Hot houses bad for health

High temperatures are not healthy

Householders who turn up their central heating to keep out the cold could be risking their health, researchers say.

They claim raising the temperature too high can lead to the spread of germs, skin problems, poor concentration and lethargy.

A study of 1,800 people, carried out by the University of East Anglia, found most people would rather make their homes warmer than puton extra clothes.

A 2000 government survey said that, on average, house temperatures had risen five degrees centigrade over 30 years.

The temperature in the average home in England is now 18 degrees centigrade.

The report, paid for by energy company Powergen, claims better heating systems, more insulation and cheaper gas and electricity prices are among the reasons for the rise.

Many effects

Dr Sarah Brewer, a GP and health writer, said: "A hotter home can have an effect on the condition of your skin.

"Studies have shown that even short periods of exposure to low air humidity can increase roughness and exacerbate skin problems, such as atopic eczema.

"It's not just the skin that can be affected - the body is also sensitive to temperatures that are too warm.

"During the day, if heating is set too high, it can induce lethargy, poor concentration and fatigue.

"At night, a room that is too hot can mean a disturbed night's sleep."
