Normal Resting Breathing Rate for Adults

The normal resting respiratory rate for healthy adults is 12 to 16 breaths per minute.

Factors Influencing Respiratory Rate

• Age: Rates are higher in infants and children, gradually decreasing to adult levels by adolescence.
• Fitness level: Well-trained athletes often have lower resting rates (e.g., 8–10 breaths/min).
• Medical conditions: Fever, anemia, anxiety, lung disease, heart failure, and metabolic acidosis can increase the rate.
• Medications: Opioids, benzodiazepines, and beta-blockers may depress or alter breathing.

Clinical Note

A persistent rate outside the 12–16 range, especially when accompanied by symptoms like shortness of breath, chest pain, or altered mental status, warrants medical evaluation.
