I don't know about you, but I have definitely fallen foul of the 'holiday cold' before, although it could be a coincidence I suppose.Lately 3 of us from the office travelled to London by plane, separately, yet we all caught the cold either while there or after arriving home. We do all work in the office and so might have passed it around in here, or could there be something in the air?Research has shown that you are 20% more likely to catch the cold on a flight (Wall Street Journal). Many people think it is because of the recycled air, but apparently you are more at risk before take off and after landing when the air circulation has stopped. The main culprit is low humidity at high levels of elevation as this allows viruses and bacteria to thrive. It also lowers our natural defenses as our nose and throats dry out.Top tips to try and remain healthy while flying include staying hydrated, washing your hands, wiping surfaces, avoiding use of the pillows and seat pocket. All very well & good, but not always practical or easy to do! So how about boosting your immune system before & after flying with healthy fruit and vitamins?We send lots of lovely fruit baskets out as get well gifts and we recently had a request for a Smoothie Gift Basket. Although we couldn't send the fruit in smoothie format as it would need to be kept refrigerated, we can provide the main ingredients. It gave me the idea of adding Smoothie Recipe Cards to our get well baskets, so as the recipient can make their own. What do you think of this idea?Here is a recipe I came across for a Cold/Flu Busting Coconut & Orange Smoothie by greenthickies.com:Orange and Coconut SmoothieINGREDIENTS– 1 Cup Orange Juice– 1 and a half Cups Coconut Milk– 6  Clementines (3 cups)– 2 teaspoons of  Ginger (raw or dried)– Juice of 2 LemonsOPTIONAL TO BOOST YOUR IMMUNE SYSTEM AND QUICKLY RELIEVE YOUR COLD– 2 Tablespoons Chia Seeds– 4 Tablespoons of  Manuka Honey– 20 drops of Echinacea– 4 Tablespoons of melted Coconut OilLet us know if you've tried it or what your cold fighting recipes are?
