4. Correct Breathing
Speaking of getting your breathing under control, another good way to potentially ease your diaphragm and regain control is to practice correct breathing – or ‘belly breathing’ as it is also known.
To do this, your first step is to relax the abdominal wall so that your gut hangs out. This will in turn cause the diaphragm to drop into the abdominal cavity, which opens up the bottom of the lungs and allows you to take in more air. Most of us forget this step and breathe by starting with the chest.
Now fill the lungs from the bottom and only once you’ve done that, expand the chest too. It’s hard to do while hiccupping but it requires concentration and control while also relaxing the sympathetic nervous system.
