Is a humidifier a gd idea for lodger's room?

[Willow33]

The room isn't damp - it's very well insulated with good heating. However we don't have a tumble drier. We dry our clothes in a space near our kitchen but there wouldn't be room for her to dry her stuff there. If she had a humidifier in her (large) room, would that help to dry her clothes?

We have found our dehumidifier more expensive to run than our tumble dryer - we really noticed it in our bills when we got the dehumidifier and used it to dry everything. We now tumble dry stuff that is tumble dryable and only use the dehumidifier for the rest (first choice obviously being drying stuff outside if the weather permits).
