Misconception: Contracting colds and sore throats are indications that an individual is in the exhaustion stage of selyes GAS model of stress
Contracting colds and sore throats (minor illnesses) are an indication that an individual is in the Resistance stage of GAS.
This is because during alarm reaction the body initially goes into a temporary state of shock and it's ability to deal with the stressor decreases. The body then goes into countershock
where adrenaline and cortisol are released into the bloodstream to energize the body an increase it's resistance against the stressor. If the stressor isn't dealt with in the Alarm reaction stage, the resistance phase is reached where the bodies ability to deal with the stressor rises above normal, all unnecessary physiological responses (digestion, reproduction, etc) are shut down and
as cortisol is still being released/in the bloodstream, minor illnesses such as the flu, colds, sore throats, etc start to appear. (Side note: High levels of cortisol for a prolonged period of time can suppress the functioning of the immune system, which is why minor illnesses start to appear in the resistance stage)
The exhaustion stage is reached if the stressor still hasn't been removed in stages 1 n 2. The bodies ability to deal with the stressor decreases.
Characterised by the presence of major illnesses ( heart disease, depression, extreme fatigue, etc)
Misconception: The only difference between neurohormones and neurotransmitters are that neurohormones are released into the bloodstream whereas neurotransmitters are released into the synaptic gap.
Edit: Attached a pic of Selye's General Adaptation Syndrome (GAS), also I just realised how much I miss psych
