Hamilton County launches instructor-led cold water immersion classes

Great Parks of Hamilton County rolled out a winter cold water immersion program at Campbell Lakes starting January 1, 2026, with sessions scheduled through March 1. The classes are led by trained staff and designed as a gradual, coached introduction to cold water exposure that prioritizes safety and participant comfort.

Program coordinator Joe Andrews described the sessions as intentionally slow progressions that start with knee-deep entry and move toward shoulder and neck immersion as participants feel ready. Each class combines guided breathwork with practical coaching on timing and safety, and instructors set short maximum immersion times to limit risk. Andrews recommends a three minute ceiling for any single immersion and notes that many participants receive most benefits at about one minute.

Organizers highlight several claimed benefits of regular cold exposure, including reduced stress, decreased muscle inflammation, and activation of brown fat for improved thermoregulation. Those potential benefits are presented alongside clear medical cautions. People with diabetes, neuropathy, Raynaud’s and similar circulatory or sensory conditions are advised to consult a doctor and may be asked to avoid the activity. Great Parks provides a list of contraindications and requires pre-registration for all classes to ensure staff can screen participants and manage class size.

On-site safety and recovery measures are built into each session. Warming tents are available after immersions and participants are offered snacks and drinks to help restore body heat. Instructors emphasize slow rewarming and continuous supervision rather than rapid, unsupervised exits from the water.

For the local community, the program fills a niche for guided winter outdoor wellness activities that balance challenge with risk management. The structured progression and breathwork coaching lower barriers for newcomers who want to try cold immersion without joining informal groups or attempting solitary dips. Requiring pre-registration and medical screening also creates a safer environment for people who might otherwise be uncertain about their personal risk.

If you plan to attend, pre-register with Great Parks to secure a spot, review the program’s contraindication list, and check with your healthcare provider if you have diabetes, circulatory or nerve conditions, or other chronic health issues. Dress in layers for after the plunge, follow instructor directions for timing and breathwork, and allow time to warm up in the provided tents. The classes provide a community-oriented, supervised way to test winter cold exposure while prioritizing safety and practical recovery.
