I think all of you have heard of these notices going around, it is potentially harmful to your body so here are some ways to minimize it. Before that some information on where it is coming from. The dust originates from the deserts of Mongolia, northern China and Kazakhstan. They have very dense clouds with fine, dry soil particles and that carries over to China, North and South Korea and Japan, as well as parts of Russia. Only in the most recent years it has been getting a lot more serious.
If you have any repertory problems or any immunity problem it might be a good idea to refrain from going outside when the dust level is high and if you have to go out, wear a mask to keep the dust out. Washing your face and hands on a regular basis and drinking a lot of water is a good way keep the dust from effecting you.
