In this wonderful article, you will understand what brain fog is, its real symptoms, common reasons or causes, and 10 well-known natural methods to overcome it, and as a bonus, you will also get 2 real-life success stories.

What is Brain Fog?

Actually, brain fog is not a medical diagnosis, and it is a term which is used to explain a collection of cognitive signs or symptoms which interrupt your ability to think properly. It is actually like a mental fatigue or slowness which makes daily routines or tasks feel very hard and draining.

Anyone can get brain fog at any time, but brain fog is mostly seen in individuals who are following a busy and stressful lifestyle or people who are not getting quality sleep or in people who are having nutrient deficiencies.

Symptoms of Brain Fog

1) Feeling difficulty in concentrating and focusing on a particular thing.

2) Easily forgetting everything that happened very recently or things that you have just studied.

3) Feeling mentally slow and tired.

4) Uninterested or unenergetic to do things or tasks that you normally need to do.

5) Difficulty in processing the information.

6) Become confused and disoriented.

The above symptoms usually get worse when you have stress, improper sleep or poor nutrition.

Major Causes of Brain Fog

1) Bad Sleep

If you are a person who is not getting a deep and restorative sleep, then it will decrease your brain's capability to repair and stabilize new memories.

2) Inadequate Nutrition

If you have deficiencies in vitamin D, vitamin B12, iron and magnesium, then these deficiencies can slow your brain function.

3) Long-Term Stress and Anxiety Issues.

Cortisol is a hormone which is usually released at the time when you are stressed. This cortisol can badly or negatively influence your ability to remember things, pay attention and make proper decisions.

4) Hormonal Shifts

This happens mainly in females. They can have hormonal changes at the time of pregnancy or menopause, which can result in mental cloudiness.

Here is the complete guide on how to balance hormones naturally during menopause!

5) Inadequate Water Intake

Even if you are a person with mild dehydration, it can definitely affect your ability to properly concentrate and think properly.

6) Screen Fatigue

If you are exposed to the screens of phones, computers, or TVs for too much time every day or if you are a person who is getting frequent notifications from these devices in the form of messages, alerts, or updates, then these all can make your brain continuously active and overstimulated too, and eventually this will result in burnout.

7) Medical Issues

Some of the disease conditions, like thyroid disorders, high blood sugar, anemia, anxiety, or depression, can definitely disturb your brain's normal functioning or activity, and this can badly affect your focus, memory, and your ability to think clearly.

📲 Brain Fog: Due to Dopamine Imbalance and Excessive Digital Exposure

Dopamine is actually a chemical messenger that is present in your brain which has an important role in motivation, concentration, and reward processing.

In this current world, most of the people have mobile phones and are widely using social media and are regularly getting exposed to short videos and frequently getting notifications on their devices. Because of this, you are getting frequent spikes in your dopamin levels. But what is the problem with these repeated spikes in dopamine levels? Over time, due to these repeated highs (which means repeated feelings of excitement or pleasure), your brain becomes less sensitive and responsive to the dopamine.

Actually, what this mean is doing normal activities like learning, reading, or working can start to feel uninteresting or mentally draining, and because of this, you might have low motivation, difficulty focusing, and a short attention span, and all these factors lead to brain fog.

You can understand this condition as a type of "reward system fatigue", where your brain turns into an overstimulated state but is not very responsive.

Ways to Reset Your Brain

👉 Go for a "dopamine restart day" by staying away from social media, irrelevant content, and unnecessary exposure to device screens.

👉 Do real-world tasks or activities instead of screen-based activities such as reading, walking, or diary writing.

👉 Set specific time slots for doing focused work without any interruptions.

👉 Turn off the notifications on your devices which are not really important.

These types of small changes in your daily life can really help you to reset your brain's natural balanced state and to enhance mental clarity and focus.

🧠 Glymphatic System & Brain Fog

The glymphatic system is actually a special cleaning system that is present in your brain which functions when you are in a deep sleep state. This glymphatic system will help in removing all the waste products and also the toxins which build up in your brain throughout the whole day.

From the time when you wake up, you will be persistently thinking, working, or using electronic devices, and during all this time your brain will produce metabolic waste. If these metabolic wastes are not removed properly, then it can disrupt the normal functioning of your brain and will cause symptoms like brain fog, reduced attention, and difficulty processing the information.

But this glymphatic system will be very active only when you are in a state of deep sleep, mainly in the early part of the night ( e.g., If you sleep at 10 PM, then the early part will be approximately from 10 PM to 1 AM and the late part will be after that time, like 2-6 AM). So that, if you don't get a sufficient amount of quality sleep or if your sleep cycle is disrupted, the cleaning process by the glymphatic system becomes ineffective, and because of this, the toxins will get accumulated in your brain, and that will lead to brain fog with time.

🔔 Simple Methods to Support this Cleaning System

1) Go to sleep before 11 PM so that your brain can detox effectively at the early deep sleep state.

2) Try to maintain a stable and regular sleep schedule each and every day.

