Stress dries the brain and makes you crazy! How to stop it?
Stress affects the brain much more than you think! Many may remember distraction, forgetfulness, anxiety, low mood, which often accompany stress, but did you know that it also dries the brain?
Hormones released during stress, affect not only the function of the brain, but also alter its structure.
The stress hormone cortisol causes death and prevents regeneration of hippocampal cells – the most important part of the brain responsible for learning, memory and emotion regulation. In addition, the hippocampus neutralizes the stress response in the body after a difficult situation over – quality, indispensable in the work and in their personal lives.
Chronic stress causes the degeneration of the medial prefrontal cortex.This negatively affects the decision-making function, working memory, and behavior control. Stress also affects the stem cells of the prefrontal cortex, which negatively affects the behavior of complex cognitive and socializing.As a result of all these processes in humans decreased memory and learning, developing a tendency to anxiety and depression.
But the trouble does not end there! Those same stress hormones increase the size and activity of the brain called the amygdala. In addition, it is responsible for the formation and storage of memories of different events, accompanied by a bright emotionality. They are stored in the form of long-term memories and depending on the type of emotion, or vice versa, we avoid such events forward again. Changes caused by cortisol, stained memories of fear, anxiety or aggression.
All of these disorders can affect our relationships with others, learning and decision-making, to achieve long-term goals. In addition, they make it difficult in the future resistance to stress, causing a vicious circle.
Fortunately, there is an antidote to all this! You’d be surprised, but this exercise. They improve the defense mechanisms against stress, as well as increase the size of the brain and improves cognitive function.
Physical activity stimulates the release of brain-derived neurotrophic factor – a substance that is responsible for the regeneration of a healthy brain and neutralizes stress. It strengthens the neurons and support them in a healthy condition, and also stimulates the formation of new nerve cells.The more we do, the more brain-derived neurotrophic factor stands out, and the brain regeneration processes are active, especially in the hippocampus.
Exercise also increase the release of growth hormones – growth hormone, which is responsible for development of cells throughout the body. Growth hormone slows the aging process and even increases the volume of the brain. Quick run for 30 seconds increases the growth hormone content of up to 6 times, and this effect lasts for 2 hours.
Do not worry, to achieve a positive effect on the necessary to spend long hours in the gym. Analysis of a number of studies have shown that 5-minute pause sports enough to relieve stress and improve mood. So if you had a free minute, go do something that increases your heart rate and uses the muscles work. Exercises help to keep the brain and do not go crazy!
