Rhinitis - commonly referred to as rhinitis - can make it difficult for patients to function not only during the day, but also at night. A blocked nose can result in difficulty falling asleep, as well as causing the patient to wake up repeatedly during the night. There are, however, ways to keep a runny nose from interfering as much as possible with the patient's ability to sleep at night and, contrary to appearances, not only taking pharmaceuticals can help to achieve this effect.
