How Supplements Can Help with Fever and the Flu

fever and flu supplementsMillions of people suffer from colds and flu each year, which often leads to school and work absences, and sometimes, even serious complications. Research shows that more and more people are turning to health supplements to prevent and treat these viral infections, which are often associated with fever and other symptoms.  Since over-the-counter medications are often of little help in reducing the symptoms of colds and flu, people are relying on natural remedies, including health supplements to improve their health. Believing that natural remedies are more effective in boosting immunity and preventing colds and flu, people have spent billions of dollars on health supplements in the last year, which is more than twice what they spent on over-the-counter medications.

The Flu

The flu (influenza) is an upper respiratory tract infection caused by H. influenza virus. It is usually transmitted through direct contact (kissing, shaking hands with an infected person) or by coughing, sneezing, or talking. People usually feel sick a couple of days after exposure to the virus.

Symptoms of the flu includes high fever, abrupt onset of headaches, muscle aches, and fatigue. Runny nose, sore throat, and cough are common. Children may also experience vomiting and diarrhea, and develop ear infections as well. These symptoms may resolve after four to five days, but other people may feel ill for more than two weeks. With a weakened resistance, other people have severe symptoms and complication may arise.

Fever and flu can make children miss school and adults be absent from work. They may also spread the germs by just talking, coughing, sneezing, or touching common objects such as doorknobs and telephones, causing many others to be sick, too. To avoid these, many look for ways to shorten the duration of their illness and relieve their symptoms. Many over-the-counter medications are available, including antipyretics for fever, such as aspirin and acetaminophen, nasal decongestants, cough medications, and other drugs. However, their effects are often short-lasting and not enough to make one feel well enough to function at work or school.
