【免疫力】整合式免疫力提升方案
在之前的文章中,我們已探討過即使完成新冠疫苗接種,持續強化免疫系統仍至關重要(詳見全文)。人體免疫功能的優劣取決於多項健康指標,從營養攝取到運動習慣皆涵蓋其中。要全面增強免疫防禦力,必須採取整合式的生活型態策略。
讓我們深入解析健康免疫系統的關鍵要素!

精神健康
心理健康狀態是整體健康(特別是免疫機能)的核心組成。統合分析顯示,患有抑鬱症、焦慮症、物質濫用和精神分裂症等心理疾病的新冠患者,其死亡率顯著較高[5]。即便未達臨床診斷標準,長期處於社交孤立、孤獨感或慢性壓力狀態,同樣會削弱免疫防禦力[6,7]。
現階段已有豐富的線上資源、專業書籍和行動應用程式可協助建立自我照護習慣,必要時亦可尋求專業心理諮詢服務。
改善睡眠
人生約三分之一時間用於睡眠,其對健康的重要性不言而喻。大量研究一致表明,每晚睡眠少於6小時會導致:T淋巴細胞數量減少、自然殺手細胞(NK)活性降低、端粒長度縮短、炎症標記物(C反應蛋白和IL-6)濃度上升。與每日睡7-8小時者相比,睡眠不足5小時者出現鼻塞和呼吸道感染的機率明顯增加[8]。
充足睡眠不僅能降低感染風險,更能優化疫苗接種後的免疫反應效果[9]。

營養管理
來自日常飲食或專業補充劑的關鍵營養素,為所有細胞(包含免疫系統)提供運作能量[10]。研究指出,以高品質植物性食物為主的飲食模式,與較低的新冠感染風險及疾病嚴重度密切相關[11]。
特別重要的免疫調節營養素包括:維他命A(3000-5000 IU)、維他命C(1000-2000 mg)、維他命D(2000 IU)、鋅(30 mg)。這些營養素能有效預防呼吸道感染、調控炎症反應,並支持白血球生成與功能[12-14]。在某些國家,靜脈注射維他命C已被納入住院新冠患者的標準治療方案,目前更有臨床試驗正在評估高劑量靜脈維他命C的治療潛力[15]。
若想進一步提升免疫防禦,可考慮補充強效抗氧化劑穀胱甘肽。研究顯示,穀胱甘肽缺乏可能是導致新冠重症和住院的獨立風險因子[16]。了解更多新冠相關營養資訊請點擊此處。
