What Is Causing Your Brain Fog?

Brain fog is a common complaint for people of all ages. It’s that feeling that you can’t concentrate, despite putting in the effort. It’s that feeling where your thinking is cloudy, or where you sometimes have a difficult time remembering certain things, or memorizing new information. It’s that feeling of reading the same thing over and over and, despite trying your hardest, being unable to absorb the information.


Symptoms like brain fog are your body’s way of telling you that something isn’t quite right – whether that’s in the food we eat, the lifestyle habits we practice, or in our environment. It’s, therefore, so worth listening to our bodies when they are telling us something and do what we can to address the issue!


We should all be able to think clearly. With healthy aging, our cognitive function should stay intact. Unfortunately this isn’t the case, even for people in their 20s, so in this post we’ll be going over a few common causes of brain fog, and the steps that you can take to overcome it.


  1. Fatigue


Not getting enough sleep, or not getting enough good quality sleep is enough in itself to cause brain fog. We need 7-8 hours of sleep each night. There is no way around this; the body needs good sleep for good health and good brain function. Schedule sleep into your life. Reducing light exposure at night by winding down an hour before bed without exposure to screens (T.V.s, computers, smart phones, tablets) can improve your quality of sleep drastically by allowing good melatonin production to take place.


  1. Blood Sugar Imbalances.


We’ve talked about blood sugar imbalances and how they affect our energy levels before on the blog, but it’s definitely worth mentioning again! Our unlimited access to sweet foods and refined grain products has driven many of us onto a roller coaster ride of blood sugar instability. When we eat too many sweets or grains, and not enough healthy fats, protein, and fiber, we are likely to have blood sugar highs and lows. Blood sugar is our brains’ fuel, so when we don’t have enough of it we can wind up thinking unclearly. Eat a good breakfast that contains healthy fats and protein, and is low in sugar, in order to stay balanced throughout the day.


  1. Microbiome Imbalances.


An imbalance of healthy microorganisms in the body, particularly an overgrowth of Candida yeast, can cause a variety of symptoms throughout the body, including those that affect the brain. Candida yeasts can actually create low-level intoxication in the body, similar to the affects of alcohol! Eating fermented foods, taking a probiotic, and supporting the immune system can help establish more of a healthy balance, but working with a trained practitioner is often necessary in the case of Candida.



This is by no means a comprehensive list of root causes of brain fog. We all deserve to have a clear, focused mind so if you are experiencing brain fog it’s a good idea to talk to a trained practitioner who can help you get to the root cause of your symptoms!
