凌晨5点闹钟响了，你昨晚加班到12点，真正睡着估计都快1点了。         Coffin chamber M13 Photo: Courtesy of the Shanxi Provincial Institute of ArchaeologyThe highest-ranking noble cemetery complex from the late Xia Dynasty (c.2070BC-c.1600BC) ever discovered has been unearthed at the Zhongcun site in North China's Shanxi Province, expanding research on Xia and Shang (c.1600BC-1046BC) civilizations and early state formation in ancient China, according to a press release that the local institute of archaeology sent to the Global Times on Monday.
Located on a hilly terrace west of the Taihang Mountains and flanked by the Songxi River, the site was excavated in 2024 and 2025 by the Shanxi Provincial Institute of Archaeology and partner institutions, leading to the discovery of 18 tombs, including six Xia Dynasty burial sites and 12 Warring States Period (475BC-221BC) graves. 
"These are the highest-ranking Xia aristocratic tombs discovered so far, indicating that this location was a regional center," the institute said.
The Xia Dynasty is traditionally regarded as China's first hereditary dynasty, though contemporaneous written records are lacking.
The well-organized Xia tombs, concentrated in the western part of the cemetery, feature uniform east-west oriented vertical earthen pits. Researchers recovered nearly 40 sets of artifacts with distinctive local cultural characteristics, including pottery, lacquerware and turquoise ornaments. 
Extended regional surveys across the Songxi River valley yielded more than 10 Xia and Shang period sites. Test excavations at nearby relic sites unearthed pottery fragments, stone tools, bronze knives, as well as tin-bronze ingots and smelting residue, providing solid evidence of early metal mining and craftsmanship. 
Local copper-iron symbiotic ore deposits confirm exploitation of these resources during the Xia and Shang eras, while typical cultural artifacts found in adjacent counties reveal widespread regional cultural exchange.
Multidisciplinary analyses further decoded the civilization's features. Ancient human remains belong primarily to the ancient population of the Central Plains with minor Mongolian Plateau ­genetic traits, forming a stable patrilineal clan. The community relied on millet farming and maintained long-distance resource trade networks. 
Artifact provenance tests trace scallop shell ornaments to the Bohai Sea, cinnabar to Hunan-Guizhou ore belts, turquoise to the eastern Qinling Mountains area, and coffin timber to local Taihang pine trees. Such diverse materials reflect close interaction among the Taihang foothills, the press release noted.
Lab restoration unveiled refined ritual relics, including a dragon-patterned lacquer cylinder with red and black stripes and an intact lacquer gu vessel (a type of wine vessel). Turquoise plaques from the site match specimens from the Erlitou site, a core Xia cultural relic, proving ­cross-regional cultural interaction. Radiocarbon dating places the site's active period between 1880BC and 1450BC, aligning with the late Xia Dynasty.
Scholars confirmed the findings have helped reshape academic understanding of Xia-Shang civilizations and reconstruct multi-level settlement patterns on the western Taihang foothills, while offering new insights into social complexity and civilization development in early China.

二 | 研究还显示，那些长期睡不好的跑友，一年内遭遇伤病的概率高达68%。负责这项研究的教授表示：“睡眠是预防受伤的关键因素，但大多数跑友根本没把它当回事。

三 | ”为什么缺觉跑步更容易伤？可能有人会说："我不就是睡得少点嘛，顶多跑起来累一点，至于受伤吗？"这背后有三个原因。第一、你的肌肉，根本没来得及修复。跑步的时候，肌肉纤维会有微小的撕裂，这是正常的。

四 | 身体修复这些撕裂，主要靠睡觉的时候分泌的生长激素。如果睡眠不足，身体无法完成修复，损伤确实会像滚雪球一样累积，攒着攒着就出大事了。第二、你的跑姿悄悄变形了，自己根本不知道。科学家发现，只要一个晚上没睡好，第二天跑步的姿态就会发生变化——步幅、落地方式、身体稳定性都不一样了。缺觉的时候，你的核心没劲了，腿脚发软，落地也变重了。 更可怕的是，你自己完全感觉不到这些变化。你以为还是平时的跑姿，实际上已经歪七扭八了，关节和韧带承受的压力大大增加。第三、你的反应变慢了，身体报警你也听不见。

五 | 缺觉的人注意力不集中、反应迟钝，这大家都懂。放在跑步上，问题就大了——明明膝盖已经开始酸了，你因为疲劳没察觉到；明明地上有个小坑，你因为走神没看见。身体的早期报警信号被你错过了，小伤就容易拖成了大伤。给跑友的3个实在建议很多跑友特别在意跑量、配速、装备，唯独把睡觉排在最后一位。更关键的是，经常运动的人其实比普通人需要更多睡眠才能充分恢复。你以为睡7个小时够了，你的身体可能需要更长时间。建议一：把睡觉当成训练的一部分。

六 | 别再把睡觉当成"可有可无"的事了。

七 | 你要这么想：今天你跑了10公里，完成了一次训练；今晚你睡够8小时，完成了一次"修复训练"。两者一样重要。建议二：没睡好，就别硬撑。如果前一晚只睡了四五个小时，第二天早上就别硬撑着去跑原定计划了。改成慢跑、拉伸，或者干脆多睡一会儿。多睡两小时，比硬跑10公里更有价值。

八 | 建议三：固定作息，少熬夜刷手机。

九 | 尽量每天差不多时间睡、差不多时间起；睡前少看手机；少喝咖啡浓茶；卧室暗一点、凉一点。白天如果实在困，中午眯个20分钟也好。写在最后下次5点闹钟又响了，你发现昨晚又只睡了4个小时——请对自己说一句：今天，我的任务是睡觉，不是跑步。

十 | 跑步是为了提高生活质量，为了享受生活，而不是为了透支身体去换一张打卡截图。真正能跑得久的人，不是最能吃苦的，而是最懂休息的。亲爱的跑友，你以前有没有在缺觉的情况下硬跑过？欢迎在评论区聊聊。
