If the hamster is coughing, wheezing, or anything like that... It is possible that they have a respiratory infection.
I would take them to the vet, and they might be able to help you.
If it is a respiratory infection.... the bathing sand that you might use contains dust. This can be very dangerous. You might want to switch the bath sand you are using so it doesn't happen again!
