Laughter-induced asthma: It’s no joke

25.05.2005


More than half of people with asthma report that their symptoms are brought on by laughter, according to a study to be presented at the American Thoracic Society International Conference on May 24.



The study of 235 patients with asthma found that 56% had laughter-induced asthma (LIA). Asthma that is triggered by laughter doesn’t seem to cause more asthma flare-ups requiring emergency room visits or hospitalizations compared with other types of asthma, according to study author Stuart Garay, M.D., Clinical Professor of Medicine at NYU Medical Center in New York. "But patients did report that during times when their asthma is well controlled they can laugh for longer without getting asthma symptoms. That suggests that laughter-induced asthma may be a sign that a person’s asthma isn’t as well controlled as it could be. People with asthma should be allowed to laugh."

Nobody knows how laughter brings on asthma, but it might involve hyperventilating, Dr. Garay said. He noted that exercise was the only trigger more common in people with laughter-induced asthma compared with asthma not induced by laughter (61% of people with LIA vs. 35% of asthma patients without LIA).


Dr. Garay was struck by how common laughter-induced asthma is. "It’s as common as some of the most well-known asthma triggers, such as grasses, trees, pollen, fumes and odors, and it’s even more common than dust mites, allergy to animals and molds," he said. "It’s a little-appreciated frequent trigger."

The study found that the most common symptom in patients with laughter-induced asthma was coughing, which generally starts within two minutes. The next most common symptom was chest tightness.

How much laughter can set off breathing problems? "It depends on the patient," Dr. Garay said. "For a majority of patients, mild laughter or even a chuckle will set off coughing. For others, laughing hard will bring on asthma symptoms."

Im Focus: Neutron star merger directly observed for the first time

University of Maryland researchers contribute to historic detection of gravitational waves and light created by event

On August 17, 2017, at 12:41:04 UTC, scientists made the first direct observation of a merger between two neutron stars--the dense, collapsed cores that remain...

Im Focus: Breaking: the first light from two neutron stars merging

Seven new papers describe the first-ever detection of light from a gravitational wave source. The event, caused by two neutron stars colliding and merging together, was dubbed GW170817 because it sent ripples through space-time that reached Earth on 2017 August 17. Around the world, hundreds of excited astronomers mobilized quickly and were able to observe the event using numerous telescopes, providing a wealth of new data.

Previous detections of gravitational waves have all involved the merger of two black holes, a feat that won the 2017 Nobel Prize in Physics earlier this month....

Im Focus: Smart sensors for efficient processes

Material defects in end products can quickly result in failures in many areas of industry, and have a massive impact on the safe use of their products. This is why, in the field of quality assurance, intelligent, nondestructive sensor systems play a key role. They allow testing components and parts in a rapid and cost-efficient manner without destroying the actual product or changing its surface. Experts from the Fraunhofer IZFP in Saarbrücken will be presenting two exhibits at the Blechexpo in Stuttgart from 7–10 November 2017 that allow fast, reliable, and automated characterization of materials and detection of defects (Hall 5, Booth 5306).

When quality testing uses time-consuming destructive test methods, it can result in enormous costs due to damaging or destroying the products. And given that...
