For those who travels frequently overseas or across the country, what’s suffered is jet lag, also known as time zone change syndrome. What the adjustment of this time does is disrupts the internal body clock, this after crossing numerous zones. The body has a difficult time adjusting to rapid travel and the time adjustments. The internal body clock directs waking and sleeping patterns, along with behaviors such as digestion, appetite, bowel habits, blood pressure, and body temperature, which all becomes disrupted. Disturbed sleep patterns causes fatigue, headaches, muscle soreness, memory lapses, and impaired judgment.
