Feeling Anxious? Here’s What’s Happening in Your Brain and How to Calm It

Introduction

You’re about to give a presentation, your heart races, your palms sweat, and your mind spins with worst-case scenarios. Welcome to anxiety a natural human response that can go from helpful to overwhelming in a heartbeat.

In today’s fast-paced world, anxiety has become a buzzword, but it’s often misunderstood. Let’s unpack what it really is, what’s happening in your brain, the common symptoms, and most importantly, what you can do about it.

What Is Anxiety?

Anxiety is your body’s built-in alarm system a survival tool designed to alert you to danger. When it works properly, it helps you stay focused and react quickly in high-stress situations.

But sometimes, that system goes into overdrive, responding to everyday stressors as if they’re life-or-death situations. This is when anxiety becomes a problem persistent, intense, and often disconnected from real threats.

There are several types of anxiety disorders, including:

• Generalized Anxiety Disorder (GAD) – chronic worrying about everyday things

• Panic Disorder – sudden, intense fear or panic attacks

• Social Anxiety – fear of social interactions or being judged

• Phobias – extreme fear of specific objects or situations

Neurotransmitters Involved in Anxiety

Your brain chemistry plays a huge role in how anxiety shows up. Three key neurotransmitters are involved:

1. GABA (Gamma-Aminobutyric Acid):

This is your brain’s calming chemical. It slows down nerve activity and helps reduce feelings of fear and stress. Low levels of GABA can make it harder to "turn off" anxious thoughts.

2. Serotonin:

Known as the “feel-good” chemical, serotonin influences mood, sleep, and appetite. Low serotonin levels are linked to both anxiety and depression.

3. Norepinephrine:

This one gears you up for action. It's part of the “fight or flight” response and can cause your heart to race or palms to sweat. High levels are often found in people with panic disorders.

Imbalances in these neurotransmitters can tip your brain into an anxious state even when there’s no real threat present.

Common Symptoms of Anxiety

Anxiety doesn’t always look the same, but here are some common signs:

• Physical: Rapid heartbeat, muscle tension, stomachaches, sweating, dizziness

• Emotional: Irritability, restlessness, constant worry, feeling overwhelmed

• Cognitive: Racing thoughts, trouble concentrating, imagining worst-case scenarios

• Behavioral: Avoiding certain places, procrastination, needing constant reassurance

2 Effective Coping Strategies (And How to Use Them)

Managing anxiety isn’t about eliminating it entirely — it’s about learning how to calm your nervous system when it spikes. Here are two science-backed methods you can start using today.

1. Diaphragmatic Breathing (aka Deep Belly Breathing)

Why it works: Deep breathing activates your parasympathetic nervous system the part responsible for rest and relaxation helping to counteract the stress response.

How to do it:

1. Sit comfortably or lie down.

2. Place one hand on your chest, the other on your belly.

3. Inhale slowly through your nose for a count of 4, letting your belly rise (not your chest).

4. Hold your breath for 2–3 seconds.

5. Exhale slowly through your mouth for a count of 6, letting your belly fall.

6. Repeat for 3–5 minutes.

When to use it: Before a stressful event, during a panic attack, or daily as a preventive tool.

2. Cognitive Reframing

Why it works:Anxious thoughts often distort reality. Cognitive reframing helps you challenge those thoughts and replace them with more balanced, realistic ones.

How to do it:

1. Catch the thought: Notice when you’re spiraling e.g., “I’m going to mess this up.”

2. Challenge it: Ask yourself, Is this thought 100% true? What evidence do I have for and against it?

3. Reframe it: Replace it with a more helpful thought, like: “I’ve prepared, and even if I stumble, I’ll get through it.”

4. 
   

When to use it: In the moment of anxiety or as a journaling exercise to explore recurring thought patterns.

Final Thoughts

Anxiety can be overwhelming, but it's also manageable. Understanding the brain chemistry behind it and learning to work with your nervous system not against it is key.

The next time your anxiety kicks in, take a deep breath, remind yourself what’s really going on, and know that you’re not alone and you’re not powerless.
