研究表明：缺少友誼破壞免疫力
研究表明，社交生活越少，大腦里會有越多焦慮引起的化學物質，人就越可能生病。一項對276個18到55歲的成人研究表明，有6個以上朋友的人比更少朋友的人抗擊感冒的能力強4倍。對策：如果太忙不能打電話，就在晚上給你的朋友發一條手機短信吧。 研究人員發現與大笑有關的情緒可以降低壓力激素，增加某些免疫細胞并且激活其他的免疫細胞。極端的壓力可以導致天然殺手細胞的減少，殺手T細胞活力降低，以及能增強免疫系統反應能力的巨噬細胞含量的減少。減輕壓力則出現血壓、心率以及白血球數量的增加等類似適度運動后的良好征兆。建議不要把困擾自己的問題悶在心里，積極討論會更好。(張明) [責任編輯： 李然 ]
