A panic attack is a feeling of sudden and intense anxiety.
Panic attacks can also have physical symptoms, including shaking, feeling disorientated, nausea, rapid, irregular heartbeats, dry mouth, breathlessness, sweating and dizziness.
The symptoms of a panic attack are not dangerous, but can be very frightening.
They can make you feel as though you are having a heart attack, or that you are going to collapse or even die.
Most panic attacks last somewhere from five minutes to half an hour.

How to handle a panic attack
Professor Paul Salkovskis, Professor of Clinical Psychology and Applied Science at the University of Bath, says it's important not to let your fear of panic attacks control you.
"Panic attacks always pass and the symptoms are not a sign of anything harmful happening," he says. "Tell yourself that the symptoms you're experiencing are caused by anxiety."
He says don't look for distractions. "Ride out the attack. Try to keep doing things. If possible, don't leave the situation until the anxiety has subsided."
"Confront your fear. If you don't run away from it, you're giving yourself a chance to discover that nothing's going to happen."
As the anxiety begins to pass, start to focus on your surroundings and continue to do what you were doing before.
"If you’re having a short, sudden panic attack, it can be helpful to have someone with you, reassuring you that it will pass and the symptoms are nothing to worry about," says Professor Salkovskis.
Breathing exercise for panic attacks
If you’re breathing quickly during a panic attack, doing a breathing exercise can ease your other symptoms. Try this:
Breathe in as slowly, deeply and gently as you can, through your nose.
Breathe out slowly, deeply and gently through your mouth.
Some people find it helpful to count steadily from one to five on each in-breath and each out-breath.
Close your eyes and focus on your breathing.
You should start to feel better in a few minutes. You may feel tired afterwards.

Ways to prevent panic attacks
"You need to try to work out what particular stress you might be under that could make your symptoms worse," says Professor Salkovskis. "It's important not to restrict your movements and daily activities."
Doing breathing exercises every day will help to prevent panic attacks and relieve them when they are happening.
Regular exercise, especially aerobic exercise, will help you to manage stress levels, release tension, improve your mood and boost confidence.
Eat regular meals to stabilise your blood sugar levels.
Avoid caffeine, alcohol and smoking – these can make panic attacks worse.
Panic support groups like No Panic have useful advice about how you can effectively manage your attacks. Knowing that other people are experiencing the same feelings can be reassuring.
Cognitive behavioural therapy (CBT) can identify and change the negative thought patterns that are feeding your panic attacks.
Is it panic disorder?
If you feel constantly stressed and anxious, particularly about when your next panic attack may be, you may have panic disorder.
People with panic disorder may avoid situations that might cause a panic attack. They may also fear and avoid public spaces (agoraphobia).
"There's no quick fix, but if your attacks are happening time after time, seek medical help," says Professor Salkovskis.
Being overweight may not be as unhealthy as it was 40 years ago," BBC News reports. New research has found a body mass index (BMI) of 27 is linked to the lowest rate of death – but someone with a BMI of 27 is currently classed as being overweight. BMI is a score calculated by dividing your weight (usually in kilograms) by the square of your height (usually in metres and centimetres). Currently, a BMI of 25 to 29.9 is classified as being overweight. Researchers looked at 120,528 people from Copenhagen, recruited from 1976 to 2013, and separately compared those recruited during the 1970s, 1990s and 2000s. They were followed up until they died, emigrated, or the study finished. The BMI linked to the lowest risk of having died from any cause was 23.7 in the 1970s group, 24.6 in the 1990s group, and had further risen to 27 in the 2003-13 group. It may be the case that the suggested upward shift in optimal BMI is the result of improvements in preventative treatments for weight-rela...
