## What’s the Highest You Can Skydive From Without Oxygen?
Skydiving is an exhilarating sport that can be enjoyed by people of all ages and abilities. However, there are some limits to how high you can skydive from without using supplemental oxygen.
The highest altitude that a human has ever skydived from without oxygen is 135,908 feet (41,445 meters). This record was set by Alan Eustace in 2014. Eustace jumped from a helium balloon that was launched from Roswell, New Mexico. He freefell for four minutes and 19 seconds before deploying his parachute.
Eustace’s jump was a remarkable feat of human endurance and engineering. However, it is important to note that it was a very dangerous undertaking. Eustace could have easily died if his parachute had failed to open or if he had made a mistake during his freefall.
The vast majority of skydivers do not jump from altitudes as high as Eustace’s. Most recreational skydives take place at altitudes between 10,000 and 15,000 feet (3,000 and 4,500 meters). At these altitudes, the air is still relatively thin, but it is not so thin that supplemental oxygen is required.
Skydivers who jump from altitudes above 15,000 feet (4,500 meters) typically use supplemental oxygen. Oxygen is delivered to the skydiver through a mask or a nasal cannula. Supplemental oxygen helps to prevent hypoxia, which is a condition that can occur when the body does not receive enough oxygen. Hypoxia can cause dizziness, confusion, and even unconsciousness.
The highest altitude that a skydiver can jump from without oxygen depends on a number of factors, including the skydiver’s weight, fitness level, and experience. However, most skydivers who jump from altitudes above 15,000 feet (4,500 meters) use supplemental oxygen.
### Risks of Skydiving Without Oxygen
Skydiving without oxygen is a very dangerous undertaking. The following are some of the risks associated with skydiving without oxygen:
Hypoxia: Hypoxia is a condition that can occur when the body does not receive enough oxygen. Hypoxia can cause dizziness, confusion, and even unconsciousness.
Decompression sickness: Decompression sickness is a condition that can occur when a person ascends too quickly from a high altitude. Decompression sickness can cause pain in the joints, muscles, and chest.
Altitude sickness: Altitude sickness is a condition that can occur when a person ascends to a high altitude too quickly. Altitude sickness can cause headaches, nausea, and vomiting.
Death: Skydiving without oxygen can be fatal. If a skydiver’s parachute fails to open or if they make a mistake during their freefall, they could die.
### Conclusion
Skydiving is a thrilling sport that can be enjoyed by people of all ages and abilities. However, it is important to be aware of the risks associated with skydiving, especially if you are planning to jump from a high altitude. If you are not experienced in skydiving, it is important to seek instruction from a qualified instructor.
