Which of the following can aid in thinning thick mucus aside from a mucolytic such as Mucinex?

Drinking more water and fluids is indeed an effective way to help thin thick mucus. When the body is well-hydrated, mucus becomes more fluid and less viscous, making it easier to expel. Adequate hydration is essential for maintaining optimal respiratory function and can significantly alleviate symptoms associated with conditions like colds or allergies, where mucus buildup is common.

While options such as using a humidifier, taking hot showers, and consuming spicy foods can also assist to some extent in relieving congestion and promoting mucus clearance, drinking water specifically works directly to increase fluid intake in the body, thereby enhancing mucus consistency more effectively. Hydration is fundamental, as it supports the body's overall function and the health of mucous membranes, ensuring that secretions remain less thick and easier to manage.
