When I travel, and especially when air travelling, l like to rely on morning prunes to keep me feeling regular. Before going to bed soak 2 prunes in a glass of water. Before eating breakfast in the morning, drink the water in the glass, and enjoy the soft prunes.
Dried fruit requires rehydrating before eating, especially if you are planning for the fruit to give a laxative effect. Without the overnight soaking the fruit rehydrates in your body, pulling the needed water from your system, and slowing down the movement through the digestive system.
Air travel itself dries the body. Be good to yourself. Help the body to cope with these changes by drinking generous amounts of water, practicing gentle yoga poses, and oiling the ears when you are home.
