Your Brain Under Stress

 Stress is a natural occurrence in everyday life. Stress may arise from school, family, friends, and even work. We may feel disorganized and forgetful under stress. The National Institute on Mental Health defines stress as “the brain’s response to any demand.”

It is no surprise that stress interferes with our minds and body negatively. It can contribute to physical symptoms such as stomach cramps, headaches, and chest pain. It can cause fluctuations in mood; sadness, anxiety, and various behavioral outbursts.

Chronic stress can have a huge impact on our brains. Chronic stress can lead to persistent inflammation in our bodies. The blood-brain barrier serves as protection for our brains. Under chronic stress, the barrier becomes leaky, causing inflammatory proteins to easily flow into the brain.

The hippocampus is a vital brain region for learning and memory. Studies have shown that chronic stress can affect brain systems linked to mental agility and motivation. Moreover, chronic stress also alters various neurotransmitters in the brain. Serotonin, for example, is responsible for mood regulation and wellbeing. Chronic stress lowers serotonin levels in the brain; this explains why selective serotonin reuptake inhibitors (SSRIs) are prescribed to people diagnosed with depression.

So what can we do if we are struggling with chronic stress? Exercise has shown significant benefits against chronic stress; reducing inflammation and increasing the production of new brain cells. It also improves our overall mood and physical health.

Most importantly, do not hesitate to reach out to close friends and family or a health professional. Talking to others, expressing your fears and doubts can help cope with stress tremendously.
