If you have a slight fever, or even just a cold, you could be risking serious heart problems if you go to work, say researchers in a news study. A study looked at 10,000 Whitehall employees (UK civil servants) over a ten-year-period. The study was carried out by researchers at University College, London.

The researchers found that even if you just have a common cold you could be putting your heart under great strain - so much, in fact, that the situation could lead to the onset of coronary heart disease.

According to team leader, Prof. Sir Michael Marmot, \"Among 30 to 40 per cent of the population, we have found that those who were unwell but took no absence at all from work had double the incidence of coronary heart disease over the following years.\"

The researchers said that a great many people continue going to work when they are unwell. They said most people are completely unaware of the risks they are taking.
vProf. Sir Michael Marmot said people think they are doing good, when in fact, they are increasing their risk of an early death.
