As a phenomenon: Ramadan fasting improves olfactory performance

Abstract Objective The present study objectived to investigate the influence of Ramadan fasting (RF) on olfactory function. Methods Sixty‐two participants were included in the current prospective study. The odor threshold and identification performances were determined by using the Connecticut Chemosensory Clinical Research Center (CCCRC) test initially (day 0) and on the first and last day (30th) of RF. Body weight (BW)s were measured initially and at the end of the study. The results were analyzed statistically. Results The average of baseline and last‐day BWs were 78.38 ± 12.96 and 78.36 ± 12.39 kg, respectively. No significant difference was determined in terms of BWs (p = .932, p > .05). In the evaluation of CCCRC test outcomes, significant differences were observed in the scores of butanol thresholds (p = .0001), odor identification (p = .0001), food‐related odors identification (p = .0001), and the number of normosmic individuals (p = .0001) at different times (p
