Method
In this study, participants with toenail fungus will undergo a heat treatment using a controlled water bath system. Each participant's affected foot will be immersed in a container filled with sufficient water to fully cover their toenails. A sous-vide immersion circulator will be utilized to maintain the water temperature at exactly 44 degrees Celsius throughout the treatment duration. The foot will be submerged for 20 minutes. When finished, the feet and toes should be thoroughly dried with paper towels.
