Sinus congestion can be managed with various home remedies. Here are some tips from the search results:

• Drink lots of fluids, such as water or juice. This will help dilute mucous secretions and promote drainage. Avoid beverages that contain caffeine or alcohol, as they can be dehydrating.
• Use a nasal saline spray. It’s salt water, and it will help keep your nasal passages from drying out.
• Try a neti pot, nasal irrigator, or bulb syringe. Use distilled, sterile water or water that’s been boiled and cooled to make the irrigation solution. Rinse the irrigation device after each use and let it air dry.
• Use a bioelectronic sinus device. The device is placed on the face and uses microcurrents to stimulate nerves and help reduce pain and congestion.
• Place a warm, wet towel on your face. It may relieve discomfort and open your nasal passages.
• Prop yourself up. At night, lie on a couple of pillows. Keeping your head elevated may make breathing more comfortable.
• Inhale steam from a pot of warm (but not too hot) water or take long showers. Breathing in steam can help keep the mucous membranes moist.
• Use a humidifier or vaporizer. These can provide a consistent stream of moisture into the air that could help clear your sinuses. This is especially helpful if your congestion is affecting your sleep schedule.
• Eat spicy foods like peppers or hot mustard. Some people find that spicy foods help open up their nasal passages and relieve some of the sinus pain and pressure.
• Apply warm compresses to your face for about 15 minutes to help treat nasal or sinus congestion.
• Use eucalyptus oil. It may relieve the symptoms of sinus congestion and help kill germs in and around the nasal passage that contribute to a sinus.
• Use over-the-counter treatments such as nasal spray, saline nasal spray, and pain relievers.

It is important to note that if your sinus congestion persists or is accompanied by other symptoms such as fever, headache, or toothache, you should see a doctor.
