Jet lag is also known as desynchronosis which is a temporary disorder causing extreme tiredness, insomnia and other sleep disorders due to air travel across different time zones. Some people may also suffer from other ailments resulting out of jet lag, these are:
Some also complain of heartbeat irregularities but this is usually rare.
Why does jet lag happen?
Most often when a traveler is unable to cope with different time zones, waking up and sleeping at different time zones the body reacts differently trying to adjust and this suffering due to the irregularities is known as jet lag. When the body tries to cope with the new schedule, sleeplessness, tiredness, irritability and the inability to concentrate, it is known as jet lag. The changed bathroom may cause constipation or diarrhea while the sleep disorders occur as the brain tries to juggles the schedules to work well.
How does the body keep time and the role of melatonin?
There is a small part in the brain called hypothalamus that acts like an alarm clock to activate the body functions timely like thirst, hunger and sleep. The body regulates the body temperature, regulates the blood pressure and the levels of hormones and glucose in the bloodstream. To help the body to keep time of the day, the fibers present in the optic nerve of the eye transmit light and darkness within the hypothalamus. Hence, when the traveler perceives dusk or dawn at odd hours that is not normal the hypothalamus triggers activities that the body is not ready for and this leads to jet lag.
Melatonin is a hormone that helps to maintain body rhythms and jet lag. At sun sets, the eyes see darkness and urge the hypothalamus to release melatonin which promotes sleep. Similarly when the eyes see sunlight they urge the hypothalamus to withhold melatonin production, but, the hypothalamus does not re-adjust its schedule instantly; it takes time.
