[Effects of coffee on the respiratory system]

Area of Science:

• Pulmonology and Respiratory Medicine
• Pharmacology

Context:

• Coffee consumption is a widespread global habit with potential physiological effects.
• The respiratory system's response to coffee, particularly caffeine, is complex and warrants investigation.

Purpose:

• To explore the multifaceted effects of coffee consumption on the respiratory system.
• To examine coffee's role in conditions such as bronchospasm, chronic airflow obstruction (COPD), and bronchial cancer.

Summary:

• Coffee demonstrates a beneficial effect on bronchospasm.
• Its role in the development of COPD and bronchial cancer is suspected but not definitively proven, possibly linked to tobacco use.
• Coffee intake increases ventilatory frequency in healthy individuals and COPD patients.
• High maternal caffeine intake may increase the risk of neonatal apnea due to caffeine level fluctuations.

Impact:

• Provides insights into the dual role of coffee in respiratory health, highlighting both potential benefits and risks.
• Underscores the importance of considering lifestyle factors, like coffee and tobacco co-consumption, in respiratory disease etiology.
• Informs clinical understanding of respiratory regulation and potential interventions related to caffeine.
