How do we -- In a dark zone. Right. How do we stop it early?

我们如何——在暗区。正确的。我们如何尽早阻止它？

It means letting them establish dark zones in their calendar around school drop offs, bath time, bedtime rituals and respecting those boundaries.

这意味着让他们在日历中围绕放学、洗澡时间、就寝时间仪式建立黑暗区域，并尊重这些界限。

Below 200m in depth and we have a " twilight  zone" where only faint blue light reaches, and below 1000m we have the dark zone where  effectively all sunlight is extinguished.

在深度 200 米以下， 我们有一个“暮光区” ，只有微弱的蓝光可以到达，而在深度 1000 米以下， 我们有一个暗区， 所有阳光实际上都被熄灭了。
