Stress Can Affect Both the Brain and the Body
Stress is not simply “feeling worried.” It is a whole-body response to pressure, demands or situations that feel difficult to manage. Short periods of stress can be normal, but when pressure continues without enough opportunity to recover, it can begin to affect physical health, emotional wellbeing, thinking and everyday functioning.
Physical Effects of Stress
Prolonged stress may contribute to:
Headaches • muscle tension • jaw clenching • digestive problems • nausea • changes in appetite • disturbed sleep • fatigue • increased heart rate • sweating • feeling shaky or restless • aches and pains
Some people may notice physical symptoms before they recognise that they are feeling stressed.
Stress Can Affect Thinking Too
When the brain is dealing with ongoing pressure, it can become harder to:
Concentrate • remember information • organise tasks • prioritise • make decisions • solve problems • process instructions • switch between tasks
Someone may know exactly how to do their job but temporarily find familiar tasks much more difficult.
Emotional Signs Can Include
Irritability • anxiety • frustration • low mood • feeling overwhelmed • reduced confidence • emotional exhaustion • tearfulness • feeling detached or shutting down
People respond to stress differently. One person may become visibly anxious, while another may become quieter, withdrawn or appear emotionally flat.
What Might This Look Like at Work?
An employee experiencing prolonged stress may:
Take longer to complete tasks • make more mistakes • struggle with deadlines • forget information • avoid conversations • become quieter • appear irritable • need more breaks • find meetings overwhelming • struggle to start tasks • experience reduced motivation or confidence
These changes should not automatically be interpreted as poor performance, laziness or lack of commitment.
They may indicate that the person is experiencing more pressure than they currently have the capacity or resources to manage.
What Can Help?
Support might include:
Clearer priorities • manageable workloads • realistic deadlines • regular breaks • quieter working spaces • flexible working • written instructions • supportive check-ins • temporary changes to duties • appropriate workplace adjustments
Remember
Stress is not always visible.
Someone can continue working, smiling, communicating and meeting responsibilities while experiencing significant stress internally.
Recognising the signs early and creating opportunities for support, recovery and open communication can help prevent prolonged stress from developing into exhaustion or burnout.
