   • 剪短指甲能避免你抓伤皮肤。^[3]
   • 考虑在晚上和睡觉的时候戴手套，避免自己抓挠皮肤。^[4]

   • 每天至少涂一次保湿霜。最好是在沐浴或泡澡后，趁皮肤还有点湿的时候涂保湿霜。^[6] 沐浴之后和临睡前，将保湿霜着重涂抹在最痒的部位。^[7]
   • 使用不会刺激皮肤的无味无色保湿霜。^[8]
   • 在房间放一台加湿器，保持空气湿润，确保睡觉的时候皮肤不会干燥和发痒。^[9]
   • 避免会令皮肤干燥的极端温度。

   • 在水里撒一些小苏打、未煮过的燕麦或胶状燕麦。这些成分均能舒缓皮肤。^[11]
   • 只能泡10到15分钟。在水里泡太久的话，皮肤会变得干燥，反而更加痒。
   • 使用微温的水，不要使用热水。热水会让皮肤失去的天然油脂，使它变得更干燥更痒。
   • 泡澡后在皮肤上涂一些乳液，着重涂抹手脚，然后才彻底擦干皮肤。这么做能锁住皮肤水分，保持皮肤湿润，让它不容易发痒。

   • 你可以断断续续地冷敷皮肤10到15分钟，或直到自己睡着为止。^[13]
   • 如果你没有冰袋，使用一袋冷冻蔬菜也能达到相同的效果。
   • 不要直接把冰块放在皮肤上。一定要先用布裹着冰块或冰袋。冰块在皮肤上敷太久可能会冻伤皮肤。

   • 穿凉爽、宽松和质地光滑的棉质或美利奴羊毛睡衣，防止自己抓痒和过度出汗。^[14]
   • 棉质衣服是很好的选择，它们不但透气，摸起来也很柔软。^[15]
   • 考虑穿戴袜子和手套，阻止自己抓挠皮肤。

   • 将卧室的温度设置在15到24摄氏度，这是最佳睡眠温度。^[17]
   • 打开风扇或窗口，以保持空气流通。^[18]
   • 使用天然纤维制成的舒适床单，比如棉质床单。^[19]

   • 发红
   • 肿胀
   • 疼痛和（或）一摸就痛
   • 皮肤摸起来温热
   • 发烧
   • 有红斑、微微凹陷的小坑和（或）水疱

   • 戴上棉等天然纤维制成的手套，防止双手发痒。

   • 手脚发痒可能是过敏原、食物过敏、化妆品、环境因素、蚊虫叮咬、刺激性大的肥皂或洗涤剂造成的。^[25]
   • 如果你有穿戴首饰，手脚发痒也可能是皮肤对金属过敏造成的。^[26]
   • 要是你怀疑皮肤发痒是某种物质造成的，试着减少接触它，看看症状是否有所改善。^[27]

   • 尽量每天至少喝2000到3000毫升水。如果只喝水很无聊，不妨加点果汁提味。
   • 你也可以吃含水量高的食物，比如黄瓜、樱桃、番茄、芹菜、青椒、西瓜、草莓、哈密瓜和西兰花。^[28]

   • 在光照治疗中，皮肤会接受一定量的自然光，或人造长波紫外线（UVA）和窄谱中波紫外线（UVB）照射。这项治疗可以单独进行，也可以与药物配合使用。^[50]
   • 光照会增加皮肤过早衰老和罹患皮肤癌的风险。^[51]

小提示

• 向皮肤科医生咨询皮肤瘙痒的问题。最好的治疗方法是弄清楚皮肤发痒的原因，然后对症下药。
