Hot milk: Milk helps to relax everyone, from babies to adults. It also soothes the stomach after all those in-flight drinks.

Hot chocolate: Another popular way to prepare the body for sleep and surprisingly healthy, too, is hot chocolate as it is full of anti-oxidants.

Chamomile tea: A gentle sleeping aid which relaxes the body naturally, as it contains no caffeine and is a great herbal drink before going to bed. For some, a nice glass of red wine will do the trick!
