Long-distance travel, either by air or land, can lead to a small risk of blood clots. If you have cancer, had recent surgery, have abnormal blood clotting disorders, or are obese, you should be assessed by a healthcare practitioner before travelling. Tips to prevent blood clots during flights that every traveller can benefit from include: *maintain adequate hydration as it also encourages mobilization; *contract the calf muscles regularly or get up every 1-2 hours; *wear below-knee graduated Sigvaris compression stockings; and *choose an aisle seat when possible as it is proven to encourage mobilization. Talk to your pharmacist about ways to stay healthy while travelling.
