Freeze a handkerchief（手帕）and put it on your neck, forehead, arms or legs.     38     When the handkerchief heats up, simply wet it and put it back in the fridge. You can also put an icepack behind your head.

Run cold water over your wrists（手腕）. Wet your wrists and other parts, such as your neck and your inner elbows, with cool water for 10 seconds each. This will lower your temperature for a little bit.     39     This can be especially helpful for cooling down right before you go to bed.

Fill your bathtub（浴缸）with cool water and get in. Once you are used to the temperature, let some water and refill it with cold water. Keep doing this until you feel cool enough.     40
