- Evaluate your Diet. Eating the wrong foods can cause brain fog. Eating foods your body cannot digest can cause brain fog. The food doesn't necessarily have to be considered unhealthy to affect your cognitive function. Heatlhy foods that are bad for your body in particular can be culprits. Dairy allergies and gluten or other grain intolerances can affect your cognitive function. This can be tricky to do, but try to evaluate what you are eating and how it makes your body feel. If you suspect certain foods don't agree with you (trouble digesting, bloating, irregular bowel functions, mood swings, exhaustion, etc.), eliminate them for a week or two and see if you notice a change.
- Drink More Water. Your liver is the organ which rids your body of toxins. If you are dehydrated, your liver doesn't have the fuel it needs to adequately flush the toxins out. Drink more water. Otherwise, your liver doesn't function as well and these toxins remain in your body longer, wreaking all sorts of havoc.
- Get your Nutrients. Nutritional deficiencies can cause brain fog. A primary reason some people are deficient in certain nutrients it they eat foods their body cannot digest (and oftentimes they are completely unaware). Dairy, grain, and gluten intolerances can affect your intestines in such a way that they cannot properly absorb nutrients from the foods you eat. If your body isn't absorbing these nutrients, they aren't getting to your brain.
- Get Enough Sleep. Of course you need to be well rested in order for your brain to function properly. Evidence also suggests it is best to wake up at the same time each day, even on weekends.
- Stop Using Artificial Sweeteners. There is evidence to suggest that use of artificial sweeteners can cause brain fog. According to numerous sources, artificial sweeteners (including aspartame and flavor enhancers) are toxic to the brain, and can disrupt brain function.
