Can Coffee Give You the Shakes? How to Stop Jitters
Ever wondered what’s happening inside your body when that pleasant coffee buzz turns into an uncontrollable shake? You reach for your favorite mug to boost your morning, but instead of focus, you get fidgety hands and a racing mind. This frustrating experience leaves many people asking: why does this happen, how much coffee is too much, and most importantly, how can I make it stop?
Yes, coffee can absolutely give you the shakes. This reaction, often called “coffee jitters,” happens because caffeine is a powerful central nervous system stimulant that triggers the release of adrenaline, the “fight or flight” hormone, leading to physical tremors and a feeling of restlessness.
This comprehensive guide breaks down the science behind why you can coffee give you the shakes and provides a clear, data-driven roadmap to understanding your limits. Leveraging extensive analysis of physiological responses to caffeine, we will explore the precise symptoms of overconsumption, unpack proven strategies to find immediate relief, and answer your most pressing questions. Get ready to take control of your coffee experience and enjoy your brew without the unwanted jitters.
Key Facts
- Official Safe Limit: The U.S. Food and Drug Administration (FDA) suggests up to 400 mg of caffeine per day is generally safe for most healthy adults.
- The Adrenaline Effect: Coffee can give you the shakes by stimulating the release of adrenaline (epinephrine), a hormone that increases heart rate and muscle tension, preparing the body for action.
- High Caffeine Content: A single grande-sized coffee drink from a popular chain can contain over 300 mg of caffeine, approaching the total recommended daily limit in one serving.
- Food as a Buffer: Consuming food rich in fiber, protein, or healthy fats before or with coffee can significantly slow the absorption of caffeine, which helps prevent the sudden spike that causes jitters.
- The Dehydration Factor: Caffeine acts as a diuretic, increasing urination and potentially leading to dehydration. Dehydration can worsen symptoms like shakiness and a racing heart.

Why Coffee Can Give You the Shakes: Understanding the Jitters
Coffee causes shakes by overstimulating the central nervous system. Caffeine blocks sleep-inducing chemicals while simultaneously releasing the “fight or flight” hormone, adrenaline, leading to physical tremors. Ever wondered what’s happening inside your body when that pleasant coffee buzz turns into an uncontrollable shake? The answer lies in a powerful chemical process that affects your brain and body, a process that is a well-established scientific principle.
Here is a step-by-step breakdown of how that simple cup of coffee can give you the shakes:
- Caffeine as a Potent Stimulant: At its core, caffeine—the primary active ingredient in coffee—is a psychoactive substance. Its main job is to act as a central nervous system stimulant. This is precisely why it’s so effective at increasing alertness and combating fatigue, but it’s also the root cause of the jitters.
- Blocking the Brakes (Adenosine): Inside your brain, caffeine’s primary target is a neurotransmitter called adenosine. A neurotransmitter is a chemical messenger, and adenosine’s message is simple: “it’s time to relax and feel sleepy.” Caffeine works by blocking the receptors for adenosine, effectively cutting the brake lines on your brain’s natural relaxation system. This is what keeps you feeling wide awake and alert.
- Hitting the Gas (Adrenaline): While it’s blocking your body’s relaxation signals, caffeine also encourages the release of adrenaline, also known as epinephrine. This is the body’s famous “fight or flight” hormone. A surge of adrenaline prepares your body for intense physical exertion by increasing your heart rate, sharpening your senses, and tensing your muscles for action.
- Nervous System Overdrive: When your central nervous system is hit with this one-two punch—no relaxation signals from adenosine and a flood of high-alert signals from adrenaline—it can go into overdrive. This overstimulation is what triggers the classic symptoms of coffee jitters. Your muscles become overly excitable, leading to the involuntary movements we know as shakiness or tremors.
How Much Caffeine Causes Jitters?
The FDA considers 400 mg of caffeine (2-3 cups) safe, but jitters depend on individual sensitivity and dosage. While there are official guidelines, the exact amount of caffeine that can give you the shakes is not a one-size-fits-all number. It varies dramatically based on your personal genetics, body weight, and how regularly you consume caffeine.
However, we can use authoritative data to establish a clear benchmark.
