【免疫力】整合式免疫力提升方案
在之前的文章中,我们已探讨过即使完成新冠疫苗接种,持续强化免疫系统仍至关重要(详见全文)。人体免疫功能的优劣取决于多项健康指标,从营养摄取到运动习惯皆涵盖其中。要全面增强免疫防御力,必须采取整合式的生活型态策略。
让我们深入解析健康免疫系统的关键要素!

精神健康
心理健康状态是整体健康(特别是免疫机能)的核心组成。统合分析显示,患有抑郁症、焦虑症、物质滥用和精神分裂症等心理疾病的新冠患者,其死亡率显著较高[5]。即便未达临床诊断标准,长期处于社交孤立、孤独感或慢性压力状态,同样会削弱免疫防御力[6,7]。
现阶段已有丰富的线上资源、专业书籍和行动应用程式可协助建立自我照护习惯,必要时亦可寻求专业心理咨询服务。
改善睡眠
人生约三分之一时间用于睡眠,其对健康的重要性不言而喻。大量研究一致表明,每晚睡眠少于6小时会导致:T淋巴细胞数量减少、自然杀手细胞(NK)活性降低、端粒长度缩短、炎症标记物(C反应蛋白和IL-6)浓度上升。与每日睡7-8小时者相比,睡眠不足5小时者出现鼻塞和呼吸道感染的机率明显增加[8]。
充足睡眠不仅能降低感染风险,更能优化疫苗接种后的免疫反应效果[9]。

营养管理
来自日常饮食或专业补充剂的关键营养素,为所有细胞(包含免疫系统)提供运作能量[10]。研究指出,以高品质植物性食物为主的饮食模式,与较低的新冠感染风险及疾病严重度密切相关[11]。
特别重要的免疫调节营养素包括:维他命A(3000-5000 IU)、维他命C(1000-2000 mg)、维他命D(2000 IU)、锌(30 mg)。这些营养素能有效预防呼吸道感染、调控炎症反应,并支持白血球生成与功能[12-14]。在某些国家,静脉注射维他命C已被纳入住院新冠患者的标准治疗方案,目前更有临床试验正在评估高剂量静脉维他命C的治疗潜力[15]。
若想进一步提升免疫防御,可考虑补充强效抗氧化剂谷胱甘肽。研究显示,谷胱甘肽缺乏可能是导致新冠重症和住院的独立风险因子[16]。了解更多新冠相关营养资讯请点击此处。
