We all want to feel vibrant and productive within our day, but brain fog symptoms like confusion, distractedness, fatigue, forgetfulness, and lack of clarity can impede our plans if we donât take action. Brain fog every now and then is normal â everyoneâs experienced a bad nightâs sleep or had too much going on â but if the manifestations of brain fog are all too present in your daily life and lead to other cognitive symptoms, itâs time to address some potential causes.
A foggy brain can be described as a lack of focus and cognitive clarity, or an inability to efficiently sort and recall information. Luckily, brain fog isnât in itself a lasting medical condition, but a sign that something else is going on. Ahead, read about some top causes of brain fog so you can clear up the cloudiness and shine brighter on a daily basis.
1. Diet and Gut Health
Nutrition provides us with our energy, and that goes for mental energy. When weâre reading, performing difficult mental tasks, or thinking critically, our bodies are burning more calories to keep up with the cognitive exertion, so itâs important that weâre feeding ourselves well in order to do our best thinking. In order to avoid one of the most common reasons for brain fog, consume a nutritious diet rich in natural ingredients that support brain health.
Reach for high-energy foods
As our body works to process extra sugar and carbohydrates, our blood sugar levels spike and then crash, and itâs during this postprandial crash that many will experience the dreaded âfood comaâ or â2 p.m. slump.â To avoid sluggishness or cognitive difficulties after you eat, try to keep track of foods that leave you with high energy or low energy and adjust your eating habits accordingly. Try adding these foods that help with brain fog and see if you notice a difference.
Address nutritional deficiencies
Itâs hard to keep up with all of the nutrients that our bodies need to have in balance. Aiming for adequate protein and around 30 different plants in your diet per week can be a good way to cover some nutritional bases. A diet high in whole foods and low in ultra-processed foods is the first step, but itâs important to get a regular blood work panel done in order to see where you could be coming up short. Whether you realize it or not, a vitamin deficiency may be the reason for your foggy brain and memory issues.
Consume essential fatty acidsÂ
Essential fatty acids are, no surprise, essential to brain health and nerve function, so itâs important to get healthy fats like Omega-3 and Omega-6 regularly since they canât be synthesized by your body. Some of the best brain foods include nuts and seeds like walnuts, almonds, chia, and flax, as well as extra virgin olive oil and avocados.
Pay attention to probioticsÂ
We share our gut with trillions of microorganisms â around 10x those present elsewhere in our body. When these gut flora are in balance, we can expect better overall health as a result. Specifically, thereâs a direct link between our gut microbiome and our brain health, so itâs a good idea to ensure that our internal cultures are being supported with probiotics found in fermented foods like kimchi and kombucha.
Supplement with nootropicsÂ
In addition to the foods we consume in our diets, there are also potent plants we can look to for herbal support. While we might not be serving up adaptogenic herbs in our home cooked meals, a nootropic blend like Brain DustÂŽ focus supplement can be a powerful way to support everyday cognitive function. In one teaspoon a day, this powder provides a potent blend of adaptogens and herbs:
- + Organic Lion's Mane is known to be neuroprotective*
- + Ginkgo supports speedy processing*
- + Rhodiola promotes alertness and concentration*
- + Organic Ashwagandha root promotes mental stamina and clarity*
- + Organic Astragalus known to promote healthy blood flow*
- + Organic Maca traditionally used to promote energy and memory function*
2. Lack of ExerciseÂ
When youâre feeling foggy, exercise could be the last thing you want to do. But the research is clear that making time for exercise will have positive impacts on your mental performance, including memory and focus. In one study of 144 people aged 19 to 93, a single 15-minute session of moderate exercise on a stationary bike improved cognitive performance across all ages. When brain fog hits, simple movements like jumping or skipping, or walking briskly around the block, could help you shake it off.
