Jet Lag

Product

Jet Lag

Your sleep-wake cycle is timed by an invisible clock called your circadian rhythm. This rhythm is naturally timed by bright light being absorbed by photoreceptors in your eyes. International travel can interfere with your circadian rhythm resulting in tiredness and fatigue.

Re-Timer provides a UV-free green light source shown in university trials to be the optimal wavelength to re-time the circadian rhythm, allowing you to reduce jet lag.

More about circadian rhythms here.

The science

The circadian rhythm is the body’s natural sleep and wake rhythm that helps you sleep in the evening and wake in the morning. One of the most important external indicators to help keep your body synchronised with this routine is light.

Crossing multiple time-zones upsets your circadian rhythm as the body is required to adjust to a new daylight schedule more quickly than it can adapt. Unfortunately, crossing multiple time zones will confuse the circadian rhythm to the point where it does not know whether it should be delaying (moving backwards) or advancing (moving forwards). This confusion results in days of tiredness and fatigue.

While our bodies are capable of this adjustment, it takes between 3 and 7 days. During this adjustment period, our bodies experience jet lag symptoms.

Re-Timer provides a specialised light that can reduce the symptoms of jet lag. You can begin to adjust your body to your destinations time zone before departing.

Re-Timer essentially removes the sudden change in time zones. This contributes to reducing the severity of jet lag symptoms when you arrive at your destination, helping you to get the most out of your trip.

How to use Re-Timer

Re-Timer is worn like a pair of glasses. The green light source is housed in the bottom portion of the frame and emits a soft green light onto your eyes.

Wear Re-Timer for 30 minutes each day for 4 days prior to your trip. For a precise use program, please use our complimentary jet lag calculator below.

I used the Re-Timer to assist with retiming my body clock for a business trip to South Africa from Australia. I have very young children and try to spend as little time as possible overseas so that I don’t miss out on their childhood milestones. This means I only land a day prior to my work activities. As I was going to be facilitating a workshop I wanted to see if the Re-Timer could assist in speeding up my body clock adjustment so that I could perform at my best.

I wore the Re-Timer on the plane flight to Johannesburg and achieved a body clock shift of 3 hours, so on my first night in Johannesburg I woke up at 2.30 am instead of 11.30 pm. The second night I achieved a shift of 2 hours and woke up at 4.30 am for my first day of work activities. This was perfect as I had ample preparation and rehearsal time prior to the workshop and was awake and able to perform to a high standard until 8 pm on the first night.
I highly recommend that people required to perform straight after international travel should use the Re-Timer.


Love it!

Recently I travelled to Austin, Texas for SXSW 2014 and used my Re-Timers for the first time. This was my third trip to the US and every other time I have suffered from jet lag for at least 4-5 days into the trip after arriving. Previously, every day was a battle to keep my eyes open during normal business hours, before getting a “second wind” in the evening and then struggling to get to sleep.

Using Re-Time’s jet lag calculator on their website, I started using my Re-Timers a few days before leaving Adelaide, then on the plane and for a few days upon arriving. The difference Re-Timer made in shifting my body clock was nothing short of astonishing. I thought they’d probably help a bit but was amazed at how well they worked. I woke up the first morning in Austin with meetings scheduled, feeling refreshed, awake and clear. This continued throughout the day and then that night I went to bed at 11pm and got a solid 8 hours sleep. For regular business travellers, Re-Timers are a no-brainer and will be the first thing I pack on my next overseas trip

So these (Re-Timers) adjust the body clock for jet lag. Work well, and provide a lot of jokes!
