Can EWOT Help With Brain Fog? Let’s Find Out

We’ve all been there, staring at a screen and re-reading the same line or walking into a room and forgetting why you went there. That frustrating, heavy, “why can’t I think straight?” feeling is what we call brain fog. And when you’re dealing with work, family, or 50 different things at once, brain fog can completely derail your day. What if there’s a natural way to clear your brain fog and feel sharp and focused again? Yes, I’m talking about Exercise with Oxygen Therapy, or EWOT in short, where you breathe in higher concentrations of oxygen while exercising. Wondering how that helps you get your brain back on track? Let’s break it down.

Understanding Brain Fog

Brain fog isn’t just “feeling a little tired.” It is a range of symptoms that can temporarily limit your cognitive function.

Brain fog is usually described as: 

  • Difficulty concentrating and paying attention

  • Confusion

  • Fatigue

  • Mental exhaustion

  • Trouble holding a conversation

  • Forgetfulness

  • Feeling detached or spaced out

  • Struggle doing multitasking

What can cause brain fog? Well, let’s take a look at some common causes.

  • Lack of sleep

  • Depression

  • Pregnancy

  • Menopause

  • Autoimmune conditions such as multiple sclerosis and lupus

  • Chronic Fatigue Syndrome

  • Some medications

  • Poor nutrition

  • Sedentary lifestyle

  • Chemotherapy treatment for cancer

  • Stress 

  • COVID-19

If you’re often noticing those signs, it’s high time you give your brain a little extra support. 

Why Your Brain Has a High Oxygen Demand

Did you know that your brain makes up only 2 percent of your body weight, yet it consumes around 20 percent of your body’s oxygen supply? Yes, that’s a huge share for such a small organ. 

Your brain needs oxygen for:

Energy production

Oxygen fuels chemical processes that are associated with thought, memory, and action. Without enough oxygen, your brain cells can’t generate the energy they need.

Neurotransmitter balance

Oxygen helps balance the levels of neurotransmitters such as dopamine, serotonin, and endorphins. Neurotransmitters are your body’s chemical messengers that influence mood, focus, and motivation. 

Healthy blood flow

When your body has good blood circulation, nutrients reach your neurons, and waste products get cleared away. Poor circulation means poor cognitive function.

Nerve signaling

Your brain runs on electrical signals. Brain cells or neurons use oxygen to send these signals. Without enough oxygen, communication slows down and thinking feels harder.

Because your brain is so oxygen-dependent, even minor drops in oxygen levels, due to stress, illness, shallow breathing, aging, or inactivity, can make your mind feel cloudy. What if you can supply more oxygen to your brain in a natural way? EWOT just does that. 

EWOT Basics

Exercise with Oxygen Therapy (EWOT) is exactly what it sounds like: You perform moderate exercise while breathing high-flow oxygen from an Oxygen Reservoir Bag through a specialized mask. Here’s what makes EWOT different from regular workouts:

  • You inhale 93-96% oxygen instead of normal air (which is only 21%)

  • Your heart pumps faster during exercise, so the oxygen is delivered more deeply and quickly

  • You get more oxygen into your cells, tissues, and organs than it would during regular exercise.

  • An EWOT session takes only 15 minutes. You don’t need to work out for an hour. Even short sessions can make noticeable changes in energy, focus, and clarity.

Now the big question is: How does EWOT actually help with brain fog? 

How EWOT Helps Clear Your Brain Fog

Let’s take a look at how Exercising with Oxygen can help you clear your brain fog and stay sharp and focused.

Increases Oxygen Supply to the Brain

When you engage in EWOT, your body absorbs more oxygen than usual. It’s no surprise that you feel clearer almost instantly, because your brain gets the fuel it needs. Simply put, more oxygen means faster cognitive processing, sharper focus, and better memory. 

Improves Blood Circulation

Studies show that exercise increases the blood circulation to the brain. So when you combine physical activity with supplemental oxygen, the benefits become even better.. What happens when your blood flow improves? The answer is simple: your brain gets more oxygen and nutrients to generate energy and think clearly. 

Increases Energy Levels

Did you know that your brain depends on mitochondria (your cell's powerhouse) for energy? Mitochondria need oxygen to create energy. More oxygen helps them to produce ATP (energy) efficiently. More ATP means better brain performance. When you perform EWOT regularly, you will experience less mental fatigue, more motivation, and clearer thinking all through the day.

Reduces Inflammation

Chronic inflammation is a hidden cause of brain fog. It disrupts neurotransmitter balance and slows neural communication. Exercising with oxygen helps you fight inflammation by improving blood flow, reducing oxidative stress, and supporting your immune system and joint health.

Supports Healing

If you are someone who notices brain fog as a lingering symptom of Lyme disease, Long COVID, or chemotherapy, EWOT can be a supportive tool. Better oxygenation helps your body’s natural healing processes work more efficiently. 

Regulates Stress Hormones

Exercise already releases endorphins, the feel-good chemicals in your brain. When combined with supplemental oxygen, this effect can be even stronger. You’ll start to notice better mood, reduced stress, and better emotional clarity.

Final Thoughts

We get it. Brain fog can make your life heavier than it needs to be, especially when it takes away your focus, drains your energy, and makes even simple tasks feel overwhelming. But you don’t have to live with it. Your brain is super-responsive to better oxygen supply and blood flow, and it can bounce back quickly when it gets the fuel it needs. Exercise with Oxygen Therapy (EWOT) gives your brain the combined benefits of exercise and supplemental oxygen and helps clear the brain fog and rebuild your energy. Why wait? Try EWOT and give your brain the oxygen advantage it’s been waiting for. 

Frequently Asked Questions

What can I expect after an EWOT session?

Many users report feeling mentally refreshed, almost like a mental reset.  You might notice your focus improving, your mood lifting, or your energy feeling more stable. Some users start to notice the improvements right after their first session.

How often should I do EWOT to clear the brain fog?

You can start with 3-5 sessions per week. It just takes 10-15 minutes per session, so they fit easily into your busy schedule. What matters most is consistency. Listen to your body and adjust the frequency and intensity as needed.

Is EWOT beginner-friendly?

Absolutely. You don’t need to be super fit or comfortable with intense workouts to start. You can go at your own pace, be it walking, cycling, or moving gently while breathing oxygen-rich air. If you have any pre-existing medical conditions, consult your healthcare provider before integrating EWOT into your daily routine.
