However, no information is available on acute, daily changing factors that could underlie these cardiac alterations.&lt;/p&gt;

&lt;p&gt;Aim: To estimate associations between daily heart rate characteristics (i.e. resting heart rate, autocorrelation and sample entropy) and allergy symptom severity and mood in adults with allergic rhinitis.&lt;/p&gt;

&lt;p&gt;Methods: Adults with a tree pollen allergy (n=82) self-reported daily symptom severity (score: 0-44) and mood (score: 0-4) in a mobile health application during two pollen seasons of hazel, alder and birch trees. Heart rate characteristics were extracted from daytime heart rate measurements (Mio Alpha 2 wristwatch; 1 Hz; &amp;gt;6 hours/day). Associations between heart rate characteristics and allergy symptom severity or mood (lag 0-2) were estimated using linear mixed effects regressions, adjusted for potential confounders with a random intercept for individuals.&lt;/p&gt;

&lt;p&gt;Results: The analyses included 3800 participant-days. A one-point increase in symptom severity was associated with an increase in resting heart rate of 0.07 (0.02 to 0.13)&amp;nbsp;beats per minute on the next day. A one-point improvement in mood was associated with a decrease in autocorrelation of -0.00027 (-0.00052 to -0.00001) and an increase in sample entropy of 0.0087 (0.0049 to 0.0125) on the same day.&lt;/p&gt;

&lt;p&gt;Conclusion: Results suggest that a higher symptom burden provokes the cardiovascular system (higher resting heart rate on the next day), while a better mood might be related to a healthier, more adaptable cardiovascular system (more irregular heart rate on the same day).&lt;/p&gt;
