Prof Czeisler recommended that students should consider setting an alarm for when to go to bed, as well as for when to wake, and be aware of the harmful effects of 'blue light' emitted by electronic screens and LED lighting, which can throw your circadian rhythm out of kilter, leading to problems falling asleep.
Czeisler 教授建议学生应该考虑设置上床睡觉以及起床的闹钟，注意电子屏幕和 LED 照明设备发出的“蓝光”的有害影响，因为这可能会导致人的昼夜节律失控，从而导致入睡困难。
