Causes of Dizziness and Shakiness From Coffee

Quick answer

• Dizziness and shakiness from coffee are often due to over-caffeination or individual sensitivity.
• Dehydration can exacerbate these symptoms, making caffeine effects more pronounced.
• Low blood sugar, either before or after coffee consumption, can contribute to feeling unwell.
• Underlying health conditions, though less common, can make you more sensitive to caffeine.
• Adjusting coffee intake, staying hydrated, and eating adequately can usually resolve these issues.
• If symptoms are severe or persistent, consult a healthcare professional.

What this problem usually is (and is not)

• This problem is usually a sign that your body is reacting strongly to caffeine, often due to too much intake.
• It is often related to individual tolerance, which can vary widely from person to person.
• It is commonly linked to other factors like hydration, food intake, and sleep quality.
• This is not typically a sign of a faulty coffee maker or brewing technique, unless you’re making extremely concentrated coffee.
• It is not a universal experience; many people consume coffee without these symptoms.
• It is not usually a medical emergency, but severe or prolonged symptoms warrant professional medical advice.

Likely causes (triage list)

• Over-caffeination: Consuming too much caffeine in a short period.
• Confirm by checking the volume and strength of your coffee and comparing it to your usual intake.
• Individual caffeine sensitivity: Some people are naturally more sensitive to caffeine’s effects.
• Confirm by observing if even small amounts of coffee consistently produce these symptoms.
• Dehydration: Not drinking enough water, especially alongside coffee, can intensify caffeine’s effects.
• Confirm by assessing your daily water intake and if your urine is dark.
• Low blood sugar (hypoglycemia): Drinking coffee on an empty stomach can sometimes worsen low blood sugar symptoms, or coffee’s effect on blood sugar can be a factor.
• Confirm by noting if symptoms appear when you haven’t eaten for a while or after a high-sugar meal followed by coffee.
• Lack of sleep: Being sleep-deprived can make your body more reactive to stimulants like caffeine.
• Confirm by evaluating your recent sleep patterns.
• Anxiety or stress: Caffeine can amplify feelings of anxiety, which might manifest as shakiness or dizziness.
• Confirm by considering your current stress levels and if you feel anxious before or after coffee.
• Medication interactions: Certain medications can alter how your body processes caffeine.
• Confirm by reviewing any current medications with a healthcare professional or pharmacist.
• Underlying health conditions: Conditions like heart issues or anxiety disorders can be exacerbated by caffeine.
• Confirm by consulting a doctor if symptoms are severe or you have other health concerns.

If you suspect low blood sugar might be contributing to your symptoms, a low blood sugar monitor can help you track your levels and understand the connection. This can be particularly useful if you often drink coffee on an empty stomach.

Fix it step-by-step (brew workflow)

1. Assess your current caffeine intake:

• What to do: Keep a log of how many ounces of coffee you drink and its estimated strength (e.g., espresso, drip, cold brew).
• What “good” looks like: Being aware of your total caffeine consumption from all sources.
• Common mistake: Underestimating caffeine content, especially in specialty drinks or larger mugs. Avoid this by using standard measurements.

2. Reduce coffee volume or strength:

• What to do: Try brewing a smaller cup, using fewer coffee grounds, or switching to a lighter roast.
• What “good” looks like: Enjoying coffee without adverse effects.
• Common mistake: Drastically cutting out coffee, which can lead to withdrawal symptoms. Avoid this by making gradual changes.

3. Stay well-hydrated throughout the day:

• What to do: Drink a full glass of water before and after your coffee, and continue to drink water regularly.
• What “good” looks like: Clear or pale yellow urine and feeling generally hydrated.
• Common mistake: Substituting coffee for water. Avoid this by consciously drinking plain water.

4. Eat something before or with your coffee:

• What to do: Have a balanced breakfast or snack that includes complex carbohydrates and protein.
• What “good” looks like: Feeling satiated and stable, without hunger pangs.
• Common mistake: Drinking coffee on an empty stomach. Avoid this by always pairing coffee with food.

5. Monitor your sleep patterns:

• What to do: Aim for 7-9 hours of quality sleep per night.
• What “good” looks like: Waking up refreshed and feeling energized throughout the day.
• Common mistake: Relying on coffee to compensate for chronic sleep deprivation. Avoid this by prioritizing sleep.

6. Switch to decaffeinated or lower-caffeine options:

• What to do: Experiment with decaf coffee, half-caf blends, or teas with less caffeine.
• What “good” looks like: Still enjoying the ritual and flavor of coffee without the jitters.
• Common mistake: Assuming decaf has no caffeine. It has trace amounts, but significantly less.

