The effect of open mouth breathing, tachypnea, and hyperpnea, either alone or in combination, on sublingual and tympanic membrane temperature in healthy adults was investigated. Seventy-eight subjects maintained randomly assigned breathing patterns for 15 minutes. Temperatures were monitored immediately prior to and for 5 minutes following the breathing protocol. The only statistically significant finding (p less than .01) was a lower sublingual temperature with open mouth breathing. No significant changes in tympanic membrane temperature were seen.
