Abstract
The effects of cold-water immersion (CWI) and intermittent fasting (IF)/ketosis have been extensively investigated independently. However, the primary objective of this study is to explore potential links between the two. Cold-water immersion is known for diverse benefits, such as aiding athlete recovery, enhancing cognitive function, and contributing to mental health improvement. This research aimed to assess ketone levels in six individuals (four males and two females) across various fasting states (8- and 12- hours, and 8-hours with a ketone ester supplement), exposing them to a 15-minute head-out immersion at 50ºF (10ºC). Although no significant differences in ketone levels were observed across the three trials, this pilot study, involving six participants, unveils potential trends between CWI and capillary ketone levels during a fasted state. Additionally, the introduction of a ketone ester supplement resulted in elevated ketone levels. It is important to note that further research and data are required to draw conclusive insights into the observed 38% increase in our pilot trial.
