Nasal congestion often worsens at night due to several physiological changes, NDTV reports citing Dr Subrata Das. Lying down increases blood flow to the nose, while allergens like dust mites in bedding and dry indoor air can irritate nasal passages. The body's natural circadian rhythm also causes nasal inflammation to peak in the evening. Dr Das advises identifying triggers such as pet dander or mould. Simple remedies include using a humidifier, elevating the head, and washing bedding in hot water. If congestion persists with facial pain or fever, it may signal sinusitis needing medical attention.
