Scientists once thought humans could swim to a maximum depth of 30m on a single breath. Amber Bourke has gone deeper than 70m and physiology alone can’t explain why
Ten years ago, Australian Amber Bourke was in her early 20s and backpacking through Egypt when she discovered something astonishing about herself. In a little village on the Sinai peninsula she came across a place that taught “free diving” – underwater diving without any breathing apparatus – and decided to give it a try.
“I held my breath for four minutes and I dove to 18 metres,” says Bourke, who is the current women’s Australian pool and depth freediving champion. “And both of those things, I didn’t realise was possible.”
