To treat sinusitis at home, buy over-the-counter saline sprays or nose drops, or create a saline solution by using distilled water or boiling hot water and letting it cool, recommends WebMD. Press a gel pack or hot, moist towel to your face for up to 10 minutes a few times daily. Alternatively, inhale warm air from a sink with hot water, a steamy shower or a hot tub.
Drink lots of water to maintain thin mucus, and stay away from environments with overly cool, dry air, suggests WebMD. Use a humidifier to keep an indoor environment with adequate moisture in the air. Place a vaporizer nearby, and inhale the mist instead of the steam. Clean the device regularly to prevent the growth of bacteria. If you have postnasal drip, try gargling with warm salt water to prevent a sore throat; however, this home remedy is not advisable for children ages 8 and below.
When blowing your nose, be gentle, and avoid blowing forcefully to avoid pushing thick mucus into the sinuses, notes WebMD. Minimize consumption of alcoholic beverages, as alcohol causes the tissue that lines the nose and sinuses to become swollen. Ventilate your home by opening windows on a warm day to clear indoor air. Over-the-counter medications may help alleviate sinusitis symptoms such as pain and a clogged nose.
