The Federal Association of Health Consultants said that sitting long while traveling raises the risk of blood clotting in the legs, where the lack of movement for a long time causes blood clots in the legs and clogged veins, pointing out that some blood masses may reach the lung causing a life-threatening lung stroke.

The German association added that this risk particularly threatens patients with heart and varicose veins and people who tend to tend to blood clots, as well as those who had previously had a stroke in the leg or a stroke in the lung.

These people should consult a doctor before traveling by plane or before long trips by car to see if it is necessary to wear compression stockings or take certain injections.

To prevent blood clotting during travel should rise from time to time, walking to move blood in the legs taking into account the wearing of wide and loose clothing, as well as a lot of drinking liquids such as water, herbal tea and diluted juices.
