Dry indoor air can leave the nose and throat uncomfortable during winter. A clean humidifier may help with dryness, but too much moisture and poorly maintained equipment can create problems. EPA: Use and Care of Home Humidifiers

Use humidity carefully

Check the humidity in your home with a hygrometer and use a humidifier only when needed. EPA advises keeping indoor relative humidity from exceeding 50%. If condensation develops on windows or nearby surfaces become damp, reduce the humidifier output or its use. EPA: Humidity Precautions

For portable humidifiers, empty and dry the tank and refill it daily. EPA recommends cleaning portable units every third day; also follow the manufacturer’s maintenance instructions. Use low-mineral water, such as distilled water, as recommended for your device, and keep steam vaporizers away from children because of burn risk. EPA: Humidifier Maintenance

Keep hydration advice personal

Ask your clinician how much fluid is right for you, particularly if you have been advised to limit fluids.

Rinse safely, if nasal irrigation is appropriate

Nasal irrigation can help flush mucus and irritants, but the water and equipment must be safe. Ask your clinician whether rinsing is appropriate, especially if your immune system is weakened or you are choosing a device for a child. FDA: Is Rinsing Your Sinuses With Neti Pots Safe?

Use store-bought distilled or sterile water. If using tap water, bring it to a rolling boil for 1 minute, or 3 minutes above 6,500 feet, then let it cool before use. Do not use untreated tap water.
Use a saline mixture and follow the device or packet instructions rather than improvising a recipe.
Wash and dry your hands, clean the device after use and allow it to dry between uses.
Contact a clinician if rinsing worsens symptoms or causes fever, headaches or nosebleeds.

See the FDA device-use guidance and CDC safe-water guidance for details. Seek medical attention right away for headache, fever, confusion or vomiting after sinus rinsing, as advised by CDC.

When symptoms need an evaluation

Contact a healthcare provider for severe headache or facial pain, symptoms that worsen after improving, symptoms lasting more than 10 days without improvement, fever lasting longer than 3 to 4 days, or repeated sinus infections. These are not the only reasons to seek care; have any severe or concerning symptom assessed. CDC: Sinus Infection Basics

Many sinus infections improve without antibiotics. Ask your clinician or pharmacist which medicines, if any, are appropriate rather than following a universal decongestant schedule. CDC: Sinus Infection Treatment
