Temperature.

Here, Dr. Porter examines what happens to our health when our body temperature strays from the norm. Infections can cause fevers, particularly in children, but does the use of paracetamol and other such drugs actually prolong an infection? Other conditions cause changes in temperature such as Raynaud's disease - we hear about the latest treatments for this from the Royal Free Hospital in London. We also hear about hypothermia, particularly amongst the elderly, and look at ways to recognise the signs of it and how to treat it.
