If you have impurities in your nasal passages, this can lead to numerous health issues, including hay fever and colds. Since Sterimar Congestion Relief Nasal Spray washes and clears, it encourages good nasal health and helps to stop colds.

Sterimar is a hypertonic nasal spray solution uniquely formulated with pure seawater. It's also enriched with copper, which helps to swiftly unblock nasal congestion (osmosis effect) caused by sinusitis and colds and remove even thick mucus, allowing you to breathe more comfortably. 

While many believe blocked and runny noses cause congestion, this isn't the case. Congestion is actually due to inflammation from a specific irritant that leads to nasal tissue swelling, which makes the nostrils narrow. As such, breathing through the nose becomes incredibly difficult. If you suffer from cold and flu symptoms, a runny nose is typically part and parcel of congestion, making breathing tricky.

The main difference between both products is that you can use the Isotonic variant regularly and long-term. The Sterimar Hypertonic Congestion variant includes copper, which is more useful against illness and is commonly for shorter-term use.
