People spend most of their time indoors.But your home can be two to five times as polluted as the air quality can cause health problems.And a lot of these problems are caused by waht is in your house.
To make your home healthy,here are some useful tips:
Make sure your house is properly aired.Wetness causes mold(霉),especially in the bathroom.
Is the fan in your bathroom working well?Turn it on.Put a sheet of paper against it.If the paper sticks,the fan is strong enough.If not,it needs to be repaired.A good fan makes sure the air in the bathroom is fresh.
Keep your gutters(水槽) clean and clear,so that dirty water doesn't make your kitchen or bathroom smell bad.
And don't leave trash in bags or bins in your kitchen.The place for it is outside,waiting for collection.
When your are at home,open the window to let in fresh air.
Follow these simple steps and you're sure to notice an improvement.
