HOW STRESS AFFECT YOUR BRAIN

Are you having trouble sleeping, feeling irritated or grumpy, forgetting small details, and feeling overwhelmed and isolated? Don't be concerned. Everyone has been there. You're most likely simply stressed out. Stress isn't always negative.

It can be useful for a burst of increased energy and attention, such as while participating in a competitive activity or speaking in public. But when it is constant, as most of us encounter on a daily basis, it begins to affect your brain.

Chronic stress, such as excessive workload or having disputes at home, can change brain growth, shape, and function all the way down to the genetic level. The hypothalamus pituitary adrenal axis is a set of interactions between endocrine glands in the brain and on the kidney that influence your body's response to stress.

When your brain recognizes a stressful circumstance, your HPA axis immediately activates and produces cortisol, a hormone that primes your body for immediate action. However, prolonged exposure to high amounts of cortisol causes brain damage. Chronic stress, for example, raises the activity level and amount of neuronal connections in the amygdala, your brain's fear center. As cortisol levels rise, so do electrochemical impulses in the hippocampus, the area of the brain linked with learning, memory, and stress regulation.

The hippocampus also limits HPA axis activity, so as it deteriorates, so does your capacity to manage stress. But that's not all. Cortisol has the ability to cause your brain to decrease in size.When you consume too much of it, you lose synaptic connections between neurons and your prefrontal cortex shrinks, which is the area of your brain that governs functions like focus, decision-making, judgment, and social interaction. It also causes fewer new brain cells to be formed in the hippocampus.

This indicates that prolonged stress may make it more difficult to learn and retain things, as well as pave the way for more significant mental issues, such as depression and, eventually, Alzheimer's disease.The consequences of stress may even reach your brain's DNA. An investigation revealed that the amount of care a mother rat gives her newborn infant influences how the kid responds to stress later in life.

Because their brains generated more cortisol receptors, which cling to cortisol and suppress the stress response, the pups of loving mothers were less vulnerable to stress. The puppies of inattentive mothers had the reverse effect, becoming more sensitive to stress throughout their lives. These are referred to as epigenetic alterations because they affect which genes are expressed without directly altering the genetic code.These alterations can be reversed if the mothers are switched. However, there is a startling outcome.

One single mother rat's epigenetic alterations were handed down to several generations of rats after her. In other words, the consequences of these behaviors might be passed down through generations. But it's not all terrible news.There are several strategies to counteract the effects of cortisol on your stressed brain.

Exercising and meditating, which require deep breathing and being attentive and focused on your surroundings, are the most powerful weapons.Both of these activities reduce stress and enhance the growth of the hippocampus, which improves memory.So, don't be defeated by the stresses of everyday life. Take charge of your stress before it takes charge of you.
