You could also try:
- Breathing slowly in through your nose and out through your mouth, with your lips together like you’re gently blowing out a candle
- Sitting upright in a chair
- Relaxing your shoulders, so you’re not hunched
- Leaning forward slightly – support yourself by putting your hands on your knees or on something stable like a chair.
According to the NHS, you should try not to panic if you’re feeling breathless – this can make it worse.
However, if you’re so breathless that you’re unable to say short sentences when resting or your breathing has suddenly got worse, the NHS recommends going to A&E immediately or calling 999.
If you have one of the main symptoms of coronavirus – a high temperature, new, continuous cough or a loss or change to your sense of smell or taste – get a test as soon as possible.
