How Jet Lag Works

Jet lag, occurs after air travel when your body clock isn’t synchronized with your new time zone. It can disrupt more than 50 physiological and psychological rhythms. Unfortunately it also gets worse with age – particularly after age 50. New research suggests that it also causes memory loss, shrinkage of parts of the brain, and negative side effects on blood pressure. Unaided, it takes your body 1 day per time zone to readjust. It may take 2 to 3 weeks to completely realign your rhythms.

How Litebook Cures Jet Lag

Clinical research conducted at NASA and elsewhere demonstrates that with a properly timed exposure to bright light in specific wavelengths, and a similarly timed avoidance of light, it is possible to safely and efficiently shift our body clock up to 6 time zones in 1 day, and up to 12 time zones in 2 days. With proper use of The Litebook®, your energy, mood, concentration, performance and sleep patterns can all be reset to your new time zone in as little as 60 minutes.
