What are the hazards of twisting cars to young children

A twist car is a common children's toy. It has good stability. Children can exercise their bodies and improve their balance ability by riding it every day. However, parents should also understand that if they always play such a twist car, it will have a certain impact on their health. It will damage their hearing, easily affect bone development, and also have a certain impact on their intelligence. Therefore, they should not play such a twist car too much.

1. Damage hearing .

Noise is the main hazard that twisting cars bring to children. The correct way to ride a twisting bike is as shown in the picture below. It uses the twisting of the steering wheel to generate forward traction. This method generates a slower speed and less noise.

But in reality, the main users of twisting cars are children under three years old. Due to their young age and weak arm strength, they cannot drive the car forward with their hands. Most children ride on the twisting car and slide forward with their feet. This method greatly increases the speed of the twisting car, but the corresponding noise also increases a lot. Most of the hoverboards sold on the market are made of ordinary hard plastic instead of PU (the material used for roller skate wheels) which has good elasticity, low noise and remains smooth even after wear in order to keep costs low.

Since the twisting car is a whole body formed by plastic compression, the car body is similar to a speaker. When it slides quickly on an uneven surface (such as concrete, asphalt road, etc.), it will produce a lot of noise. Children are in the center of the noise field when using twisting cars and are more seriously affected.

A Swedish research institute said in a report that although it is currently impossible to accurately measure the sensitivity of infants and young children to sound, there is evidence that children are more sensitive to sound than adults. The golden period of hearing development for babies is before the age of 3-5. Under the interference of noise, hearing sensitivity will be reduced by 30%-50%, and severe cases will cause temporary deafness.

2. Affects bone development .

Since the wheels of the twisting cart are small and have no shock-absorbing device, the vibration when sliding on uneven ground is extremely large, which can cause poor development of the baby's tender bones. Since most young children sit on a tricycle with their legs apart and the soles of their feet on the ground, this sitting posture has a great impact on the development of the baby's delicate bones. In mild cases, it may sprain the knees and hip joints, while in severe cases, it may cause bow legs and feet to turn outward (there are also examples online that directly explain foot deformations caused by riding a tricycle). Yishi sprained his knee last time, and this may be the reason.

3. Affects intelligence .

A person with sharp ears and eyes is smart. If the baby's hearing is affected, its intellectual development will be affected to a great extent.

4. Affects personality .

Children who are in a noisy environment for a long time will become anxious, irritable, rebellious and restless (I have reservations about this, as the time a child spends playing with a twisting car probably does not meet the standard of "long term").

5. It may damage the external genitalia of male babies .

Since twisting cars have no brakes, sliding down a slope at high speed is also very dangerous for babies. There is a protrusion in front of the seat of the tricycle. If it encounters an obstacle while sliding quickly, the speed of the car will drop suddenly, which can easily cause the little boy's external genitalia to be injured due to the violent impact.
