I agree with John. Let it acclimate first. Keep checking the MC until it has stabilized.
The acceptable moisture levels in a house range from 30% RH to 70% RH. At either extreme, health problems can begin to occur. At the higher extreme, mold can start to grow. If the average humidity in your house is 70% then the RH in your bathroom and kitchen are probably higher and your bedroom may be higher by morning each night. I would look at ways to try and get it down at least 10%. If the outside humidity is lower then some ventilation will help.
Someone I consider a master woodworker once told me that a master woodworker is not someone who never makes mistakes. He is someone who is able to cover them up so that no one can tell.
