晕船症已被认为是运动病。其最常见的症状和体征是面色苍白、冷汗、恶心、呕吐、唾液变化及昏沉感。与传统经典概念不同的是最近发现无论是在转椅的实验条件下还是在实际晕船症中唾液分泌不是增加而是显著减少,晕船症的反应程度与唾液蛋白浓度呈正比。这些关系不但在已往而且在本次实验中均得到证 Seasickness has been considered as motion sickness. The most common symptoms and signs are pale, cold sweat, nausea, vomiting, saliva changes and drowsiness. Unlike traditional classical concepts, it was recently found that salivary secretion did not increase but decreased significantly in experimental conditions in swivel chairs or actual seasickness, and the degree of reaction to seasickness was proportional to salivary protein concentration. These relationships have been proven not only in the past but also in this experiment
