64-day cold plunge challenge. Day 8 of 64

As I woke up early this morning, the temperature outside was a freezing 28 degrees. The water was even colder, measuring at 21 degrees, with a layer of ice. Upon observing the frost on the cars, roofs, and grass outside, I hesitated to take the plunge. To warm up, I performed three rounds of the Wim Hof breathing exercise, 30 push-ups, and 30 air squats. As I stepped outside, I felt the frigid air and began to worry about the risk of a heart attack.
