Now people can hardly travel without a car, travel, business trips, work, all kinds of situations must take the car. However, some people tend to be very seasick, a car nausea uncomfortable. But some people can talk and laugh in the car, looking out the window to enjoy the beauty or take pictures. Why is it that some people get carsick and some people don’t get sick at all?
Why do some people get motion sickness and others do not have any problems at all?
A. Why do people get carsick?
Our ears are not only used for listening, acquiring and amplifying sound sources, but they are also involved in maintaining the balance of the entire body. The ear can be divided into the outer ear, middle ear and inner ear according to its anatomical structure. The vestibular apparatus of the inner ear is the body’s balance receptor and includes three pairs of semicircular canals and the ellipsoid and balloon sacs of the vestibule, which can sense stimuli in various specific states of motion. When a car starts, accelerates or decelerates, brakes, ships sway and lurch, elevators and airplanes lift and lower, these stimuli cause the vestibular ellipsoid and balloon sacs to produce deformational discharges in the capsule hair cells that are transmitted to and sensed by the center. These vestibular electrical signals are generated and transmitted within certain limits and time without adverse reactions, but there is a limit to the intensity and time tolerance of each person to these stimuli, and this limit is the dizziness threshold, and if the stimulus exceeds this limit, symptoms of motion sickness should occur.
In general, people with a low dizziness threshold have a relatively sensitive inner ear vestibular system and are therefore more likely to experience motion sickness and seasickness, while those with a high dizziness threshold have a relatively good tolerance for starting, braking or shaking. The tolerance of each person varies greatly and is influenced by factors such as vision, individual physique, mental state, and objective environment (e.g., air odor), in addition to genetic factors.
Second, how to avoid motion sickness
1.Distraction
Chatting, singing, playing games, etc. help to distract people with motion sickness, thus reducing the sensitivity of the vestibular receptors in the inner ear and alleviating discomfort.
2.Fresh air
Try to sit by the window to increase air circulation and improve the air quality in the car.
3.Avoid bad visual stimulation
When riding in a car, less looking out of the window, reading a book when riding in a car or boat is more likely to induce motion sickness, so close your eyes and rest can reduce the occurrence of motion sickness.
4, can not empty stomach in the car, and can not eat too full
Must not go to the car with an empty stomach, so it is easy to get carsick, but also can not eat too much, or gastrointestinal peristalsis digestion, more likely to produce motion sickness symptoms.
5, to maintain adequate sleep
The night before the car must maintain adequate sleep, when the appearance of motion sickness, it is appropriate to lie on their backs with their eyes closed, sitting with their heads close to the back of a fixed chair or object to avoid a larger swing, will be more comfortable.
6, buy suitable motion sickness medicine
Many people do not know some tips to prevent motion sickness, so the most common is to buy motion sickness medicine, but it is important to know is that motion sickness medicine is different, the duration of motion sickness medicine is also different, so you have to buy suitable motion sickness medicine according to the time you ride in the car.
Third, can I change my body type of motion sickness?
In fact, the body prone to motion sickness can be changed through targeted exercise. People who are prone to motion sickness will slowly adapt their vestibules to the motion environment in a car and gradually reduce the occurrence of overreaction if they ride regularly. We know that pilots are trained to train vestibular function through rotational movements during their training. In contrast, ordinary people can exercise their vestibular function through some gymnastic movements and exercise equipment for balance training.
People who are afraid of motion sickness can often participate in activities, especially sports that help regulate the body’s position balance, such as swings, slides, single and double bars, mat rolls and other sports that can improve the adaptability of the vestibular organs. You can also do more head turning, bending and turning and squatting to increase the tolerance of the vestibular organs.
