Breathing. It's something we do naturally without giving a second thought, but could we be suffering a range of symptoms due to not doing it right?
According to regenerative medicine expert Dr Frances Pitsilis, disordered breathing, or hyperventilation syndrome, is becoming increasingly common.
The problem can come on as part of a range of symptoms tied to a chronic illness, or can be triggered to one of the most common complaints of our modern lives - stress.
"These days, when people are living a more stressful life, its easy for them to slip in in to the sort of breathing that you do when you're feeling at risk," says Dr Pitsilis.
