They desperate for supplies?
As described earlier, wearing facemasks causing __hypoxic and hypercapnic state that __constantly challenges the normal homeostasis, and activates “fight or flight” stress response,an important survival mechanism in the human body [11], [12], [13]. The acute stress response includes activation of nervous, endocrine, cardiovascular, and the immune systems [47], [54], [55], [56]. These include activation of the limbic part of the brain,release stress hormones (adrenalin, neuro-adrenalin and cortisol), changes in blood flow distribution (vasodilation of peripheral blood vessels and vasoconstriction of visceral blood vessels) and activation of the immune system response' (secretion of macrophages and natural killer cells) [47], [48]. Encountering people who wearing facemasks activates innate stress-fear emotion, which is fundamental to all humans in danger or life threating situations, such as death or unknown, unpredictable outcome. While acute stress response (seconds to minutes) is adaptive reaction to challenges and part of the survival mechanism, chronic and prolonged state of stress-fear is maladaptive and has detrimental effects on physical and mental health.The repeatedly or continuously activated stress-fear response causes the body to operate on survival mode,having sustain increase in blood pressure, pro-inflammatory state and immunosuppression [47], [48].
