Stress is not a buzzword in our society, but a perceived truth. According to a study, as many as 75% of all German professionals are sometimes or often under stress. But what exactly is stress, what causes trigger it and how can you recognise it?
What is stress?
The term stress was coined by the father of modern stress research, the Hungarian-Canadian physician Hans Selye. Selye defined stress as an ‘unspecific reaction of the body with which it reacts to its environment and to the demands placed on it’. Demands in themselves are not bad. They can spur us on to peak performance and help us grow. Consequently, a life completely free of stress and challenges is undesirable. We would miss out on the spice of life in the form of positive stress (eustress), the inner drive and the breeding ground for personal growth and a sense of achievement.
Chronic stress: when stress becomes a problem
If stress is the spice of life, why do so many people suffer noticeably from stress and its consequences? As with many things in life, when it comes to stress, it depends on the dose. While short-term stress can be inspiring (e.g. in exam situations), chronic stress means that the much-needed recovery phases are missing. When an external or internal stimulus is perceived as unpleasant or when you feel that you are unable to meet a particular challenge, then this is stress in its negative form (distress), which can have a negative impact on our physical and mental health. It is not for nothing that we say: ‘The stress is getting to me’, ‘This is maddening’ or ‘I'll have to digest that first’.
Stress models and types of stress
Not all stress is the same. Scientists distinguish between different types of stress, which have different effects on our body and mind:
Eustress vs. distress
- Eustress (positive stress) motivates and energises us. It helps us to overcome challenges and to surpass ourselves. Examples include an upcoming promotion, an exciting project or an important competition.
- Distress (negative stress), on the other hand, overwhelms us and can make us ill. It arises when we feel that we cannot cope with demands and have no coping strategies available.
Dimensions of stress
- Emotional stress: Arises from interpersonal conflicts, relationship issues or emotional overload.
- Mental stress: Results from cognitive strain such as information overload, complex decision-making situations or pressure to perform.
- Physical stress: Is triggered by physical factors such as lack of sleep, illness or intense physical exertion.
This differentiated view helps us to understand that stress is more than just an unpleasant burden – it can also be an important catalyst for growth and development.
Typical symptoms of chronic stress:
But how can unhealthy stress be recognised? The following symptoms can provide clues:
- Restlessness, tension
- Anxiety
- Irritability, anger
- Mood swings, bad moods
- Depression
- Concentration problems
- Fears
- Dissatisfaction
- Muscle tension, tension headaches
- Skin rashes
The stress response: a survival programme in the age of the performance-oriented society
Stress is not a new phenomenon. Since the beginning of time, our inborn protective mechanism has prepared us for survival in dangerous and stressful situations. However, while our ancestors were faced with life-or-death situations, today we are stressed by other things: financial worries, deadlines or fear of failure. The survival programme works the same way today as it did back then: when a stress factor (stressor) impacts the body, stress hormones are released and the entire organism is mobilised against the ‘impending danger’. While systems that can be neglected in the short term – such as libido, the immune system or digestion – are shut down, other systems are put into a state of readiness for flight or fight: breathing quickens, pulse and blood pressure rise, muscle tone and blood flow increase, while blood coagulates faster in preparation for possible injuries.
The biochemical stress process: what happens in the body
When we experience stress, our body undergoes a complex biochemical process that ensures our ability to survive:
The three phases of the stress response (Hans Selye's stress model)
1. Alarm phase:
- Stress hormones are released immediately (adrenaline and noradrenaline)
- Sympathetic nervous system is activated
- Heart rate and blood pressure increase
- Energy for flight or fight is provided
2. Resistance Phase:
- Persistent cortisol production
- Mobilisation of energy reserves
- The body's attempt to adapt to the stressful situation
- Increased alertness and performance
3. Exhaustion phase:
- If the stress continues, the body's resources are depleted
- Immune system is weakened
- Increased risk of mental and physical illness
These biochemical processes explain why chronic stress can be so dangerous to our health.
Does everyone feel stress the same way?
