Training for an Olympic event involves pushing your body to its limits, a process that ultimately strengthens your physical resilience. However, the same cannot be said for mental stress. Overthinking and excessive worry about competition can undermine performance and even impact your long-term health. While some mental stress can enhance cognitive function—helping you recall information or solve problems—when it spirals into anxiety and fear, it becomes detrimental. Chronic stress has been linked to a range of serious health issues, including heart disease, diabetes, and even premature aging. Understanding the balance between healthy and harmful stress is crucial for both athletes and anyone navigating the pressures of daily life.
