Many people suffer from night asthma and wonder why there asthma symptoms get worse at night. Some people will be fine during the day and can control there asthma but at night they just can't seem to get control of their symptoms.
The reason behind night asthma has remained somewhat of a mystery. What experts do know is that at night certain bodily functions change at night including lung function which is at the lowest levels around 4:00 am. There have also been studies done recently that show that the hormone melatonin may contribute to night asthma because it may enhance airway inflammation.
Other factors are the common culprits including allergens such as pollen, dust, pet dander etc. As I mentioned earlier, airway inflammation can also increase at night because chemical levels in our body change at night. Other causes can be postnasal drip, heartburn and sleep apnea.
