8. Think cool.
心静自然凉
Read books about climbing Mount Everest, visiting Norway, or watch "Ice Age", or "The Day After Tomorrow". You might not be physically cooler, but if your mind envisions a cold environment, you might feel a bit cooler.
去读读关于登珠峰、游挪威的书，看看《冰河世纪》、《后天》这样的电影。这样也许身体不会感到凉快，但是因为大脑在联想凉爽的事物，所以你也许会感觉到少许凉意吧。
