CHINA DAILY: Why night lights should set off red warning signs

Description

Bright lights and screen time are often associated with damaging sleep and insomnia, especially among children.

Various apps and features on our phones claim to reduce the damaging "blue light" emitted by our phones, which is said to keep us awake at night.

However, recent research suggests that screen time does not affect adult sleep and insomnia as much as we think, and that apps that change the color filter on our phones may seem more comfortable, but may actually be making the issue worse.

In China especially, the link between screen time and sleep hygiene is full of urban myths, and so navigating this sea of advice is often difficult.