Quick Fact: The U.S. Food and Drug Administration (FDA) states that for healthy adults, a daily intake of up to 400 mg of caffeine is “not generally associated with dangerous, negative effects.” This is equivalent to about two to three 12-ounce cups of standard brewed coffee.
The key thing to remember is that this is a general safety guideline, not a guarantee you won’t feel jittery. For individuals with a high sensitivity to caffeine, symptoms can appear at much lower doses.
Furthermore, it’s incredibly easy to exceed this amount without realizing it. Many popular coffee shop drinks pack a significant punch. For instance, a single grande-sized coffee drink can contain over 300 mg of caffeine. Consuming one of these rapidly, especially on an empty stomach, can easily push you over the edge from pleasant alertness into a shaky, anxious state.
9 Telltale Symptoms of Coffee Jitters You Shouldn’t Ignore
Key symptoms of coffee jitters range from physical signs like shaky hands, a racing heart, and dizziness to mental effects like nervousness and anxiety. Do any of these feel familiar after your morning cup? You’re not alone. When you consume too much caffeine, your body sends clear signals that it’s been overstimulated. Recognizing these symptoms is the first step to managing your intake and preventing discomfort.
Here are the most common signs that you have the coffee jitters:
- Shaky Hands or Tremors: This is the hallmark symptom. It’s caused by an overstimulated nervous system, leading to increased muscle activity and a loss of fine motor coordination.
- Nervousness and Anxiety: You might feel a sense of unease, restlessness, or overwhelming worry that wasn’t there before your coffee. This is a direct result of the adrenaline surge.
- Racing or Abnormal Heartbeat: Caffeine directly stimulates your heart muscle, which can lead to palpitations or the feeling that your heart is beating too fast or irregularly.
- Dizziness or Lightheadedness: Overstimulation and changes in blood pressure can leave you feeling unsteady on your feet.
- Insomnia or Disrupted Sleep: Even if consumed early in the day, too much caffeine can interfere with your ability to fall asleep and stay asleep by continuing to block adenosine.
- Headache: While some use caffeine to treat headaches, too much of it can have the opposite effect, triggering a painful tension headache.
- Increased Blood Pressure: The stimulant effect of caffeine can cause a temporary but significant spike in your blood pressure.
- Dehydration: Caffeine is a diuretic, meaning it makes you urinate more frequently. If you’re not replenishing with water, this can lead to dehydration, which worsens jittery symptoms.
- Digestive Issues: An overstimulated system can also lead to an upset stomach, acid reflux, or even diarrhea for some individuals.
How to Stop Shaking After Drinking Coffee: 6 Actionable Steps for Immediate Relief
To stop coffee shakes immediately, stop all caffeine, hydrate with water, eat a balanced snack, take a light walk, and practice deep breathing exercises. If you’ve gone a little too far with your coffee intake and are currently experiencing the shakes, don’t panic. The feeling is temporary, and there are several effective, actionable steps you can take right now to calm your system and reduce the symptoms.
Here is your step-by-step guide to getting rid of the coffee jitters fast:
- Stop Caffeine Intake: This may seem obvious, but it’s the most critical first step. Put down the coffee, soda, or energy drink. Your body needs time to process the caffeine already in your system, and adding more will only prolong and intensify the symptoms.
- Drink Plenty of Water: Caffeine is a diuretic, which can lead to dehydration. Dehydration can make symptoms like a racing heart and dizziness feel even worse. Start sipping on water immediately to rehydrate your body and help it flush the caffeine through your system more efficiently.
- Eat Some Food: Consuming a snack or a small meal can help slow down the absorption of caffeine into your bloodstream. The key is to choose foods rich in fiber, protein, and healthy fats. This gives your digestive system something else to work on, acting as a buffer.
- Pro Tip: For the ‘Eat Food’ step, try a banana with peanut butter for a perfect mix of fiber, protein, and healthy fats. Whole-grain toast with avocado is another excellent choice.
- Take a Light Walk: If you’re feeling restless and full of nervous energy, some light physical activity can be very beneficial. A brisk walk or some gentle stretching can help your body metabolize the caffeine and burn off some of the excess adrenaline-fueled energy. Avoid intense exercise, as this could raise your heart rate even further.
