Many of us acknowledge the intricate connection between our bodies and minds when it comes to stress, yet the average person may not be entirely certain about the underlying mechanisms.
Enter the hypophyseal-pituitary-adrenal-axis, or the HPA-axis. This intricate system interconnects various glands within the endocrine system (our internal hormonal messenger system), orchestrating hormonal balance to keep our bodies finely tuned and optimally functioning. However, chronic stress or traumatic events can throw the HPA-axis into disarray, causing a biochemical imbalance with far-reaching consequences.
While some stress is beneficial – like the exhilarating anticipation before a promotion – prolonged stress, such as that experienced by many during the pandemic, leads to elevated levels of cortisol, the stress hormone. These sustained high cortisol levels wreak havoc on the entire system, particularly impacting the hippocampus in the frontal lobe of each cerebral hemisphere. Primarily recognised for its role in memory and learning, the hippocampus falters under chronic stress, manifesting as brain fog, difficulty remembering recent events, and impaired cognitive function, which can greatly impact your ability to complete day to day tasks.
You may be asking, but how can I improve this? And how can I maintain any progress in a society with such relentless stress?
Well, a prudent place to start is to slow the pace.
Give yourself a mental reboot, so to speak, before beginning any journey towards improvement. Prioritise ample rest and become attuned to your circadian rhythm. This involves sticking to a consistent waking and sleeping routine, with a two-hour screen-free period before sleep to ensure that you are receiving quality sleep and, most importantly, the timely release of cortisol each morning.
Once you have your sleep schedule sorted, you should have a look at what you are putting into your body. Given the objective of mitigating stress, it's important to avoid stress-aggravating foods.
