Well, through Cleo magazine, I got some useful ways to cool your home, they're very environmental friendly too!
1. Open all windows in the morning or evening to let the breeze in.
2. If closing windows during the day makes you feel suffocated, leave them open but block the sunlight by installing blinds or shades.
3. If you're not using air conds, you're likely to switch on ceiling fan, but this will only blow hot air throughout the house, so use a box fan instead, and place a box of ice in front so that it'll create cool breeze.
These are indeed pretty simple tricks we all can practise, they save money too! But I do hope that it rains soon =_=""
It's getting late now, off to bed soon, good night!
