6. Difficulty Sleeping
Sleep troubles are very common in nocturnal asthma, as the symptoms develop at night – usually after midnight or in the early hours in the morning. Sleep problems can also be seen in classic asthma and cough variant asthma.
There are a couple of reasons that explain the link between symptom aggravations during sleep. Firstly, airway resistance is increased during the night whether a person sleeps or not. Secondly, airway function is best before the onset of sleep and drops as sleep progresses. These changes can be found in healthy individuals, too, but the effects are greater in asthma sufferers.
