Anxiety is a feeling of unease, worry or fear. Everyone feels anxious at some point in their life, but for some people it can be an ongoing problem.
A little bit of anxiety can be helpful; for example, feeling anxious before an exam might make you more alert and improve your performance. But too much anxiety could make you tired and unable to concentrate.
Anxiety can have both psychological and physical symptoms. Psychological symptoms can include:
When you’re feeling anxious or stressed, your body releases stress hormones, such as adrenaline and cortisol. These cause the physical symptoms of anxiety, such as an increased heart rate and increased sweating.
Physical symptoms can include:
A little anxiety is fine, but long-term anxiety may cause more serious health problems, such as high blood pressure (hypertension). You may also be more likely to develop infections. If you’re feeling anxious all the time, or it’s affecting your day-to-day life, you may have an anxiety disorder or a panic disorder.
There are effective treatments available for anxiety and panic disorders, so do talk to your doctor if you think you may benefit from them.
