What is a common effect of prolonged asbestos exposure?

Prolonged asbestos exposure is well-documented to lead to the development of respiratory diseases, making this the correct choice. Asbestos fibers, when inhaled, can cause significant damage to lung tissue. This can manifest in various health conditions, including asbestosis, lung cancer, and mesothelioma. Asbestosis is a chronic lung disease that results from scarring of lung tissue, leading to respiratory difficulties. Lung cancer associated with asbestos exposure often develops many years after the initial exposure, highlighting the long-term impact this material has on respiratory health.

The other options do not reflect the actual consequences of prolonged asbestos exposure. For instance, there is no evidence to suggest that asbestos exposure would improve lung function, increase energy levels, or enhance allergic reactions. Instead, the opposite is true, as prolonged exposure typically results in debilitating health issues, underscoring the seriousness of preventing exposure to asbestos in any form.
