Nocturnal cough asthma child12/18/2023 ![]() ![]() Hormones Can Also Affect Nocturnal Asthmaīecause of the circadian pattern, everyone - even people who don’t have asthma - experiences a drop in lung function at nighttime. So, you can imagine that’s why some patients may have worsening symptoms in the middle of the night,” says Chen. “The best lung function typically occurs around four in the afternoon and then it’s worse at four in the morning. Nearly every cell and tissue in the body, including the lungs, has its own pattern that not only syncs up with other cells that perform the same function, but also with other systems in the body. Some people may have worsening symptoms at night because asthma is associated with a circadian pattern - an internal clock - in their lung function, explains Chen.Īlthough the central circadian clock is located in the brain, scientists have established that the body has multiple internal clocks that are calibrated in different ways, according to a report published in the journal Cell. “A key difference is that with daytime symptoms, people can often carry on with their day, but when that occurs at night it can disrupt their sleep,” adds Chen.Ĭhildren can also have nocturnal asthma, and in those cases it’s not just the kids whose sleep is negatively impacted: The parents or caregivers end up with poor sleep, too, she adds. ![]() The frequency and severity of nocturnal symptoms usually correspond with daytime symptoms: If they are mild during the day, for instance, they tend to be mild at night, Chen says. These are often the same symptoms that can occur during the day,” says Chen. “Patients will report coughing, wheezing, shortness of breath, and chest tightness. Symptoms of nocturnal asthma are similar to those of daytime asthma, according to the Asthma and Allergy Foundation of America. “If people are having nighttime symptoms that are more than once or twice a week, we will want to keep an eye on them to make sure their asthma is being appropriately managed,” Dr. “About 30 to 70 percent of patients with asthma will report nocturnal symptoms at least once a month,” she says. Nocturnal asthma is surprisingly common, says Diana Chen, MD, clinical assistant professor and pulmonologist at Stanford Medicine in California. ![]() Keep reading to find out what you need to know about the symptoms, risk factors, and treatment of nocturnal asthma so you don’t find yourself coughing and wheezing in the middle of the night. But when asthma symptoms come on at night, the health impact is amplified: The fits of coughing and chest tightening may lead to sleep deficiency, which is associated with a higher risk of chronic conditions such as heart disease, diabetes, and depression. Just as with daytime asthma, nocturnal asthma can vary from mild to severe. If you have asthma and wake up coughing and wheezing at night, you may have a condition called nocturnal asthma, or nighttime asthma. ![]()
