Question
Frequent occurrences of redness on the right ear and cheeks without fever or other discomfort have been diagnosed as sympathetic nervous system excitement. What is sympathetic nervous system excitement? What diseases can it lead to? How should it be treated?
Answer
The sympathetic nervous system has an excitatory effect. When it is excited, it can lead to an increased heart rate, elevated blood pressure, dilated pupils, and difficulty in falling asleep. The sympathetic nervous system and the parasympathetic nervous system are a pair of nerves that mutually restrict and balance each other in the human nervous system. When a person is in an active, tense, or excited state, the sympathetic nervous system becomes excited, speeding up heart rate and respiration, and raising blood pressure to adapt to the demands of these activities; subsequently, the parasympathetic nervous system starts to become excited, inhibiting the excessive excitement of the sympathetic nervous system to restore the normal state of the body.
