Hard nipples?

I have a two week old and we ebf and it's starting to get a little easier except any time I get a tiny bit chilly my nipples get hard and it HURTS. Like bad. I use lanisoh nipple cream and it helps soreness from her sucking but nothing is helping the pain from hard nipples. Is this normal? And does it get better? I'm currently keeping my house at 76 degrees so my nipples won't get hard 😅
