Biohack Brain Fog: 6 Ways to Boost Your Mental Clarity
That frustrating feeling of mental sluggishness, where your thoughts seem far away and focusing takes a lot of effort. It’s called brain fog, and you can clear it.
It's not a condition itself, but rather a cluster of symptoms that impacts your daily life and productivity. Brain fog happens when your body systems are not working properly. This is because of poor nutrition, inflammation, hormone imbalances, stress, and not getting enough sleep.
Fortunately, there are proactive steps you can start making to sharpen your mind and clear the mental haze.
1. Prioritize Quality Sleep
Sleep is key for our memory, cognitive function, and managing emotions. When you don’t get enough good sleep, you may experience brain fog, trouble focusing, or trouble remembering things.
How well you sleep matters just as much as how long you sleep. Getting 7 to 9 hours of uninterrupted sleep each night is what most adults need. So, try to go to bed and wake up around the same time every day to set your circadian rhythm.
If your sleep is constantly interrupted or restless, it will still leave you feeling foggy in the morning. Before going to bed, make sure you create a calming bedtime routine. Think about making your bedroom dark, quiet, and cool, and steer clear of caffeine and alcohol close to bedtime. Sleep apnea also messes with your brain. That’s why you should get it checked out.
2. Get Active and Moving
Staying active is important for both your body and brain. You don’t even have to hit the gym for long sessions. Do at least 150 minutes of moderate-intensity exercise or 75 minutes of vigorous exercise each week. Walk, run, or add some muscle-building activities at least twice a week to boost your overall health.
Exercise increases blood flow to your brain. It also encourages the growth of new brain cells and protects the brain's gray matter. Regular exercise helps reduce inflammation in your body, which might ease brain fog. It also releases endorphins that lift your mood and lower stress. This creates a better environment for clear thinking.
Moreover, staying active lowers your risk of cognitive decline and dementia as we age. Pairing physical activity with brain-stimulating tasks enhances these benefits even more. Even simple activities, like stretching or taking a gentle walk, help your brain process information faster.
3. Follow Stress Management Techniques
Managing stress is really important for our overall well-being and helps us think more clearly. For starters, meditation, mindfulness, deep breathing, and yoga help lower stress levels. Engaging in hobbies you enjoy is also a great way to unwind and take your mind off things.
And it’s interesting to note that mindfulness meditation doesn’t just feel good. It changes some aspects of our brain, making it stronger during stress. Chronic stress leads to hormone imbalances and inflammation, which may harm our thoughts and feelings. Using stress management techniques in our daily routine boosts our mental clarity and improves our overall health.
4. Make Dietary Changes to Lessen Brain Fog
Foods to Embrace
If you're looking to clear up that pesky brain fog, your diet makes a big difference. Eating a mix of fruits, vegetables, whole grains, and legumes gives your brain the nutrients it needs to work well. Lean proteins like fish, beans, and skinless chicken are also great to include.
Remember to include healthy fats in your diet, especially omega-3 fatty acids. You can find these in fatty fish like salmon and trout, as well as in nuts like walnuts and seeds like chia. These fats are fantastic for brain health. Berries are another powerhouse full of antioxidants that help boost brain function.
For cooking, olive oil is a smart choice since it's rich in healthy fats and antioxidants. Leafy greens, like spinach and kale, are packed with folate, which supports memory. Eating diets like the Mediterranean diet or the MIND diet is good for your brain. These diets focus on healthy foods. Spices such as turmeric and saffron also reduce anxiety and improve brain health because they contain antioxidants.
Foods to Limit or Avoid
On the flip side, there are definitely some foods you’ll want to limit or avoid to reduce brain fog. Think sugary drinks, refined carbs like white bread and pasta, and processed snacks. These cause blood sugar spikes and inflammation, harming your focus and memory.
Be cautious with trans fats found in fried foods—studies link them to memory issues. Moderating alcohol consumption is also key, as too much leads to confusion and memory problems. Watch for food sensitivities that might cause brain fog, like gluten, dairy, peanuts, and artificial sweeteners.
And if you can, reduce red meat and full-fat dairy since they're higher in saturated fats. We’re learning more about how gut health influences brain health, so it's beneficial to keep your gut in good shape. Making a few smart dietary choices will keep brain fog away.
5. Hydrate Your Body and Brain
Our brains can't hold water, so it's important to drink water regularly throughout the day to keep our brains working well. Drinking enough water during the day helps you avoid dehydration. Dehydration harms your focus, memory, and problem-solving skills. A good rule of thumb is to aim for about 8 ounces of fluid every hour during your first 10 waking hours.
Even losing 1 to 2% of body water makes it harder to pay attention and think clearly. Drinking enough water is important for our brains. It helps our neurotransmitters work well, provides energy for brain cells, and removes waste. Plus, not drinking enough affects our mood, leading to feelings of anxiety and fatigue.
However, drinking too much water is dangerous, but most people don’t need to worry about that. Everyone has different hydration needs depending on their activity level, the weather, and any medications they might be taking. It's important to listen to your body and know what it needs.
6. Take Some Brain-Boosting Supplements
Nutritional supplements can help reduce brain fog by filling nutrient gaps or improving brain health. Here are some important supplements to consider:
Omega-3 Fatty Acids: These are great for improving memory and learning. Omega-3 supplements also help with blood flow to the brain. An OmegaCheck blood test will check your fatty acid balance and see if you need supplements.
B Vitamins: They’re important for nerve function and energy. They also help produce neurotransmitters and build myelin, which is vital for cognitive health. If you're low on B vitamins, you might notice some cognitive decline.
Vitamin D: This vitamin boosts cognitive health, especially if you have a vitamin D deficiency. It may also help lift your mood, which clears up that brain fog.
Magnesium: This mineral is crucial for energy production and nerve function. If you don’t get enough, it contributes to brain fog. The L-threonate form of magnesium might even enhance your brain function.
Ashwagandha: This herb helps you feel less stressed and anxious. It also improves sleep and boosts your memory and attention.
Ginkgo Biloba: Some studies suggest it might help improve memory and speed of thought, especially in older adults or those with dementia.
Red Flags for Brain Fog: When to Get Help
If you've been feeling "foggy" in your head for several weeks, or it's getting worse than what you're used to, it might be a good idea to talk to a doctor. You should definitely reach out for medical advice if your brain fog starts suddenly or if it’s really affecting your daily life.
Keep an eye out for some of these signs:
Persistent brain fog (weeks or longer)
Sudden onset of brain fog
Severe brain fog is impacting daily activities
Brain fog accompanied by weakness, dizziness, slurred speech, balance issues, or vision changes
Changes in memory or thinking beyond typical aging
Brain fog despite lifestyle changes
Persistent trouble concentrating, chronic fatigue, frequent headaches, anxiety, depression, and lack of motivation
If you notice changes in your memory or thinking that seem worse than what’s expected with aging, definitely bring this up with your doctor. It’s also a good idea to mention any medications you’re taking, since some might contribute to your brain fog.
Your doctor can also order blood tests to check for health issues causing your brain fog, like vitamin deficiencies or thyroid problems. Mito Health offers a complete blood test that checks over 100 markers to start biohacking your brain health. This includes important measures like Omega-3 fatty acids, hsCRP, and fasting insulin, all related to brain fog.
