Hadi,
If you are talking about bright sunlight the answer is yes, but
you have nothing to worry about under normal incandescent illumination.
Actually, it is best to coat paper under a low wattage incandescent bulb
because you can see the sensitizer on the paper and that helps you get an
even coating. The paper itself is not really light sensitive until it is
dry. By the way, don't use heat to dry for it will result in a loss of
contrast. Let it dry naturally or use a fan.
