Clear Brain Fog Instantly With These 12 Effective Strategies

Cut Down on Sugar

Oddly enough, poor gut health is one of the leading brain fog causes. "There is a ton of emerging research suggesting that the sugar and processed foods, which feed the bad bacteria in our gut, lead to inflammation not only in the body, but in the brain," explains Sarah Bridges, PhD, a Minnesota-based psychologist.

It's why you may often feel sleepy after a sugary treat or carb-heavy meal. That "crash" is not only physical but mental as well. In fact, about 95 percent of dopamine and serotonin (the feel-good neurotransmitters) are produced in your intestinal tract.

Eat Gut-Friendly Foods

While you may not want to skip your favorite goodies entirely, experts recommend incorporating more anti-inflammatory foods or brain-boosting drinks into your diet.

"Eating a variety of fruits and vegetables every day and taking prebiotics and probiotics can introduce healthy bacteria into the gut, which helps your body better produce those brain-boosting neurotransmitters," explains Dow. "You'll also want to make sure you're getting enough omega-3s, either from clean seafood or supplements, which can also remedy brain fog."

Try Intermittent Fasting

Intermittent fasting—limiting your eating window to window of time such as eight or 10 hours per day—may also improve brain function. "Intermittent fasting causes new brain cell growth, called neurogenesis. By giving your body a break from digesting, you're actually giving your brain a break as well," Bridges says.

Improve Your Sleep Habits

Sure, a bad night's sleep here and there isn't necessarily going to leave you sluggish the next day, but if your overall sleep patterns aren't optimal, your brain won't be at its best.

"Poor sleep habits can hit us in two ways, increasing our stress levels and disrupting the brain's opportunity to rest and recover," says Bridges. "This can come from having an inconsistent sleep schedule, not sleeping soundly, or waking up in the middle of the night—all of which can give you transitory brain fog."

Alleviate Your Stress

These days, our brains are inundated with information from the news, social media, and the constant influx of texts and emails flooding our smartphones. The result: Our brains are fatigued. "When you have too much of a cognitive load—meaning you're doing too many things at once, or have too much on your mind—it taxes our mental reserves," says Bridges. "It's too much for our brains."

According to experts, we have something called ultradian rhythms, which are cycles that play out during our waking hours. According to Bridges, research suggests that working in 90-minute intervals, and then taking a break to get water, take a short walk, or make a phone call, can help improve your brain power. "By minimizing those stretches of work time, you alleviate the stress on your brain."

Give Meditation a Go

Meditation can also help clear your head. Dow recommends meditating for 12 minutes every day (although even a few minutes will help). And absolutely, try to put the phone down for a few hours a day to prevent information overload.

Get a Walk In

We know that a good workout gets the blood and oxygen flowing through the body, so it makes sense that a lack of exercise would negatively impact our brain.

"Exercise increases blood flow and oxygen to the brain, helping it to perform at its peak," Dow explains. The good news is you don't always have to hop on a spin bike or get in some burpees to get moving (although those help!). Even a daily walk or other low-impact workout—an hour is best—can reset your brain.

Play Some Brain Games

According to Dow, when it comes to the brain, the phrase "use it or lose it" really rings true. So turn off the mind-numbing TV for an hour and play some solitaire, do a crossword, or play a brain game (preferably one with a memory element) instead. Even learning something new—as long as it's engaging and not stressful—can give your brain a much-needed tune-up.

Take a Nap

If you find yourself tired during the day, you're in luck—science says naps can have great effects on your brain. In one study, researchers found that adults who napped for 30 to 90 minutes every day performed better in memory challenges than those who didn't. Just be sure the naps aren't longer than 90 minutes because the same study found that longer snoozes may actually worsen symptoms of brain fog.

Spend More Time Outdoors

Have you ever noticed how at peace you feel looking at trees or in front of the ocean? Well, it's not a coincidence; nature is said to have positive effects on cognition. In one study, participants who spent more time in nature were more capable of problem-solving and creative thinking than those who spent less time in it.

Another study revealed that individuals who spent time in a garden exhibited synchronized brain waves, which led to a feeling of calmness. This is in contrast to those in a busy traffic island. Basically, it's safe to say that going out in nature will probably make you feel better.

Cut Down on Coffee and Alcohol

You've likely come across this advice before, but it bears repeating: Consuming excessive amounts of caffeine and alcohol may not be the best for your brain. Drinking too much coffee, or any kind of caffeine for that matter, may mess up your sleep schedule, and it's worth noting again that sleep is important in deterring brain fog.

Additionally, numerous studies indicate that heavy alcohol use can have long-term effects on the brain. In one study, middle-aged men who were considered "heavy drinkers" experienced more cases of rapid cognitive decline than men who drank less.

Socialize With Others

It turns out that hanging out with friends has many benefits, including brain-boosting ones. Research shows that adults who experienced social isolation were more likely to score lower on tests that used attention, memory, and decision-making skills. So, next time you're debating whether to hang out with friends, just remember, it's not just fun–it's good for your brain too!
