Your “Pick-Me-Up” Could Be Slowing You Down: What You Need to Know About Caffeine and Adrenal Fatigue
So often, when women are struggling with feeling exhausted and worn down, they turn to coffee or other caffeinated drinks to make it through the day. When they come to me for help and I gently suggest they cut back on caffeine their reaction exhibits just how important they feel caffeine is to their survival; some break down crying, while others emphatically say “No coffee? No way. I’m not doing that.” But when your adrenals aren’t working properly there are a lot of factors at play, and caffeine is definitely one of them. Cutting back on caffeine is one way to offer your adrenals the support they need to heal.
It’s certainly a cultural norm in the US to use caffeine to get us going in the morning. Just look at all the t-shirts, mugs and memes out there that tout the essential role of caffeine in our lives. Many of my patients say that their need for caffeine is priority one when they wake up; they even warn their families not to speak to them before they’ve had that first cup of coffee, tea, soda, or in a rather disturbing recent trend, energy drink of the day. So, I can understand the shocked reaction I see when I suggest avoiding caffeine.
But here’s the thing… I’m not actually suggesting that you shouldn’t have any caffeine. As with most things, moderation is key. But when coffee, or any other form of caffeine, is the only thing keeping you going, and you find yourself caught in cycle of caffeine-induced ups and downs, it’s time to take a closer look. Often, an adrenal imbalance that prevents restful sleep is hiding behind the caffeine crutch.
Caffeine won’t cause adrenal dysfunction all by itself, but your body changes with excessive intake of caffeine, putting stress on the adrenal glands. And if you choose an energy drink or coffee over a good night’s sleep or eating right, your adrenal health will suffer. Let’s examine the impact of caffeine on your body – more specifically, on your adrenals.
Understanding the Connection Between Caffeine and Adrenal Release
We all have a natural, physical response to stress. This “flight or fight” reaction is involuntary, and essential. It begins at the HPA (Hypothalamus, Pituitary, Adrenal) axis, and spurs the release of stress hormones – epinephrine (adrenaline), norepinephrine and cortisol – meant to jolt you into action when real danger is present. But caffeine masquerades as an emergency, spurring your adrenals into action when there’s no need for these stress hormones. And 100-200 mg of caffeine (for reference, one 8 oz. cup of Starbucks drip coffee contains approximately 155 mg of caffeine) is all it takes to set this response in motion.
Can you recall how you feel right after you drink and espresso? If you pay close attention, you’ll probably notice your heart begin beat faster, your muscles contract, and you’ll feel the instant energy from the sugar and free fatty acids your liver has released into your bloodstream. You may also notice feelings of anxiety or increased worry. But usually, when you’re having a caffeinated drink, there’s no actual emergency. Your body is ready to conquer a predator, even if you’re sitting enjoying social time with a friend.
That boost of energy works well when you need it – to react quickly while driving, for instance. The most critical function your adrenals have is to help you survive. But their secondary function, to provide balance in your hormones throughout your life, is important too – and even more so as you age.
The Complicated Relationship Between Caffeine and Adrenal Fatigue
Like I said before, I’m not saying you need to kick coffee to the curb. A cup or two per day probably won’t impact most women much, assuming they don’t have an unusual sensitivity to caffeine. But if you’re using caffeine to keep you going too often, or you’re drinking caffeinated beverages late in the day, you could be throwing your hormones out of whack. And if this goes on too long, adrenal fatigue could be the result. Let’s look closer at what caffeine is doing to your hormones.
Cortisol is integral to that flight or fight response we talked about, and impacts your ability to get restful sleep. It’s supposed to be high in the morning and lower at night. But caffeine changes the natural rhythm of cortisol, sometimes turning the cycle upside down. Additionally, when your cortisol is high too often, your body is in a constant hyper-alert state, which leaves you feeling exhausted. Often, when women feel exhausted, they turn to caffeine to help. It becomes a continuous loop – fatigue-coffee-energy-crash. You just can’t regain the energy you are seeking, no matter how much caffeine you consume.
To compound the issue, your adrenal glands aren’t just responsible for stress hormones; another critical job is to maintain appropriate levels of sex hormones. But when they’re constantly called upon for more cortisol, whether due to actual stress or caffeine-simulated stress, they just can’t keep up. In this way, caffeine may also be impacting your hormonal health.
If you happen to have insulin resistance, the relationship is even more complicated. Increased cortisol levels stimulate the release of glucose into your bloodstream, which in turn prompts the pancreas to boost insulin production that helps the glucose enter your cells and give you the increased energy needed to respond to the “threat.” The problem for women who already have insulin resistant cells is that, as studies have shown, caffeine exaggerates those responses. So, the caffeine you had in the morning can impact your insulin levels in a way that makes your blood sugar drop in the mid-afternoon. The fuzzy thinking and fatigue that result prompts you to reach for another cup of coffee to keep you going, and the cycle continues.
There are so many factors that change the effect that caffeine has on insulin sensitivity – gender; how healthy your body is; whether you’re eating or consuming caffeine on an empty stomach; and having caffeine, carbs and sugar (like a cup of coffee and a cinnamon bun) all at once. To further confuse things, the caffeine source seems to make a difference, too. For instance, research shows that tea seems to help reduce blood glucose. But even though there are plenty of questions, it’s clear that caffeine effects both insulin resistance and adrenal imbalance. Since it’s common for women to have both, and the two together complicate matters further, the caffeine connection is important to pay attention to when working to heal each.
Recovering from Caffeine Related Adrenal Fatigue: Finding the Right Balance
I know that it seems nearly impossible to some women to quit caffeine. Some women fall apart completely at the thought of giving it up for even a day or two for testing purposes. Caffeine is addictive, and not just in physical ways. Our culture places great social importance on bonding over coffee or tea. So, giving it up all at once might not be the best plan. The idea is to reduce stress, not exacerbate it! But I strongly recommend taking a step back – maybe say no to a third or fourth cup, and find healthy replacements like herbal tea and water. Adrenal healing is a long, slow process and you have to approach it in a way that works for you.
Remember, also, that I’m not saying you must go without caffeine forever. When you are healing, taking a break from certain food and drink is helpful in figuring out the roots of your symptoms. Nor am I suggesting you have to quit cold turkey. In fact, weaning yourself off caffeine slowly is important – otherwise, you’ll feel even more lousy, and quit before the healing process has really begun. Try cutting out one cup of coffee (or whatever caffeinated beverage has a hold on you) per day for a week at a time. For instance, if you typically drink five cups of coffee each day, start by having four the first week, then three the second week, until you’re down to one a day. This won’t feel too extreme, and can help you avoid headaches and other uncomfortable symptoms.
If you want to sustain healing long term, you’ll also need to examine your overall lifestyle habits, nutrition, and how you handle stress. This is much easier to do when you’re feeling great! And if you understand the impact of caffeine on your health, you’ll be far better equipped to define your relationship with caffeine on your own terms, instead of letting it define you!
