Also known as a disagreement disturbance, the jet lag is a sleep temporary problem that occurs when we change our time zone.
The jet lag occurs because the body continues synchronized with its habitual time zone at the zone it arrived. The United States Medicine National Library explains that the body responds to a 24 hours internal clock called Circadian Rhythm, which indicates our bodies when to sleep or wake up, and also obeys to environmental conditions, such as sun light. According to the Mayo Clinic, any individual who suffers this disturbance feels symptoms such as insomnia, concentration difficulty, somnolence and fatigue during the day, constipation or diarrhea, mood changes and general indisposition.
Some recommendations for preventing this problem:
- The jet lag lasts a couple of days. If you have an important event at your destination place, try to arrive with sufficient time in advance.
- Rest well before your trip, try to adjust your meal timetable and go to bed one hour early each night (if you travel west), or one hour later (if you travel east), gradually some days before.
- Sufficiently hydrate your body and avoid caffeine and alcohol.
- If in the location of your destination is night time, sleep in the airplane.
- Avoid exposure to bright light, because it influences on body rhythm.
- Although being tired, avoid sleeping when reaching your destination, and wait until night.
It is easier to perceive hourly disagreement when you cross a larger number of time zones, generally it is more difficult to travel east because it makes you feel as having “losing time”. There are also risk factors if you frequently travel or if you are an old adult.
