Twisting cars for children? Twisting cars is a popular children's toy, but many parents are not sure whether twisting cars are suitable for children, whether it is good for children's growth. Today, along with Xiao Bian Learn about the impact of twisting cars on children! First briefly understand the simple introduction of the twisting car. The twisting car is a kind of plastic baby carriage. The three wheels have good stability and the price is not expensive, generally about 100 yuan. Parents can buy it with confidence and let their children play with twisting cars. But isn't it true that the twisting car is good for the kids? Let's take a look at a little story: When a child is 2 years old and 6 months old, he likes to play with a twisting car and does not stop for a whole day. When walking, the right leg is not very flexible and lasts for 5 or 6 days. For security reasons, take him to the Children's Hospital to check it and confirm that there are no serious problems. However, the doctor also made it clear that there is no problem with the bones. It should be a sprained knee joint and it needs a good rest. Therefore, twisting the car is not a bad thing. It is just a twisted car suitable for children of an age range. Twisting cars affect children 1, damage hearing. Noise is a major hazard to twisting cars. The correct way to ride a twisted car is to use the steering wheel to reverse the forward traction, which is slower and less noisy. However, in practice, the use of twisted cars is mainly for children under the age of three. Due to their age and small arm strength, they cannot drive the car forward by hand. Most children ride on twisting cars and use footholds. Sliding forward, the speed of the twisting car is greatly increased, but the resulting noise is also much higher. Currently, most of the twisted cars sold on the market are manufactured by the manufacturer in pursuit of low cost. The production materials of the wheels are made of ordinary hard plastic rather than elastic, sound, and PU smooth, even after the wear is smooth and smooth. The material used for the shoe wheel). Since the twisting car is an integral part of the plastic press molding, the body is similar to a speaker, and rapid gliding on an uneven surface (such as concrete floor, asphalt pavement, etc.) will generate a great noise. When children use twisting cars in the middle of the noise field, they are even more affected. A Swedish research institute said in a report that although the sensitivity of infants and toddlers to sounds is not yet accurately measured, there is evidence that children are more sensitive to sound than adults. The baby is in the golden stage of hearing development before the age of 3 to 5 years. Under this noise interference, the hearing sensitivity will be reduced by 30% to 50%, and severe hearing loss will result in stage deafness. 2, affect bone development. Since the twisted wheels are small, there is no damping device, and the gliding vibrations on the unsmooth ground will be extremely strong, which will cause the baby's young bones to be stunted. As most young children are riding on the twisted car with legs and feet on the ground, this sitting posture has a great influence on the young baby's skeletal development. Lightly sprained knees, hip joints, etc., and severe cases cause bandy legs. , feet outside the eight characters. 3, affect intelligence. Ear Cong Ming Ming is smart, if the baby's hearing is affected, will largely affect the intellectual development. 4, may damage the external genitalia of male baby. Since the twisting car has no brakes, it is also very dangerous for the baby to glide from the slope down to the high speed. The front of the seat of the twisted car is protruding, such as obstacles encountered in rapid gliding and the sudden drop in speed, it is easy for the boy's external genitals to be injured due to violent impact.
What is an air freshener [1]
Safe use of air fresheners [2]
Some families, in order to make the indoor air fresh, turn their attention to the chemical agent - air freshener. As everyone knows, these products not only emit a delicate smell to cover up the peculiar smell of the room, but also pose an invisible threat to people's health. This is because a large number of aerosols formed when spraying liquid air fresheners will also pollute the indoor air. The smoke generated by solid air fresheners such as sanitary incense and incense will also pollute the indoor air. It can be seen that no matter what kind of air freshener, it is not to eliminate the peculiar smell, but to "dilute" the peculiar smell by confusing people's sense of smell.
Some families use perfume spray to eliminate the odor of hygiene, or hang a "air fragrance paste" that can release fragrance for a long time. In fact, these methods are also undesirable. They also cover up another smell with one smell, which does not fundamentally eliminate the odor pollution in the bathroom. Moreover, perfume or aromatic paste is harmful to some skin allergies. It can cause allergic diseases, including asthma and skin diseases. In particular, most synthetic aromatics contain certain toxic organic compounds. Therefore, it is not suitable to cover up the peculiar smell of the toilet by spraying air freshener.
In order to reduce the harm of air fresheners to human body, the following points should be paid attention to:
â‘ do not overuse all kinds of air fresheners. The spraying amount shall be controlled when it is used occasionally, and the smell shall not be too heavy.
â‘¡ limit the scope of use. It's best to use it only in health, not in living room and bedroom.
â‘¢ during spraying, children, the elderly, pregnant women and the sick should be avoided.
