Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Cold induced brown fat activity will be measured by skin temperature measures by means of infra-red thermography imaging and skin temperature.
15 healthy male winter swimmers and 8 healthy male non-winter swimmers (controls) will be included in the study.
