Stress seems to be ubiquitous, many people feel caught in the rat race, have to do countless things at the same time while the clock is ticking. But what is stress exactly?
The physiological stress response to threatening dangers is, in terms of evolutionary biology, a relict of olden times. Its typical signs such as increasing blood pressure, accelerated heartbeat, improved circulation of the muscles and the provision of energy are physical reactions to decision situations: Fight or flight from attackers or wild animals.
These reactions are triggered by the stress hormones adrenaline, norepinephrine and cortisol. They make the body ready to react in critical situations. The so-called eustress is therefore a completely natural physical reaction to a challenge.
