Online published on 8 February, 2019. Abstract Introduction Based on Iranian traditional medicine, foods are classified under two groups: hot-natured and cold-natured. The present study, therefore, undertakes to determine the effects of hot-and cold-natured foods on the vital signs in the human. Method The study was quasi-experimental and the participants in the experiment were 60 students, in Gonabad University of Medical Sciences, who had, during summer semester, been selected and depending on their temperament placed into three sample groups at duration 3 weeks, each of them having their own dietary program: one to be served with hot-natured foods for their meals, one with cold-natured foods, and the one as reference group with mixed undifferentiated foods. The blood pressure, heart rate, respiratory rate and body temperature were measured pre-and post-intervention. Due to the normality of the data distribution, the gathered data were analyzed using SPSS software program (Ver. 19) and paired T-test and ANOVA in a meaningful level of p<0.05. Results According to ANOVA, the students of the three groups showed no significant differences in demographic characteristics and medical examinations pre-and post-intervention (P>0.05). The systolic (p=0.031) and diastolic (p=0.020) pressures significantly decreased in hot-natured group and the heart rate significantly increased (p=0.001). The vital signs indicated no significant differences between the three groups pre-and post-intervention (p>0.05). Conclusion Consumption of hot-natured foods for three weeks decreases the systolic and diastolic pressures and increases the heart rate. Top Keywords Hot-and cold-natured foods, Vital signs, Human.
