Hey Guys, how are you? I hope my blog posts are adding some value to you. As discussed in the last article, the impact of stress on our brain. We tried to highlight the biological implication of stress.

In this article, we will talk about the impact of stress on our career, job, study and so on...

We are now familiar with the problem that stress creates in our brain. Now we will discuss the outcome of the problem that stress creates in our brain.

Stress makes you stupid

A high level of cortisol in your brain will impair the decision making capability and thus can create a life-threatening situation for you. Every cognitive function is impacted negatively by the stress.

It has been found that continuous stress has seized the brain at the much needed times like jobs, interviews, exams etc.

A membrane named blood-brain is a semi-permeable filter which protects our brain from toxic substances like heavy metals, pathogens etc.

Stress reduces the density of this membrane and makes it leaky.

Having a leaky blood-brain barrier is associated with brain cancer, brain infection etc.

Dementia and Alzheimer's are two biggest threat to an individual because of stress or mental illness.

You will be shocked to know that Alzheimer is the 6th leading cause of death. One in three senior citizens will die of Alzheimer.

The worst part is Alzheimer is the most expensive disease in America.

Some researchers have suggested that stress in midlife can lead to Alzheimer.

Chronic stress and high level of cortisol are the leading cause of dementia in elderly people.

You need to keep a track of your mental health when you enter the middle age. Anxiety, a swing in mood, depression etc can hasten the progression of Alzheimer.

Stress causes the brain cell to commit suicide:

Stress can lead to premature aging of cells in your body and brain. Cortisol can kill the generation of new neurons in the hippocampus, that part of the brain that stores the memory.

Telomeres are protective endcaps on the chromosomes similar to the plastic cap on the shoelaces.

Every time a cell divides the telomeres gets shorter. Longer telomers to the production of new brain cells and vice versa.

As suggested by some researchers, telomeres are the best indicator of biological age and mental health diseases.


  • Stress hastens brain aging.
  • Stress depletes essential brain chemicals.
  • Stress halts production of new brain cells.
  • Stress enlarges the brain fear center.
Fortunately, changing your lifestyles and doing physical exercise or yoga can reverse the impact of stress on the brain.


How to help a chronically stressed Brain?

Take a diet full of anti-oxidant and try to add more fruits and green vegetables in your diet. It prevents free radicals from damaging brain cells.

Brain-boosting BDNF can be increased by indulging more in physical exercises and activities.

Start the meditation to keep the brain young and healthy. Meditation helps telomeres to stay longer in length.

Get plenty of sleep as it helps the brain to hasten the healing process.
