The causes and consequences of yawning in animal groups
2022, Animal BehaviourCitation Excerpt :This includes the common, but incorrect, assertion that yawning functions to equilibrate blood oxygen levels. Through a series of elegant experiments on human subjects, Provine, Tate, et al. (1987) demonstrated that yawn frequency is not altered by breathing enhanced or decreased levels of O2 or CO2, and physical exercise sufficient to double breathing rates had no effect on yawning. It has therefore been concluded that yawning and breathing are controlled by different mechanisms, and it is now widely accepted in the scientific literature that respiration is not a necessary component of yawning (Corey et al., 2012; Guggisberg et al., 2010).

2021, Behavioural ProcessesCitation Excerpt :The second hypothesis is the respiration and circulation hypothesis, which states that yawning occurs when there is insufficient oxygen supply to the blood or brain, or when there is an oxygen decrease and carbon dioxide increase in the body (Guggisberg et al., 2010). However, this hypothesis was disproved by Provine et al. (1987). The third hypothesis is the brain cooling hypothesis, which suggests that yawning can change the blood flow inside the body or within the brain, resulting in a decrease in brain temperature (Gallup and Gallup, 2008).

2017, Neuroscience and Biobehavioral ReviewsCitation Excerpt :The effect was observed uniformly among mammals. It was reported in humans (Gallup and Church, 2015; Platek et al., 2003; Provine et al., 1987), non-human primates (Campbell and de Waal, 2011, 2010), canines (Romero et al., 2014) and rodents (Moyaho et al., 2015) alike. Contagious yawning has been shown to have no respiratory function (Provine et al., 1987).
