An inevitable result of traveling long distances from your home, jet lag doesn't have to get you down. Sure, your body can naturally adjust (eventually), but it's possible to make this work for you. For example, enjoying a late dinner before taking advantage of the nightlife or attending a concert on the East Coast is even easier when traveling from the west. Similarly, flying from the East Coast to Hawaii may mean you naturally wake before dawn, providing extra time to get ready for an early morning hike or to head somewhere and watch the sunrise, something you may never get up to do in your hometown.
While jet lag could be avoided, you just never know 'til you get there. Save yourself some time and look up a couple things to do on vacation during the earlier mornings or in those extra hours before nightfall, depending on which way you've traveled, before you leave home so you're not scrambling upon arrival. Do you ever plan activities on vacation to maximize those waking hours, odd as they might be?
