在水中加入少量漂白剂有助于减轻慢性湿疹(特应性皮炎)的症状。
湿疹是一种皮肤瘙痒疾病,通常会因细菌感染而恶化。湿疹漂白浴可杀死皮肤表层的细菌,从而减少瘙痒、发红和脱屑。结合其他湿疹治疗方案,如药物和保湿霜时将更有效果。
如正确稀释并按照指示使用,漂白剂浴对儿童和成人是安全的。为了获得最佳效果:
- 将 1/4 杯(约 59 毫升)至 1/2 杯(约 118 毫升)漂白剂倒入 40 加仑的装满热水的(约 151 升)浴缸中。计量标准为美国标准尺寸浴缸加满至溢流排水孔。请使用家用漂白剂,并阅读产品标签。美国环境保护署表示,在美国,漂白剂产品可能含有 6% 至 8.25% 的次氯酸钠。如果次氯酸钠的浓度在该范围的上限,则使用少于 1/2 杯的漂白剂。
- 颈部以下在热水中浸泡 10 分钟;或只浸泡受累皮肤区域。
- 如果您的皮肤不适应漂白浴,请冲洗。用毛巾轻轻拍干。
- 立即涂抹大量保湿霜。
- 每周进行不超过三次的漂白浴。
如果使用过多的漂白剂或漂白浴太频繁,您可能会出现皮肤干燥。如果您的皮肤出现皲裂或非常干燥,任何沐浴,包括漂白浴,都可能会让您感到疼痛。在尝试湿疹漂白浴之前,先咨询医生。
