Introduction

It was supposed to be a normal broadcast day. The cameras rolled, the lights warmed up, and I began speaking—until my mind suddenly went blank. A strange pause. A sentence left hanging mid-air. A moment of complete brain fog on live TV.

Within minutes, the clip went viral. Some viewers joked. Some expressed concern. Many related to it. What followed was a powerful, much-needed debate across India about overwork, stress, and the hidden mental load so many people carry.

Brain fog isn't a medical diagnosis by itself. It’s a symptom—often triggered by stress, burnout, overwork, poor sleep, anxiety, illnesses, or nutritional deficiencies. And my small on-air moment opened the doors for thousands to share their own.

This guide will help you understand brain fog, its causes, symptoms, treatments, prevention, and why taking mental health seriously is essential today.

What Is Brain Fog? 

Brain fog refers to a state of mental cloudiness, confusion, or difficulty thinking clearly. People often describe it as:

• “My mind feels heavy.”

• “I can’t think straight.”

• “I know what I want to say but the words don’t come out.”

Brain fog itself is not a disease—it is a signal from your body and brain.

Why My On-Air Brain Fog Moment Hit a Nerve

Millions of Indians experience similar moments daily: forgetting names, losing track mid-sentence, blanking out during meetings, or struggling to focus. But many ignore it because:

• Overwork is normalized

• Stress is considered “part of life”

• Mental health conversations still feel uncomfortable

• Sleep deprivation is glorified as productivity

A single on-air pause turned into a nationwide conversation about how the human brain responds when pushed too far.

Causes of Brain Fog 

Brain fog can happen due to one or more factors. Here are the most common:

1. Overwork 

Long working hours, tight deadlines, and lack of breaks overload the brain’s processing ability. Over time, cognitive fatigue sets in.

2. Stress & Anxiety

Chronic stress triggers cortisol release, affecting memory, focus, and decision-making.

3. Sleep Deprivation

Sleeping less than 6–7 hours regularly disrupts brain function.

4. Nutritional Deficiencies

Low levels of vitamin B12, iron, vitamin D, omega-3, and folate impair concentration.

5. Hormonal Changes

Thyroid imbalance, menopause, and postpartum changes can cause mental fogginess.

6. Dehydration

Even mild dehydration can affect cognition.

7. Medications

Some medicines (antihistamines, sedatives, antidepressants) may contribute.

8. Medical Conditions

• Thyroid disorders

• Diabetes

• PCOS

• Post-COVID syndrome

• Autoimmune disorders

• Depression

9. Poor Lifestyle Habits

Skipping meals, excessive caffeine, lack of exercise, and irregular routines worsen cognitive clarity.

Diagnosis: How Doctors Evaluate Brain Fog 

Doctors begin with a:

1. Medical History Review

Questions about stress, sleep, diet, work hours, medications, and emotional health.

2. Physical Examination

To rule out thyroid, neurological, or metabolic issues.

3. Lab Tests

Depending on symptoms:

• CBC

• Thyroid panel

• Vitamin B12

• Vitamin D

• Blood sugar levels

• Iron studies

4. Mental Health Screening

To check for anxiety, depression, or burnout.

Diagnosis focuses on finding the root cause rather than just treating the symptom.

Treatment Options for Brain Fog 

1. Managing Overwork

• Limit long hours

• Take micro-breaks

2. Stress Management

• Iron

• Omega-3 fatty acids

(Do not self-medicate. Dosage must be prescribed by a doctor.)

5. Treating Underlying Conditions

If due to thyroid, diabetes, or anxiety disorders, managing the root condition often improves fogginess.

6. Hydration

2–3 litres of water per day (adjust based on climate/needs).
