Brain Fog: What You Need to Know

We’ve all had days when we’re just not quite right. Maybe it’s because you slept too late and now you’re exhausted, or maybe it’s because you had too much coffee and couldn’t focus. But what if it doesn’t go away? What if your brain feels foggy all day, every day? Brain fog is a condition that affects millions of people—but it’s not recognized in conventional medicine.

There’s no code for it, so it’s not billable, so doctors don’t treat it. And that makes it hard to explain to people who haven’t experienced it before. But the good news is that brain fog isn’t something that needs to be ignored or put up with: there are things we can all do at home to feel more like ourselves again. We want to give people the tools they need to feel better faster!

What Is Brain Fog?

Brain fog is a very real thing, but it’s not an easy thing to explain. So let’s break it down: brain fog is not a concept—it’s actually a physical problem with the nerves in your brain that causes you to have hazy thoughts, difficulty recalling things, and even loss of endurance.

In other words, you can still do the things you’ve always been able to do, but they might take longer than before. Maybe you can’t quite recall an entire sentence as quickly as you used to be able to, or maybe it takes you a few more minutes than usual to finish up a project.

What Causes Brain Fog?

There are many potential causes of brain fog, but here are some of the most common ones:


You’re probably familiar with inflammation in your body, as it’s the body’s natural response to an injury or infection. When you get a cut or scrape, your body sends white blood cells and other chemicals to the area to help fight off infection and repair the damage.

But you might not realize that inflammation can also happen in your brain. And when it does, it can cause all kinds of problems, including brain fog.


It’s no secret that alcohol can cause many problems in your body. But you may not realize that it can also contribute to brain fog!

Alcohol’s effects on the brain are complex, but scientists have found that it can cause inflammation and interfere with communication between different areas of your brain.


Gluten also stimulates an immune response that causes inflammation throughout your body. When this happens, you may experience symptoms like headaches or migraines, memory loss, and mood changes—all signs of brain fog.


What’s the deal with dairy? It’s been a staple of our diets for so long that it seems impossible to imagine life without it. But is dairy actually good for us?

Dairy is a common culprit for brain fog, and not just because of lactose intolerance. Many people are allergic to milk proteins, which can trigger inflammation in the body. This inflammation can cause headaches and other symptoms of brain fog.

Blood Sugar

Blood sugar is your body’s fuel—it provides the energy you need to think, move, breathe, and live. When your blood sugar levels drop too low (as they do when you’re hungry), you feel tired and fuzzy-headed—and sometimes really irritable, which are symptoms of brain fog.


Stress is one of the biggest causes of brain fog. When stressed, your body releases hormones like cortisol and adrenaline, making it harder to think clearly and focus. Moreover, when stressed out, it’s easy to get caught up in your thoughts and lose track of what’s happening around you. You might start forgetting things or find that your thinking isn’t as clear as it normally is.


Exercise is essential to staying healthy and feeling good, but it can also cause brain fog if you’re not careful. When you exercise too much, your brain can get overwhelmed by the influx of oxygen and nutrients that your body pumps into it. This can cause your brain to shut down so it can deal with the influx.

On the other hand, if you lack exercise, your brain won’t get enough oxygen and nutrients to function properly. This can cause brain fog or make it worse.

Lack of Sleep

It’s no secret that getting a good night’s sleep can make you feel refreshed and ready to take on the world. But did you know that a lack of sleep can actually affect your brain?

Let’s face it: if you’re not sleeping enough, you will feel like your head is going wild. Unsurprisingly, people who don’t get enough sleep are more likely to experience brain fog.

But why does your brain feel so foggy when you don’t get enough sleep? The answer lies in how sleep affects your brain’s ability to consolidate memories and form new connections between neurons. When we don’t get enough sleep, our brains can’t do these critical processes as effectively—which directly impacts our mental clarity and ability to focus.

Allergies and Sensitivities

Allergies and sensitivities are major causes of brain fog. When you’re suffering from allergies or a sensitivity to something in your environment, your body releases histamines as part of an immune system response. Histamines can cause inflammation throughout your body—including the brain.

