3 Ways That Anxiety Affects Our Bodies

The NHS defines anxiety as:

“a feeling of unease, such as worry or fear, that can be mild or severe”.

Anxiety UK suggest that 1 in 6 teenagers will experience anxiety. This means that on average there will be around 5 children in any given classroom experiencing anxiety.

Anxiety is a natural reaction to stress. Anxiety is a normal reaction and response which everyone experiences. Anxiety can affect children and adolescents through their feelings, thoughts and behaviours in their bodies. Anxiety can be made worst when children experience stressful situations. However, anxiety can become heightened, destructive or persist for long periods of time for some children.

Anxiety can leave us feeling:

  • apprehensive
  • panicked
  • worried
  • tense
  • irritable
  • uncertain
  • nervous
  • on edge

Anxiety creates a feeling that something bad or unpleasant might happen in the future. It is triggered by our brain’s individual perception of the environment. We will each interpret the environment in our own unique way depending on life experience, developmental stage, age, resilience and self-esteem. As our brain interprets the world around us it creates a set of responses.

If we consider how the brain develops, it has three key layers:

AMYGDALA – The threat centre – it asks ‘am i safe?’ ‘am I happy?’

LIMBIC BRAIN – The emotion centre – it creates emotional responses to the amygdala’s answers

PREFRONTAL CORTEX – Logic and reasoning – this does not develop until we are 12 and takes until we are 25 to fully develop


When the amygdala decides ‘I am NOT safe and I am NOT happy’ then it triggers the limbic brain and this creates feelings of anxiety. This creates a sensation that we need to ‘get away’ from the stressor or trigger, by creating a feeling of worry or panic. Anxiety creates different signs and symptoms in each individual.


This can create many different responses:


Physical sensations in the body such as heart racing, stomach aches, nausea, panic, breathlessness, headaches, sweating, coldness, restlessness……


Anxiety creates different thoughts in our minds, these can be catastrophizing (looking at worst case scenarios) – irrational thoughts – distortions hypothesising (what if) – negative thoughts – intrusive thoughts – these can be very alarming and upsetting for young people. These are fuelled by the ‘I am NOT safe I am NOT happy’ feelings and are encouraging our brain to leave for safety – even if we are not at risk.


In some cases, anxiety can cause physiological changes in the body. This can be through weakness or fatigue, stomach aches or digestive issues, headaches and migraines, insomnia and sleep issues, excessive yawning, tremors, phantom smells or sounds, shortness of breath, dizziness, spots and acne.

What do we do?
