On a long-haul flight, drink one litre of water for every six hours of flying. This will help you stay well hydrated, according to NASA’s aerospace medicine centre. Alcohol and coffee, on the other hand, interfere with sleep and leach moisture from your body. Avoid them!
An additional tip: take advantage of airport deli kiosks and purchase a large bottle of water in preparation for your flight — remember, staying hydrated on long flights should be a foremost priority.
What to Eat On Board
Granola bars, roasted nuts, dried fruit and whole-grain crackers are great snacks that won’t be confiscated at security. Your tummy (and wallet) will thank you once you’ve checked out the unhealthy and overpriced snacks being offered on board.
