Intense or excessive exercise can lead to irregular periods or even amenorrhea (the absence of menstruation), but moderate exercise is generally beneficial for overall health and can help regulate the menstrual cycle. It's important for women to listen to their bodies and adjust their exercise routine as needed to support their menstrual health. Proper nutrition and rest are also important factors in maintaining a healthy menstrual cycle while training. **

However, it's important to allow for adequate rest and recovery between workouts to prevent overtraining, which can have a negative impact on the immune system. **

Eyesight can weaken due to a variety of factors, including aging, genetics, and lifestyle choices. As we age, the lens of the eye becomes less flexible, making it harder to focus on close objects. Genetics can also play a role in determining the strength of our eyesight. Additionally, factors such as excessive screen time, poor lighting, and not wearing proper eyewear can contribute to the weakening of eyesight over time. Regular eye exams and taking steps to protect our eyes can help maintain good vision. **

Ultimately, the impact of religion on individuals depends on how it is practiced and interpreted, and it can either weaken or strengthen people depending on the context. **
