The 75 Hard Challenge can be a powerful tool for improving mental health, as it emphasizes consistency, discipline, and self-improvement. By committing to the daily habits of the challenge, participants can develop a stronger sense of self-control and resilience. The requirement to exercise twice a day helps boost endorphin levels, which can reduce stress and improve mood. Additionally, the daily reading habit encourages personal development, while the strict diet and hydration goals can contribute to overall well-being. The challenge can also serve as a structured way to manage anxiety and build a positive routine.
