Photo Gallery: Cold PlungeBy Admandy / January 8, 2025 / Getting seriously cold. January 2024 with a wind-chill of 15 F. My first experience in cold water. Lake Michigan, Spring Break 2015. Shoveling in shorts. Outdoor exposure is also beneficial, but cold water has about a 3x multiplier. Joan urged me to strike this pose… I may have done it without her encouragement.
