The body’s reaction to stress is called the “stress response”. Without this finely tuned process, we would not be able to get through a day. However, our modern-day high-tech, fast-paced lifestyles have elevated stress to epidemic levels. Our lives have become littered with psychological, physical, nutritional and environmental stressors, which in turn assault our body with chronic levels of stress hormones. Initially, there is some ebb and flow, but eventually, when stress becomes chronic, stress hormones are continually produced and released into the bloodstream.
Healthy Living How To friend Jaime Coffey Martinez, MS, RD and owner of , joins us today for a guest post tackling the topic of what to do about high cortisol levels.
If this describes some or all of your symptoms, you are likely experiencing the effects of stress and subsequent high cortisol levels.
Stress can result from psychological, physiological and/or physical reasons. When under stress, the body responds by increasing cortisol output from the adrenal glands. Normal cortisol levels are not detrimental. In fact, cortisol is both beneficial and protective in controlling blood pressure, blood sugar levels, inflammation as well as strengthening cardiac muscle. A should peak in the morning hours and then steadily decline through the day with the lowest levels at night. When the body experiences chronic stress, over time these levels increase above optimal range.
An acute rise in cortisol is not a bad thing, as it is the natural adrenal response to stress, like when you get a common cold, or experience an isolated stressful event or during exercise. However, when stress becomes unresolved or chronic, cortisol is continuously elevated and the body enters what is known as the adrenal resistance phase.
Chronically elevated cortisol levels are both inflammatory and catabolic and cause a myriad of disorders including: thyroid and metabolic dysfunction, cognitive decline, low serotonin levels resulting in depression, irritability, anxiety, carb cravings, immune suppression, altered glucose metabolism, elevated lipid levels, increased blood pressure, low melatonin levels resulting in altered sleep patterns, musculoskeletal issues resulting in difficulty recovering from exercise and possible subsequent injuries. Cortisol levels are also related to mental acuity and can factor into degenerative diseases such as dementia and Alzheimer’s.
DHEA, a precursor to sex hormones or more easily remembered as the “fountain of youth” hormone, also relates to adrenal function and unfortunately can have an inverse relationship to cortisol. Thus, if you have chronically elevated cortisol you may have proportionately low DHEA resulting in further metabolic disturbances including weight gain, poor immune function and hormonal imbalances.
Stress itself is unavoidable, yet you can take steps to manage your cortisol levels and limit metabolic disturbances. Whether your personal goals are weight reduction, improved health or sports performance, you hold the power to make changes to achieve your goals.
Cortisol causes gluconeogenesis, the production of sugar from non-carb sources. Thus, elevated cortisol increases your blood sugar levels. Eating a diet heavy in starchy carbohydrates and sugar further exacerbates elevated blood sugar leading to increased fat around the waist line as well as weight gain.
I recommend that those with elevated cortisol levels avoid sugar and limit starchy carbohydrates.
While exercise is recommended as one of the best forms of medicine, too much exercise at the wrong intensity level can be more inflammatory and further exacerbate cortisol levels in those that have already elevated values.
It is best to exercise when your cortisol is closest to normal range.
Sleep is the most important thing when it comes to reducing cortisol and restoring the adrenal glands. Work towards 7-8 hours of uninterrupted sleep between 10pm and 6am. Turn off all artificial light. That means put the iPad, Kindle, laptop, iPhone and any other electronic devices away. No television either.
Artificial light tricks the body into releasing more cortisol and thus suppresses melatonin making it difficult to sleep.
