Dangerous is something that is unforeseeable and associated with a high risk of injury. This does not apply to diving with your own air the way we do it! Of course, apnea diving is a sport. And you may hurt yourself if you do sport. That’s the way it is. Sometimes the ears may hurt or you may undercool,
Unfortunately, the media almost exclusively pictures apnea diving as an extreme sport. Of course, those activities that leave an unpredictable residual risk even for top athletes are the most spectacular ones. This often results in the distorted view that freedivers are entirely manic “danger freaks” and underwater kamikazes. The reality is that, as for any other sport, there are a few extremists her as well. Only two dozen out of every several million car drivers drive in circles at a speed of 300km/h as well. And just as for mountain climbing, enjoyment equals a dangerous expedition on a mountain of 8000 ms, only for a few mountaineers.
Freediving is a sport that, if you take safety rules to heart, dive within your limits and at least two people always enter the water together, has a very low risk of injury.
