Why Anxiety Feels So Physical

Your Body Is Responding to an Alarm

When your brain senses a threat, it prepares your body to act. That response can start while you are sitting still. A thought about take-off may be enough.

Your heart may beat harder. Muscles tighten, hands shake and your stomach feels unsettled. These feelings are real. They are also recognised features of anxiety.

Why the Feelings Can Grow

Sometimes the sensation itself becomes the next trigger:

My heart pounds → "I won't cope" → more alarm → a harder-pounding heart.

This is sometimes called fear of the fear. You begin watching your body for the next sign, which gives each small change more attention.

Noticing the pattern gives you another response: "I've felt this with anxiety before. I can follow my plan."

Why Breathing Matters

When you breathe more than your body needs, you can breathe out too much carbon dioxide. That change can contribute to light-headedness and tingling.

The aim is comfortable, gentle breathing. You don't need to fill your lungs as much as possible or force a long count. Let your breath move easily. Read why breathing helps.

Try a Gentle Response

For symptoms you recognise from your usual anxiety:

1. Name the pattern: "My alarm is active."
2. Soften what you can: loosen your jaw and rest your hands.
3. Let your breathing be gentle. Skip a hold if it feels uncomfortable.
4. Look around you. Notice the seat fabric, a colour or the words on a page.

You don't need to keep checking your pulse to see whether this is working. Let a little time pass. If focusing on your breath feels uncomfortable, use grounding instead.

When to Ask for Help

Don't assume every symptom is anxiety. If you have chest pain, new or unusual symptoms, or think you may be unwell, tell the crew promptly. On the ground, seek medical help.

If fear of bodily sensations keeps limiting your life, a talking therapy called CBT (which helps you change unhelpful thoughts and habits) can help. A therapist may guide you through planned practice with bodily sensations. They can assess what is appropriate for your health.
