Inhale pure air. Why should that be emphasized?
Inhaling pure air increases oxygen supply to mother and baby. It purifies the blood and improves sleep. We encourage our mothers to get fresh air in their houses and bedrooms. As for labor, I recommend the slow relaxed breathing from the diaphragm instead of breathing fast, to avoid hyperventilation. Slow relaxed breathing will expend less energy so the mother won’t be so tired. This also helps ease the pain that comes with contractions.
