why stress makes asthma worse

Scientists have documented a range of stressful events that have been associated with asthma symptoms. These include school exams, public speaking, family conflict, public disasters, and exposure to violence. Stress may directly affect the body or cause people to manage their asthma less effectively.

stress and anxiety can cause physiological changes that may provoke an attack. These strong emotions trigger the release of chemicals, such as histamine and leukotrienes, which can trigger the narrowing of your airway.

During periods of stress and anxiety, people might forget to take their asthma medications, making an attack more likely, Gergen says. Stress-related hormones also reduce the body’s ability to fight off colds and other respiratory infections. “Viral infections are very important causes for triggering asthma,” Gergen says.
