Airplane air is dry and uncomfortable. Drink at least 8 ounces of water for every hour you’re in the air–even if you don’t feel thirsty. If you wear contact lenses, clean them thoroughly before your flight, use eye drops in the air, and consider removing your lenses if you nap. In your carry-on pack a small bottle of lotion, lip balm, and a hydrating spray with essential oils to spritz your face with occasionally.
