Does Blue Light Affect Sleep?

Does Blue Light Affect Sleep

There’s a sneaky, sleep-stealing culprit on the loose, and you’re likely falling prey to it every single night. Your nemesis? Blue light! Believe it or not, a large portion of society is affected by blue light and likely doesn’t even know it.

We’re here to shed some natural light on blue light and share ways that you can combat it. With these tips, you can reclaim your sleep cycle and get the rest your body and mind need.

The Science Behind Blue Light and Sleep

Blue light, the kind of light that our devices emit, is also abundantly found in sunlight. But why is this light messing up our beauty sleep?

Our bodies run on an internal clock known as the circadian rhythm. This rhythm is heavily influenced by light exposure, especially the blue kind. Blue light suppresses melatonin, our sleep hormone, making us feel more awake and alert. While this works great during the day, it’s not so great when you’re trying to catch some Zs.

Modern Life’s Sleep Bandit: Devices

In our tech-driven world, blue light is everywhere. We’re exposed to it constantly through everyday gadgets that have become practically indispensable:

  • Televisions
  • Smartphones
  • Tablets
  • Video game consoles
  • LED and fluorescent bulbs
  • Computer monitors

Sadly, we’re most exposed in the evenings when we really should be winding down for bed. The good news? There are some simple strategies you can employ to get back on track.

Your Defence Strategy Against Blue Light

But don’t despair! There are several ways you can protect your sleep from the blue light bandit:

Turn Off Your Devices: Try to power down at least 2 to 3 hours before you hit the hay.

Switch Up Your Lighting: Use bulbs that emit less blue light, or use dim red lights as your nightlight.

Give Blue Light-Blocking Glasses a Try: These glasses can filter out blue light, helping to boost your melatonin levels.

Tune Into Night Mode: Most devices have a “night mode” setting that shifts the display to warmer colours that interfere less with sleep.

Check Out Blue Light-Filtering Apps: These can help reduce blue light emission from your devices.

Set a Device Bedtime: An alarm one hour before bed can remind you to start winding down.

You don’t necessarily have to implement all of these tips. Even if you’re only able to try one, that’s better than nothing at all. So give them a shot; you might be amazed at the difference it makes!

Final Thoughts

Remember, we’re not demonising blue light. It has its place in our lives, helping us stay alert and productive during the day. But a little awareness and a few tweaks in our habits can help us maintain a healthy balance and protect our precious sleep.
