国庆出行晕车怎么办?专家详解晕动病成因与预防措施

针对晕车现象,北京大学人民医院专家解析“感觉冲突”原理,评估生姜缓解效果,并提供科学用药与预防建议。

Quick Look

国庆长途出行期间,晕动病困扰不少旅客。北京大学人民医院专家刁桐湘指出,晕车源于视觉与前庭觉的“感觉冲突”。专家建议通过远眺、减少低头看手机及保持良好身体状态来预防,并提醒晕车药需提前服用,特殊人群用药需遵医嘱。

Why It Matters

晕动病(Motion Sickness)是由于人体在运动中感受到的视觉信息与前庭平衡系统信息不匹配而产生的生理反应。常见症状包括恶心、呕吐、冷汗及头晕。

国庆假期长途出行增多,长时间乘车、乘船,有人饱受晕车困扰,影响出行体验。为什么有的人一坐车就晕,有的人却完全没事?网传“含姜片、喝姜水防晕车”,这个办法靠谱吗?哪些方法可预防晕车或缓解晕车不适?

01

为什么人会晕车?

北京大学人民医院耳鼻咽喉头颈外科副主任医师刁桐湘介绍,晕车在医学上叫“晕动病”,目前最广泛被认可的解释是“感觉冲突”。

我们的平衡系统不只依靠耳朵里的前庭器官,还需要整合视觉信息和本体感觉信息来共同维持。坐在车上低头看手机,眼睛看到的是一个相对静止的屏幕,但内耳的前庭却在不断感受车辆的加速、减速、刹车和转弯。大脑接收到的信息匹配不上,就容易出现自主神经紊乱的症状,包括恶心、冷汗、面色苍白、头晕,甚至呕吐。

刁桐湘表示,“合并偏头痛、眩晕或前庭功能比较敏感的人群,更容易出现晕车症状。儿童,尤其是学龄期儿童,由于前庭发育不成熟,大脑对视觉与前庭觉冲突的解决能力较弱,也更容易晕车。”

02

网传“生姜防晕车”,靠谱吗?

刁桐湘表示,确实有一些人喝了生姜水或者含了姜片之后,晕车症状会有所减轻。但她认为,这主要是生姜里的一些成分影响了胃肠道里与恶心相关的通路,也就是说,生姜更多是起到一个减轻晕车诱发的恶心和胃部不适的作用。因此,并不能把它作为一种有明确疗效的标准治疗。特别是,不能因为喝了生姜水就忽视其他有效的预防措施。

此外,刁桐湘还提醒,对于大多数人来说,少量用生姜问题不大,但对于本身就合并严重胃食管反流症状的患者来说,大量服用姜剂会加重反流症状,要慎用。

03

预防、缓解晕车,哪些方法更实用?

刁桐湘建议,首先要尽量减少感觉冲突的出现。比如,坐车时尽量向远处看,看到道路变化,对转弯、加速、减速有预期,视觉和前庭觉匹配了,晕车症状就能减轻甚至避免。此外,不要长时间低头刷手机、看书或打游戏。条件允许的话,尽量选择车辆中相对平稳、视野好的位置,头部保持相对稳定。

其次,要保持良好的身体状态。例如,出发前保证充足睡眠,适量清淡饮食,不要空腹或过饱。坐车过程中也应尽量保证环境通风透气。

如果已经开始不舒服,就要停下手头的动作,向远处看,保持头部稳定。如果还不能缓解,在条件允许时,建议短暂停车,下车休息一下往往能明显减轻症状。

04

晕车药怎么吃?

刁桐湘介绍,目前常见的晕车药有两大类:

一类是一代抗组胺药,包括苯海拉明、茶苯海明、异丙嗪;

另一类是抗胆碱能药物,即东莨菪碱。

不同于普通止吐药,这些药物需要进入大脑,作用于前庭相关通路,降低运动刺激引起的恶心呕吐神经反应。因此,晕车人群需要提前服用。例如,苯海拉明需提前半小时到一小时服用,东莨菪碱贴片则需要提前至少4小时贴才会起效。如果晕车症状已经发作,这时再吃药可能就晚了。

此外,这两类药物都有一定副作用,包括嗜睡、口干、视物模糊,甚至心率增快、尿潴留。儿童、孕妇、老年人以及合并青光眼的特殊群体,建议先咨询医师或药师后再使用。