- Practice Deep Breathing: When your nervous system is in overdrive, deep, slow breathing can activate your body’s natural relaxation response. Find a quiet place, close your eyes, and focus on inhaling slowly through your nose for four seconds, holding for four seconds, and exhaling slowly through your mouth for six seconds. Repeat this for several minutes to help calm your racing heart and mind.
- Rest and Wait It Out: Ultimately, the symptoms will only fully subside once your body has metabolized the caffeine. If possible, find a quiet, calm environment where you can rest and allow your body the time it needs to process everything.
To better manage your caffeine intake and avoid the shakes altogether, consider exploring high-quality caffeine-free alternatives that still provide a rich, satisfying experience.
FAQs About Coffee Shakes and Jitters
Navigating the world of coffee and its effects can bring up a lot of questions. Here are clear, direct answers to some of the most common concerns people have when they can coffee give you the shakes.
How long do caffeine tremors last?
Caffeine jitters can last for a few hours, depending on your personal metabolism and how much coffee you drank. The duration of the shakes is not fixed; it’s influenced by several factors. The most important are individual sensitivity, your personal metabolism (how quickly your body breaks down substances), and the total amount of caffeine consumed. For most people, the most intense feelings will subside within 3 to 5 hours as the body processes about half of the caffeine.
Are coffee jitters dangerous?
For most healthy adults, coffee jitters are uncomfortable but not dangerous. However, a persistent abnormal heartbeat warrants medical attention. While the feeling of anxiety and shakiness is unpleasant, it is typically a temporary sign of overstimulation. It’s your body’s way of telling you that you’ve had too much of a stimulant. That said, if you experience severe symptoms like chest pain or a very rapid and abnormal heartbeat that doesn’t go away, it’s always best to consult a doctor.
Why do I get shaky after drinking coffee on an empty stomach?
Drinking coffee on an empty stomach causes faster caffeine absorption, leading to more intense jitters. When there’s no food in your stomach, the caffeine from your coffee passes into your bloodstream much more rapidly. This causes a sudden, intense spike in its effects on your central nervous system. Think of food as a buffer that helps your body process the caffeine more gradually. This is precisely why eating a meal rich in fiber, protein, or fats is an effective strategy to prevent the shakes.
Should I stop drinking coffee if it makes me shaky?
Instead of quitting coffee, try reducing your intake, pairing it with food, and staying hydrated to prevent the shakes. You don’t necessarily have to give up coffee completely. For many, the solution lies in mindful consumption and simple adjustments. If coffee consistently gives you the shakes, consider these alternatives before quitting:
* Reduce your intake: Try a smaller cup, or switch to half-caff or decaf after your first cup of the day.
* Always drink with food: Never consume coffee on a completely empty stomach.
* Hydrate well: Drink a glass of water for every cup of coffee you consume.
Final Summary: Managing Coffee Jitters for a Better Brew
Ultimately, the answer to “can coffee give you the shakes” is a resounding yes, but it’s a manageable side effect, not an inevitable outcome. The jittery, anxious feeling is a direct result of caffeine’s power as a central nervous system stimulant, which triggers an adrenaline rush your body isn’t prepared for. By understanding this mechanism, recognizing the symptoms, and knowing your personal limits, you can effectively prevent and treat this common issue.
Take control of your coffee experience. By understanding why jitters happen and how to manage them, you can enjoy your favorite drink without the unwanted shakes.
Here are the most critical takeaways to remember:
- Understand the Cause: Jitters are a sign of an overstimulated nervous system caused by caffeine blocking relaxation signals and releasing adrenaline.
- Know the Symptoms: Be aware of the signs, from shaky hands and a racing heart to nervousness and anxiety, so you can act quickly.
- Use Immediate Relief Strategies: If you get the shakes, stop caffeine intake, hydrate with water, eat a balanced snack, and practice calming techniques like deep breathing.
- Prevent Future Jitters: The best strategy is prevention. Consume coffee in moderation, avoid it on an empty stomach, and always stay hydrated.
