“It’s just my nerves” – why anxiety hides in the body

Many older adults describe anxiety without ever using the word “anxiety”. Instead, they say:

• “My nerves are bad.”
• “My heart is always jumping.”
• “I feel sick with worry.”
• “I can’t settle – I’m up and down all day.”

In later life, anxiety often arrives as physical symptoms first and thoughts second. You might notice:

• Heart racing, fluttering or pounding.
• Shortness of breath or a feeling you can’t get a full breath.
• Dry mouth, butterflies, churning stomach or diarrhoea.
• Dizziness, light-headedness or “wobbly” legs.
• Tightness in the chest, shoulders or jaw.
• Needing the toilet more often, especially before appointments or phone calls.

Here is the rare piece that is usually missed: your brain is constantly predicting danger based on your history. If you have lived through poverty, illness, racism, war, bereavement, caring responsibilities or sudden losses, your “alarm system” may be tuned to a more sensitive volume. In older age, with health worries and money pressures, that alarm can easily become stuck on “high”.

Anxiety is not you “being silly” – it is your nervous system trying to protect you, but misjudging the level of threat. 🔔

Important safety note: never assume it’s “only anxiety”

Because anxiety can cause chest pain, breathlessness, dizziness and tummy pain, there is a risk that serious symptoms get written off too quickly – by the person or sometimes by others. Especially in later life, it is vital to remember:

• Chest pain, sudden breathlessness, collapse, new weakness in face or limbs, or sudden confusion could be signs of a medical emergency.
• If symptoms come on suddenly, are very intense, or feel different to your usual pattern, you should seek urgent help – call 999 or NHS 111 according to NHS advice.
• Only a medical professional, with proper assessment, can say “this is anxiety” with confidence.

This doesn’t mean every flutter is a heart attack. It means your safety comes first. Once emergencies and physical conditions have been checked for and treated, what’s left might well be anxiety – and that is worthy of proper care too.

How anxiety in older adults can look different

Many leaflets about anxiety are written with younger people in mind. In older adults, it can look and feel different:

• More physical, less “panic attack” language. You may feel all the sensations of panic but describe them as dizziness, “funny turns” or “my blood pressure.”
• Focused on health and family. Worries often centre on illness, falls, money, housing, grandchildren or leaving a partner alone, rather than work or exams.
• Mixed with grief and caring strain. Uncertainty about the future of a partner with dementia, for example, can fuel long-term anxiety.
• Hidden under “keeping calm”. Some older adults have been praised all their lives for being “strong” or “never making a fuss”, so the anxiety runs quietly inside while the outside looks composed.
• Entangled with physical conditions. Heart disease, lung disease, pain conditions, thyroid problems and medicines can all interact with anxiety symptoms.

This is why we treat anxiety in later life as a whole-person condition. It sits inside the same body that carries your medical history, cultural story and caring responsibilities.

The body–brain loop: what is actually happening inside 🧠

Think of your brain as a sensitive prediction machine. All day, it quietly asks:

• “Am I safe?”
• “Can I cope with what’s coming?”
• “What happened last time I was in this situation?”

If your brain decides the answer might be “no”, it sends signals down the body:

• The heart speeds up to prepare for action.
• Breathing becomes faster and shallower.
• Blood is moved away from digestion towards muscles, causing dry mouth and churning stomach.
• Muscles tense, ready to move, leading to aches and trembling.

Then the loop completes: your brain notices your racing heart and tight chest and thinks, “I must be in danger” – which sends more alarms. This is why anxiety often feels as if it is “living in the body”.

Breaking this loop partly involves calming the body (through breathing, movement and environment) and partly involves giving the brain a more accurate story about what’s happening.

Words you can use to describe anxiety to your GP or nurse 🗣️

You do not need psychological jargon. Clear, concrete descriptions are more useful. You might say:

Opening the conversation

• “I’d like to talk about my worry and anxiety today, because it’s affecting my daily life.”
• “My body feels on edge most of the time and I’d like to understand why.”
• “I’m often frightened there’s something seriously wrong, even when tests are okay.”

