Journal #9. Anxiety, stress and brain health
Anxiety, stress and brain health
Anxiety is a common experience, but it can look and feel very different from person to person. For some, it is persistent worry or racing thoughts. For others, it may show up physically: tension, poor sleep, restlessness, a tight chest, digestive changes or difficulty concentrating.
Occasional anxiety is part of being human. It can help us recognise risk, prepare for an important event or respond to a challenging situation. But when anxiety becomes persistent, intense or starts affecting everyday life, it deserves proper attention and support.
The brain, stress and inflammation
Researchers are continuing to explore the relationship between anxiety, stress, the immune system and inflammatory processes in the body.
Inflammation is a normal part of the body’s protective response to illness or injury. The brain and immune system also communicate closely, and prolonged stress can affect both systems. Some studies have found associations between anxiety disorders and markers of inflammation, but this is an evolving area of research.
It is important not to oversimplify that relationship. Anxiety does not have one single cause, and inflammation is not a diagnosis for anxiety. Genetics, life experiences, trauma, sleep, physical health, hormones, substance use, social circumstances and stress can all play a role.
What we do know is that prolonged stress can affect how the brain and body function. It can make it harder to sleep, concentrate, regulate emotions and recover between demanding periods.
Supporting your nervous system and cognitive performance
There is no one-size-fits-all solution for anxiety. The right support depends on the person and their circumstances.
For many people, a foundation of regular sleep, movement, nutritious food, reduced alcohol intake, time outdoors and meaningful connection can help support overall mental wellbeing. Mindfulness, breathing practices, yoga or other relaxation techniques may also be useful tools for managing stress.
These habits are not a replacement for clinical care. They can be part of a broader plan that includes support from a GP, psychologist, counsellor or other qualified health professional.
If anxiety is persistent, worsening or interfering with work, relationships, sleep or daily activities, speaking with a health professional is an important next step. If you feel at immediate risk of harming yourself or unable to stay safe, contact emergency services or a local crisis service straight away.
Support your cognitive performance
The habits you practise every day have the biggest influence on how your brain performs.
