My son has recently discovered snorkeling and diving (by holding his breath, not scuba diving or anything). He can go at least 4m (13 feet) deep to pick up nice shells he sees on the sea floor.
My question is, is there any risk of him diving too deep?
Are there any statistics on snorkeling/diving accidents attributed to dives (ie not to shark attacks and such)?
This is an 8 year old who likes to test himself, and is still too young to be thinking ahead. If he is diving 4m now, it will become 5m soon enough. On the other hand, when coming up the buoyancy of his body is on his side, pushing him to the surface. In my own experience, you always have a little extra air to make it up.
From what I have read, freedivers face real risks of drowning (https://gue.com/blog/is-freediving-safe/) but these people go much deeper. Snorkeling websites only mention risks such as sunburn, getting run over by a boat or drifting too far. These are easily mitigated. He is never alone and we make sure he does not go too far out. He is diving in the Mediterranean so there is no real risk from marine life.
Even when help is near, if he has some accident someone will have to bring him up and to the shore. And even without drowning, (sea) water in lungs can be very dangerous. So I am trying to estimate the risks. I don't want to spoil his fun, when is was young I was allowed to dive as deep as could, but I was never much of a daredevil.
