How it works

Your body clock and the Re-Timer
Sunlight is the cue our bodies use to regulate our sleeping and waking pattern. When light is received by photoreceptors in our eyes, a signal is sent to our brain telling us to be awake and alert. Often, however, we do not receive the daily bright light we need to maintain a well-timed body clock and natural energy levels.

The Retimer is a portable light device that mimics the benefits of sunlight. Unlike the sun, however, the Retimer is 100% UV-free and able to be used on an overcast day or during long winters when the sun is not visible. This evidenced-based, patented technology has been developed through 25 years of university research by leading sleep psychologists.

Use the Retimer to:

  • Reduce jet lag by retiming your body clock in small steps before you travel
  • Increase energy during the long winter months
  • Overcome sleeplessness by retiming your body clock to your preferred sleep schedule
  • Manage fatigue if you are a shift worker

Frequent flyers: Re-Timer, the travel habit of successful people
 94% of passengers experience jet lag after a long haul flight. Using the Retimer before departure allows you to begin adjusting your body clock before you leave. This can reduce the effects of jet lag and improve your alertness levels.

‘Using a light device allows you to transition your body clock to a new time zone in small steps. This eliminates the sudden change people experience after flying and reduces the symptoms of jet lag’, says Professor Leon Lack from Flinders University.

Before leaving Sydney for Berlin, Ben entered his trip details into the jet lag calculator. He followed the plan the calculator gave him:
Before leaving Sydney:

  • Monday – wear Retimer at 9.30 pm for 50 minutes,
  • Tuesday – wear Retimer at 10.30 pm for 50 minutes,
  • Wednesday – wear Retimer at 11.30 pm for 50 minutes,

Once in Berlin:

  • Thursday – wear Retimer at 9.30 pm for 50 minutes

By making the transition in small steps Ben was able to avoid the nausea he usually experiences.

Sleeplessness: Re-Timer, helping you re-time your life
Approximately 10% of all cases of sleeplessness are due to a mis-timed body clock. This is often the result of not enough bright light during the day. To determine whether your sleeplessness is due to a mis-timed body clock, please consult your sleep physician: see whether Retimer is the best solution for you.

‘Most of our research has been focused in this area. We have found good results with people who suffer delayed sleep phase (go to bed later than they wish) or advanced sleep phase (go to bed earlier than they wish)’, reports Professor Leon Lack.

Heather was falling asleep at 2 am each morning but needed to wake up at 7 am. Just 5 hours of sleep each night was leaving her feeling lethargic and irritable. Heather started to use a bright light device between 6 am and 6.50 am for 5 mornings in a row. On the fifth day, Heather fell asleep at midnight – 2 hours earlier than she normally would. Early morning use naturally advanced her sleep phase to an earlier time.

Shift workers: Re-Timer, promoting safety in the workplace
Shift workers make up 16% of the population. Studies report that 30% of these workers suffer from daytime sleepiness. For companies operating in logistics and heavy industries, worker fatigue can result in workplace accidents and lost productivity.Professor Lack says, ‘Light can help a shift worker re-time their body clock, so they feel awake and alert whilst on the job. Furthermore, we know light has a waking effect on the body, so using light before a shift can assist your alertness levels’.

Example 1:
Cathy is a registered nurse who works the night shift at a hospital from 8pm to 6am. She used to have trouble remaining focussed and alert, and often felt drowsy during her shift. Cathy then found it difficult to fall asleep and stay asleep once she got home.

Now Cathy uses a light device for 50 minutes when she wakes up before her shift. This makes her feel more awake and alert while at work, and allows her to fall asleep when she gets home.

Example 2:
At 6 am Mark arrives at work and the sun is not up. To help him feel more awake and alert he uses a light device for 50 minutes to start his day. The soft glow and portability of the device allows him to respond to emails he received overnight while using the light device.

Winter blues: With Re-Timer, higher energy levels help you get the most out of everyday
A lack of natural light can lead to reduced energy and reduced mood. As many as a quarter of Scandinavians suffer the winter blues between December and February. Even in countries without severe winters, studies have shown that light can improve your mood during the winter months.

Sarah was feeling depressed during the winter months. She began using her light device for 50 minutes each morning on the advice of her general practitioner. Sarah noticed an improvement in mood within 2 days and now uses her light device at least 3 mornings each week during winter to maintain her mood and energy levels.
