What is the purpose of subheadings in a text?

Subheadings serve to divide subject headings into more specific categories, allowing readers to navigate the text more easily. They help organize the content by breaking it down into manageable sections that focus on particular aspects of the overall topic. This structuring aids comprehension, as it provides clear indicators of what each section will discuss, making it easier for readers to locate information and understand the relationships between different ideas within the text. For instance, in a lengthy article about environmental issues, subheadings might categorize sections into topics like pollution, conservation efforts, and climate change impacts, making the structure logical and accessible.