Describing physical symptoms

• “My heart often races or pounds, especially when I’m thinking about health or money.”
• “I get short of breath and tight in the chest when I’m anxious – it tends to come in waves and eases when I calm down.”
• “My stomach is often in knots; I go to the toilet more when I’m worried.”
• “I feel shaky and light-headed, like I might pass out, but my tests so far have been normal.”

Describing thoughts

• “My mind jumps to the worst-case scenario very quickly.”
• “I replay conversations and appointments for hours afterwards.”
• “At night, thoughts go round and round and I can’t switch them off.”

Describing impact

• “I avoid going out because I’m scared I’ll have an ‘episode’.”
• “I keep calling services for reassurance, but the relief doesn’t last.”
• “Because of anxiety, I sometimes miss tablets, meals or appointments.”

If speaking feels too hard, you can write these sentences on paper and hand them over. Our article “How to Talk to Your GP About Mood Without Feeling Ashamed” offers extra phrases if you feel embarrassed.

Home environment: reducing hidden anxiety triggers 🏡

Homes can quietly increase anxiety without us noticing. Small environmental tweaks can calm the nervous system:

Everyday routines that gently lower anxiety

Anxiety rarely disappears with one big decision. It usually softens through repeated small, body-based routines – especially those that combine light, breath, movement and connection. Our companion article “Simple Daily Routines That Support Mood” explores this in detail. Here, we focus on routines that specifically help anxiety.

Breath routine (even if you “don’t do relaxation”) 🌬️

You don’t have to sit cross-legged or close your eyes. Try this sitting upright in a chair, feet on the floor, hands resting on your thighs or tummy:

• Breathe in gently through your nose for a count of 4.
• Pause for a brief moment (1–2 seconds).
• Breathe out slowly through your mouth for a count of 6.
• Repeat for 1–3 minutes, or as long as feels comfortable.

The longer out-breath tells your nervous system that you are not in immediate danger. Doing this regularly trains your body to come down from “high alert” a little faster.

Movement routine 🤲

• Do shoulder rolls forward and back while seated.
• Gently clench and release fists and toes.
• Stand up and sit down from a sturdy chair a few times, holding on if needed.

Movement helps burn off some of the adrenaline that anxiety produces. Our PHAT sessions – and blogs like “Chair Exercises You Can Do While the Kettle Boils” and “How Group Exercise and Social Contact Protect the Brain” – show how you can do this safely, even with long-term conditions.

Connection routine 📞

• Agree a regular time each week when you speak to someone you trust about how you’ve really been – not just the weather.
• Let them know that some weeks you might be more anxious and need to talk, other weeks you might be quiet.
• Consider using PHAT Zoom groups as a safe place to say, “My worry has been bad this week,” without having to explain everything in detail.

Loneliness can intensify anxiety signals. Our article “Loneliness in a Busy World – Why It Hurts the Body Too” explains how isolation affects sleep, pain and heart health as well as mood.

Talking to loved ones about anxiety without feeling weak

Many older adults feel ashamed to admit anxiety to family. They worry about being seen as “a burden”, “negative” or “ungrateful”. Yet families often sense something is wrong and feel shut out.

You might try phrases like:

• “My body has been on high alert lately – heart racing, poor sleep – and I think it might be anxiety.”
• “You may not see it from the outside, but inside I feel tense most of the time.”
• “I’m telling you this not to worry you, but so you understand why I’m more tired or jumpy.”
• “What would help most is… (for example: a regular check-in call, help with appointments, patience if I cancel plans when I’m overwhelmed).”

If you’re caring for someone with anxiety, our other PHAT mental health articles – including “When Everyday Sadness Becomes Something More” and “Bereavement, Loss and Life After Caring” – can help you understand how worry, sadness and grief can overlap.
