You've probably noticed you're more likely to catch a cold if you pull a lot of all-nighters. But lack of sleep can also compromise your immune system's response to vaccines. And in some cases, make the shots useless. So says a study in the journal Sleep.
你可能会意识到这种情况:如果你经常熬夜的话,会更容易患上感冒。睡眠不足会损害免疫系统对疫苗的反应。而且在某些情况下,使打针失去应有的效果。上述研究发表在《睡眠》期刊。

Researchers gave 125 healthy, middle-aged men and women the Hepatitis B vaccine—a three-part vaccine given at one, two and six months. And during that time, volunteers tracked their sleep habits.
研究人员让125名中年男女注射了乙肝疫苗,这种疫苗全程共接种3针,按照1,2,6个月程序。在此期间,让志愿者们记录自己的睡眠习惯。

Six months after the final booster, researchers took blood samples to see if the patients had rallied sufficient numbers of antibodies against Hep-B. Eighteen patients had not—the vaccine had failed. Turns out the vaccine was almost 12 times as likely to fail in volunteers who regularly slept fewer than six hours a night compared to those who snoozed more than seven.
打完最后一针疫苗的六个月后,研究人员采集血液样本,看病人是否有足够数量的抗体来对抗乙肝。18名病人没有足够数量的抗体,免疫失败。事实证明,与那些酣睡7个多小时的病人相比,睡眠时间长期少于6小时的病人免疫失败的概率是前者的12倍。

Makes sense, because previous studies have shown that sleep deprivation cuts numbers of B and T cells—which coordinate the immune system's attack on bad guys. So remember, vaccines aren't magic. You still need a good night's sleep to give 'em a fair shot.
这在情理之中,因为之前的研究证明睡眠不足会减少B细胞和T细胞的数量,而这些细胞与免疫系统合作共同抵御疾病入侵。因此记住,疫苗不是万能的。你仍然需要高质量的睡眠,好给疫苗一次公平的机会。
