Stress is the "modern" epidemic of the 21st century. The human body is not designed to be in a state of constant stress and remain he althy. But for how long? It is a part of our daily life and if we don't find a way to counteract it, it can cause great damage to he alth and especially to the brain. Check out 5 of them.

Creates an environment for free radicals

Stress causes the creation of free radicals, and the stress hormone cortisol creates an excess of a neurotransmitter called glutamate. While glutamate is a necessary and important brain chemical, its levels should not be elevated.

Glutamate creates free radicals – unbound oxygen molecules that attack brain cells the same way oxygen attacks metal, leading to rust.Or in short, stress destroys brain cells. It also indirectly contributes to other lifestyle habits that create more free radicals, such as insomnia, unhe althy eating, excessive alcohol use.

We forget about stress

Memory problems can be one of the first signs of stress that we usually notice in stressful situations. Emotions prevail and we hardly manage to focus on work, our household duties, sometimes days after the stressful situation has passed we cannot remember any details.

Stress creates a vicious cycle of fear and anxiety

Chronic stress affects an area of ​​the brain called the amygdala. This is the center of fear. When we are stressed, the level of activity and the number of neural connections in this part of the brain increases, causing a vicious cycle of intense fear and stress.

Inhibits the synthesis of new brain cells

Every day we lose brain cells, but we also have the opportunity to create new ones. Unfortunately, stress can affect the synthesis of new brain cells, increasing the risk of depression, obsessive-compulsive disorder, dementia, bipolar disorder, and Alzheimer's disease.

Stress makes us dumber

It has happened to everyone during an exam, a job interview, public appearances, business meetings that they could not gather their thoughts and performed poorly. This is due to stress. It's actually a survival mechanism.

If faced with a life and death situation, instinct and subconscious impulse override rational thinking and reasoning. Stress impairs memory and prevents us from making adequate decisions, remembering, being focused, thinking logically.
