Question

how does effective communication relate to health?
it prevents illnesses.
it makes it easier to argue with others.

it only helps in school, not in peoples personal lives.

Explanation:

Effective communication fosters positive interpersonal connections, which lowers stress levels—both of which are linked to better physical and mental health. The other options are incorrect: it does not directly prevent illnesses, it reduces conflict rather than making arguing easier, and it benefits personal lives beyond school.

Answer:

It improves relationships and reduces stress.
