Jet Lag

Why do we experience jet lag? A trip from New York to London requires traveling through five time zones. You may arrive at 9am, but your body thinks it´s 4am. Why? Circadian rhythms are responsible. They are internal biological changes that occur on roughly a 24 hour cycle; circadian rhythms are your biological clock. How do you reset your clock? Sunlight will reset your clock to local time, so get outside! But, it´s important to expose yourself to sunlight at the end of your sleep cycle, so your body interprets the light as dawn. Be sure to sleep on the plane.
