Your Bacterial Body


Helen Scales

Chris Smith

Come with us on a tour of your body to discover how the bacteria that live on and in you play an important role!  Bad breath bacteria, good gut bugs and the ones that escape through the other end all make an appearance, as we find out how bacteria are essential to your health and how probiotics could prevent or even treat asthma and allergies.  Plus, we find out how clot busting drugs could treat brain haemorrhages, why pilot whales are the cheetahs of the sea and how a robot could give you a full head of hair.  Plus, in a smelly kitchen science we ask if coughs and sneezes can spread diseases, then what about flatulence?

Questions

Can you keep your eyes open when you sneeze and if you do, will they pop out?


 

I have heard the when people sneeze it travels out of around 100ks per hour. Some people hold their sneeze in by either closing the mouth and nose or it just doesn't get let out. My question: Can this cause a brain aneurysm or any harm to the body when the sneeze is stopped in this manner.


They say there’s something called fight bite which happens when people get bitten by other people. They get a bad infection. What’s that all about?


I’d heard in the past that oral bacteria can cause heart valve problems and hip joint infections. Is this true and which bacteria are involved?


The new toothbrushes that I’ve seen adverts for on the TV have got a sort of scraper that you’re supposed to scrape along your tongue. Should we be using these things? Are they actually beneficial?


Is there anything you can do to combat bad breath apart from a tongue scrape and a toothbrush?


I read somewhere that gut bacteria makes some of our vitamins for us.


Are we washing off our skin bacteria using antibacterial soap? Can we put them back perhaps with some sort of lime yoghurt?
