Caffeine, Anxiety, and Sleep: A Therapist’s Perspective on What Your Daily Routine Might Be Doing to Your Nervous System
As a licensed therapist, I work every day with individuals who are navigating anxiety, mood swings, and chronic sleep disturbances. And as a human being? I’ve been there too.
One of the most consistent patterns I see in both my clients’ lives and my own experience is the underestimated role that caffeine plays in how we feel — emotionally, mentally, and physically.
It’s socially acceptable (even encouraged) to rely on caffeine just to make it through the day. Coffee is a ritual. Tea is comfort. That midday energy drink or vitamin water might seem like a harmless boost. But for many people, caffeine is doing far more than keeping us awake — it’s contributing to the very symptoms we’re trying to manage.
The Impact of Caffeine on Anxiety, Mood, and Sleep
Caffeine is a stimulant, which means it ramps up activity in your central nervous system. For people prone to anxiety or high stress, this can increase symptoms like:
Racing thoughts
Heart palpitations
Restlessness or inability to sit still
Heightened startle response
Mood irritability
Digestive discomfort
It also disrupts sleep, even when consumed early in the day. Caffeine has a long half-life, meaning it stays in your system for hours — often longer than you realize. Even if you fall asleep, your sleep quality can be lighter, more fragmented, and less restorative. This leads to a frustrating cycle: feeling exhausted, reaching for more caffeine to cope, and continuing to interfere with your body’s natural ability to rest and reset.
My Personal Experience With Caffeine
Like many therapists and helping professionals, I’ve had seasons of deep exhaustion. There were times when that second (or third) cup of coffee felt essential — a small comfort in the middle of long days, emotional labor, and sleepless nights. But over time, I started noticing patterns: my anxiety was higher, my sleep was frequently disrupted, and I was living in a state of being “on” without actually feeling present or energized.
What helped was slowing down long enough to really notice what my body was telling me — and getting curious about how caffeine was affecting me beyond the short-term energy spike.
This isn’t to say I’ve quit caffeine completely — I haven’t. But I’ve shifted how I relate to it. I’ve learned to be intentional about when and why I consume it, and more importantly, how I care for my body and mind in the hours that follow.
Where Caffeine Hides (And Why That Matters)
One of the most overlooked parts of this conversation is where caffeine hides. Most people think they're only consuming caffeine if they’re drinking coffee or energy drinks. But caffeine shows up in:
Teas (especially black and green teas)
Chocolate
Flavored waters and vitamin drinks
Pre-workout powders and protein shakes
Over-the-counter headache medications
“Calming” drinks and supplements (yes, really — always check the label)
If you’re working on regulating your nervous system, improving your sleep, or reducing anxiety, it’s worth investigating not just how much caffeine you’re consuming, but where it’s coming from and when it’s showing up in your day.
Small Shifts, Big Results
This isn’t about giving up caffeine entirely — though for some, that might feel like the right step. For many of us, it’s about becoming more mindful:
How do you feel after that second cup?
What happens to your sleep when you have caffeine after 2 p.m.?
Are you drinking caffeine out of habit or because your body truly needs energy?
Are you relying on caffeine to mask the need for rest, nutrition, or emotional regulation?
The answers to these questions are not meant to shame or judge, but to help you develop a more informed and compassionate relationship with your own body.
How Therapy Can Help
In therapy, we often look at patterns — not just in relationships, but in behaviors and habits. If you’re struggling with anxiety, burnout, or sleep issues, your relationship with caffeine might be a meaningful piece of the puzzle. Therapy can provide the structure, tools, and accountability to explore those connections and make changes that support your overall well-being.
Whether you're ready to reduce your intake, switch to gentler alternatives, or simply get curious about what your body is asking for, the process doesn’t have to be overwhelming — and you don’t have to figure it out alone.
