If you’re about to mix a sinus rinse, a jug of distilled water kept at room temperature is ready to measure. Freshly boiled water needs time to cool.
Key takeaways
- Room-temperature saline works without heating.
- Let boiled water cool before mixing and rinsing.
- Use the water volume listed on your saline packet.
What temperature should a sinus rinse be?
Use room-temperature or comfortably lukewarm saline for a sinus rinse. A guideline for adults with chronic sinusitis lists room temperature, about 68°F (20°C), as a practical option and advises against using a rinse straight from the refrigerator or hotter than 104°F (40°C). That upper limit is not a temperature to aim for.
If you keep distilled water at room temperature, you can measure it and mix a fresh rinse without heating it. If you’ve just boiled water, give it time to cool before you use it.
Choose safe water before checking warmth
Start with distilled, sterile or previously boiled and cooled water. Warm tap water can still carry germs that are safe to swallow but can cause infection inside your nose. Follow the FDA’s instructions for boiling and cooling rinse water if you’re preparing it from the tap.
Measure your water before adding saline
Once the water is ready, measure the amount specified in your saline directions. Plain water can sting even when it feels comfortably warm. Adding the right amount of saline powder makes the rinse more comfortable.
Follow your irrigator’s directions for use, then wash it and let it dry.
SinuAir pre-measured saline packets take the scooping out of your routine. Use the packet directions to match the powder to the water you’ve measured.
