What are the symptoms of stress?
A stressor refers to any environmental demand exceeding the physiological regulatory capacity of an organism, especially under situations of unpredictability or uncontrollability.
In the last 2 decades, interest concerning the study of the mediating effects of different neurotransmitters on cognitive performance has increased. One possible factor mediating the negative effect of stress on cognitive performance is an imbalance in serotonin’s brain function (5-hydroxytryptamine). Increased serotonin activity in the brain seems to be a prerequisite for maintaining control over cognitive information processes and is involved in the learning process and memory.
The response to stress is an integral part of any adaptive biological system and its regulation is essential to face daily challenges.
How many types of stress are there?
According to different criteria about the individual's physical or mental state, there are different types of stress involving different maintenance and duration:
- Positive (Eustress): situation in which good physical health and mental well-being enable the body as a whole to acquire and develop its full potential. This brings motivation and energy to the individual.
- Negative (Distress): excessive stress because of a too great stimulus. This may lead to distress, anger, sadness. The harmony between body and mind is broken, what prevents us from responding properly to everyday situations.
Stress according to duration
- Acute stress: this is the most experienced. It’s caused by the demand imposed or that we impose on us and which can lead to situations of exhaustion. The signs of this type of stress are: muscle pain, negative emotions, stomach problems and increased activity of the nervous system (blood pressure, nausea, sweating, etc.). This type of stress can also occur at different times due to the demands of life today, so it can be called episodic acute stress as well.
- Chronic stress: this stress type occurs under extreme situations or situations repeated for a long time (for example wars), which make individuals who suffer from it to be under constant alertness and tension.
Signs of stress
The signs of stress in the body appear as a mix of sensations, feelings and physical weaknesses: rapid pulse, increased sweating, strong heartbeat, stomach discomfort, arms and leg muscles in tension, irregular and rapid breathing, teeth firmly clenched, closed jaws, inability to stay still and intense emotions. Alterations of the intestinal tract, weight changes and sleep disorders may also occur.
