What Causes Brain Fog?

what causes brain fog

Mental fog is not a comfortable thing to feel by any means. It can appear due to factors such as lack of sleep or high alcohol intake. However, it might also indicate more serious underlying health issues. Below are some of the most common causes of brain fog:

Hormonal Changes

Research shows[2] that hormones take part in many bodily processes, including cognition. Therefore, hormonal changes that happen during pregnancy, menopause, or when you have thyroid disorders[3] can cause forgetfulness, poor concentration, and cloudy thinking.


Stress leads to exhaustion and hypertension[4]. Consequently, it becomes harder to think, reason, and focus, all symptoms of mental fog.

Nutrient Imbalances

The brain requires vital nutrients such as vitamins B12 and D to perform optimally. When your body is deficient in these nutrients, processing information can become more challenging, leading to brain fog.

Lack of Sleep

As a rule of thumb, as an adult, you should try to get a minimum of 7 hours[5] of sleep each night. While achieving this in today’s fast-paced world may be challenging, poor sleeping habits can significantly affect your productivity due to poor concentration and cloudy thoughts.

Autoimmune Disorders, Pathogens,, and Age-Related Cognitive Impairment 

Autoimmune disorders[6] and pathogens are associated with a pro-inflammatory response, which impedes the brain’s normal functioning, leading to mental fatigue and mental fog. Additionally, age-related cognitive impairment[7] can trigger brain fog because as we age, the neurons in our brain decrease in speed, slowing down brain functions as a result.

How to Treat Brain Fog?

How to Treat Brain Fog?

How to get rid off brain fog? Mental fog leaves you feeling sluggish and unable to think clearly, which can be a major roadblock to your creativity, productivity, and overall happiness. Therefore, finding effective ways to bust these mental cobwebs is fundamental. Here are some of the best ways to alleviate brain fog.

Balanced Diet

Studies show that the human brain utilizes approximately 20% of the body’s calories, which implies that you must fuel your body with healthy foods for the brain to maintain its operations. Your brain requires beneficial nutrients like antioxidants[8] and omega-3 fatty acids to function optimally.

Eating a balanced diet every day can boost your cognitive performance and reduce the frequency of brain fog episodes. Some of the best foods to incorporate into your diet for brain health include herbs such as rosemary, berries, nuts and seeds, avocados, and oily fish. Also, don’t forget to treat your gut as well with the best smoothies for gut health!

Stay Active

Why not lace up those sneakers, grab a friend or two, and start exploring all the amazing ways you can stay fit and healthy? 30 minutes[9] of physical activity every day, whether through high-intensity training, running, swimming, yoga, or walking, can make a big difference in your health.

While being active will help you get in good shape, research shows that exercise tremendously impacts your cognitive function. Movements such as cardiovascular exercises enhance oxygen and nutrient delivery to the brain, stimulating neurogenesis[10] — the creation of new neurons in the brain. Consequently, this leads to better brain function, reducing brain fog. Research also shows that staying active can help lower the risk of neurodegenerative decline[11], ease depressive symptoms, and maintain hormonal balance, factors that cause brain fog.

Spend More Time Outdoors

Research shows that exposure to nature and green spaces, such as parks and woodlands, can improve cognitive function and alleviate mental fatigue. Additionally, being outdoors allows your body to absorb vitamin D from sunshine, which studies show supports optimal brain function. Therefore, while we are in a very fast-paced world, it’s best to allocate at least 20 minutes each day and bask in nature if you want to break away from mental fog.
