You might be asleep的意思|示意

The constant noise of a fan might work for you too. Having a music system in your room can be a source of interfering with your ability to fall asleep if you're sensitive to it.[24]

风扇连续不断工作发出的声音也会影响你的睡眠，如果你对这种声音很敏感，在你的房间安装一台音乐播放器播放一些音乐可以助你入睡，但你要注意使用音乐带给人的乐趣不要滥用。

If you exercise too close to bedtime, you might be too energized to fall asleep.

如果你在靠近休息时间锻炼，你可能会太兴奋而难以入睡了。

And thus you might be tempted to use alcohol to fall asleep the next night and the night after that and so on.

因此，第二天晚上你可能又会忍不住要靠饮酒助眠了。由此，一个恶性循环便产生了。
