9. Make sure your environment is not too dry. Keep the air moist enough so that your nasal passages do not dry out. Consider using a humidifier.
8. Be careful with items such as money, pens, and keypads in public places. They are all potential sources of infection.
7. Take precaution when flying on commercial airlines. The recirculation systems aboard planes has been implicated in the spread of airborne infectious diseases
6. Garlic nose drops have been known to kill the viruses that cause colds (if you don't mind the smell of garlic!). In his book The Healing Power of Garlic Paul Bergner suggests crushing some garlic to obtain juice, adding ten parts water and mixing well.
5. If someone in your household is sick, let them use separate items, such as handtowels, from those who are healthy.
4. Keep your feet warm. Cold feet cannot cause a viral infection, but they can undermine your defenses thereby opening the door to them.
3. Keep your nasal passages clear and breathe through your nose. Your nose is able to filter out airborne dust and germs.
2. Alternative medications. Recent studies have shown that alternative medications such as zinc and Echinacea may help prevent the onset of colds.
1. Never put your hands in your eyes or to your nose without washing them first
such acetominophen (tylenol) aspirin, ibuprophen (advil), and naproxyn
sodium (naprosyn) are useful for reducing the pain and fever associated
with the common cold.
Decongestants such as pseudoephedrine hydrochloride (Sudafed) decrease nasal secretions and congestion.
Expectorants such as guaifenesin (Robitussin) thin respiratory secretions, make coughs more productive and decrease overall coughing.
Antitussives are opiate derivatives, such as codeine and dextromethorphan hydrobromide (Robitussin DM) that are useful in suppressing coughing by depressing the nervous system.
Antihistimines such as chlorpheniramine maleate (Chlor-Trimeton), brompheniramine maleate (Dimetapp), Dipheniramine hydrochloride (Benadryl), and triprolidine hydrochloride (Actifed) have been used to treat symptoms, but their efficacy in treating the common cold has been questioned since their primary mode of action is on the histamine allergic response of the immune system.
Human Rhinovirus have been recently developed for the treatment of the
common cold. The mechanisms of these drugs include antiviral binding to
rhinovirus, blocking the protein canyon binding site and using monoclonal
antibodies to the antireceptor, ICAM-1.
Hormonal methods such as Bradykinin inhibitors are also being explored.
Zinc lozenges have been
shown to reduce the duration of the common cold. Zinc deficiency has been
linked to a variety of immune system abnormalities.
Echinacea is a daisy like purple wild flower found across the United States. It has been shown to stimulate white blood cell activity.
Garlic has also been shown to have prophylactic activity (see prevention section)
While antioxidants such as vitamin C have been used for treating and preventing colds, it is unlikely that taking large doses will have significant effects on the majority of the Western population, which is without vitamin deficiency.
Menthol and Eucalyptus oils can provide relief from nasal congestion by causing a cool sensation in the nose. Local anaesthetic action also helps relieves sore throat and coughs. These oils also have antimicrobial activity that may help to inhibit infection of the upper respiratory tract.
While have been developed the practicality of immunizing large numbers of individuals against the common cold is minimal, primarily because so many different viruses have been implicated in causing colds. Additionally, developing an effective vaccine is difficult because upper respiratory infections are superficial, meaning the virus is not found in the blood, the site of the immune response.
Furthermore, most colds are self limiting. Left alone, most will
disappear within a few days and cause little harm to the host.
Temporary symptomatic relief, therefore, is often the most practical
