5. You Feel Sleepy During the Day Because You Didn’t Get Enough Sleep 5. 白天犯困說明沒睡夠

One night of bad sleep—or no sleep—can definitely make you feel awful the next day, but if you’re consistently tired or feel sleepy during the day, sleep might not be the issue. Your diet, stress, or an underlying medical problem could be the cause. Even allergies or the medications you’re taking could zap your energy. Consider your sleep quality, of course, but also look into other possible causes.
一晚上沒睡好，或沒睡，第二天一定會心情不好。但是如果你白天總是疲憊不堪或昏昏欲睡，也許就不是睡眠的問題了。飲食、壓力、潛在的健康問題都可能是原因。即使是過敏或正在服用的藥物都可能擊潰你的能量。當然要關注你的睡眠質量，但也要找找有沒有其它因素。
