidence between waking up naturally to light and the improvements in the quality of people’s sleep,”

It’s not just adults who have experienced positive effects after initial use of the Philips Wake-up Light. The research shows that teenagers in Longyearbyen benefited first and foremost by improved mood, followed by ease of waking up.
