Stress - is the physiological response of the organism to external and internal stressors. It is the psychological, physiological and behavioral response of a person, an individual, who tries to adapt as much as possible to internal or external stimuli (stressors).
A stressor is a factor that causes stress or. disrupts the internal balance of the organism.
Positive stress (stress) - the body's response in a manageable situation, which gives a feeling of fulfillment and other positive emotions. Eustress is a correlation between life satisfaction and well-being.
Negative stress (distress) - a response to too strong stressors for the body. Distress can be short-lived, transient, or permanent. It manifests itself as a set of negative moods, frustrations, anxiety, sadness.
Chronic stress - Chronic stress is the brain's response to unpleasant events that recur over a long period of time, but these are not influenced or controlled by the individual. The causes are long-term unavoidable stressors and an increased propensity for a stress response.
Cortisol - Cortisol (also hydrocortisone or cortisol) is a corticosteroid hormone that is synthesized in the adrenal cortex. It is one of the so-called stress hormones, as it is secreted in the body during stressful situations. Its function is to raise blood pressure and blood sugar and immunosuppression - "silencing" suppressing the immune response to inflammation. Cortisol prepares the body for action, equips it with energy so that it can respond to a stressful situation appropriately.
Adrenaline - Adrenaline or epinephrine is a hormone and neurotransmitter secreted by the adrenal gland (released from the adrenal medulla) and mediates the conversion of glycogen to glucose. This process is called gluconeogenesis and takes place in the liver and to a lesser extent in the kidneys. As a result, higher blood glucose levels.
Blood pressure - is the pressure of blood in the veins. It is very important because it regulates the normal flow of substances through capillaries between the blood and the intercellular space. Therefore, there are many factors and physiological processes that keep it within normal limits.
Systolic blood pressure - is the pressure in the arteries during the heartbeat, when the heart contracts and squeezes blood into the blood vessels;; the cuff pressure is exactly the same as the pressure in the vein - the moment before the vein is still completely compressed together and there is no blood flow in it - normally 110–140 mmHg (15–19 kPa).
Diastolic blood pressure - is the pressure in the arteries between two beats, during the relaxation of the heart .; the cuff then no longer compresses the veins - normally between 60–90 mmHg (9.3–12 kPa
Neurotransmitters - Neurotransmitters or neurotransmitters is a group of heterogeneous biochemical substances that transmit information between neurons via synapses.
Neuron - Neurons or nerve cells are the main building blocks of the nervous system. Invertebrates, they are found in the brain, spinal cord, and nerves, and ganglia of the peripheral nervous system. Their main function is to trigger and translate nerve impulses.
Synapse - A synapse is a junction between two nerve cells separated by a small space.
GABA neurotransmitters - are inhibitory neurotransmitters in the central nervous system.
GABA receptors - are molecules on the cell membrane to which neurotransmitters specifically bind, substances introduced into the body (eg toxins, drugs) and consequently cause a biological response. Binding of the neurotransmitter GABA to the GABA A receptor - responsible for our well-being (when co-occupied, they give a feeling of relaxation, calmness, or if they are unoccupied they cause anxiety - anxiety, tremor, tension, nervousness, fear).
Anxiety - is anxiety, and it is also referred to as a state of nervous tension.
