Stress is the trigger of various processes in our organism.
What exactly happens in our body when we are under stress?
When we face an event that our brain classifies as "dangerous", the whole organism is put on high alert.
The blood flow to the muscles increases, the senses are sharpened, the pain threshold is raised and we get goosebumps.
The central nervous system raises the pain threshold so that we can more easily endure a stressful event and possible injuries
Pupils dilate - this enables the reception of a greater number of photons, and therefore better vision, even in conditions of minimal illumination.
In the liver, sugar stored as a reserve substance - glycogen, turns into glucose, the basic source of energy that is immediately available.
The heart beats faster and stronger, which enables a greater flow of blood and oxygen to the muscles. Thanks to this, the muscles receive a higher level of glucose than under normal conditions.
The adrenal glands secrete a greater amount of the stress hormone - adrenaline, which enables faster reflexes and thinking and decision-making.
The blood flow to the intestines is reduced, and it is diverted to the brain and muscles, independent transporters.
