Because of the strong stimulation or shock caused by the sudden weightlessness of the body during bungee jumping, the human body was suddenly in a state of high stress, and a large amount of adrenaline and other substances were secreted instantaneously, which would adversely affect the heart and other organs, making the heart beat faster and blood pressure increase. Therefore, people with a bad heart or high blood pressure were absolutely forbidden from bungee jumping.
In addition, some people with poor physical fitness, such as joint pain, lumbar vertebral disk protrusion, or fractured bones, couldn't participate in bungee jumping either.
People with eye diseases, such as glaucoma and deep myopia, shouldn't do bungee jumping either, because it would increase the intraocular pressure and could seriously cause retinal detachment when the head was down for a long time.
