Experiencing shortness of breath can be scary. In some cases, having trouble breathing can be unpleasant but not a sign of anything serious. However, it could also be a sign that you need to seek medical treatment.

If you’re not sure, we’ve provided some helpful information below. But if you are worried, it’s usually best to talk to your doctor to get to the bottom of your symptoms.1

It’s worth noting here that shortness of breath may be a symptom of the COVID-19 coronavirus illness. If you are experiencing other symptoms, like a cough, loss of taste or smell and a fever, follow your local guidelines to understand what you need to do next.

What does shortness of breath feel like?

There is a range of breathing difficulties you might experience, and they all feel slightly different. It’s useful to know the difference so that you can better identify what’s happening.

Shortness of breath usually feels like a winded sensation, or like you are unable to take a full breath. The feeling is very similar to how you might feel after doing exercise or climbing a big flight of steps. However, it can happen at any time (even at rest).2

Generally, shortness of breath feels like you can’t get enough air into your lungs. You might feel like you have to breathe more quickly too.3

Different causes of shortness of breath

There could be a lot of causes of shortness of breath and finding out the reason why you feel breathless may help you find strategies to manage the symptom. Some of the causes are more serious than others, so always speak to your doctor if you are worried. In an urgent situation, always phone your local emergency services.

  • A cold or chest infection
  • Being overweight
  • Smoking
  • A panic attack or anxiety
  • Allergies
  • Asthma
  • Chronic obstructive pulmonary disease (COPD)
  • Other respiratory health conditions

It’s usually best not to try and self-diagnose when you are experiencing shortness of breath. Your doctor will be able to investigate your symptoms further and find the best treatment plan for you.

How to help stop shortness of breath

Any treatment for shortness of breath depends on the underlying cause. That’s why it’s essential to get to the bottom of your symptoms to help improve your breathing.
