上述普内科医生表示，若要缓解该症状，应在车上避免长时间看手机、书或电脑，减少头部晃动，同时避免过度后仰，可使用颈枕支撑颈 部。他还建议选择透气性好的口罩，避免密闭空间二氧化碳浓度过高。此外，可使用便携式喷雾瓶轻喷水雾，或用冷毛巾敷额头减轻头 晕。 界面新闻注意到，近几年，社交平台上一直存在"一上高铁就犯困"的相关讨论和测试视频。去年6月，据中新经纬报道，一位12306客服表 示，高铁车厢虽然是密闭空间，但在行驶过程中中央空调在保持恒温的前提下会实时更换空气，提供氧气，即便是长时间行驶乘客也不会 出现缺氧的情况。但也有客服称，每趟列车在出发以及到站后都会做系统检查，空气方面肯定是没有问题的。至于有乘客检测二氧化碳浓 度变高可能确实是因为乘客密度变高。 不过，有评论指出，由于视频拍摄者多采用自购仪器检测，其检测环境和设备精准度存在诸多影响条件，少数样本尚不能代表所有高铁的 空气情况。除二氧化碳影响外，0.5-2Hz的低频振动、50-60分贝白噪音及恒温环境也可能会诱导睡眠。 近日，一段高铁车厢二氧化碳浓度实测视频在社交平台上引发诸多讨论。 视频显示，一名手持空气检测仪器的乘客入座前，车厢内二氧化碳浓度在880pp ...

央视网消息：进入"十五五"，全国统一大市场建设向纵深推进。身处中原腹地的河南不沿边、不靠海却给自己"挖"出一条崭新的出海通道。抓 住"十五五"规划建议中"高标准联通市场设施，降低全社会物流成本"的政策机遇，河南拉着山东"组队"打造了一个国际陆港。河南的商品可以 在"家门口"直接装柜，"一箱到底"发往全球。不久前，这个陆港进入了常态化运营。 记者来到位于河南焦作博爱县的一家轮胎企业时，工人们正在为2026年的"出口第一单"打包装箱。 "一箱到底"意味着这只海运集装箱将一路向东，直接登上远洋货轮。从河南焦作到山东青岛700多公里，但在过去很长一段时间里，因为不同 运输方式之间的衔接还不够顺畅，信息共享协同机制还不够完善，货物在装船前要倒腾好几次，无形中就推高了企业的物流成本。 两米多高的工程机械轮胎和这种花纹更深的雪地轮胎都被陆续装进这个40英尺的海运集装箱里，实现了车间门口就装箱，并且"一箱到底"。 某轮胎企业负责人李华平介绍，他们把轮胎拉到港口附近，先卸货再装箱上船，这一装一卸都得产生费用。有时候还得等着查验，还有像仓储 费、港杂费等，这些费用将近有10项。 据了解，焦作当地超过85%的工业品都需要通过山东的 ...
