Relevant experts said that the continuous high temperature easily causes the sensor to be too sensitive, and parking is protective, just to ensure passenger safety. In addition to the high temperature, small items carried by passengers in the air have also previously fallen into the air, causing the sensor to malfunction. Passengers should obey instructions and do not take things on a roller coaster.

Safety precautions for riding high-altitude play facilities:
(1) Roller coaster is not suitable for high myopia
"Although the eyeball itself buffers the pressure, too much intense activity may still cause excessive pressure in the eye and cause injury." Ophthalmologists explained that games such as roller coasters and crazy mice often occur in a short time. Sinking, turning, or even crashing, the process is very violent. While people are enjoying themselves, they can easily cause trauma to the eyes and cause inflammation. Especially in patients with high myopia, when performing such intense activities, it is easy to cause changes in eyeball pressure, and even severe cases may cause retinal detachment. 



(2) Toddler roller coaster is not suitable for cardiovascular patients
The roller coaster generates strong acceleration of gravity and centrifugal force, which can make the veins in the occupant's brain contusion and bleeding, and blood clots accumulate in the subdural space, forming a hematoma. Although the cause of spinal cord injury has not yet been fully ascertained, many experts believe that it is related to repeated repeated gravitational acceleration. Children's blood vessels and brains are not yet mature and are more vulnerable than adults. Zh
For normal people, occasionally riding a roller coaster once or twice will not have adverse effects, but it is very dangerous for people with vascular malformations and aneurysms. Because the head aneurysm will not affect the normal life of the patient without rupture, the patient will not feel uncomfortable, but once riding on a roller coaster, with the large amusement equipment turning, the head is facing down and the head Instant congestion, and the blood pressure of the head also rises instantly. This is very dangerous for patients with vascular malformations and aneurysms, and it is easy to have cerebral hemorrhage and even hemiplegia. The doctor reminds everyone that it is best to do a physical examination once a year to eliminate potential health hazards; for young people, don't play too many exciting games in a short period of time. 

(3) Patients with cervical spine should not ride a roller coaster
Although the roller coaster is exciting, not everyone can take it. Orthopaedic surgeons remind everyone not to ride a roller coaster if the cervical spine has been injured or the cervical spine is protruding and the cervical spinal canal is narrow. Don't drink any bubbles before getting on the bus, otherwise the roller coaster may spit when it reaches the highest point and then dives down. If you dive down from the highest point, you must shout if you are afraid, otherwise you will feel very uncomfortable if you are stuck in your chest. 

Expert report: "When the roller coaster ascends to a high point and suddenly dives down, the body will habitually throw forward, and the head will lean backwards, which will bring great impact to the body and may cause cervical disease. If the occupant tilts his neck aside while the machine is running, it is easy to sprain the neck muscles, ligaments, and even cause the cervical spine to break. "

If the occupant's cervical spine is not good, it is likely to worsen the condition. In severe cases, it may also cause trauma to the cervical nerve and spine. Orthopedic doctors remind everyone that when riding a roller coaster, your neck should be straight, your whole body should be up, your butt should not be too solid, you should hold the front armrest tightly with both hands, and your head and neck should be close to the head pad, so as to reduce the neck and waist. The impact force. 



(4) People with weak hearts should avoid roller coasters
Studies have shown that if a person with a heart attack rides a roller coaster, the excitement and stimulus brought by the roller coaster may lead to arrhythmia and may risk heart disease. Although the heart rhythm changes caused by the intense stimulation of the roller coaster are not a big problem for people with healthy hearts, they can be very dangerous for people with cardiovascular disease.

Dr. Kuschik of the Affiliated Hospital of the University of Heidelberg, Germany said: "People with heart disease and arrhythmia should not ride a roller coaster. The accelerated heart rhythm caused by the roller coaster may lead to heart disease, irregular heartbeat and sudden cardiac death. "

(5) You cannot ride a roller coaster during pregnancy
It is not advisable to do strenuous exercise after pregnancy. Even if it is just a week or so after you are pregnant, it is best to check it first to see if you are pregnant and have a healthy body. It is best to avoid irritating games.

Thrilling amusement programs can easily frighten infants and children, cause concussions, retinal damage and convulsions, and affect children's intellectual development and physical and mental health. If the child must play or the parent wants to exercise their guts, they should choose some slow-running, smooth-running electric car, bumper boat, swivel chair and other recreational items.
