Motion sickness symptoms

Unfamiliar shaking and speed when riding a vehicle such as a car, bus, or ship

It is an unpleasant symptom caused by changes.

Symptoms of motion sickness include aura, cold sweat, yawning, raw spit, headache and dizziness.

However, if this condition persists for a long time, painful symptoms such as stomach discomfort, heart pounding, nausea and vomiting may appear.

The balance of the body is maintained by three senses: balance, vision, and somatosensory (muscle movement).

For the sense of balance, the semicircular canals, which sense the inclination and position information of the body in the back of the ear (inner ear), and the vestibule, which senses acceleration, play important roles.

However, the inner ear is confused by the unpredictable and unpredictable shaking.

In addition, the field of view while riding moves sideways with the flow of scenery.

If the body is moving vertically but the eyeballs continue to move horizontally, the information in the inner ear and the visual sense will be different.

Therefore, the brain that receives this information is not well organized and gradually panics, the autonomic nervous system is disturbed, and the symptoms of motion sickness appear.

Environmental factors are the first cause of motion sickness.

It is easy to get sick if you start and stop repeatedly, or if the road is bad and shakes.

In addition, gasoline, the smell in the car, high temperature and humidity, reading in the car, etc. are also factors.

In addition, it is affected by anxiety and tension that you may get drunk, psychological factors such as feeling sick when you see a drunk person, and physical condition of the day such as overwork and lack of sleep.

Motion sickness is more common in children than in adults.

However, it is said that motion sickness is less likely to occur around the age of 3 because the autonomic nervous system is underdeveloped, and symptoms are more likely to occur in the growing age of 5 to 15 years, mainly in elementary and junior high school students.

Also, in adults, it tends to be more common in females than in males.
