==Overview==
==[[Nocturnal asthma overview|Overview]]==
Nocturnal worsening of asthma is very common finding in asthmatics. The pathophysiology of nocturnal asthma is closely associated with the chronobiology and the science of biologic processes that have time-related rhythms. Hence, understanding the circadian rhythm is important to interpret the changes in pulmonary function that occurs in sleeping asthmatics. A large population based study reported dyspneic episodes without therapy in asthmatics occurred between 10 P.M. and 7 A.M.<ref name="pmid8494197">Martin RJ (1993) [http://www.ncbi.nlm.nih.gov/entrez/eutils/elink.fcgi?dbfrom=pubmed&retmode=ref&cmd=prlinks&id=8494197 Nocturnal asthma: circadian rhythms and therapeutic interventions.] ''Am Rev Respir Dis'' 147 (6 Pt 2):S25-8.

==Asthma and sleep apnea==

It is recognized with increasing frequency, that patients who have both [[obstructive sleep apnea]] and [[bronchial asthma]], often improve tremendously when the sleep apnea is diagnosed and treated.<ref name=sleep_anpea1>{{cite press release | title = Breathing disorders during sleep are common among asthmatics, may help predict severe asthma | publisher = University of Michigan Health System | date = May 25, 2005 | url = http://www.med.umich.edu/opm/newspage/2005/asthmasleep.htm }}</ref><ref name="pmid18849401">Teodorescu M, Consens FB, Bria WF, Coffey MJ, McMorris MS, Weatherwax KJ et al.
