Frequently Asked Immune Support Questions

What are the best ways to prevent colds?

Colds are caused by viruses, so the best way to prevent a cold is to prevent infection with a cold-causing virus. Wash your hands often with soap and water for 20 seconds. If you have kids or are around kids a lot, help them wash their hands often, too. Make a conscious effort to avoid touching your eyes, nose and mouth. Do your best to stay away from people who are sick. If you have a cold, stay home and minimize exposure to others to avoid giving them a cold.

How do you recover from colds quickly?

Colds generally run their course in a few days. There is no cure for a common cold, but evidence suggests that zinc lozenges may help reduce the duration of a cold. Drink plenty of fluids to stay hydrated, and consider hot tea, which may help soothe a sore throat. Keep in mind that painkillers like ibuprofen and acetaminophen (Tylenol) will not make your cold go away faster, they only provide temporary relief of symptoms. You should not take antibiotics for a common cold unless directed by a qualified healthcare provider. Antibiotics work against bacteria, but colds are usually caused by viruses. If you have symptoms that seem particularly severe, or if you don’t feel better after 10 days, see your doctor.

How do you prevent catching a cold from someone?

Do your best to avoid exposure to people with colds. If you can’t avoid being in proximity to someone who has a cold, wash your hands often and encourage them to do the same if appropriate. If you can’t always access a sink, use an alcohol-based hand sanitizer often. Don’t touch your eyes, mouth or nose.
