How many meters do people usually dive to without harming their health?

It's no problem to dive 6 meters with your bare hands. The eardrum will hurt a little at first, so get used to it. People who exercise regularly will have no problem diving to 10 meters with heavy objects, and then diving is not a matter for non-professionals; At present, few professional divers in the world reach the dive of 306 meters, and this limit is still being broken by future generations; However, there are also some professional divers who dive to a depth of 200-300 meters and die heroically. Therefore, non-professionals should not try to go below 100 meters, or even below 50 meters, otherwise their lives will be in danger.
