Each day we breathe in approximately 10,000-11,000 litres of air and along with that, many irritants and allergens such as viruses, bacteria, mold spores, pet dander, dust, pollution and smoke.
The nose is situated at the entrance of the airway and protects the lower airway from the harmful effects of the breathed-in air. It acts like an efficient air-conditioning and filtration system. It warms, filters, and humidifies the breathed in air so that clean air is saturated with water vapour at an optimal temperature and is delivered to the lungs. Put simply, our nose is a wonderful machine!
The nose also acts as an early warning system that alerts us to the presence of airborne irritants or allergens. It is not surprising that the nose is considered “the gatekeeper of the lungs” so it makes good sense to care and look after the nose for good health. When nasal congestion symptoms strike, like a sniffly or stuffy nose, sneezing, runny nose or blocked nose, these are good indications that the nasal tissues are inflamed or irritated.
Did you know using a preservative-free saline nasal spray is a simple and positive thing you can do each day for your nose and respiratory health?
6 ways a preservative-free saline nasal spray benefits
- It helps flush out viruses in the nose where they are breathed in, invade and replicate.
- It cleanses nasal tissues to help maintain nasal immunity and functioning.
- It cleanses the nasal tissues before use of medicated nasal sprays may also improve their uptake.
- Thinning and diluting excess mucus in the nose and sinuses can help relieve sinus congestion, pressure and pain.
- It can help reduce viral load in the nose and as a result, reduce symptoms from colds and other Upper Respiratory Tract Infections.
- It can help reduce viral shedding in the nose and as a result, reduce the rate of infectivity (spread of virus).
When to use a preservative-free saline nasal spray
- For upper respiratory infections like colds or sinusitis
- For hay fever and before using medicated allergy nasal sprays
- For other respiratory allergies and before using inhaler medications
- After nasal surgery when the nasal passages are dried/crusty
- When breathing in cold, dry air i.e. airplane travel and in air conditioned environments.
If your nose is very blocked due a cold or an allergy, try a preservative-free nasal decongestant spray like Flo Rapid Relief for 3 days (for ages 12 and up with advice from your health professional).
A preservative-free nasal saline spray like Flo Saline Plus can be used daily and is also handy to have when out and about, to help wash away irritants in the nose when exposed to them. For children, preservative-free saline nasal sprays like Flo Baby or Flo Kids are useful and can be used at any angle for easy administration.
When using Flo: Always read the label. Follow instructions for use. If symptoms persist, talk to your health professional.
