Anxiety is what we feel when we are worried, tense or afraid – particularly about things that are about to happen, or which we think could happen in the future. Anxiety is a natural human response when we perceive that we are under threat. It can be experienced through our thoughts, feelings and physical sensations. Most people feel anxious at times. It's particularly common to experience some anxiety while coping with stressful events or changes, especially if they could have a big impact on your life.
Like all animals, human beings have evolved ways to help us protect ourselves from danger. When we feel under threat our bodies react by releasing certain hormones, such as adrenaline and cortisol. These hormones:
make us feel more alert, so we can act faster
make our hearts beat faster, quickly sending blood to where it's needed most.
After we feel the threat has passed, our bodies release other hormones to help our muscles relax. This can sometimes cause us to shake.
This is commonly called the ‘fight, flight or freeze’ response – it’s something that happens automatically in our bodies, and we have no control over it.
Anxiety can become a mental health problem if it impacts on your ability to live your life as fully as you want to. For example, it may be a problem for you if:
your feelings of anxiety are very strong or last for a long time
your fears or worries are out of proportion to the situation
you avoid situations that might cause you to feel anxious
your worries feel very distressing or are hard to control
you regularly experience symptoms of anxiety, which could include panic attacks
you find it hard to go about your everyday life or do things you enjoy.
If your symptoms fit a particular set of medical criteria then you might be diagnosed with a particular anxiety disorder. But it's also possible to experience problems with anxiety without having a specific diagnosis. Our pages on self-care and treatment for anxiety problems offer suggestions for help and support.
