The study authors fitted participants with wearable devices that tracked air flow in and out of their noses over 24 hours of normal activity. They followed 31 people with self-reported normal olfaction and 21 participants born without a sense of smell (known as “congenital anosmics”). They found that both smellers and non-smellers had similar breathing rates, but that, while awake, smellers’ respiratory patterns included an average of 240 additional inhalation peaks per hour, compared with non-smellers.
