Would you trust remote monitoring devices to provide accurate updates on your chronic health symptoms?
A study presented at the European Respiratory Society International Congress found that frequent nighttime coughing in adults with severe asthma correlates with increased symptom severity for up to three days. This contactless monitoring approach offers a potential new method for patients to track health trends beyond infrequent clinic visits.
Why it matters
Current asthma management often relies on subjective questionnaires or periodic check-ups that provide only limited snapshots of patient health. This research suggests that objective, continuous nighttime monitoring could provide early warning signs of worsening respiratory function.
In a pilot study of 13 adults with severe, uncontrolled asthma, researchers monitored patients for 9.5 hours nightly for one year. The findings showed a significant relationship between nocturnal cough frequency and worsening asthma symptom scores for up to 72 hours following an event.

Leiden University Medical Center
A research institution in the Netherlands that investigated the link between nocturnal coughing and asthma control.
European Respiratory Society International Congress
An international professional forum where findings on respiratory research and clinical advancements are shared.
The details
Researchers utilized the Albus Home contactless sensing device to track nocturnal coughing without the need for wearable sensors. By comparing these automated recordings against daily patient-reported symptom logs, the study identified that a higher frequency of nighttime coughing consistently preceded self-reported health declines. Because many patients struggle to quantify their own symptoms accurately, this passive technology aims to bridge the gap between doctor visits.

Health Landscape
This research contributes to a growing trend of using non-invasive digital health tools to improve asthma management. It highlights a shift toward continuous, objective tracking rather than relying solely on the episodic data common in traditional clinical care.
If you experience regular nighttime coughing, consider logging the frequency and duration of these events to share with your physician during your next consultation. Discussing these specific nocturnal patterns can help your doctor better assess if your current asthma treatment plan requires adjustment.
The takeaway
Nocturnal coughing is an objective marker that may signal impending asthma symptom flares. Track your nighttime sleep quality and cough frequency to facilitate more informed conversations about your care with your healthcare provider.
