Stress becoming stressed and it can also

Stress is not always bad. It can come in
handy when you need a rush of energy and focus, say, if you’re in a unique
situation like playing a sport and competing with others, or if you have to
give a speech. However, when it becomes persistent like the kind that most of
us face on a daily basis, it begins to alter your brain and its chemistry.

Chronic stress can affect brain size, its structure and how it functions. This occurs
by having too many arguments that lead to us becoming stressed and it can also occur
from being overworked.

Stress is initiated with the hypothalamus
pituitary adrenal axis. They are a set of connections between endocrine glands
in the brain. They control the body’s reaction to stress. When you are in a
stressful scenario, your HPA axis is activated and produces a hormone called
cortisol. Cortisol sets your body for immediate action. However, high levels of
it over prolonged periods can actually create issues for the brain, for
instance, chronic stress increases the level of activity and the number of
neural connections in the amygdala which is your brains fear centre. As levels
of cortisol increase, the electoral signals in your hippocampus, the part of
the brain associated with learning, memories, and stress control start to weaken
and lose connection with one and other. The hippocampus also prevents the
activity of the HPA axis, so when it weakens, your ability to control stress
also gets out of your control. The issue is that this is not the whole story. Based
on scientific research it has been proved that Cortisol can literally cause
your brain to shrink. Too much of it can lead to loss of synaptic connections
between neurons and the shrinking of your prefrontal cortex, the part of your
brain that controls behaviours such as concentration, decision making,
judgment, and social interaction.
