Our body clock influences the timing of all our bodily rhythms: our sleeping and waking patterns, alertness, performance levels, and metabolism. These rhythms vary regularly (up and down) over a 24-hour cycle, and are influenced by light. To time these rhythms, photoreceptors in our eyes detect bright light.

Often, however, we do not receive the amount of daily bright light we need to maintain a well-timed body clock and natural energy levels. This can be due to working indoors, seeing too little sun during the long winter months, or deliberately avoiding the sun because of concern over UV rays. Indoor lighting is usually not sufficient to time our body clocks. The Re-Timer glasses were created to provide a portable and 100% UV-free light source.

Product features:

  • The light from Re-Timer glassess can be used to adjust your sleep cycle
  • Re-Timer can be used to help change when you sleep and wake. Ideal for travellers who need help combating jet lag, shift workers and overcoming a lack of natural light during long winter months
  • University developed based on 25 years research by world-renowned sleep psychologist Prof. Leon Lack and Dr Helen Wright at Flinders University


What is Light Therapy?

Light therapy (or phototherapy) involves exposure to specific wavelengths of light for a prescribed amount of time at a specific time of day.

Why is light important to our sleep rhythm?

When your eyes sense light, your body responds by being more awake and alert

If you do not receive light at the right times due to the winter months or lifestyle factors, this can confuse your circadian rhythm leaving you unable to sleep when you need to or contribute to a low mood experienced in winter. 


Light Therapy for Sleep

Light therapy is a natural solution to help you maintain a routine sleep cycle. Light therapy can also assist change the times you sleep and wake.

If you are unable to fall back to sleep after waking early in the morning (advanced sleep phase) or have difficulty falling asleep at the beginning of the night (delayed sleep phase) Re-Timer can help adjust sleep back to your preferred time. 

When your eyes detect bright light, your body responds by being more awake and alert. This process also helps your body to understand when it’s time to sleep. Re-Timer light therapy glasses use light to help you maintain a consistent sleep–wake rhythm.

How does Re-Timer help sleep?

Re-Timer naturally helps you adjust back to your preferred sleep time. 

Difficulty falling asleep may be the result of a delayed body clock. Thirty minutes of Re-Timer in the morning will assist you in falling asleep earlier.  

Waking too early may be the result of an early-timed body clock. Thirty minutes of Re-Timer use in the evening, shortly before going to bed will assist you in waking up later, and possibly sleeping longer. 

How does Re-Timer help beat Jet Lag?

Jet lag is caused by a misalignment between your sleep rhythm (internal body clock) and your destination time. When you travel across time zones, your body doesn’t know whether to be awake or asleep. This causes you to feel jet lagged.

Re-Timer can help. 

If you’re travelling east you will find it harder to fall asleep at night. Wearing Re-Timer in the morning will help you to fall asleep earlier.

If you’re travelling west you will often feel tired too early. You will experience interrupted sleep, waking throughout the night and trouble remaining asleep. Wearing Re-Timer in the evening will help you adjust back to your normal sleep patterns.

Re-Timer is the travel habit of elite athletes, executives and holiday travellers around the world. 

How does Re-Timer help with Shift Work?

Shift work can leave you feeling permanently jet lagged.

If you are a shift worker Re-Timer can help you with your night shift. Re-Timer can help you feel awake at work and adjust back to your normal sleep pattern when you get home.

Wearing Re-Timer for 30 minutes per day will:

  • start adjusting your sleep time before your first night shift
  • help you stay awake at work
  • enable you to wake up earlier on your days off, and
  • help shift the time you feel most tired out of your shift (i.e. from the early hours of the morning to the time you get home and want to go to sleep)..

How does Re-Timer help to beat long winters?

Long Winters is a low mood related to shorter days and reduced sunlight exposure in the winter months. Lack of light can lead to loss of energy, weight gain and difficulty concentrating.

Re-Timer can help.

When your eyes receive light, it sends a signal to your body which helps you feel awake and alert. Using light therapy can have a positive effect on your mood and can leave you feeling more energized.
