Do you hit a slump every afternoon? It can be a nuisance when you’re trying to work hard but having trouble keeping your eyelids open. This feeling is a common one, often referred to as “brain fog.” Brain fog is not just annoying sleepiness when you should be wide awake, it can also include other symptoms like memory issues, trouble concentrating, headaches, irritability, anxiety, insomnia, and trouble articulating thoughts. Brain fog can be caused by a variety of different things, some of which are preventable. The good news is that there are a variety of different ways to naturally help give your brain a boost and break through that mental fog.

Dietary Changes

It’s possible your brain fog could be caused by a food allergy or food sensitivity. What many don’t know is that it doesn’t have to lead to hives or throat swelling to be an allergic reaction. Some allergies, like gluten sensitivity, are mild enough that you may barely notice them. However, they can still cause a ripple effect in your body that leads to brain fog (plus digestive issues and other discomfort). Food sensitivity testing can help determine whether certain foods could be causing problems. If that’s the case, avoiding those foods may help clear up your brain fog, and potentially ease other health issues, too!
In that vein, even if you don’t have a food sensitivity or allergy, your diet can have a big impact on your mental clarity. Nutrient deficiencies can cause fatigue, particularly if the deficiency isn’t corrected. High-sugar foods, specifically refined carbohydrates and alcohol, can cause a spike in energy, followed by a crash. Swap carb-filled or sugary snacks for healthy alternatives like nuts, fresh fruits, and veggies to cut down on food-related brain fog.


You’ve likely heard statistics about just how much of the human body relies on (and is made up of) water. If your body isn’t getting enough water throughout the day, that can easily lead to brain fog — particularly if you are consistently under-hydrated. Give your brain and the rest of your body’s complex systems a boost by ensuring you drink water consistently throughout the day.

Caffeine and Alcohol

It may feel like you need to grab another cup of coffee to get through the afternoon, but too much caffeine can actually contribute to the effects of brain fog. Likewise, alcohol can also lead to ongoing brain fog. Both substances cause inflammation in the body, which is a major contributor to brain fog. Reducing your caffeine consumption may be hard initially, but minimizing or cutting out caffeine and alcohol can help get rid of brain fog over time.


It should come as no surprise that sleep issues can contribute to brain fog. Whether you’re not sleeping long enough or not sleeping well, ongoing sleep struggles can have negative effects on your brain and throughout your body. It might sound simplistic, but getting better sleep and sleeping longer can help eliminate brain fog. The caveat there is regarding other health issues that can affect your sleep. Sleep apnea, some medications, depression, and other concerns can affect how well you sleep, so the true relief for brain fog may hinge on helping your other health issue.

Health Concerns

Imbalances in the body and infections can contribute to brain fog. This includes things like hormone imbalances, low or high thyroid, insulin resistance, and fungal infections like candidiasis (yeast infection). These health concerns may not automatically seem connected, but they can impact the brain as well as body functions. Taking care of other health concerns can go a long way toward minimizing brain fog in the long run.

Natural Brain Fog Relief

There are a variety of natural ways to give your brain a boost and combat brain fog. In addition to the suggestions mentioned above, you can also try:

  • Probiotics
  • Sunshine and fresh air
  • Exercise
  • Vitamins and supplements
  • Meditation
