Is Title h1 tag in wordpress?

Google Core Update want us to use h1 tag. Is title h1 tag? Should i repeat the title name using h1 tag in the content?

Thank you

There is no need to repeat h1 with post Title.

so, when i write post title, i do not need to put h1 tag in the body right?

Means that wordpress, automatically put title as h1 tag too?

I am sorry, english is not my first language

WordPress automatically uses Post Title as h1.
