Everyone who has travelled across a few time zones have experienced jet lag – the extreme tiredness and sleepiness at odd hours. Jet lag occurs when the body’s internal clock is out of sync with the current time zone. With the advent of jet airplanes, travel across different continents have become fast, easy and convenient, but our own body strains to cope with the effect of crossing several time zones so rapidly and our regular pattern of sleep and wakefulness is disrupted. This is because our body’s internal clock is disrupted – the internal biological clock takes cues from the external environment to tell the body when to sleep and when to wake up.
Of all the external cues that synchronises your internal biological clock, the most powerful is light. That is why the internal circadian alerting system is at the strongest during daytime. The internal circadian alerting system is one of the main processes that regulates sleep patterns – it promotes wakefulness and thereby inhibits sleep. Due to jet lag, you may feel sleepy at odd hours, unable to concentrate or remember and decreased strength and efficiency. Researchers have found that people who suffer frequently from jet lag are more prone to diseases than people with normal sleep-wake cycles.
Jet lag is a serious problem with people who travel frequently and it may have a serious impact on their health later. But most of the frequent travellers have to travel for various reasons. For them, light therapy will help to counter the effects to jet lag quickly and effectively. Light therapy by Luminette has been proven to improve sleep and cognitive performances. Luminette also helps to reduce the state of tiredness and increases the energy levels, thereby negating the effects of jet lag.
So if you travel through different time zones frequently, Luminette can help you counter the effects of jet lag and help you regain control of your sleep cycle.
