What Is Brain Fog? Causes, Symptoms, and Treatments

what is brain fog

Have you ever had one of those days where you just can’t think straight? You reread the same sentence over and over, forget what you’re doing halfway through doing it, can’t find the words during your meeting, and feel exhausted after doing the bare minimum. 

You might be experiencing brain fog. 

Although not an official diagnosis, brain fog is a common group of symptoms that affects mental clarity, concentration, and cognitive functioning. For most people, brain fog will pass after a day or a few hours, but for others, it is a symptom of a deeper illness or disorder. 

This article will go over the definition of brain fog, brain fog symptoms, causes of brain fog, and how best to treat it. If you feel like you’ve been walking in a haze, like your head is stuffed with cotton, read on to learn how to start feeling better. 

What Is Brain Fog?

Brain fog, or mental fog, is a common term used to describe a distinct set of symptoms. It is not a mental disorder or physical illness but is a common symptom of many disorders and illnesses. 

If you have brain fog, it’s probably a sign that something in your life is off. It could be as innocent as not sleeping enough or stress about an upcoming deadline, or it could be symptomatic of anxiety, depression, thyroid issues, and more. 

It’s not uncommon for brain fog to be the reason many people seek medical or mental health help. Brain fog makes it difficult to concentrate and get tasks done, which can be frustrating at best and detrimental at worst. 

Brain Fog Symptoms

Brain fog is often described as feeling mentally fuzzy—like there’s a fog in your brain that makes it difficult to find and formulate coherent, full thoughts. Here are some common symptoms of brain fog:

  • Difficulty concentrating or focusing on tasks
  • Memory problems, such as forgetfulness or trouble recalling information
  • Mental fatigue or feeling mentally drained, even after minimal mental exertion
  • Confusion or disorientation, feeling like your thoughts are clouded
  • Slower processing speed, which can make simple tasks feel more challenging
  • Difficulty finding the right words or expressing yourself verbally
  • Lack of mental clarity and sharpness, feeling like your mind is in a haze

If you're experiencing these symptoms, know that you're not alone. Seeking support, whether through therapy, lifestyle adjustments, or medical guidance, can help in navigating and overcoming brain fog. Let's work together to shed light on this and find ways to regain mental clarity for your brightest life.

What Causes Brain Fog?

If you’ve been experiencing brain fog, don’t worry. It is most likely caused by something mundane and easily fixed, like lack of sleep or your diet. Other times, medical intervention is needed. 

Here are some common culprits that can contribute to brain fog:

  • Lack of quality sleep or disrupted sleep patterns
  • Stress, anxiety, or overwhelming emotions (especially chronic stress)
  • Poor nutrition or dehydration
  • Side effects from certain medications
  • Hormonal changes, such as during menopause or thyroid imbalances
  • Environmental factors like exposure to toxins or pollutants
  • Chronic physical health conditions like fibromyalgia, chronic fatigue syndrome, or autoimmune diseases
  • Mental health issues such as depressionanxiety, or ADHD

Understanding the potential triggers of brain fog is an important step in managing and alleviating its effects. Once you understand the root cause, you can begin to work to undo it and regain your mental clarity.

How Do You Get Rid of Brain Fog?

Getting rid of brain fog is entirely dependent on treating the cause of brain fog. Sure, sleeping more is a good place to start, but if the root cause is a thyroid imbalance or anxiety, you’ll likely need to speak to a doctor or therapist. 

A good way to begin treating brain fog is by ruling out the simplest explanations and working your way up through more complicated causes. This ensures you won’t waste time and money on misdiagnosis, and you can ensure you’re receiving the right treatment. 

How to stop brain fog

Follow these steps when attempting to get rid of brain fog:

  1. Sleep more: Most people aren’t sleeping enough. Although common knowledge says everyone should aim for 8 hours of sleep, the real number can range between 7 to 10 depending on your body’s needs and the time of year (your body craves more sleep in the winter!). Women’s sleep needs will also fluctuate based on their period cycle. So, if you’re feeling brain-fogged, opt for an early bedtime!
  2. Take care of your physical health: Are you eating well, exercising regularly, and getting enough sunlight? (If you live in a cloudy, cold state, you could benefit from a sun lamp.) If you’re not, your mental clarity may be the first thing to go. Don’t neglect these parts of your mental health.
  3. Take breaks: Sometimes, brain fog is our body’s way of saying slow down. It’s not uncommon for new mothers or people with highly demanding jobs to experience brain fog. It is a common symptom of burnout. If you can, take breaks. If you can’t, lean on your support system or start a full self-care plan to prevent yourself from slipping into burnout. 
  4. Take a multivitamin: Moving up to more complex causes, some people may struggle with an iron or vitamin D deficiency. A multivitamin can help. 
  5. Talk to your doctor: Thyroid imbalances will affect more than 12% of people during their lifetime, and brain fog is a major symptom of it. Other issues could be contributing to your brain fog. Talk to your doctor about ruling them out. 
  6. Talk to a therapist: If it’s not a physical health issue, it could be a mental health issue. Anxiety, depression, ADHD, trauma, and more can all cause brain fog. If you’ve tried the other things on this list and are still struggling, talk to a mental health therapist. If you think you have anxiety or depression, try taking our free, online mental health assessment.
