Temperature

Can anyone please tell me if they’ve ever had there temp set to 75 and there baby was ok? We have central hair and our baby is one month old. My husband doesn’t want to lower the temperature because he gets cold really easily. It’s not warm in our house , but I still worry as I heard the best temp for babies is between 68-72 because of the risk of SIDS. The doctor didn’t push the issue to him today she just said it’s important the air be well circulated but still. I worry all the time about sids and am curious if anyone has ever gone above the 68-72 rule. Thanks.
