Vitamin C might shorten a cold by about half a day. That’s it. And that’s if you take it consistently before getting sick, not just after you’re already sneezing into your sleeve.
Zinc lozenges? There’s some evidence they can help, but only if you take them within 24 hours of your first symptoms. Wait too long? It’s a no-go. Also, nausea, metallic taste and stomach cramps can be side effects.
Antibiotics don’t treat viruses. That cold, that flu—those are viruses, and using antibiotics when you don’t need them contributes to antibiotic resistance. That’s a big deal.
So here’s what actually helps when you’re sick with a viral illness like the cold or flu.
Neti pots can be helpful for congestion if you use them safely. That means using sterile or distilled water. Tap water can harbor dangerous organisms, especially for your sinuses.
Drinking fluids helps thin your mucus, which can also ease congestion. And staying hydrated just helps your body work better.
Acetaminophen or ibuprofen can help with fevers, headaches and body aches. Honey can soothe a cough or sore throat in kids over the age of one. Last, but certainly not least, rest is crucial for your immune system to function properly.
Just remember: not everything that sounds “natural” is safe. And not everything in a bottle actually helps. So when in doubt, ask your doctor.
