Irish motorists were warned today that they could be at risk from deep vein thrombosis (DVT) on long trips.
The RAC Foundation said DVT could affect not only air travellers, but anyone in the confined space of a family car for a prolonged period.
A French cardiologist has published a report saying any journey of more than four hours carried a risk of pulmonary embolism or blood clots - irrespective of the means of transport as anyone who remains seated for a long period in the same position risks having the veins in their feet and legs restricted.
Mr Robert Taylor, Managing Director of RAC Ireland advised motorists intending to take long journeys to give themselves plenty of time to allow for short breaks every couple of hours.
Other general advice issued by RAC Ireland today includes getting plenty of fresh air and wearing loose comfortable clothing. Seat exercises like ankle rolls and toe pointing should be done during the during and both drivers and passengers should drink plenty of water.
Mr Taylor added that the above advice would also help prevent drivers from getting tired behind the wheel, making for a safer journey all round.
