You can support healthy blood oxygen levels through regular physical activity, slow and controlled breathing exercises, and maintaining good hydration. Practices such as pranayama may also help improve breathing control. Eating iron-rich foods can support healthy haemoglobin levels, while avoiding smoking helps protect lung function. However, these measures cannot correct low blood oxygen caused by an underlying medical condition. If your pulse oximeter consistently shows low oxygen levels, seek medical attention rather than relying on home remedies. If your reading is 92% or lower, seek prompt medical advice; a reading of 88% or lower requires immediate medical attention.
