A cough caused by postnasal drip related to sinusitis is more prevalent at what time of day?

A cough caused by postnasal drip related to sinusitis is particularly prevalent at night due to the body's position during sleep. When lying down, mucus can accumulate in the throat more easily, leading to irritation and triggering a cough reflex. This is exacerbated by the relaxation of throat muscles while sleeping, making it more challenging for the body to clear mucus effectively. As a result, individuals with sinusitis frequently experience a worsening of their cough at night as they attempt to sleep. This pattern aligns closely with the mechanics of postnasal drip and its effects on the airways.
