There are several ways to increase your blood oxygen levels at home naturally. Options include:
pursed lip breathing
allowing fresh air into your home
quitting smoking or avoiding secondhand smoke
eating a well-balanced diet
If your blood oxygen level is too low, you may need supplemental oxygen to boost your oxygen saturation.
Home supplemental oxygen is a medication, and a doctor must prescribe it. It’s important to follow their advice on how home oxygen should be used to avoid complications.
