Catch a cold and the pharmacy shelves promise the world: remedies to fight it, beat it, knock it on the head. Most of them do very little, and we collectively spend a fortune on the hope that they do. A cold is a virus that runs its course, and the honest truth is that nothing cures it. But some things genuinely help you feel better.
What does not really work
A great many products lean on ingredients with weak or no evidence. The expensive immune-boosting supplements rushed out at the first sniffle largely do not shorten a cold. Antibiotics do nothing at all against a virus and should never be sought for one. Much of the cold-and-flu aisle is selling reassurance at a premium.
What actually helps
The useful steps are cheap and mostly already in your house.
- Rest, which is what your body needs to fight it
- Fluids, to stay hydrated and ease a sore throat
- Simple paracetamol or ibuprofen for aches and fever
- Honey in warm water, which genuinely soothes a cough
- Steam from a hot shower or bowl to ease a blocked nose
The sensible line
Treat the symptoms cheaply, rest as much as you can, and let time do the actual work. Most colds clear within a week or so. Save your money, skip the miracle remedies, and see a doctor only if things are severe, drag on far too long, or you are in an at-risk group. The pharmacy cannot cure a cold. It can only sell you a more comfortable wait.
