How to avoid problems caused by napping in a car (2)

Second, napping in a car may cause chest discomfort. When suddenly waking up from a long nap, passengers tend to get such symptoms as chest discomfort, breath shortness, and crushing pain, which reflect the functional abnormality of the heart.

Expert's advice: when traveling in a car, people can move their shoulders, massage upper limbs, or comb the hair down from the ear to the neck, so as to relieve tiredness, headache, and chest pain. Passengers who have suffered from chest pain should take nitroglycerin or medicine containing borneol in case of emergency.
