help it

If a person is born of gloomy temperament they cannot help it. (Lord Chesterfield.)

My question is: they cannot help what?

Thank you.

"It" refers back to whatever was mentioned earlier. It simply means there is nothing I can do to change it.

I'm really pessimistic. I just can't help it.
He never gets anything down from the top shelf. He can't help it - he's only 4ft 6.
I drool whenever I see Johnny Depp. I can't help it. He's gorgeous!

They cannot stop themselves from being gloomy- they have to live with that aspect of their lives.
