Too Much Caffeine? Here’s How to Tell & What You Can Do About It

Many rely on caffeine to get them through the day – and for good reason. Caffeine can help improve energy and performance. It can fight fatigue. It can even have a positive impact on certain health conditions, like inflammation, obesity, migraines, and cardiovascular disease.

But having one too many cups can leave you feeling less than ideal. So, how can you tell when you've indulged in too much caffeine?

Common Symptoms of Too Much Caffeine

Everyone’s body metabolizes caffeine differently. This makes it difficult to know how much caffeine you should have on any given day. Once you cross that caffeine line, you might find yourself experiencing one or more of these common yet milder symptoms:

  • Jitteriness
  • Anxiety
  • Dehydration or increased thirst
  • Headaches or dizziness
  • Sodium or water retention
  • High blood pressure
  • Digestive issues, like diarrhea

Though rare, it’s possible to overdose on caffeine. This can result in more severe and concerning symptoms, like:

  • Increased heart rate, irregular heartbeat, or palpitations
  • Chest pain
  • Fever
  • Trouble breathing
  • Severe dehydration
  • Vomiting

If you experience one of these telltale signs shortly after having caffeine, you may have taken a bit too much. If necessary, be sure to seek medical attention.

What Do You Do When You’ve Had Too Much Caffeine?

If you’ve had too much caffeine, chances are you’ll notice it within the first 45 minutes after consuming it. When that happens, the effects can last for as long as 3-5 hours or, up to 10 hours. Yikes!

Learning what to look for when it comes to too much caffeine is an important first step. This will help you recognize when to cut it off.. But what should you do if you accidentally have too much? Here are three ways to help you manage some of the more mild symptoms:

  1. Drink water. You may have heard that caffeine, specifically coffee, can be a diuretic. It can also stimulate your bladder. This double whammy can lead to dehydration. So, to offset it, make sure to drink plenty of water and reach for foods that are high in water such as watermelon, cucumbers, and strawberries.
  2. Eat high-fiber foods. When you have food in your stomach, it can help slow the absorption of caffeine in your body which minimizes the secondary effects of caffeine in the bloodstream. Even better is to eat foods that are high in fiber such as lentils, seeds, nuts, and starchy vegetables. (Plus, fiber can also bulk up your stool and help to relieve diarrhea caused by the caffeine.It’s a win-win!)
  3. Get moving. The extra caffeine in your body can give you a nice energy boost but might leave you feeling a bit shaky. Try burning off the excess energy by doing a little exercise. Grab your yoga mat for a power yoga session, or throw on your shoes for a quick stroll!

Caffeine in moderation isn’t a bad thing, especially when it comes from green tea (one of our favorites!). Better to keep the black coffee to a minimum to avoid the jitters or upset stomach that can follow.

We’ve all been there – when you realize you’ve had one cup too many. Once it’s down the hatch, you can’t do much about it. However, there are a few super-simple ways you can minimize the unwanted side-effects.

Patient Testimonials

Dr Don Sharnowski is a doctor who is above and beyond all other doctors! Probably his most outstanding quality is that he LISTENS to what his patients say. He is willing to explain things to his patients in terms they can understand. Dr Don treats his patients with wisdom, understanding, gentleness, care, encouragement and he is willing to "go the extra mile" to give his patients the proper treatment they need. He does not treat patients like they were on an assembly line or like he is rushing them out the door. Dr Don has fixed many of the problems I had at my first visit, one of which I had endured for 3 years. Dr Don was able to fix that problem in 2 weeks when others had not. Dr Don has also helped me loose 40 lbs so far. My total recovery is still an ongoing process, but should be a cinch with Dr Don's expert help! Thank you, Dr Don! You are an awesome answer to prayers!

Dr Don Sharnowski is truly an amazing Doctor. He listens to his patients and treats in a very complete way. He is very knowledgeable because he never stops learning. He is a great communicator and will help you learn better ways to be healthy if you will actually do what he teaches.

Don (Dr Sharnowski) is truly one of a kind. He is warm, inviting and incredibly generous with his time, but also really knowledgeable about the body and everything within. You won't find crystal balls here. You'll find a super nice guy in sneakers who also sells farm fresh eggs at the counter. I went in expecting to get adjusted (and was scared, because I'd never seen a chiro before). Instead, what I experienced was someone who actually sat down and listened to my history, connected the dots between several ailments (instead of jumping to prescribe one drug apiece to treat each one), and explained things that no one had ever taken the time to do. I was there about my back specifically, but we talked about my whole health. Instead of just prescribing an anti inflammatory (which is what my other doc did), he explained why we get inflammation in our bodies, and how to help reduce it with what we eat. I've also been on thyroid medication for over 10 years, and he actually explained what the thyroid is, and what the drug I take is, and what it does. But not in a defensive or overly crunchy way. He just openly explained in a way that I could understand it. I highly recommend Don to anyone with a body who wants to feel better. His approach is approachably holistic. Just common sense, whole body-centered treatment.