7. Brew coffee at the correct temperature:

• What to do: Ensure your coffee maker brews between 195°F and 205°F.
• What “good” looks like: A balanced extraction that doesn’t over-extract caffeine or other compounds.
• Common mistake: Brewing with water that’s too hot, which can lead to over-extraction and potentially more intense effects. Check your machine’s manual.

8. Use fresh, properly stored coffee beans:

• What to do: Buy freshly roasted beans and store them in an airtight container away from light and heat.
• What “good” looks like: A consistent, flavorful brew.
• Common mistake: Using stale beans, which can lead to inconsistent flavor and potentially a desire to brew stronger.

Prevent why does coffee make me dizzy and shaky next time

• Regular cleaning and descaling: Clean your coffee maker weekly and descale every 1-3 months to ensure consistent brew quality.
• Optimal water quality and storage: Use filtered water for brewing and store coffee beans in an airtight container away from light and heat.
• Correct coffee-to-water ratio and grind size: Aim for about 1-2 tablespoons of coffee per 6 ounces of water, and adjust grind size for optimal extraction.
• Proper filter use: Use the correct size and type of filter for your brewer, ensuring it’s properly seated.
• Basic safety checks: Always ensure your coffee maker is on a stable surface and unplugged when not in use or during cleaning.
• Listen to your body: Pay attention to how different amounts or types of coffee affect you.
• Don’t drink coffee on an empty stomach: Always pair your coffee with food.
• Stay hydrated: Drink plenty of water throughout the day, especially when consuming coffee.
• Manage stress and sleep: Address underlying stress and ensure you get adequate sleep to reduce sensitivity to caffeine.

Common mistakes (and what happens if you ignore them)

Decision rules (simple if/then)

• If you feel dizzy and shaky after your first cup of coffee, then try eating a balanced breakfast beforehand because an empty stomach can make you more sensitive.
• If you consistently feel shaky after coffee, then consider reducing your portion size or switching to a half-caf blend because you might be sensitive to caffeine.
• If you notice dizziness primarily when you haven’t had enough water, then increase your daily water intake because dehydration can amplify caffeine’s effects.
• If you’re drinking several cups of strong coffee throughout the day, then try spacing out your intake or switching some to decaf because you might be exceeding your caffeine tolerance.
• If you’re experiencing these symptoms alongside anxiety, then consider cutting back on caffeine and practicing relaxation techniques because caffeine can exacerbate anxiety.
• If you recently started a new medication and are now experiencing these symptoms, then consult your doctor or pharmacist because there might be a medication interaction.
• If your symptoms are severe, persistent, or accompanied by chest pain or shortness of breath, then seek immediate medical attention because it could indicate an underlying health issue.
• If you’re consistently tired despite drinking coffee, then focus on improving your sleep hygiene because caffeine cannot replace adequate rest and can make you more sensitive when sleep-deprived.
• If you use a very fine grind for drip coffee, then try a slightly coarser grind because over-extraction can lead to a more intense, sometimes harsher, brew.
• If your coffee tastes unusually bitter, then check your brew temperature and grind size because over-extraction can release more compounds, potentially intensifying effects.

FAQ

Q: Can certain types of coffee make me more dizzy and shaky?

A: Yes, generally, coffees with higher caffeine content like robusta beans, cold brew, or espresso-based drinks can have a stronger effect. Lighter roasts can also sometimes contain more caffeine than darker roasts by weight.

Q: Is it possible to develop a caffeine sensitivity over time?

A: While tolerance can build, factors like stress, lack of sleep, or changes in medication can make you more sensitive to caffeine’s effects, even if you previously tolerated it well.

Q: Does drinking coffee on an empty stomach really matter?

A: For many, yes. Drinking coffee on an empty stomach can sometimes lead to increased acid production and a quicker absorption of caffeine, potentially intensifying symptoms like jitters or stomach upset.

Q: How long does caffeine stay in your system?

A: The half-life of caffeine is typically around 5 hours, meaning it takes about 5 hours for half of the caffeine to be eliminated from your body. However, its effects can linger longer, varying by individual.

Q: Can adding sugar to my coffee contribute to dizziness?

A: Consuming a lot of sugar with your coffee can lead to a blood sugar spike followed by a crash, which might contribute to feelings of dizziness or shakiness, especially if you’re sensitive to blood sugar fluctuations.

Q: Should I switch to decaf if I experience these symptoms?

A: If reducing your caffeine intake, staying hydrated, and eating properly don’t alleviate your symptoms, switching to decaf or significantly reducing regular coffee consumption is a sensible next step.
