Patients with multiple sclerosis (MS) suffer from thermoregulatory dysfunction, and repetitive yawning and sleep problems are symptoms of MS. Because yawning and sleep are involved in thermoregulation, we investigated the association between yawning, sleep, and symptom relief in patients with MS.
Sixty patients filled out a questionnaire about how often they yawned, whether yawning provided relief of MS symptoms, and how sleep affected these symptoms.
Results showed that over one in three patients reported that their MS symptoms improved following a yawn, and of those experiencing relief, nearly half reported that it lasted for several minutes or longer. Not getting a good night's sleep often made MS symptoms worse, while napping during the day provided symptom relief.
This is the first study showing that yawning provides symptom relief in patients with multiple sclerosis.
多发性硬化症（MS）患者存在体温调节功能障碍，而频繁打哈欠和睡眠问题是 MS 的症状。因为打哈欠和睡眠都与体温调节有关，所以我们研究了多发性硬化症患者打哈欠、睡眠与症状缓解之间的关系。
60 名患者填写了一份问卷，内容是他们打哈欠的频率、打哈欠是否能缓解 MS 症状，以及睡眠对这些症状的影响。
结果表明，超过三分之一的患者报告说打哈欠后 MS 症状有所改善，而在那些感到缓解的患者中，近一半的患者报告说缓解持续了几分钟或更长时间。夜间睡眠不佳常常使 MS 症状恶化，而白天小睡则可以缓解症状。
这是第一项表明打哈欠可缓解多发性硬化症患者症状的研究。
