Because there is a carotid sinus with obvious fluctuations in the carotid artery on the outside of the human neck, if the collar is too tight or the scarf is tight, the neck The arterial sinus will be under pressure for a long time, and through nerve reflex, it will cause the blood pressure of the human body to drop, the heart rate to slow down, and the blood supply to the brain to decrease, and dizziness and nausea will appear.
When the normal human carotid sinus is compressed, the heart rate will slow down by about 5 beats/minute, Blood pressure will drop by 10 mm Hg. If it is a sensitive person, there may even be a reaction of cardiac inhibition or vascular inhibition, a sudden drop in blood pressure, and syncope such as cerebral ischemia.
This is why some people can’t wear clothes with high collars, and they feel uncomfortable when they put them on.
