| Summary: | Yawning is an involuntary social behavior that occurs spontaneously and contagiously in most vertebrate species from embryonic stages to old age. The origin and function of this phenomenon are not clearly known and various stimuli can cause it. Our aim in this study was to investigate the factors effective in causing yawning in the northwest of Iran. This survey was conducted in the form of a questionnaire from 250 volunteer students and employees of Tabriz University of Medical Sciences and Tabriz University in northwest of Iran. The strongest motivation was seeing others yawning, and the others in order were fatigue, long and boring lectures, insomnia, and being in class; also the number of yawns in the morning was 8–10 AM more than other times. Insomnia caused by sleeping late is one of the five important causes of yawning caused by living in dormitories. According to the stimuli, it seems that yawning is probably responsible for the regulation of alertness during sleepiness, which, by extension, facilitates communication. |
