How your nose helps fight a cold

Coughs and colds due to viral infections can cause swelling in the nasal and sinus tissues.

When a mild upper respiratory infection develops in the nose and sinuses, the first symptoms tend to be a snotty, runny nose with lots of watery mucus. This is due to the nose trying to wash out the virus and inflammatory chemicals produced in the body in response to the infection. The mucus then begins to dry up, becomes thicker and even yellow/green in colour. This is a normal subsequent reaction and means your body is fighting the infection.If the mucus is diluted, thinned and washed out of the nose, it can help wash away germs and irritants and may result in temporary relief from congestion.

Benefits of nasal / sinus washing

Using a preservative-free saline nasal spray or a sinus wash may help clear and temporarily relieve congestion from colds and sinusitis * because they:

• Thin sticky and thick mucus
• Wash away inflammatory chemicals (that the cold virus has stimulated in the nasal tissues)
• Remove mucus plugs
• Moisturise the nasal tissues
• Help prevent scabbing in the nose.

Thinning and washing way excess mucus may also help clear the nose and relieve pressure in the sinuses.

Flo Saline Plus is a preservative-free, isotonic saline nasal spray with a gentle formula to help temporarily relieve nasal congestion.

Flo Sinus Care has been specifically formulated to closely mimic the body’s own tissue fluids and is a preservative-free wash that helps temporarily relieve both sinus and nasal congestion.
Ask your pharmacist about preservative-free saline solutions, sprays or washes. All Flo saline products are preservative-free
