I don't necessarily agree with cycling at night, first because of the danger in cycling on dark roads, and second because as a cyclotourist you kind of want to SEE the countryside you're traveling through and meet its people. I've met cyclists who toured in Italy that suggested cycling during off-peak hours of the day, say from sunrise to 10 am and then from 6 PM to after sunset. During the peak hours they rested, stayed hydrated, napped, swam, visited places of interest etc... The only problem with this system is the fact that one has to set up camp for the night in the dark. I've found headlamps a good way to compendate for this. Otherwise, you can ditch camping alltogether and sleep in establishments (hotels, motels, B&B's etc.).
Cheers!