While the physiological stress reactions are the same for everyone, everyone perceives stress differently. While some are already saying, ‘I can't take any more,’ people with high stress resilience are holding the fort. These resilient individuals can withstand even severe stress and recover from its negative effects comparatively quickly.
Causes of stress: What triggers stress?
Even though each of us has an individual perception of stress, there are certain stressors that trigger the stress hormones of most of us. Typical stressors include:
- Conflicts at work or at home
- Deadlines and pressure to perform
- Multitasking
- Information overload and being constantly contactable
- The double burden of work and family
- Perfectionism
- Cases of illness or death in the family
- Divorce or separation
- Loss of job
- (Future) fears or worries
- Lack of work-life balance, little free time
- Overstimulation
- An unhealthy lifestyle
Health consequences of chronic stress
While short-term stress does not harm our body, chronic stress can have devastating effects:
Physical effects
- Cardiovascular diseases: increased risk of high blood pressure and heart attack
- Digestive disorders: gastrointestinal problems, irritable bowel syndrome
- Weakened immune system: increased susceptibility to infections
- Hormonal disorders: impaired metabolism
- Chronic pain: tension, headaches
Mental effects
- Development of depression
- Anxiety disorders
- Burnout syndrome
- Concentration and memory disorders
- Sleep disorders
Psychosocial effects
- Relationship problems
- Loss of performance at work
- Social isolation
- Decreased self-esteem
Early detection and professional support are crucial to breaking this vicious circle.
Conclusion: Stress is a complex phenomenon that affects each person differently. What is important is not to avoid stress completely, but to deal with it in the right way. With knowledge about stressors, warning signs and coping strategies, we can learn to manage stress and use its positive aspects while protecting ourselves from the negative effects.
Frequently asked questions about stress symptoms
The symptoms of stress are many and varied and can be both physical and psychological. Typical signs include restlessness, tension and nervousness, but also difficulty concentrating, irritability and mood swings. Physically, stress symptoms often manifest themselves in the form of tension, digestive problems, headaches, sleep disorders and a weakened immune system. Some people also suffer from heart palpitations, sweating or gastrointestinal complaints.
There are three main types of stress: emotional, mental and physical. Emotional stress arises from interpersonal conflicts and emotional challenges. Mental stress results from cognitive overload, complex tasks and information overload. Physical stress can be triggered by physical strain such as intense physical exertion, lack of sleep or illness. Each type of stress can affect the body and mind differently.
If you are under a lot of stress for a long time, your body can become exhausted. Chronic stress weakens your immune system, increases your risk of cardiovascular disease and can lead to mental health issues such as depression and burnout. In the long term, excessive stress can cause digestive disorders, hormonal imbalances, concentration difficulties and chronic pain. In addition, the risk of sleep disorders, weight problems and a reduced quality of life increases.
Effectively managing stress involves a range of strategies, including regular relaxation techniques, meditation and mindfulness exercises. Sport and exercise help to break down stress hormones and increase our sense of well-being. A balanced diet, sufficient sleep and setting priorities are also important. Maintaining social contacts, setting limits, improving time management and seeking professional help when needed are further effective methods of reducing stress.
Short-term stress, also known as eustress, can certainly be beneficial. It increases concentration and performance, improves motivation and can promote creativity and personal growth. Stress only becomes a problem when it becomes chronic and there are insufficient recovery periods. The balance between tension and relaxation is crucial.
Chronic stress has far-reaching effects on the body. It weakens the immune system, increases the risk of cardiovascular disease and can lead to digestive problems and muscle and joint complaints. Hormonal imbalances, accelerated aging processes and weight problems can also be consequences of long-term stress. It is therefore essential to recognise stress at an early stage and learn how to deal with it in order to stay healthy.
Professional help is advisable if stress symptoms persist for several weeks and significantly impair your quality of life. Warning signs include persistent exhaustion, increasing physical complaints, chronic sleep problems and social withdrawal. If everyday tasks become a burden or negative coping strategies such as alcohol consumption increase, professional support from a GP or psychotherapist is advisable.
