Why it works: Light exposure is one of the prime influences on your body's circadian rhythm, regulating light exposure may help you adjust to your new location.
How it works: In general, exposure to light in the evening helps you adjust to a later than usual time zone (traveling westward), while exposure to morning light can help you adapt to an earlier time zone faster (traveling eastward). The one exception is if you have traveled more than eight time zones from your original time zone, because exposure to light in the early morning could be mistaken by your body as dusk. Conversely, evening light might be interpreted as dawn. So, if you've traveled more than eight time zones to the east, wear sunglasses and avoid bright light in the morning, and then allow as much sunlight as possible in the late afternoon for the first few days in your new location. If you have traveled west by more than eight time zones, avoid sunlight a few hours before dark for the first few days to adjust to the local time.
