Yawning can have a slight impact on heart rate, but the effect is generally temporary. When a person yawns, it often involves deep inhalation and stretching of the muscles, which can lead to a brief increase in heart rate. However, this change is usually minor and short-lived, as the body typically returns to its resting heart rate shortly afterward. Overall, yawning is more associated with factors like fatigue and boredom than with significant cardiovascular effects.
