Physiological responses<\/h2>\n

How does the body react in stressful situations?<\/h3>\n

The body’s stress response process:<\/strong><\/p>\n

    \n
  1. The perception<\/li>\n<\/ol>\n

    The brain detects danger: when the brain (mainly the amygdala) detects danger or stress, it sends a signal to the hypothalamus, a central regulatory centre in the brain.<\/p>\n

      \n
    1. Hormonal activation<\/li>\n<\/ol>\n

      Secretion of adrenaline and noradrenaline: The hypothalamus activates the sympathetic nervous system, which stimulates the adrenal medulla (the inner part of the adrenal gland) to release adrenaline and noradrenaline.<\/p>\n

      Cortisol release: the hypothalamus stimulates the adrenal cortex through the pituitary gland to produce cortisol. This hormone helps the body cope with stress in the long term. <\/p>\n

        \n
      1. Physiological changes:<\/li>\n<\/ol>\n

        Heart and vascular system<\/p>\n

        Increase in heart rate and blood pressure: adrenaline and noradrenaline cause the heart to beat faster and blood pressure to rise to get more blood to the muscles and vital organs.<\/p>\n

        Blood vessel constriction: blood vessels constrict in some areas, such as the skin, while in other places, such as the muscles, they dilate to optimise oxygen and nutrient supply.<\/p>\n

        \"physiology<\/p>\n

        Respiratory system:<\/p>\n

        Faster Breathing: Breathing speeds up to get more oxygen into the bloodstream, which supports increased muscle activity.<\/p>\n

        Material exchange<\/p>\n

        Glucose release: cortisol and adrenaline increase blood glucose levels by releasing more glucose from the liver, which provides immediate energy for the muscles.<\/p>\n

        Muscle tension<\/p>\n

        Muscle activation: muscles tense up, ready to act, to react quickly to danger.<\/p>\n

        Sensory sharpening<\/p>\n

        Heightened perception: adrenaline and noradrenaline sharpen the senses, especially vision and hearing, to better perceive the dangers around you.<\/p>\n

        Digestion slowdown<\/p>\n

        Saving energy: the digestive system slows down as the body saves energy and focuses it on vital organs and muscles.<\/p>\n

        Immune system<\/p>\n

        Reducing inflammation: in the short term, cortisol reduces inflammation, but in the long term it can also suppress the immune system.<\/p>\n

        \"\"<\/p>\n

          \n
        1. Mental and emotional effects:<\/li>\n<\/ol>\n

          Increased alertness: the brain is ready to make quick decisions, which improves reaction time and survival chances.<\/p>\n

          Emotional tension: adrenaline and cortisol increase anxiety and tension, which can be helpful in the short term but exhausting in the long term.<\/p>\n

          Post-stress phase:<\/p>\n

          Activation of the parasympathetic nervous system: once the threat has passed, the parasympathetic nervous system starts to work to calm the body, slowing the heartbeat, lowering blood pressure and restoring normal digestion and other functions.<\/p>\n","protected":false},"excerpt":{"rendered":"
