Definition
Jet lag - also known as "time zone syndrome" - is a circadian rhythm disorder associated with moving (usually by plane) from one area of the planet to "another, with different time zones.
Causes
Jet lag is a phenomenon that occurs when - moving from one time zone to another - one's biological clock is altered and in contrast with the light / dark cycles to which it is normally used. Therefore, it can be said that there is a lack of synchronization between one's own circadian rhythms and the new conditions of light / dark alternation of the place of arrival.
Symptoms
The main symptoms that can be induced by jet lag are: diurnal asthenia, sleep disturbances (caused by an "impaired melatonin secretion), loss of appetite, nausea, headache, muscle soreness, difficulty concentrating, irritability, difficulty in digestion, constipation or diarrhea.

During the journey, however - especially if it is very long - it is advisable to try to rest as much as possible, eat light meals, drink plenty of water and avoid the consumption of alcohol or beverages such as tea or coffee.
In the event that the movements between different time zones are frequent and / or in the event that jet lag is perceived as a very limiting disorder, then one can think of intervening with a drug treatment. The latter is generally aimed at counteracting sleep disturbances caused by jet lag itself.
The drugs that can be used for the treatment of jet lag are short-acting benzodiazepines and benzodiazepine-like drugs.
Furthermore, even the intake of melatonin in small doses could be useful in countering the phenomenon of jet lag, especially when crossing many time zones.
Finally, in some cases, phototherapy can be used to restore the correct sleep-wake rhythm.
