Jet lag is also known as time zone change syndrome or desynchronizes. Jet lag can occur when people travel rapidly from east to west or west to east on a jet plane. It is a physiological condition which upsets our body's circadian rhythms - hence, it is classified as a circadian rhythm disorder. Jet lag symptoms tend to be more severe when the person travels from westward compared to eastward.
People with jet lag have their sleep-wake patterns disturbed. They may feel drowsy, tired, irritable, lethargic and slightly disoriented. The more time zones that are crossed rapidly, the more severe jet lag symptoms are likely to be.
New research shows the disruption occurs in two separate but linked groups of neurons in a structure called the Suprachiasmatic nucleus, below the hypothalamus at the base of the brain. One group is synchronized with deep sleep that results from physical fatigue and the other controls the dream state of rapid eye movement, or REM, sleep.
The older a human is, the more severe are their jet lag symptoms, and the longer they will take to get their body clocks back into synch. If a 60 year-old adult travels with a child from San Francisco to London by plane, the child's symptoms will usually be much milder, and he/she will recover faster.
A simple, at home treatment – light therapy allows travelers to avoid jet lag by resetting their circadian body clock before crossing several time zones.
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 overcome the symptoms of Jetlag.
