She is a world champion in freediving (2006, 2008), world record holder (diving with constant weight without fins, 57 meters, Bahamas, April 8, 2008). Scientific research 

Natalia, together with scientists, took part in an experiment to study the language, echolocation and behavior of beluga whales in the White Sea. The possibilities of human survival in water under extreme conditions (in sea water - 2 °C) were also studied. Natalya swam and dived in the icy water, naked, holding her breath. During the experiment, she set a record for being under ice in ice water having a temperature of - 2 °C (salt water freezes at negative temperatures) - 10 minutes 40 seconds during the first hike. The documentary "On the edge" was filmed about this experiment by director Natalia Uglitskikh. Natalya was under water with an overhead environment for about 12 minutes, but with the possibility of one-time switching on in the breathing process. Top scores
