What is jet lag? Jet lag results from disruption of circadian rhythms in the human body. Circadian rhythms pertain to changes in body function that occur throughout a 24-hour period. These circadian rhythms regulate mental alertness and the propensity to fall asleep. In simple words, Jet lag is a temporary condition that some people experience following air travel across several time zones in a short period of time their body clock that regulates sleep, wakefulness, and other activities is disturbed.

Jet lag can also cause daytime fatigue, stomachaches, headaches, irritability, and decreased awareness. A study conducted at University of Bristol has found that too much jet lag can affect the memory and impair thinking. The study was carried on female cabin staff that had been flying across time zones for more than four years and identified that these women had slower reaction times and worse short-term memory compared to their other staff colleagues. However, it was not identified whether the deficiencies were temporary or permanent. Severe cases may lead to more serious sleep disorders, such as delayed sleep-phase syndrome - the habit of falling asleep at very late times and advanced sleep-phase syndrome - the ha
