This idea is supported by earlier research showing that only children older than five make confused judgments about the order of sensations felt on their hands when they are crossed.
这种观点得到早期研究的支持，它表明的大于5岁的孩子，当他们抱臂时，会对他们手上的感觉的顺序判断感到困惑。
Practically, it's unlikely that this will result in significant pain relief for pain in areas other than the hands, and the ongoing duration of the relief is not known. However, the study adds to understanding of how the brain processes pain, which could help the development of new types of anesthetics.
实际上，抱臂不会减少除了手的其他部位的明显疼痛感，而且疼痛缓解的持续时间也不明确。然而，研究还了解了大脑如何对疼痛进行处理，帮助发明新的麻醉药。
And, perhaps it sheds light on the classic posture of adolescent defiance: standing with one's arms crossed, cursing. Both cursing and arm crossing could reduce emotional torment. After all, the "hurt" or "unpleasant" aspects of pain are processed by the same brain regions, whether the insult is psychological or comes from a physical injury or illness.
而且这可能阐明了青少年反抗的经典姿势：双手交叉站着，骂人。骂人和抱臂可以降低情感痛苦。毕竟，无论这种侮辱是心理的还是身体的受伤或疾病，“受伤”或“不愉快”方面的疼痛都是在同一个脑区进行处理的。
