Nighttime Asthma

Nighttime asthma, also known as nocturnal asthma, is a type of asthma that is characterized by asthma symptoms, such as coughing, wheezing, and shortness of breath, that occur predominantly or exclusively at night. The exact causes of nighttime asthma are not fully understood, but it is believed to be related to several factors, including changes in hormone levels, circadian rhythm, and exposure to allergens or irritants that are more prevalent at night, such as dust mites, pet dander, and smoke.
