Asthma and anxiety are linked; adults with asthma have an anxiety prevalence rate of 34% (Weiser, 2007). To address if sleep could be the mediating factor that links these two diseases, we identified 132 papers from multiple databases that address this link. Based on the results and conclusions for each paper we were able to posit a directional link from asthma, through sleep disordered breathing (SDB), and finally leading to an increased risk of anxiety.
