Scientists to look for ways of stress reduction for members of Arctic expeditions

19 june 2024

Researchers from Arkhangelsk will sail to Franz Josef Land for three weeks, where they are going to study the levels of stress hormones of the expedition participants in order to assess the adaptive reserves of the human body and make recommendations to people working in the Arctic.

People on board the Arctic Floating University will have their heart rate measured, their psychoemotional state monitored, and changes in hormone levels investigated. "We will record the initial hormone levels of people who went on the expedition, and will trace how these levels will change during the expedition," said Alexandra Yelfimova, an employee of the Federal Research Center for Integrated Arctic Studies of the Ural Branch of the Russian Academy of Sciences.

After processing the tests, questionnaires and laboratory data, scientists are going to release a list of practical recommendations for improving stress tolerance.

Participants of marine expeditions to the Arctic and people working in the North on a shift basis will be able to use these pieces of advice, yamal-media.ru reports.
