Last night, I was watching a TV program about colds and influenza (the flu). A doctor on the program said that it’s easy to get sick in winter because of the cold weather and because it’s dry. He said that there are little hairs inside our noses. These hairs move fast in warm weather and keep viruses from getting into our bodies, but they need to be wet. Winters in Japan are dry, and air conditioners make the air even drier. We should drink a little water every hour. When we sleep, we can use a mask with a little water and mint oil on it to stop dryness. I think I’ll try to do both. (by Prof. Douglas Jarrell)
