It's difficult to diagnose a plant problem without seeing it so I can only offer some educated observations from personal experience. If the browning appears to be on the outer foliage, it may simply be a natural reddish brown coloration. Many arborvitaes develop this foliage discoloration when the weather turns cold but the plants green up again in the spring. Actually dried out and brown foliage - that which is crispy and breaks easily - is a problem caused by over/under watering, sunscald, or fertilizer burn. I hope the foliage is still supple rather than crispy when you bend it back!
