Taking care of nasal hygiene is important from birth. Breathing through the nose is the only correct way of breathing, which is vital for the child's development and growth. A dry nose, accumulated impurities, secretion or swollen mucosa will prevent the passage of air through the baby's nose. This can cause restlessness, crying and irritability, and disrupt peaceful sleep and feeding. A blocked nose caused by colds or allergies may affect the health of the entire respiratory system. Seawater rich with minerals has a beneficial effect on the nasal mucosa by supporting its natural cleaning mechanisms.
