"The most immediate effect we see in a stressful situation is a surge of adrenaline causing an increase in heart rate, blood pressure and breathing. This is your fight-or-flight response, and it's designed to prepare you to address the challenge you are facing. Within about 30 minutes of this rapid response, you'll also experience a rise in cortisol, often (somewhat reductively) known as the stress hormone."
"Again, this is very useful in supporting the fight-flight response because it regulates blood pressure, suppresses inflammation and increases the availability of blood sugars to increase energy. It can be useful to stop coping strategies that aren't helpful'. Photograph: Posed by model; Ekaterina Goncharova/Getty Images"
"This was all very useful centuries ago when most of what life threw at us was physical challenges. But now it's fairly rare that we need to literally run away from or physically fight the source of our stress, and very easy for us to start worrying about someone being mean to us on the internet, or spend hours ruminating on an argument with our partner."
Stress rapidly increases adrenaline, raising heart rate, blood pressure, and breathing as part of a fight-or-flight response. About 30 minutes later, cortisol rises and helps regulate blood pressure, suppress inflammation, and increase available blood sugars for energy. These systems were useful when threats were physical and immediate. Modern stress often comes from worry, rumination, and online or relationship conflicts, which do not require physical action. When stress responses stay switched on for long periods, the body can experience ongoing strain rather than short-term preparation. This can make coping strategies that do not help more likely to persist.
