Block blue light to sleep


Ever thought about why we feel sleepy at night? Or even in darkness? This is because, in a dark environment, our body releases a hormone called melatonin, which triggers sleep.

In this fast-moving world, we want to make each hour productive without realizing the harmful effects it might have. We all love to scroll social media or binge our favorite show before sleeping. But these devices emit blue light, which confuses the body's clock and stops the release of melatonin, which affects our sleep.

Blue light is environmentally friendly and boosts attention & mood in daylight, but most disruptive at night, even dim light can interfere with circadian rhythm or body clock (i.e., sleep).

According to Harvard research, light during the daytime helps in keeping our internal body clock aligned, while exposure at night may contribute to diabetes, heart diseases, and obesity.

Here are few tips to protect ourselves from blue light at night:

  • In case you wanna use light at night, avoid LED light and use red light as they are less likely to affect our sleep.
  • Exposure to bright sunlight in the daytime improves our ability to sleep at night as well.
  • Avoid bright screens 2-3 hours before bedtime.
  • If you must work at night in emergency cases, use blue light blocking glasses or install an app that filters blue-green wavelength at night.
