Why Brain Fog Seems to Be on the Rise in Our Community

At Sheen Vein (Aesthetics and Functional Medicine), we’ve noticed something over the past few years—more and more patients are coming in with the same frustrating complaint:

“I feel like I’m in a mental haze.”

This symptom—often described as brain fog—isn’t an official medical diagnosis, but it’s a very real experience. People with brain fog often report:

  • Difficulty focusing
  • Slower processing speed
  • Forgetfulness
  • Trouble finding words
  • Feeling mentally drained

While occasional mental fatigue can happen to anyone, we’re seeing a trend where brain fog is becoming more common and more persistent within our community.

Why Brain Fog May Be Increasing

The rise in reported brain fog likely isn’t due to a single cause—it’s the result of multiple overlapping factors that have become more prevalent in recent years.

1. Post-Illness and Post-Viral Effects

In the past few years, many people have experienced lingering symptoms after viral infections—particularly after COVID-19. Research has shown that post-viral inflammation can affect the brain, leading to ongoing cognitive symptoms like brain fog, fatigue, and memory issues.

2. Chronic Stress and Burnout

Stress levels in modern life are higher than ever. Whether it’s from work demands, family responsibilities, or ongoing uncertainty, chronic stress floods the body with stress hormones like cortisol. Over time, this can affect:

  • Sleep quality
  • Hormone balance
  • Blood sugar stability
  • Brain function

These stress-driven changes can make it harder to concentrate and think clearly.

3. Poor Sleep Quality

Many people in our community are sleeping less—or sleeping poorly—due to work schedules, screen time, or stress. Even if you’re getting “enough” hours of sleep, disruptions in sleep cycles can impair memory consolidation, focus, and alertness during the day.

4. Nutritional Deficiencies

A diet low in key nutrients—such as B vitamins, omega-3 fatty acids, magnesium, and antioxidants—can impact brain health. Vitamin D deficiency, which is common in our region due to limited sun exposure in certain months, has also been linked to cognitive changes.

5. Blood Sugar and Insulin Resistance

We’re seeing more cases of insulin resistance in our functional medicine practice. Fluctuating blood sugar can cause energy crashes and mental fuzziness, while chronic insulin resistance may increase inflammation in the brain.

6. Environmental Toxins and Poor Air Quality

Air pollution, mold exposure, and other environmental toxins can have neuroinflammatory effects. In some cases, long-term exposure can subtly affect memory, concentration, and mental stamina.

7. Sedentary Lifestyle

Many people are moving less due to desk jobs, remote work, and modern conveniences. Regular movement is essential for healthy blood flow to the brain, and without it, mental sharpness can decline.

Why Functional Medicine Is Key for Brain Fog

Brain fog is a symptom, not a root cause. At Sheen Vein (Aesthetics and Functional Medicine), our job is to figure out why it’s happening in each individual.

Our functional medicine evaluation looks at:

  • Nutrient status (vitamin and mineral levels)
  • Hormonal balance (thyroid, adrenal, sex hormones)
  • Blood sugar regulation
  • Inflammation markers
  • Gut health (imbalances in the gut microbiome can influence brain function)
  • Toxin exposure history

This allows us to create a personalized plan that addresses the underlying drivers of brain fog—not just the symptoms.

Strategies to Support Mental Clarity

While treatment plans are individualized, we often recommend:

  1. Improving Sleep Hygiene – Consistent bedtimes, limiting blue light at night, and optimizing the sleep environment.
  2. Balancing Blood Sugar – Eating nutrient-dense meals with adequate protein, fiber, and healthy fats.
  3. Nutritional Support – Using targeted supplements like B-complex vitamins, omega-3s, magnesium, and vitamin D.
  4. Movement and Circulation – Incorporating regular physical activity, even short walks throughout the day.
  5. Stress Management – Techniques like deep breathing, meditation, or gentle yoga to reduce cortisol.
  6. Addressing Gut Health – Supporting digestion and microbiome balance, which can influence brain chemistry.

A Growing Community Concern

It’s clear that brain fog isn’t just an occasional annoyance—it’s becoming a quality-of-life issue for more people in our area. When mental clarity fades, it can impact work performance, relationships, and overall happiness.

The good news is that brain fog is often reversible when the root causes are identified and addressed. Patients in our clinic often report significant improvement in focus, memory, and energy once their plan is in place.

Final Thoughts

Brain fog may be more common now, but it doesn’t have to be a permanent part of your life. If you’ve been feeling mentally sluggish, forgetful, or easily overwhelmed, it’s worth getting to the bottom of it.

At Sheen Vein (Aesthetics and Functional Medicine), we use a personalized, root-cause approach to uncover why brain fog is happening and how to restore your mental clarity—so you can feel like yourself again.
