TED-Ed: 你能改变睡眠规律吗？

你能改变睡眠规律吗？

一位“早鸟”在日出时醒来，精神十足地起床。而一位“夜猫子”朦朦胧胧地起来，在后半天才打足精神。多少人属于“夜猫子”还是“早鸟”？我们的作息规律是与生俱来，还是能改变的？探索我们的生物钟如何利用时间调控身体，使其运行良好。

People often identify as early birds or night owls, but most fall somewhere between these extremes. The body's circadian system, anchored by nerve cells in the brain, responds to light and helps control hormone release and sleep timing. While habits and light exposure can shift sleep patterns, biological tendencies and hormonal rhythms set real boundaries. Consistency in both sleep and exposure to natural light helps maintain a healthier, more predictable internal clock.
