Everyday health hazard 4： 4 Withdrawing money from ATM machines is a common habit for most of us. However，cleanliness tests in Britain have revealed that cash machines are just as dirty as public toilets，and many of us are failing to wash our hands after using them.Experts assessed swabs(药棉棒) from the key pads on cash machines and also from nearby public toilets and found that they both contained the same types of bacteria known to cause sickness.To look after your health，use an antibacterial hand gel once you have made your withdrawal and after handling money.
Everyday health hazard 3： 3 Need an excuse to put your feet up? Well, good news: research suggests that leaving the housework for another day could give your health a boost! Research results published in the Journal of Family Psychology revealed that doing housework when you get home from work prevents levels of cortisol (the stress hormone) from lowering and reduces recovery from stress.

Everyday health hazard 5： 5 Find yourself frequently cancelling plans and bailing out on social events to have a bit of time to yourself? Then it may be time to pay some attention to your social life.While a bit of “me time” is essential to good mental and physical health，too much time on your own can actually be bad for you. Research suggests that having strong social bonds promotes brain health， reduces feelings of depression and stress and encourages you to look after your health.In fact，a study found that having few friends affects your longevity as much as smoking 15 cigarettes a day.
According to a study by the University of Arizona，your work station contains nearly 400 times more germs than the average toilet seat，making it a less than ideal place for dining.
