Interest rates?

I'm not into financial stuff so I'm a bit confused..
Housing has slumped, petrol prices are ridiculous.. and they want to put interest rates up..
How does that help? People are struggling already, isn't that hitting them while they are down?
Can someone pls explain in english how making ppl pay more for their mortgage when everything else is so expensive helps the economy?
