Wearing these glasses to bed can improve sleep quality

Insomnia is a common problem. But the good thing is around 75 per cent of people with insomnia recover before it turns into a persistent problem. As per the Center for Disease Control and Prevention (CDC), ignoring poor quality of sleep is linked to various problems, ranging from type 2 diabetes, heart disease, obesity to depression.

We all try various ways to sleep better but a new study has revealed that there is an accessory that can come to your rescue. According to new research published in the Journal of Applied Psychology, your sleep can be improved by wearing blue-light filtering glasses while you sleep.

The study

The scientists collected data from 63 people and found that wearing blue-light filtering glasses is an effective intervention to improve sleep, the attitude at work and performance.

We all have heard of people wearing blue-light glasses while working on a computer all day long, but the glasses can help get some rest is a new development.

It has been found that wearing blue-light glasses creates a form of physiologic darkness, thus improving both quality and quantity of sleep.

How blue light affects sleep?

The truth is that blue light is an unavoidable factor of modern life. As per studies, humans previously lived in a state where they were lit only by the Sun and developed a biological clock or circadian rhythm.

The length of this rhythm varies for each human being, but it is usually around the 24-hour mark. It’s longer for the night owls and shorter for early risers.

The daylight helps keep us aligned with this rhythm, while artificial light disrupts it. Artificial lights with shorter wavelengths can suppress the production of the sleep hormone melatonin and is especially bad at night.

Experts have found that blue light suppresses the melatonin for twice as long as the green light. Blue light time can be cut by cutting the time we spend while watching tv, phones and laptops.

So, to have a good night sleep, stop scrolling through your Instagram feed and try sleeping wearing your blue light glasses.