How To Manage Brain Fog

You can do a few things to help clear the cobwebs and get your brain firing on all cylinders again.

Get enough sleep

The first step to treating brain fog is to get enough sleep. Most people need around eight hours of sleep per night, but some people may need more or less. If you’re not getting enough sleep, your brain won’t be able to function properly, and you’ll start to feel foggy.

You can do a few things to ensure you’re getting enough sleep. First, try to go to bed and wake up at the same time each day. This will help your body get into a regular sleep cycle. Second, create a relaxing bedtime routine that will help you wind down before sleep. Finally, make sure your bedroom is dark, quiet, and cool. This will create the ideal environment for sleep.

Cut down on alcohol

Drinking too much alcohol can also lead to brain fog. Alcohol dehydrates your body and can disrupt sleep, making you feel dizzy and confused. If you’re drinking more than a couple of drinks per week, try cutting back to see if it makes a difference in your brain fog.

If you find that you’re still struggling with brain fog, it might be time to consider giving up alcohol altogether. There’s no need to feel like you must give up drinking completely, but moderation is key.

Exercise regularly

A good workout helps get the blood flowing and can jumpstart your brain. A walk around the block or a quick yoga session can do wonders for clearing out the fog. Moreover, regular exercise has been shown to improve cognitive function over time. So if you’re feeling sluggish, lace up your sneakers and get moving. Your brain will thank you for it.

Eat a healthy diet

One of the best ways to treat brain fog is to eat a healthy diet. This means eating plenty of fruits, vegetables, and whole grains. Eating a healthy diet can help improve your mood and energy levels, and it can also help improve your cognitive function. So if you’re feeling foggy, ensure you get enough nutrients by eating a healthy diet.

Get some fresh air

We all know how good it feels to get some fresh air, but did you know that it can also help clear your head and improve your concentration? That’s right, a little bit of time outdoors can do wonders for your mental state.

So, if you’re feeling foggy-headed and struggling to focus, take a break and walk outside. Breathe in some deep breaths of fresh air, and let nature work its magic. You’ll be surprised at how much better you feel after.

Manage your Stress

If you’re feeling foggy, it might be time to check in with your stress levels. When stressed, our bodies go into “fight or flight” mode, which can lead to a whole host of problems, including brain fog.

So, how can you manage your stress? Well, that depends on what’s causing it. If you’re feeling overwhelmed at work, try to take a break every few hours to clear your head. Maybe go for a walk or meditate for a few minutes.

It might be helpful to talk to a therapist if you’re dealing with personal stressors, like relationship problems or financial troubles. They can help you develop coping mechanisms and work through your problems in a healthy way.

Whatever the cause of your stress, there are ways to manage it. And when you do, you’ll likely find that your brain fog starts to lift.

Take mental breaks

We all know how important it is to take breaks when we’re working on something. But sometimes, when we’re feeling particularly foggy, it can be hard to actually step away from what we’re doing and give our brains a rest.

One way to ensure you’re taking enough mental breaks is to set a timer for yourself. Every 20 minutes or so, take a minute or two to just close your eyes and breathe deeply. You may also want to try some relaxation techniques, such as yoga or meditation. These can help clear your mind and give you some much-needed peace and quiet.

Talk to your doctor

If you’ve tried all these things and are still struggling with brain fog, it’s important to talk to your doctor. There could be an underlying medical condition causing your symptoms. Your doctor can help you figure out what’s going on and find the best treatment for you.

Bottom Line

All in all, you should remember a few things about brain fog. First, it’s important to understand that brain fog is not a medical condition. It’s a symptom of an underlying issue. Second, brain fog can be caused by various factors, including stress, lack of sleep, and certain medications. Lastly, there are ways to help relieve brain fog, such as getting enough sleep, managing stress, and avoiding alcohol.

If you’re experiencing brain fog, it’s important to talk to your doctor. They can help you determine the cause and develop a treatment plan. Get in touch with our team of experts today to learn more about how we can help you overcome brain fog.

Hi! I’m Dr. E, The NP with a PHD. Several years ago, my wife was diagnosed with an autoimmune disease and the only options given to us were heavy duty medications.