3) Avoid eating heavy foods and avoid screen time before your sleep time.

4) The glymphatic system functions well when you lie on your side as compared to when you sleep on your back or stomach. So, sleeping in your side position can enhance this waste- clearing mechanism.

⚡ Importance of Mitochondrial Dysfunction in Brain Fog

Your brain needs lots of energy to do even simple and small functions such as thinking of something, memorising something, and making decisions. And do you know this energy is made by very small structures which are present inside your cells called mitochondia?

So, if your mitochondria is not working effectively, then your brain will not get a sufficient amount of energy to function at its maximum efficiency level, and this particular condition is called mitochondrial dysfunction, and it might result in symptoms like mental exhaustion, reduced thinking speed, and also reduced focus.

Simply, we can say that in some people the brain fog is not only just due to their stressful situation or low-quality sleep; it can also be because their brain is not getting sufficient energy at the cellular level.

🔔 What factors badly affect the function of your mitochondria?

• Eating foods containing high sugar and consumption of packaged foods
• Experiencing long-term stress
• Following a sedentary lifestyle with low physical activity

🔔 How can you naturally increase the brain energy?

✅ Do exercises or movements like stair climbing or jumping jacks for a short period of time, like 1-5 minutes, a few times throughout the day to boost the energy production.

✅ Regularly get exposed to morning sunlight to support your physiological cellular rhythms.

✅ Consume highly nutritious food items like green leafy vegetables, seeds, nuts and healthy dietary fats.

✅ Try to eat your meals, like breakfast, lunch, and dinner, at fixed timings every day, because this can help in keeping you steady.

So, through boosting the energy production in your cell, you can strongly increase your mental sharpness, concentration, and overall brain performance.

10 Science-Backed Methods to Overcome Brain Fog Naturally

Now let's forget the usual advice like "sleep more and get proper hydration". At first let me tell you, the strategies that I'm giving you here are less-known strategies, but of course the science supported strategies. All our methods work by focusing on and fixing the real causes of brain fog, and these methods target the root biological and lifestyle patterns resulting in brain fog.

1) Try TRE (Time-Restricted Eating)

In this method, what you have to do is, other than eating small snacks all day or all the time, you can try to consume all your meals only during a fixed 8 to 10 hour period every day (for example, from 10 AM to 6 PM).

Research shows that TRE has the capacity to improve your body's circadian rhythms, make your cells' energy centres function in a better way, and also reduce inflammation in the brain. All these benefits of TRE can elevate your memory, concentration and brain function.

Extra Tip: Stop consuming foods 3 hours before sleeping or bedtime, which will help your brain's glymphatic system to detox efficiently and effectively during sleep.

2) Add Adaptogens Into Your Daily Diet

Some of the natural adaptogens are ashwagandha, rhodiola rosea, and lion's mane mushroom. These adaptogens can really help your body to handle your stress better and also will boost neuroplasticity. 

Adaptogens can support your brain health, decrease mental fatigue, and enhance your focus, memory and thinking capability.

3) Activate Your Vagus Nerve

The Vagus nerve is an important nerve which connects your brain and gut. So if you stimulate your vagus nerve, then it can definitely enhance your memory, focus and the way you handle your stress.

So what do you have to do to activate your vagus nerve?

1) You can perform gargling with water every morning.

2) You can try splashing cold water on your face.

3) Try to do humming or chanting for five minutes every day.

Through these ultra simple techniques, you can activate your parasympathetic responses and soothe brain inflammation.

4) Try Fragrance-Based Treatment & Special Essential Oils

The peppermint, rosemary, and lemon essential oils are types of scents which can support your brain function better. At the time when you breathe in these smells, it will make you much more alert, help you to think in a fast manner, and reduce your mental fatigue.

How to use it: You can use it in two ways. The first way, you can put 2 drops into a diffuser. The second way, you can put 2 drops on your handkerchief and breathe in the smell at the time of your study or work breaks.

5) Connect With Nature

For this you can walk in barefoot on the natural surfaces like grass or sand. This can definitely reduce the oxidative stress and properly balance your cortisol levels. Research says that this can enhance your emotional well-being and focus by resetting your internal biological clock and increasing sleep quality.

6) Try Neurobics

The neurobics are actually the brain-stimulating activities or workouts which include non-routine movements and senses. This is really interesting; I will give you some examples.
1) Brushing your teeth using your non-dominant hand

2) Change your route or take a new route to your work.

3) Close your eyes and play some memory games.

So what is the use of this exercise? These workouts can trigger your dormant neural pathways and clearly support you to rewire brain connectivity.

7) Optimize Your Light Exposure

What you can do here is stop using bright white lights after sunset. Instead of that, you can use:

• Amber or red light bulbs in the evening or night
• Get 15 minutes of morning natural sunlight within 1 hour after your wake-up.

If you start doing this every day, this can help your body to release melatonin at the correct time at night and thereby enhance the sleep quality and will also give you a stronger memory.

