Sinusitis

Sinus is a cavity with single opening. There are several sinuses in the bones of head, filled with air bony cavities with only one opening. Those above the nasal bridge are frontal sinuses, under the eyes and beside the nose are paranasal sinuses. The infection of the sinus is called as sinusitis. Sinusitis is presented by frequent nasal secretions, sneezing, pain, and sometimes fever.

Sinus infections are not contagious.  They arise mainly from viruses and bacteria  which contaminate a person whose sinuses support their proliferation because of minor, and rarely major abnormalities in the person's sinus tissue. For example swelling, inflamation, abnormal mucus production, etc. So, most people do not transmit sinus infections, leaving some exceptions behind.

Sinusitis is one of the more common conditions that can afflict people throughout their lives. Sinusitis commonly occurs when environmental pollens irritate the nasal passages, such as with hay fever. Sinusitis can also result from irritants, such as chemicals or the use and/or abuse of over-the-counter (OTC) nasal sprays, and illegal substances that may be snorted through the nose. 

Many people are affected by the sinusitis throughout their life. Based on recent research, it is found that 30 million adults have "sinusitis".

Symptoms

• Sinus headache
• Facial tenderness 
• Pressure or pain in the sinuses
• Fever 
• Cloudy discolored drainage
• Feeling of nasal stuffiness
• Sore throat, and cough.

Popular treatments and recommendations

• Carefully try over-the-counter treatments such as pain and fever medications (acetaminophen [Tylenol]), decongestants, and mucolytics.
• Some health physicians suggest that nasal irrigation or a sinus rinse solution will help relieve symptoms of sinus infections, even chronic sinusitis symptoms with a "Neti-Pot" or a sinus rinse kit (sometimes termed a nasal bidet).
• Make the body/head part warm by using hot drinks like black, green, herbal or decaffeinated, hot rice soup throughout the day. Drink enough so that your urine turns light in color. Those hot liquids help moisturise your mucous membranes, speeding up the movement of your cilia and thus washing mucus out of your sinuses more quickly.
• Travelers may carry tea bags with them and ask the flight attendant for hot water to make tea that prevents dry air on jet liners which is particularly rough for the sinuses. 
• Apply warm compresses to your face. Do it three times a day for five minutes each time. Soak a small towel in warm water, then place it over your face below and between the eyes - it will help increase the circulation in your sinuses, which will also help speed up the movement of your cilia.
• According to yoga practitioners, sniffing a saltwater solution rapidly in and out of the nose, at low pressure, may also work. Warning: Do not try this alone without supervision.
• Try to cover your nose with some scaff to prevent from dust while moving to dusty places.
• Keep your bed tidy before good night sleep to prevent inhalation of particles.

Prevention

Early treatment of allergic sinusitis may prevent secondary bacterial sinus infections.
