Final answer:
The statement regarding exercise having no positive effects on the nervous system is false. Exercise has multiple benefits for the nervous system, including improved mood, cognitive function, and stress management, contributing to overall wellness.
Step-by-step explanation:
The statement 'Exercise has no positive effects on the nervous system' is false. Physical exercise has numerous benefits on the nervous system, including improving brain function, reducing stress, and potentially lowering the risk for neurological diseases. Exercise stimulates the release of chemicals in the brain, such as endorphins and serotonin, which can improve mood and reduce feelings of depression and anxiety.
In addition, staying physically active is linked to better cognitive function and a lower risk of cognitive decline as we age. It can also enhance the body's ability to handle stress, as exercise contributes to the well-being of the nervous system by helping mitigate the adverse effects of modern day stressors. Well-being, or the state of being comfortable, healthy, or happy, is a dynamic concept and it involves multiple dimensions, including physical health, mental health, and social health.
For example, additional mental health benefits of physical exercise include improving body image and promoting positive self-esteem. Conversely, being sedentary is associated with an increased risk of anxiety and other mental health disorders. Therefore, exercise plays a critical role in achieving and maintaining overall wellness.
