Saunas can indeed be beneficial for endurance athletes, as regular use can improve cardiovascular function and aid in muscle recovery. However, it's important to note that saunas can also cause dehydration, so it's crucial to stay hydrated before, during, and after sauna use.
Additionally, while saunas can help with muscle relaxation, it's worth considering other recovery methods such as foam rolling, stretching, and active recovery rides. These methods can also help reduce the risk of injury and improve overall performance.
In terms of managing atrial fibrillation (AF), it's great that you're taking a proactive approach by incorporating magnesium supplements, a healthy diet, and vitamins. It's also worth exploring other lifestyle factors that may contribute to AF, such as stress management and sleep hygiene.
Overall, saunas can be a valuable tool for endurance athletes, but it's important to approach them with a holistic view of health and wellness, considering all the factors that can impact performance and recovery.
