Physiological saline solution is an indispensable part of our daily lives, especially for maintaining good nasal hygiene and caring for our eyes. It is a sterile aqueous solution of water and sodium chloride, with properties similar to those of our own bodies. In this article, we take a look at the many uses of saline solution, as well as its health benefits.

Composition of saline solution

Saline is a saline solution containing mainly water and sodium chloride. The salt concentration of this solution is generally 0.9%, which corresponds to the salt content of our blood plasma. This is why it is referred to as "serum" and "physiological", as it is close to the fluids naturally present in our bodies.

The different forms of saline

Physiological saline solution comes in a variety of forms:

• Ampoules: These are small doses of saline intended for single use only. Once opened, they should not be stored.
• Sprays: These bottles diffuse a fine mist of physiological saline. They are ideal for daily nasal hygiene, especially for children.
• Multi-dose solutions: These come in bottles with a dropper, and can be used several times before being discarded.

Physiological saline solution uses

Nasal hygiene

Physiological saline solution is very useful for good nasal hygiene. It cleans and moistens nasal mucous membranes, while removing impurities and allergens from the nose. We recommend using saline at least once a day, to prevent ENT infections (colds, sinusitis, ear infections) and improve breathing.

How do I use saline solution for nasal hygiene?

To wash your nose with saline, simply follow these simple steps:

1. Tilt your head to one side, over a washbasin.
2. Gently insert the tip of the spray or ampoule into the upper nostril.
3. Apply pressure to the spray or ampoule to draw saline into the nostril.
4. Allow the saline to drain through the lower nostril, breathing through your mouth.
5. Repeat the operation for the other nostril.

Note: If you use an ampoule, be careful not to share it with other people, to avoid transmitting germs.

Eye care

Physiological saline solution is also an effective way of caring for your eyes, especially in cases of irritation caused by fatigue, pollution or contact lens wear. It gently rinses the eye, removing particles and impurities that can cause discomfort.

How do I use saline for eye care?

To rinse your eyes with saline, follow these instructions:

1. Wash your hands thoroughly before starting.
2. Open the eye to be treated by gently pulling on the eyelids.
3. Bring the pipette or ampoule close to the eye, without touching the surface.
4. Drip a few drops of saline onto the eye.
5. Blink to distribute the saline and help remove impurities.
6. Repeat if necessary.

Other uses for saline solution

In addition to nasal hygiene and eye care, saline can also be used for :

• Cleanse wounds: Rinse out abrasions, cuts and other small wounds, removing dirt and bacteria.
• Moisturize skin: applied as a compress, it soothes and moisturizes irritated or dry areas.
• Moisturize oral mucosa: Sprayed into the mouth, it relieves dry mouth and throat irritations.

Precautions for use and contraindications

Saline is safe and suitable for all ages, including infants. However, certain precautions should be taken to avoid the risk of infection or irritation:

• Check the expiration date before use.
• Do not share saline ampoules or sprays with others.
• Dispose of ampoules after use, even if there is still product inside.
• Do not use saline if the packaging is damaged or already opened.

If in doubt about how to use saline, ask your doctor or pharmacist for advice.
