Physiotherapist Marlies Ziegler shows eight exercises that help clear mucus from the bronchi in patients with colds, bronchitis and chronic lung diseases. This time exercise 1 ‘Bow and arrow while lying down’.

By doing certain exercises, mucus in the lungs can be mobilised so that it can be expectorated more easily and quickly.
Mucus forming in the lungs during an infection is a normal physiological reaction. The goblet cells produce more mucus so pathogens can be quickly transported out of the system. At the same time, the mucous membranes become swollen because many immune defence cells are being transported to the site of the infection. More mucus and swollen mucous membranes constrict the bronchi, which is also where air flows. So breathing becomes more difficult.
On the PARI blog, we show eight exercises that help clear mucus from the bronchi. This time, physiotherapist Marlies Ziegler explains the exercise ‘Bow and arrow while lying down’.
We asked Marlies Ziegler this question. She is a physiotherapist who specialises in respiratory physiotherapy and who every day works with patients who have chronic problems with clearing mucus from their lungs and bronchi. So she is well versed in effective exercises for mobilising mucus in the lungs. Not only are these exercises suitable for patients with chronic lung diseases such as COPD, cystic fibrosis, PCD and chronic bronchitis, they are also appropriate for times when the lungs and bronchi are acutely congested with mucus due to colds, bronchitis or pneumonia.
Marlies Ziegler knows from experience that the exercises work. The reason is that “the exercises have a positive effect on the flexibility of the chest, the spine and the ribs. Breathing is altered by this increased flexibility and the mucus can be cleared better.”
To achieve the best possible result, all of the exercises should be synced with your breathing. Syncing one’s breathing and movements can cause fluctuations in the bronchi in time with one’s breathing, enabling the air to get in behind the mucus. The mucus loosens and can be transported out of the lungs more easily. This works even better if you hold your breath for a short time after inhaling (if possible, slowly count to three).
This exercise mobilises the cervical spine and the ribs. The ‘bow and arrow exercise’ is a good way to prepare your body to do the ‘screw’ exercise. How to do this exercise:
Make sure to synch your movements with your breathing. Repeat this exercise for 5 to 10 breaths. Then switch to the other side.
