What should I do if my legs and feet are swollen while traveling?

Golden autumn is a good time for traveling, but due to long-term standing and walking during travel, your legs and feet may become swollen. The main reason for swollen legs and feet when traveling is that the lower position of the legs and feet, coupled with the gravitational effect of the earth, results in poor blood flow in the veins of the lower limbs. Blood accumulates in the veins for a long time, which increases the pressure on the blood vessels of the legs and feet, so the capillaries dilate and the blood The water penetrates through the blood vessel wall into the subcutaneous outside the blood vessel. If the subcutaneous water accumulates too much, it will cause swelling of the legs and feet. In addition, keeping the human body upright for a long time can also cause the body to secrete a large amount of aldosterone. This hormone can regulate the metabolism of water and salt, weakening the function of the kidneys in excreting water and salt, causing a large amount of water and salt to be retained in the body, causing edema in the legs and feet.

After standing and walking for a period of time, you should sit or lie down for a while and put your feet up. When riding in a car or boat for a long time, you should raise your legs to facilitate the return of venous blood in your legs and feet. Second, when traveling for a long time shopping or climbing, it is best to wear leggings with appropriate elasticity, or wrap a wide cloth belt around the calf several times and secure it with pins. Third, after traveling every day, scald your feet with hot water to expand the blood vessels in your feet and facilitate blood return. Fourth, if travel-induced leg and foot swelling occurs, you should lie down and rest for a day or two, and raise your legs and feet so that they are higher than the heart to facilitate blood return. It will get better in a day or two.
