Cortisol has been thought to be inducing stress effects, however, the opposite may be true. Scientists argue that cortisol may very well be involved in the recovery phase of stress responses due to its late onset; several minutes to 25 minutes after the onset of a stressor. The neurochemical responsible for acute stress responses, e.g. fast beating heart is nor-adrenaline. References: Sapolsky et al., 2000; Oitzl et al., 2010
