回复：天冷，开暖气，皮肤干，痒，痒就挠，挠得都出血了，有何妙方？谢谢！

The best way is to put on skin lotion immediately after the shower or bath. Apply as quick as possible out of shower, before the skin gets dry. So the lotion will lock the moist in the skin. the other tip is: apply good amount of lotion generously all over the body.

an air humidier in the bedroom helps a lot too.

drink plenty of water, including putting water by night stand at night, drink it if you wake up at night.

if you try those, it should help. scratching it is the last thing to do, it will damage the skin and cause more trouble.
