I agree that you should keep the temps up, but insufficiant humidity is often a reason for an RI to develope. When we get congested, a nice hot shower will help our sinuses. If a snake has an Ri, and you take away their humidity, their nostrils will often close up with dry mucus, not allowing anything to flow. raising the humidity helps aid the creamy mucus to be breathed out, or wiped off.

My vet says that if your snake is making whistling or slight sounds while breathing but no mucus in the nose or mouth, then the sounds are caused by insufficient humidity, and creating a type of sinus infection. he raises Boas, and has been a reptile vet for 27 years.

Ways to increase humidity are by using a humidifier in the room, or spraying the inner walls of the enclosure.

I've been told to drop the humidity in the past, but the results were way slower and at times costly. Go see a good vet regardless.
