Mucosa, host defense, and the role of stress
In our quest to combat disease, modern medicine has developed an array of tools: from antibiotics and other antimicrobials, pharmaceuticals can provide a strong push-back against infection when necessary. Conversely, in cases where the immune system turns its fire against our own bodies (conditions collectively known as “autoimmunity”, for example rheumatoid arthritis, lupus, or certain inflammatory bowel diseases), we see the use of steroids, anti-inflammatories, and immunosuppressants. And while in either case these modern interventions can be life-saving, both circumvent our immune systems: antimicrobials purport to take over the job of fighting pathogens, while steroids and immunosuppressive drugs just turn the immune system off.
But our immunity is a sophisticated, subtle learning system that works best when it is fully engaged. In fact, we’re starting to discover that some of the dysregulation in immune function (hypersensitivities, asthma and allergies, for example) might be linked to an overly sheltered, microbe-free environment:
without exposure, without challenge, the immune system fails to learn the language needed to operate effectively in a world full of both microbes and allergens.
To herbalists, the use of drugs that fight infection or suppress the immune response as a first-line intervention seems akin to a parenting philosophy that either does a child’s work for her, or tells the child to be quiet and go to her room. Neither, in the long run, produces healthy, well-adjusted adults.
We strive instead to support our immune system’s own functional processes, much […]
As the year comes to a close, with some relief; and some anxiety about the state of our world in the future, we can turn to some simple routines to nourish ourselves. Sometimes it feels like time is moving too quickly, and the sense of longevity dwindles with the daily checklists and the demanding reality of our jobs, family lives, and social responsibilities. Time seems to speed up and the practice of personal time isn’t high on our lists. Living in a world that demands every ounce of your energy and attention requires radical self-care, particularly at the New Year and after the holidays. It builds the foundational blocks for the rest of the year and re-establishes a relationship with our deepest self and a genuine meaning of who we are and what we love.
Self-care not only builds our reserves and keeps our systems healthy and well, but it also de-clutters our mind and allows for more positive thinking to take place.
The beginning of a new year is the perfect time to turn inward and refocus on our needs. We will be better people for it. And our world needs strong and fiercely passionate people to be engaged and connected.
We all know what happens with elaborate New Year’s resolutions: they aren’t very lasting, and then we feel worse about letting them slip a week into the new year. Focus on small, tangible habits that will sustain the core of who you are and the changes you’d like to see. Everybody has different wants and needs— a nourishing ritual for […]
Our two adrenal glands are located on top of each kidney. From this perch, they not only have access to a rich blood supply, but are also close to the site of fluid and mineral balance in the body. This makes sense given their role: they participate in the stress response, of course, but are also involved in energy, libido, lean muscle growth, immune response, blood pressure, blood sugar, and water balance. So you can see how the hormones secreted by our adrenal glands have far-ranging effects: from the short-acting jolt of adrenaline to the longer-term influence of cortisol, which modulates metabolism in the liver, reduces our sensitivity to insulin, and suppresses inflammation (and immunity). We think of the adrenal glands as producing stress hormones, and this is true – but while we can perceive the effects of acute stress (heart racing, clammy hands, perhaps some anxiety), it is the more subtle ongoing hormonal activity of the adrenals that ends up having more profound effects on energy, metabolism, sleep, and mood. Unfortunately, this is hard to see until it’s gone: when our adrenal function begins to drop off, we notice fatigue, lack of motivation, metabolic slowdown, sleep disruptions, and more pain.
It is this last piece that usually serves as a good indicator that our adrenal function is sub-optimal: if we recover more slowly from vigorous exercise, feeling more fatigue – and crucially, more pain – after a big hike, or an extra-long jog, it can often mean that our reserve of adrenal hormones is flagging. This ability to recover and feel ready again is a key piece of the adrenal response, and, as it turns out, to healthy sleep patterns, too. […]
