Asthma, a prevalent respiratory condition, can lead to breathing challenges for individuals across all age groups; however, it is commonly observed to develop during childhood. The intensity of an asthma attack may differ from person to person and even from one occurrence to another. Fortunately, the majority of asthma patients, approximately 95%, are able to manage their condition effectively without needing specialized medical attention. This is achieved through the use of inhalers and prescribed medication, which help control the symptoms associated with asthma.
Breathlessness
Breathlessness is a prevalent symptom experienced by individuals with asthma. It is primarily caused by the constriction of the muscles surrounding the airways, leading to a narrowing of the air passages. This narrowing can trigger bronchospasms and inflammation within the airways. As a response to this, the body produces mucus in an attempt to alleviate the situation. However, this reaction hinders the efficiency of the lungs in transferring oxygen to the tiny blood vessels present on the lung surface.
Asthma-Induced Coughing and its Impact on Sleep
Coughing is a common symptom experienced by individuals with asthma, and it often becomes more pronounced during the night. This night-time cough is typically dry, without the presence of mucus. Unfortunately, this persistent cough can disrupt sleep, leading to fatigue and decreased productivity the following day. Although the exact cause of increased coughing during the night remains uncertain, experts have put forth several theories.
One theory suggests that heightened exposure to allergens during the night may trigger and exacerbate asthma-induced coughing. Allergens such as dust mites, pet dander, or mold may accumulate in bedding, pillows, or bedroom furniture, causing irritation and inflammation in the airways. As a result, individuals with asthma may experience more severe coughing episodes at night.
Another explanation revolves around the impact of sleep position on asthma-induced coughing. It is believed that certain sleeping positions, particularly lying flat on the back, can promote the accumulation of mucus in the airways. This can further irritate the already inflamed airways, triggering coughing spells.
Hormones secreted during the night have also been suggested as a potential cause of increased coughing in asthma patients. While the exact mechanism is not fully understood, it is theorized that hormonal fluctuations during sleep may contribute to airway inflammation and increased coughing sensitivity.
To alleviate night-time coughing episodes, individuals with asthma are advised to raise the head of their bed. By elevating the head, gravity helps prevent the accumulation of mucus in the airways, thus reducing the frequency and severity of coughing episodes.
