Untidy beds may keep us healthy
Failing to make your bed in the morning may actually help keep you healthy, scientists believe.
Research suggests that while an unmade bed may look scruffy it is also unappealing to house dust mites thought to cause asthma and other allergies.
A Kingston University study discovered the bugs cannot survive in the warm, dry conditions found in an unmade bed.
The average bed could be home to up to 1.5 million house dust mites.
The bugs, which are less than a millimetre long, feed on scales of human skin and produce allergens which are easily inhaled during sleep.
The warm, damp conditions created in an occupied bed are ideal for the creatures, but they are less likely to thrive when moisture is in shorter supply.
'Small glands'
The scientists developed a computer model to track how changes in the home can reduce numbers of dust mites in beds.
Something as simple as leaving a bed unmade during the day can remove moisture from the sheets and mattress so the mites will dehydrate and eventually die

Researcher Dr Stephen Pretlove said: "We know that mites can only survive by taking in water from the atmosphere using small glands on the outside of their body.
"Something as simple as leaving a bed unmade during the day can remove moisture from the sheets and mattress so the mites will dehydrate and eventually die."
In the next stage of their research, the scientists are putting mite pockets into beds in 36 houses around the United Kingdom to test their computer model and will investigate how people's daily routines affect mite populations.
Building features such as heating, ventilation and insulation will also be altered to monitor how the mites cope.
Dr Pretlove said the research had the potential to reduce the
