How to Get Rid of Brain Fog

Aug 22nd 2023

Many people experience brain fog at some point in their lives. While not a medical condition, it can be described as forgetfulness or a lack of mental clarity. You might experience brain fog during bouts of stress or due to poor diet or dehydration. The good news is that relief is possible. Learn how to get rid of brain fog and stay healthy and focused.

What Is Brain Fog?

Brain fog, also known as mental or cognitive fog, is a common and temporary condition characterized by forgetfulness or lack of focus. People often describe brain fog as feeling mental cloudiness or fuzziness. You might also have difficulty accessing your thoughts or remembering information.

Common brain fog symptoms can include:

  • Clouding of consciousness
  • Trouble focusing
  • Memory loss
  • General fatigue or lethargy
  • Slow reaction times and information processing
  • Difficulty staying attentive
  • Trouble multitasking
  • Frequent loss of train of thought

Brain fog feels like fuzziness or lack of mental clarity. It can affect people of all ages and backgrounds. If you have brain fog, you might have trouble finding the right words during conversations, paying attention to your surroundings, or completing tasks throughout the day. This can be frustrating and impact daily activities, work, and personal life. Fortunately, staying hydrated, prioritizing sleep, and managing stress can help you regain clarity and start feeling better.

What Causes Brain Fog?

There's no definitive answer to what causes brain fog. One theory is that our body's immune system response leads to inflammation in the brain. As inflammation occurs, it can cause a temporary blockage in processing information. Stress, hormonal changes, dehydration, or poor diet can also result in brain fog.

Here are some potential causes of brain fog:

  • Hormonal changes: Fluctuations in hormones, such as during pregnancy or menopause, can impact your cognitive function and contribute to brain fog.
  • Stress and anxiety: High stress and anxiety levels can overwhelm the brain, leading to difficulty focusing and processing information, which contributes to brain fog.
  • Poor diet: People who eat a diet that lacks essential nutrients like vitamins B12, D, and omega-3 fatty acids can experience brain fog due to the effect on brain health and cognitive function.
  • Blood sugar levels: Blood sugar levels, whether too high or too low, can lead to cognitive disturbances, including difficulty concentrating, memory lapses, and mental cloudiness.
  • Chronic medical conditions: Certain chronic conditions, like autoimmune disease, fibromyalgia, or chronic fatigue syndrome, can be associated with brain fog as a symptom.
  • Dehydration: Inadequate water intake can lead to dehydration, impacting brain function and causing cognitive decline and brain fog.

Identifying the underlying causes of your brain fog can help you manage it correctly and improve your day-to-day life.

How to Get Rid of Brain Fog Fast

There are several ways you can manage brain fog symptoms and start feeling better. It's crucial that you see a health care provider if your brain fog persists with other cognitive symptoms.

Here are a few tips to reduce brain fog:

Take Vitamins

Low nutrient levels can be a cause of brain fog. For example, low vitamin D levels may negatively impact cognitive health and contribute to brain fog symptoms. One study found that postmenopausal women who took vitamin D every day for a year improved in learning and memory tests. Several other vitamins are also believed to help stop brain fog, including vitamin C, omega-3s, magnesium, B complex, and L-theanine.


Scientists believe various exercises can improve brain function and reduce symptoms like brain fog. For example, one study found that high-intensity exercise could improve cognitive function. To immediately address stressors that might lead to brain fog, try exercising at least 30 minutes per day, five days a week. Small changes in exercise habits can build up and help reduce stress while taking care of brain fog.

Eat a Healthy Diet

Sticking to a healthy, balanced diet positively affects the brain and body. Foods high in antioxidants, like blueberries, nuts, and oranges, can reduce oxidative stress in the body and help clear up brain fog.

Other nutritious foods include fish, which is high in omega-3 fatty acids and associated with lower rates of cognitive decline. In contrast, try to avoid caffeine and alcohol, which can lead to brain fog symptoms. A 2021 study found that chronic alcohol use increased inflammation in the brain and body.

Try Stress-Reducing Activities

Stress can be a significant trigger for brain fog. Try mindfulness exercises like meditation, yoga, and deep breathing to combat stress. Prioritize self-care by doing your favorite activities after a stressful workday, such as making art, listening to music, reading, or going on a walk. Immersing yourself in nature has also been linked to lower stress levels, improved attention, and many other cognitive benefits.

Prioritize Sleep

Poor sleeping habits can have an immense impact on the brain and body. Poor sleep can affect your ability to solve problems, make decisions, and regulate your emotions. Prioritize healthy sleep habits with a few lifestyle changes:

  • Go to bed around the same time each night.
  • Wind down at least one hour before bed by shutting off your electronics.
  • Avoid nicotine and caffeine before bed.
  • Keep your room dark, and try a sound machine to mask outside noises.

Take Mental Breaks

Taking breaks throughout the day is a great way to build up your mental capacity to handle stressors. Step away from your desk or computer and take 20 to 30 minutes to relax your mind without thinking about anything. Give yourself time to wind down even before you do other activities that require focus, like exercising, reading, or listening to music.

Stay Hydrated

The brain is around 85% water, so it's no surprise that drinking water can help keep us sharp. A 2021 study found that dehydration can affect memory and mood, revealing how important it is to build healthy hydration habits. Carry a water bottle throughout the day, including at work or school, and eat foods high in water, like fruits and vegetables.

A water filtration system is also a great way to build healthy habits. You might buy a water filtration system for the house that hooks to your existing hardware. These filters can improve the taste and quality of your drinking water, encouraging you to drink more and reap the benefits of healthful hydration.
