Top tips to beat a cold

Dr Chris Smith, the BBC's "naked scientist" from the department of pathology at Cambridge University, gives us his top tips for beating winter bugs at home, rather than the pharmacy.

Avoid getting one

Staying fit is the best way to avoid a cold. Healthy improves skin quality and mucous membrane growth, which are the first lines of defence against viral infection.

Getting out and about in lifts spirits by keeping your circadian rhythm (internal clock) on track and helping you sleep better.

If you've succumbed

Antibiotics won't work on cold viruses. Use paracetamol instead, a brilliant and safe drug. It works well to minimise symptoms, making you feel better and more able to function normally.

Gargling with salt water reduces throat inflammation. Hot drinks, such as water mixed with lemon and honey, can give relief.

Steam inhalations are recommended for immediate relief.

Get a large bowl filled with just-boiled water and put a couple of drops of menthol, eucalyptus or camomile in and breathe in the fumes.
