The leading factor in the appearance of motion are straight-line acceleration, many times exceeding the thresholds irritation otolith apparatus.
It is generally accepted otolith theory of motion sickness. Mechanical factors of motion sickness and cause their forces not only affect the vestibular system, but also on interoceptive apparatus all moving bodies, which increases vegetative reactions that occurred in response to irritation otolith apparatus. Undoubtedly, in the development of the motion play a role and processes with abundant afferention in the bark of the big hemispheres of a brain. Motion sickness can occur at a conditioned reflex mechanism (when looking at a rough sea).
Symptoms of motion sickness diverse: dizziness, headache, fatigue, increased secretion of saliva, cold sweat, nausea, vomiting. After vomiting occurs short-term improvement. At long tossing in some individuals may sometimes come and loss of consciousness. Among flight crews and teams ships travel sickness occurs much less frequently, as in the roster are selected people with sustainable vestibular system, and for the seamen produces immunity to the factors of motion sickness. Of pharmacological agents are effective, Aeron, diphenhydramine.
