What Is Brain Fog?

Brain fog is not a medical disease; it is simply an umbrella term used to describe issues of cognitive function and how clearly the brain can think.

Brain fog can mean feeling:

tired mentally
slow in thought
difficult to concentrate
difficulty retrieving information from memory
confused
lack of focus

Brain fog makes it difficult to carry out daily activities, e.g.

studying
working
driving
reading
making decisions

Many people search for:

what causes brain fog and headaches
Why does my brain feel cloudy if I have a headache?
What are the symptoms of brain fog headaches?

What is a Brain Fog Headache?

A brain fog headache occurs when:

you feel mentally cloudy
at the same time, you have pain in your head

When these two combination experiences occur simultaneously, it can create the following symptoms:

pressure in the head
tightness around the forehead
slow in thought
difficult to concentrate/current events
reduced mental energy

Unlike a typical headache that only affects your head, brain fog headaches can also affect your brain, making them much more hard to withstand.

Why Does Brain Fog Go With a Headache?

Brain fog and headache are likely to be together because they are caused by the same thing.

So, where brain fog can be traced back to any number of causes, we usually hear that they are caused or related in some way to:

Brain blood flow
Brain chemical levels
Nerve signal pathways
Oxygen levels to the brain

When Something is not being done properly in or to the brain, we will notice how far off the "beaten path".

This will produce symptoms of:

Head pain
Confusion
Forgetful
Lose ability to concentrate

Research from Cleveland Clinic reports that brain fog is often connected to:

Stress
Not sleeping well
Hormonal imbalance
Not getting enough rest
Migraines

Most of the above diagnosis causes headaches at the same time.

Brain Fog / Headaches Symptoms

Symptoms can be anywhere from mild to severe.

Mild Mental Symptoms

Most of us have experienced these symptoms:

Can't concentrate
Can’t think clearly
Always forget
Confused
Can’t think of the right words
Can't learn new things

These symptoms can affect all areas of life.

Students
Workers
Professionals

Especially those who need to concentrate.

Not So Mild Physical Symptoms

If someone has Brain fog, they may have:

Pressure in their head
Dull headache
Squeezing sensation in their front of head
Light-sensitive eyes
Stiff neck
Always tired

Additionally, people who experience these symptoms may also experience:

Dizziness
Nausea
Sensitivity to light

These types of symptoms are common to someone with Brain fog due to migraines.

Brain Fog Headache - The Most Common Causes

Knowing the causes is the first step in how to get treated for this.

There are some causes that are important and have been established by research.

1. Stress (Main Cause)

Stress is one of the primary causes of having brain fog and headaches.

As stress increases:

your body begins producing cortisol
your muscles begin to tighten
your blood vessels will start to become constricted
you'll begin having headaches
your speed of thought will begin to slow down

If stress is chronic:

you'll frequently have headaches
have memory problems
mentally feel fatigued

According to the American Psychological Association's research, the brain's performance/function and concentration are both affected by having too much stress for too long.

2. Lack of Sleep

Having poor quality sleep is very closely linked to:

brain fog
headaches
decreased memory performance

The brain helps to:

dispose of toxins (waste products)
repair tissue
create new memories

If you do not get enough sleep, the result is:

becoming more likely to be plagued by headaches due to the brain having an accumulation of toxins
slower speed of thought

Most adults require between 7 to 9 hours of sleep a night.

If you receive less than that amount of sleep regularly, you may end up with brain fog.

3. Dehydration

Not drinking enough water can lead to:

headaches
dizziness
brain fog
poor concentration

Water helps:

bring oxygen to your brain
maintain blood flow throughout your body
support sending messages within your nervous system

Even being slightly dehydrated will adversely affect your ability to perform mentally.

4. Anxiety Disorders

Having anxiety is one of the factors that can affect your ability to concentrate.

Some common signs of anxiety include having:

racing thoughts
tight or tense muscles
headaches and/or head pain
mental fatigue and/or extreme tiredness

People with anxiety generally experience having:

brain fog
have problems remembering things
trouble concentrating.

5. Migraine Headaches

Migraines have a direct connection to brain fog.

A lot of people have

confusion,
slow thinking,
poor memory, and
difficulty with their concentration either before or after having a migraine attack.

Sometimes this is referred to as "migraine brain fog."

Brain Fog Headache From Anxiety

Many people are asking the question:

"Can anxiety cause brain fog and headache?"

