Does Caffeine affect sinuses

Caffeine can have a mild impact on sinuses due to its vasoconstrictive properties, which may temporarily reduce swelling in nasal passages and improve airflow. However, this effect is not significant enough to treat sinusitis or other sinus-related issues. Additionally, caffeine can lead to dehydration, which might worsen sinus symptoms in some individuals. Overall, while caffeine may provide temporary relief, it is not a primary remedy for sinus problems.
