Bungee jumping

Bungee jumping (also spelled "Bungy" jumping)is an activity that involves jumping from a tall structure while connected to a large elastic cord. The tall structure is usually a fixed object, such as a building, bridge or crane; but it is also possible to jump from a movable object, such as a hot-air-balloon or helicopter, that has the ability to hover above the ground. The thrill comes as much from the free-falling as from the rebounds.

When the person jumps, the cord stretches and the jumper flies upwards again as the cord snaps back, and continues to oscillate up and down until all the energy is dissipated.

Safety and possible injury

Bungee jumping injuries may be divided into those that occur secondary to equipment mishap or tragic accident, and those that occur regardless of safety measures. In the first instance, injury can happen if the safety harness fails, the cord elasticity is miscalculated, or the cord is not properly connected to the jump platform. In 1986 Michael Lush died of multiple injuries after bungee jumping for a stunt on a BBC television programme[24] and in 1997, Laura Patterson, one of a 16-member professional bungee jumping team, died of massive cranial trauma when she jumped from the top level of the Louisiana Superdome and collided head-first into the concrete-based playing field. She was practicing for an exhibition intended to be performed during the halftime show of Super Bowl XXXI

Injuries that occur despite safety measures generally relate to the abrupt rise in upper body intravascular pressure during bungee cord recoil. Eyesight damage is the most frequently reported complication.Impaired eyesight secondary to retinal haemorrhage may be transient or take several weeks to resolve In one case, a 26 year old woman's eyesight was still impaired after 7 months Whiplash injuries may occur as the jumper is jolted on the bungee cord and in at least one case, this has led to quadriplegia secondary to a broken neck. Very serious injury can also occur if the jumper's neck or body gets entangled in the cord.[32] More recently, carotid artery dissection leading to a type of stroke after bungee jumping has also been described.All of these injuries have occurred in fit and healthy people in their twenties and thirties. Bungee jumping has also been shown to increase stress and decrease immune function
