Stress is a completely natural physical reaction. The stress reaction has developed as part of our evolution to enable us to react quickly by fleeing or fighting when we are faced with danger. We still react in this way to this day. If a situation is dangerous, exciting or challenging, it is viewed as “stressful”: the stress reaction is then triggered.
What happens when stress occurs in the body? Your pupils widen to improve your vision. Your pulse, blood pressure and respiratory rate increase to ensure optimum concentration and performance. Your initial rapid reactions are primarily driven by the hormones noradrenaline and adrenaline. As a result, the level of cortisol, also known as the stress hormone, increases and has a long-term effect.
Stress also has a residual positive effect nowadays if we need to be active for a short time, motivated, fully concentrated and totally focused on what we are doing. The stress reaction was originally only relevant for exceptional circumstances. However, it has become a permanent state nowadays and can have an impact on the health of the psyche and the body. This is also called “negative stress”.
