Why does coffee make me dizzy and light-headed? There are many possible reasons. Let’s explore some of them.
We’ve all been there. You drink a cup of coffee in the morning, and by noon you’re feeling dizzy and light-headed.
What gives?
Coffee is a diuretic (1), and this can cause you to become dizzy because it includes caffeine, which increases the pulse rate.
Those who have had previous heart problems or are over 60 may not be able to handle these changes in a heartbeat. The influence could make you feel faint or dizzy.
I’m caffeine sensitive. For me, even one cup of coffee can give me the jitters and make it hard to concentrate. Too much caffeine and I start feeling dizzy and light-headed.
If you’re like me, then you know how frustrating it can be to try to enjoy a cup of coffee when you know it’s going to make you feel this way.
In this article, we’ll explore some of the possible reasons why coffee might make you dizzy and light-headed. We’ll also look at some ways to prevent or reduce these symptoms.
How Caffeine Intake Affects the Body
To understand why caffeine may cause dizziness and lightheadedness, it’s helpful to know how caffeine affects the body.
Caffeine is a stimulant, which means it speeds up the central nervous system. It’s also a diuretic, which means it increases urine production.
Caffeine is absorbed into the bloodstream within minutes of being consumed.
It then travels to the brain, where it binds to receptors that normally would be occupied by adenosine.
Adenosine is a neurotransmitter that makes us feel sleepy. By binding to the receptors that normally would be occupied by adenosine, caffeine prevents feelings of fatigue and drowsiness.
Caffeine also increases the release of other neurotransmitters, like dopamine and norepinephrine. These neurotransmitters are associated with alertness and energy.
The effects of caffeine typically peak after about 30 to 60 minutes. The half-life of caffeine is about five hours, which means that it takes about five hours for the body to eliminate half of the caffeine consumed.
If you are sensitive to caffeine, you may start to feel the effects after just a few minutes. For others, it may take an hour or more.

Most of us metabolize caffeine pretty quickly and don’t experience any adverse effects. But for some people, even a small amount of caffeine can cause problems.
Coffee drinking on an empty stomach can irritate the lining of the stomach and cause indigestion, heartburn, and nausea.
Caffeine can also cause anxiety and jitters, particularly in people who are sensitive to it. And in large amounts, it can cause palpitations, irregular heartbeat, and high blood pressure.
If you are sensitive to caffeine, you may want to consider switching to decaf coffee or tea. Or, if you do drink caffeinated beverages, make sure to eat something with them to avoid irritating your stomach.
Symptoms of Caffeine Sensitivity
The symptoms of caffeine sensitivity can vary from person to person. Some people may only experience mild symptoms, while others may find that caffeine consumption has a more profound effect on their bodies.
Common symptoms of caffeine sensitivity include:
- Anxiety
- Jitters
- Heart palpitations
- Irregular heartbeat
- High blood pressure
- Dizziness
- Lightheadedness
- Nausea
- Headache
How to Get Rid of Dizziness After Drinking Coffee
There are a few things you can do to prevent or reduce the symptoms of caffeine sensitivity. Here are a few tips:
Drink Lots of Water
As I mentioned earlier, coffee can cause dehydration. If you’re feeling dizzy after drinking coffee, make sure to drink plenty of water. This will help rehydrate your body and reduce the symptoms of dehydration.
Eat Something Before Drinking Coffee
If you’re drinking coffee on an empty stomach, you may be more likely to experience symptoms of caffeine sensitivity. To avoid this, try to eat something before you drink coffee.
A light snack or meal will help to line your stomach and reduce the risk of irritation.
Choose Decaf Coffee
Decaf coffee makes a great alternative to regular coffee. It contains very little caffeine, so you’re less likely to experience symptoms of caffeine sensitivity.
Try switching to decaf coffee, but don’t drink too much of it. Just like regular coffee, decaf coffee can still contain small amounts of caffeine.
Stop Drinking Coffee
If you find that caffeine makes you feel dizzy and lightheaded, try reducing your intake.
Start by cutting back on caffeinated beverages like coffee, tea, and energy drinks. Don’t go cold turkey, as this can cause caffeine withdrawal symptoms.
Instead, slowly reduce your intake over a period of days or weeks. Once you’ve reached your desired level of intake, stick to it.
If you find that even a small amount of caffeine makes you feel dizzy and lightheaded, it may be best to avoid it altogether.
Final Thoughts
At Coffee Geek, we drink coffee regularly and enjoy its many benefits. However, we also understand that some people are sensitive to caffeine.
If you’re one of those people, the tips above should help you reduce the symptoms of caffeine sensitivity. If you find that you’re still experiencing symptoms, it may be best to avoid caffeine altogether.
Remember that, just like with any other stimulant, caffeine reduces blood flow to the brain. So ingesting coffee on an empty stomach can result in lightheadedness and dizziness.
Try to eat something before you drink coffee, or switch to decaf coffee if you’re sensitive to caffeine.
