The Most Common Form of Hormone Imbalance
You've probably heard of the hormone cortisol being called the 'stress hormone'. While is is true that cortisol has a primary influence on stress it also supports a wide variety of other physiological roles. It is responsible for three major actions that keep you alive: raising blood sugar, increasing blood pressure and regulating inflammation.
Stress. It’s everywhere. The shoulder-tensing kind of stress that leaves you wired but tired, and taunts you to reach for that pick me up of sugar or coffee. Then comes the guilt because you know you aren't handling it appropriately. That's when we are stressed about our stress and that doesn't help! So, let’s take a look at the hormone cortisol as it relates to the stress response to get a clearer understanding of the biochemical state of the body when we experience hyperarousal (that is, the scientific term for what we might so very eloquently call “freaking out”) and explore how we can return the body to a state of balance and stability.
What is Cortisol?
In order to fully understand stress management and to discover a place of balance with out daily stress, it is important to understand cortisol’s dynamic influence on our everyday function. At the most basic level, cortisol is a hormone- a chemical substance that acts as a messenger to direct the activity of certain cells or organs in the body. You’ve probably heard of cortisol being called “the stress hormone,” but it is also responsible for three major mechanisms that help to keep the body in a state of balance, or homeostasis: raising blood sugar, increasing blood pressure and regulating inflammation. Through these mechanisms, cortisol essentially influences nearly all that we do, and is directly responsible for modulating:- digestion
- circulation
- sleep/wake patterns
- physical activity
- sexual response
- behavior and mood
Stress, The HPA Axis and Cortisol
Cortisol is released by the cortex (or outer layer) of your adrenal glands. It is naturally secreted in an ebb and flow rhythm that repeats daily. Ideally, cortisol is highest in the morning to help us to wake up in a productive, alert, and energetic manner. It then tapers throughout the day and evening, lowest at night when we are meant to be sleeping soundly, and at which point the soothing, anti-inflammatory hormone melatonin takes over.In addition to this daily cycle that helps us wake up in the morning and go to sleep at night, cortisol is released as part of the natural human stress response. In threatening situations, a surge of cortisol primes the body to react swiftly and appropriately. This very primal system is called the hypothalamic-pituitary-adrenal axis. Whenever a stressor is perceived, the hypothalamus (a gland in the brain) signals to the pituitary (a hormone gland in the brain) that something is up. The pituitary then sends a chemical alarm via the hormone ACTH, signaling to the adrenals (the glands atop your kidneys) to release a burst of cortisol and other hormones like adrenaline, preparing the body for “flight or fight” mode. This is where cortisol’s three primary mechanisms really come in handy: the surge increases glucose to the muscles so that one can fight or run, and blood pressure is raised to ensure a plentiful supply of fresh oxygen to the brain so that one is able to think clearly. Simultaneously, non-immediate functions such as digestion, sexual arousal and immune system reactions are temporarily suppressed, enabling energy to flow more steadily towards the vital functions that keep us alive. When the threat subsides, the alarm in the hypothalamus is shut off and the body is restored to a state of harmony, recovering and awaiting the next alert.
Adrenal Burnout
This method works great when there is an accident or medical emergency. Yet unfortunately the HPA Axis responds not only to those acute stressors, but also to those that are anticipated and perceived- our looming worries and fears. The HPA system is helpless in differentiating between psychosocial stressors like getting stuck in traffic or planning a dinner party, and physical threats such as being in a burning building. Therefore if we aren't careful, our daily life can have stressors everywhere and worry is rampant, so the HPA alarm is almost constantly stuck in the glowing red ON position. Cortisol levels soar in an unruly and destructive manner at bizarre times of the day and night, and suddenly small tasks such as packing a lunch or responding to an email, morph into treacherous evil threats that we feel like we just can’t handle.Over time, the body simply can’t compensate for this hormonal instability and we start to burn out. The adrenals simply cannot keep up with the burden of constantly being told to secrete cortisol, and our systems slowly falter and shut down under such demands. This phenomenon is often called adrenal fatigue, and is coupled with the experience of such troublesome conditions as heart disease, sleep problems, digestive issues, depression, memory impairment, excessive weight gain and worsening skin conditions.
Rebalancing Cortisol
As much as we might close our eyes tightly and try to resist and control it, stress is an inherent part of life. However, through adequate nourishment and care, we are able to put the body's biochemical systems back on track, shifting the way that we relate to stress so that it does not shatter our everyday experience and stifle our creative expression. Building a nutrient dense diet is essential to healing the adrenals, as is participating in healthy fitness that involves adequate amounts of rest and recovery. That's why practitioners at Healing Arts work with the biofeedback from your body to devise a detailed diet and lifestyle plan that works for you. Here are some of the things that we test for to help support and rebuild the adrenal glands.Fish Oil
Extensive research has shown that a high quality fish oil like cod liver oil, tuna oil or krill oil, rich in omega-3s and fat-soluble vitamins, can effectively lower cortisol levels that were increased by mental stress. Fish oil, especially when coupled with a source of vitamin K2, also provides the foundational nutrients that are beneficial in replenishing depleted hormonal stores and adrenal gland reserves.Deep Breathing
Due to our desk-sitting habits and stress-driven culture, many of us have actually altered the musculature of our natural posture and have become rapid, shallow, chest breathers. This breath habit compromises oxygen flow, weakens the abdominals, causes adrenal strain, compresses organs, creates lower back pain, and stimulates adrenaline-cortisol release. Learning how to breathe properly can neutralize this effect and turn off the HPA alarm.Magnesium
Numerous studies have found that the frequent release of adrenaline and cortisol involved in an unresolved stress response is strongly correlated with decreased magnesium. What’s worse? It all works in a vicious cycle: because lack of magnesium can cause anxiety, sleep disturbance and depression.B Vitamins
According to research, B vitamins, particularly Vitamin B5 (pantethine), work to reduce the hypersecretion of cortisol. Paradoxically, excess cortisol depletes B vitamins from the system, so people with high stress levels tend to be extremely deficient in these powerful vitamins. The B vitamins are most effective when taken together, thus eating foods that are high in all B vitamins such as liver, or taking high quality B vitamin supplements is crucial in restoring energy levels.