3. Lack of SleepÂ
No surprise here, but a lack of sleep can be the cause of mental sluggishness. Poor sleep quality and disrupted rest will affect how your brain works. For instance, one thing that happens when you sleep is that your brain is actually clearing away âwasteâ and releasing information you donât need to hold onto so that you can start fresh the next day. If this doesnât happen, itâs no wonder you might feel distracted, with disorganized thoughts during your waking hours. Try to get at least 8 hours of restful sleep every night in order to avoid brain fog and chronic fatigue.

4. DehydrationÂ
Feeling brain fog out of the blue? Try drinking some water and see if that helps. Our brain is sensitive to imbalanced hydration, so when you lose more than 2 percent of water in your body, you might notice symptoms like a shorter attention span, memory problems, and worsened decision-making skills. If you continue to be dehydrated, your brain cells can actually shrink in size, so itâs vital that you stay quenched.
5. Caffeine + AlcoholÂ
If youâre used to having several cups of coffee each day, itâs possible that the caffeine isnât giving you the same energy that it used to. If youâre brain fog despite keeping caffeinated, it could be a sign that itâs time to cut down or take a break. Letting your body readjust from the power of caffeine can be one step to reclaiming your energy when youâre faced with brain fog. Consider healthier alternatives to energy drinks and coffee next time you're looking for an energy boost.
It goes without saying, but alcohol and other mood-altering substances can also impair your mental clarity, both during use and later during a hangover. And remember that alcohol use significantly affects your sleep, so when itâs important to show up clear-headed, consider avoiding booze the night before.
6. StressÂ
Chronic stress, burnout, and overexertion are all culprits when it comes to brain fog. When your brain is already overworked, it becomes harder than usual to think critically and focus.
As a survival mechanism, the stress response can increase electrical activity in the fast-reaction part of your brain so you can deal with the âdangerâ at hand. But this can cloud your ability to rationalize, slow down, and focus, so that your thinking becomes foggy as a result. Stress also suppresses the hippocampus, or the memory and learning part of your brain, making it difficult to store and retrieve useful information.
7. Medical ConditionsÂ
Medical conditions, injury, and autoimmune disorders can also contribute to a feeling of brain fog. As such, brain fog can be symptomatic of an underlying issue or health condition. Any time you have a fever, you could experience temporary brain fog. If your brain fog becomes debilitating and goes beyond your standard mental fatigue, talk to your doctor, as it could be a sign of something more serious.
8. Life Cycle StagesÂ
Brain fog is often reported during pregnancy, PMS, and menopause. When our bodies are meeting our monthly cycle or transitioning to a new life cycle, these internal changes can take a temporary toll on our mental faculties. In fact, around 50-80 percent of pregnant women have reported short-term memory issues and other cognitive problems during pregnancy.
Sleep deprivation as the result of pregnancy or hot flashes can be one reason for brain fog, while a pregnant personâs placenta can also produce hormones that cause them to feel distracted or blurry.
9. MedicationsÂ
Modern medications can be much needed, but they also come with side effects. Meds like antihistamines, pain pills, bladder control drugs, and sedatives are all commonly associated with brain fog as a side effect. And if youâre on multiple prescription drugs at once, the chemicals can interact and exacerbate brain fog symptoms in unpredictable ways. If prescriptions could be the cause of your brain fog, talk to your doctor and holistic health care providers about a path forward.
10. Environmental ToxinsÂ
Toxins and endocrine disruptors in your house from mold, pet dandruff, and even harsh cleaning supplies can harm your health and cause brain fog. For instance, you might experience âchemical overloadâ and impaired neurobehavioral function after overexposure to harmful agents in household cleaning products from detergents to bleach.
11. Social Media UseÂ
Studies have shown that social media use can affect your attention capacity and memory and information processing. The constant influx of information predisposes us to distraction and makes us less able to focus on one task, shortening our attention span.
Research also suggests that social media use affects our transactive memory, hindering how we organize and store information. In addition to receiving information in the form of feeds and explore pages, weâre also receiving information about that information in the forms of likes, comments, and other engagements.
Consider setting app limits and downtime on your phone or computer to keep you accountable, and replace social media time with reading, which has been shown to improve memory and focus, or brain-boosting games like crossword puzzles.
