临睡肌抽跃症的主要症状 Hypnic jerks are associated with a rapid heartbeat, quickened breathing, sweat, and sometimes 'a peculiar sensory feeling of 'shock' or 'falling into the void''. It can also be accompanied by a vivid dream experience or hallucination.临睡肌抽跃症通常伴随着心跳加快、呼吸加快、出汗，有时还伴有“一种'震惊'或'坠入虚空'的奇特感官感觉”。有时也伴随着生动的梦境或幻觉。 A higher occurrence is reported in people with irregular sleep schedules. Moreover, when they are particularly frequent and severe, hypnic jerks have been reported as a cause of sleep-onset insomnia.据报道，作息不规律的人有更高概率伴有临睡肌抽跃症。此外，当症状特别频繁和严重时，还会导致入睡性失眠。
❶养成良好的睡眠习惯 Go to bed and wake up at the same time every day, even on weekends.按时上床睡觉和起床，即使在周末也是如此。 Make your bedroom as dark and quiet as possible, using blackout curtains or a white noise machine if needed.让卧室尽可能保持黑暗和安静，必要时使用遮光窗帘或白噪音机。 Stop using electronics at least one hour before bed.睡前至少一小时停止使用电子产品。 ❷加强锻炼 If you prefer a vigorous workout, schedule your exercise for earlier in the day to prevent it from disrupting your sleep. If you can only exercise at night, opt for low or moderate-intensity exercises like walking or yoga. 如果更喜欢剧烈运动，将锻炼安排在当天早些时候，以免影响睡眠。如果只能在夜间锻炼，请选择低强度或中等强度的运动，如散步或瑜伽。 Aim to finish your workout at least 90 minutes before bed to allow your heart rate to slow back down and prevent the occurrence of hypnic jerks.尽量在睡前至少90分钟完成锻炼，让心率减慢并防止临睡肌抽跃的发生。
