FMD was significantly higher in the warm season than in the cool season when the measurements were performed in the same participants and the paired comparison was made.

Mean resting brachial artery diameter was significantly larger in the warm season than in the cool season. The maximal post-deflation brachial artery diameter was also significantly larger in the warm season than in the cool season. FMD that was calculated from the resting diameter and the maximal diameter was significantly higher in the warm season than in the cool season even if it was expressed as the relative value (%) or absolute value (mm). Twenty-one participants showed an increase of FMD in the warm season, although remained 6 participants exhibited paradoxical changes. No specific characteristics were found in these 6 participants.
The change of FMD value by the seasonal variation was not associated with gender, age, body mass index, smoking and alcohol consumption. There was no association between the seasonal change of FMD and the seasonal change of blood pressure in this study.
