The Magic of Feng Shui!  

Having trouble sleeping? Well, feng shui may be the answer! Feng Shui is the Chinese practice of arranging a space to achieve harmony and balance. You can easily apply the principles of Feng Shui to a room and what’s more, you don’t need to spend a lot of money to do it! In your bedroom, you should paint your walls and ceiling in a soft pastel colour and keep the lighting dim. Your bed must be positioned so that neither your feet nor head are facing the door. Also, your room mustn’t be cluttered. This means that you have to get rid of the stereo, the TV, and any plants. Do all this and, according to the Chinese, you should attract good luck and prosperity, in addition to a good night’s sleep!
