As temperatures in Chicago plummeted to a biting 18 degrees Fahrenheit, a dedicated group of winter swimmers took the plunge into Lake Michigan, challenging the frigid conditions. Among them was George “Iceberg” Miller, who has made daily swims a winter ritual, embracing the cold as a means to enhance both physical and mental well-being.
Miller, originally from California, has transformed his relationship with winter from one of aversion to one of enthusiasm. Encouraged by a yoga instructor four years ago, he has since become a vocal advocate for embracing the cold. He aims to change perceptions about Chicago winters, stating, “I want Chicagoans, I want the Midwest, I want people to embrace winter, rather than complain about it.” His commitment to this cause has fostered a growing community of like-minded individuals.
On Sunday, during a winter storm warning that blanketed the city with snow, Miller was joined by his wife, Jesy Grose, and fellow swimmers Hayley Kimbrueh and Tom Ashman at Oak Street Beach. Together, they braved the icy waters for a 15-minute swim, despite the wind chill dropping to a chilling 5 degrees. “It feels really good after the first 30 seconds,” Miller shared, describing the initial shock followed by a surge of endorphins and adrenaline.
Research into cold-water immersion, including a review of 11 studies published in 2025, suggests that such activities can reduce stress and improve sleep quality, though no direct link between cold exposure and increased mood or immunity was established. For Miller, the immediate benefits were evident from his very first swim. “I felt sensations with mental clarity that I think it’s safe to say that I had never experienced before,” he explained.
Miller, who works as a leadership, career, and life coach, emphasizes the importance of confronting fear in a safe environment. He encourages others to embrace their anxieties, stating, “I feel afraid every single time, and that’s OK.” His approach seeks to help people step outside their comfort zones, using the cold plunge as a tool for personal growth.
Safety is a paramount concern for Miller and his group. He recommends that newcomers prepare gradually for the cold, ensuring their bodies are ready for the shock. “If individuals are unprepared, the experience is terrifying,” he cautioned, adding that unsafe conditions could lead to serious accidents. To ensure safety, Miller contacts the Chicago Police Department Marine Unit ahead of time, allowing them to monitor the group during their swim. Wearing neoprene boots and gloves is also essential, as these protect swimmers from potential injuries in the lake.
Miller’s commitment to safety extends to the community aspect of winter plunging. By never plunging alone, he has helped cultivate a supportive network of over 100 individuals who share his passion for cold-water swimming. “When I went into the lake for the first time, there were about five people that I knew of up and down the lake shore doing this,” he recalled.
After their invigorating swim, Miller and his fellow plungers typically head to a nearby sauna to warm up, completing the cycle of their unique winter ritual. This community’s efforts exemplify a growing trend of embracing winter activities rather than retreating indoors, showcasing a lively spirit that challenges the often-dismal perception of cold weather in the region.