8) Consume Foods Rich in Choline for Neurotransmitter Health

Choline is actually a vitamin-like nutrient which is really important for the synthesis of acetylcholine. Acetylcholine is the neurotransmitter behind your memory and learning. But what foods all contain choline? I will tell you;

• Egg yolks
• Liver of chicken, beef, goat, or lamb - Even if you take one tablespoon, it is helpful.
• Cauliflower and broccoli
  

So, if you add these foods to your diet, it can definitely help you to improve your focus and memory within a few weeks.

9) Take Active Breaks

This is one of the most important points to note down. During your breaks, other than scrolling Instagram or watching YouTube videos, do some light physical exercises like jumping jacks or stair climbing just for 2-5 minutes. This can help to boost your brain-derived neurotrophic factor and flush out your mental fatigue more quickly.

10) Clear Your Mind With Daily Journaling

Actually, the brain fog is not only a result of physical problems; it also comes if you have too many thoughts, worries, or emotions in your mind. So spend just 5 minutes every day to write down your thoughts. Here you can write down about your

• Ongoing concerns and fears
• The plans that you haven't acted on.
• Things or situations that can lead to strong emotional responses.
  

If you practise this daily, then it can definitely clear your mind and reduce your stress.

Here are some Real-Life Inspirational Stories.

No.1

Because of his job, he was supposed to constantly sit in front of his laptop, and he was not having a regular eating routine. This imbalance leads to forgetfulness, and his mind feels blank and dull at the time of his meetings.

But later he understood that the main culprit is his poor lifestyle. So Aarav planned to adopt a healthy lifestyle. As part of this healthy lifestyle, he,

• Started wearing blue light-blocking glasses.
• Started intermittent fasting.
• Started doing 2 minutes of jumping jacks in each of his breaks.

In just 3 weeks' time, Aarav noticed that his mental clarity, focus, and thinking ability had been improved, and he also designed and developed a new mobile application to help people become more productive in their lives.

No.2

Mercy is a 50-year-old woman who is working from her home as a health & wellness blogger. After menopause, the hormonal changes or shifts in her body caused Mercy to suddenly pause during conversations, getting confused or feeling mentally blank. And she also felt difficulty in recalling some words or conveying her thoughts properly.

Because of these issues, Mercy seeks help from a doctor who usually combines modern medicine with natural treatment methods. He told Mercy to 

• Consume choline-containing foods.
• Take Lion's Mane mushroom supplements.
• Spent some time under moonlight to properly fix her sleep cycle.

In addition, she also started practicing yoga techniques and meditation. Within 5 weeks she was able to get rid of her brain fog, and she planned to write a new article on the topic 'clear mind and calm body'.

Now I will clear some of your common doubts regarding brain fog!

1) Can gut bacteria imbalance be a reason for brain fog?

Of course, yes. New studies say that an unbalanced or unhealthy gut, also called gut dysbiosis, can badly affect the brain, and it can enhance the brain inflammation and also reduce the production of important neurotransmitters such as serotonin and GABA.

You can boost your digestion with probiotic-rich foods. Learn more!

2) Is brain fog a reversible condition at any age?

Yes, definitely. Keep in your mind that your brain is like a muscle, and it has the ability to stay strong and improve even in your 70s. This ability is usually called 'neuroplasticity' (the capability of the brain to learn new things and create new connections at any age).

And keep your brain always sharp and active by,

Consuming nutritious food items.

Playing puzzle games

Learning and reading new things for cognitive stimulation

Sleeping well

3) Can any weather or climate cause brain fog?

Yes, mainly reduced sunlight exposure, which is common in the winter season, can reduce your vitamin D levels and disrupt your serotonin cycles.

And in hot and humid weather, your body will lose water slowly, but you won't be noticing it, and this can slightly dehydrate your cells and make you feel tired and slow.

4) Does a break from screens and devices really help?

According to some small studies, yes. If you are taking a 3 day break in nature without using your mobile phones or laptops, then it can increase BDNF, lower cortisol, and also improve your focus by almost 30 to 40%.

If you are ready to avoid using screens for just one weekend, it can help your brain to reset completely and feel mental freshness.

5) What is meant by 'tech-induced ADHD'? Does it really exist?

Tech-induced ADHD is not actually an official medical diagnosis. But if you are a person who uses too much technology, like mobile phones, social media, or games, then it can lead to some symptoms which are similar or identical to ADHD, like a very short attention span, acting impulsively, and very bad working memory.

But the good news is that if you are managing your screen time, then you can come out of these symptoms within a few weeks.

Conclusion (My Opinion)

The brain fog is very common nowadays. Even I'm also a person who experienced brain fog multiple times in my life. I personally believe that brain fog is a warning sign. That means the brain is working too much without adequate rest or not getting proper nutrients from the diet or exposed to excessive screen time and mental pressure.

But, to come out of this condition, you actually don't need to buy expensive supplements, and you don't want to follow any hard routines. What you really need is a smart plan that fits your lifestyle and your body.

You can begin your journey by choosing just one or two changes from the above list. Anyway, start small and choose which feels easy for you or most helpful for you.
