Why Sinus Issues Are Worse in Dry Air
If you wake up with a dry nose, sinus pressure, or post-nasal drip, your indoor air might be the problem—not just allergies or a cold.
Dry air causes:
- Nasal passages to dry out and swell
- Mucus to thicken, leading to congestion
- Increased irritation in the throat and sinuses
- Worsened sleep and frequent headaches
The best solution? A reliable humidifier for sinus problems that adds soothing moisture to your indoor air, especially while you sleep.
How a Humidifier Helps Sinus Relief
When you maintain healthy indoor humidity levels (between 40–60% RH), you:
- Keep sinuses moist and reduce inflammation
- Improve mucus drainage and reduce congestion
- Soothe dry or cracked nasal membranes
- Sleep better and breathe more easily
Humidifiers are a natural, drug-free way to support your respiratory health—especially helpful for people with seasonal allergies, chronic sinusitis, or dry indoor heat.