Yes, it is a common occurrence.

When a person is dealing with anxiety?

The brain is always in alert mode

Stress hormones are high

Muscles stay contracted (especially the head and neck)

Blood flow changes in the brain

The result of these things is:

Tight headaches
Mental fatigue
Poor ability to concentrate
Brain fog

People suffering from anxiety tend to report:

Mental feeling of being "blocked"
Difficulty concentrating
Easily forgetting things
Experiencing head pressure or tension

According to the National Institute of Mental Health, anxiety will have an impact on both physical and cognitive function which would explain the frequent occurrence of brain fog and headaches.

Brain Fog Headache From Dehydration

Dehydration is a common reason for experiencing both brain fog and headaches and is often overlooked.

People are searching:

What causes brain fog/headache from dehydration?
Headache/brain fog from lack of water
Dizziness & fuzzy feeling/light-headed.

Your brain is approximately 75% water. Therefore, If you are not drinking enough water:

The blood flow to your brain will decrease.

The delivery of oxygen to your brain will decrease.

The result of these will be headaches.

Your ability to concentrate and not have any brain fog.

Diet and Brain Fog

Your brain needs certain nutrients to work well.

Not eating a healthy diet can result in:

Less energy
Slower brain function
More headache

Common food issues:

Too much sugar
Processed foods
Forgetting to eat
Not getting enough iron
Not getting enough of some vitamins (B12, D)

Having low blood sugar can lead to:

Sudden brain fog
Feeling weak
Headaches
Being irritable

According to Harvard Health Publishing, maintaining a healthy diet is very important for having a healthy brain and avoiding mental fatigue!

Brain Fog Following Illness

Many people say they feel: "Can't think clearly and have a headache because of being sick"

It is very common to feel this way after being sick with:

A virus
Flu
COVID-19
Chronic fatigue

This situation is sometimes called: "Post-viral brain fog"

Symptoms include:

Not being able to think clearly
Poor memory
Headache
Slow thought process

Your body is healing, and it may take a while for the brain to be back to full function.

Brain Fog From Hormonal Changes

Hormones influence how the brain functions.

When hormones change, it will impact:

Your mood
Your memory
Your energy level
How often you get headaches

Some examples of when this happens are:

During your menstrual cycle
During pregnancy
During menopause

When your thyroid is not working properly

If you have a hormone imbalance you can have:

Brain fog
Headaches
Fatigue
Mood swings

Medical websites such as Mayo Clinic state that a hormone imbalance can affect both mental clarity and headache patterns.

A common reason for brain fog headaches is lack of exercise.

When someone does not engage in physical activity, there is a decrease in the amount of blood flow and oxygen to their brain, as well as the mood-enhancing endorphins associated with exercise. As a result, when someone is sedentary, they may experience:

Decreased blood flow
Decreases in energy levels
Increased brain fog
Headaches

To alleviate symptoms caused by lack of exercise, there are some simple light exercises that can be done:

Walking
Stretching
Biking

Engaging in one or more of these exercises may help to eliminate or reduce the severity of symptoms at the same time.

Brain Fog Headache From Screen Time

excessive screen time contributes to brain fog headaches as well. Most of us have developed lifestyles where we spend a substantial amount of time on screens, which can lead to:

Eye strain
Headaches
Mental fatigue
Poor concentration

Particularly those individuals who use screens for long periods:

Cell phones
Computers
Tablet

Can potentially develop symptoms of "digital brain fog." Digital brain fog may be associated with:

Blurred thought processes,
Searching for focus,
Head pressure,
And eye fatigue.

Next, it is important to recognize that some people are more likely to experience brain fog headaches than others.

Who Is Most at Risk?

Those that fall into the high-risk categories for brain fog headaches include:

Students preparing for exams
Persons working in the office
Individuals with anxiety
People with poor sleeping habits
People with high levels of chronic stress
Individuals who do not eat healthily

If you fall into one or more of the high-risk categories above, you should take note of symptoms that develop early.

“Why do I continue to experience brain fog and headaches?”

Brain fog and headaches will persist because the underlying cause is never treated.

Some common causes of continued symptoms of brain fog and headaches include:

Chronic stress
Poor sleeping habits
Dehydration
Nutritional deficiency
Lack of exercise

Unless the reasons listed above are addressed, the symptoms of brain fog headaches will continue to persist.
