In Traditional Chinese Medicine, good health is believed to be achieved by a balance between yin and yang. They represent two abstract and complementary aspects that every phenomenon in the universe can be divided into.
Yin Yang
moon sun
female male
inside outside
cold hot
downward upward
moist dry
Winter Summer
The concept of yin and yang is also applicable to the human body; for example, the upper part of the body and the back are assigned to yang, while the lower part of the body are believed to have the yin character.
Yang "perfers/likes" Yin and vice versa.
Belly=Yin(cold) Back=Yang(Hot/Warm)
We are likely to turns our back(yang) against freezing winds(cold/yin).
We perfer to cover our belly with a blanket or something when we sleep even in the summer. If you don't, I suggest you do, you will less likely to catch a cold.
Hands=Yang Feet=Yin
You see kids (or yourself) throwing snowballs with their bare hands in the winter, they have fun and enjoy it. But try to walk on snow with your bare feet, you can't last a minute.
Food has yin and yang too. Watermelons are yin(cold), they are good for summer. If the cold weather in winter is killing you, eat lamb. Lamb warms your stomach, it's very good for your stomach and keep you warm.
Dairy products are consider "bad" in Traditional Chinese Medicine, because they make your "Qi" stay in your lower body. IF you've been eating dairy products or drinking milk all your life, and you don't feel sick or anything from it, then keep eating them. The most important thing is, just because something is consider "bad", you don't eat it at all. Or something is consider "good" and you eat a lot of it. It's all about keep good balance.
