Depends on whether you mean how deep or how far just beneath the surface, and if it's with breathing gear or by simply holding their breath. W/o breathing gear it's not really the water that sets the limit, but eventually the lack of oxygen. Lumping it all together staying shallower than 10 meters and shorter than one minute should be reasonably safe. If you're diving with breathing gear there are charts and computers that'll tell you what the safe limits are, but shallower than 10 meters is fairly safe even for that.

It depends on factors such as individual fitness, diving experience, and medical conditions. A depth of more than 30 meters (100 feet) without proper training, equipment, and supervision can be dangerous due to risks of decompression sickness, nitrogen narcosis, and oxygen toxicity. It's important to follow safe diving practices and consider factors like pressure, time spent at depth, and ascent rates to minimize risks.
