How to avoid problems caused by napping in a car (3)

Third, prolonged sitting can lead to poor blood circulation in the lower limbs. When passengers wake up from a long nap, their legs are often stiff and swollen. In extreme cases, they may suffer from varicose veins and even venous thrombosis, which can lead to major diseases endangering people's lives such as pulmonary thrombosis, cerebral thrombosis, and myocardial infarction.

Expert's advice: people with swollen legs can alleviate the symptom by taking a rest or raising their legs for a while. People with only one swollen leg should go to the doctor for timely treatment of possible venous thrombosis. If it is a long ride, passengers should try not to wear tight clothes so as to avoid poor blood circulation. In addition, they should drink enough boiled water to reduce blood viscosity and prevent thrombosis. They can also take such actions as curling toes, tiptoeing, bending feet, and turning ankles to ensure smooth blood circulation in the lower limbs.
