The Impact of Blue Light on Sleep and How to Minimise It

Introduction

 

Blue light from screens and artificial lighting is one of the biggest disruptors of sleep in today’s digital age. By understanding its effects and taking steps to minimise exposure, you can protect your sleep quality and overall health. This guide explores the science behind blue light and actionable tips to reduce its impact.

 

What is Blue Light?

 

Blue light is a high-energy visible (HEV) light emitted by electronic devices, LED lighting, and the sun. While exposure during the day can boost alertness, excessive exposure at night can interfere with your body’s natural sleep-wake cycle.

 

How Blue Light Affects Sleep

 

1. Suppresses Melatonin Production

• Melatonin, the hormone that signals your body it’s time to sleep, is reduced by blue light exposure.

2. Delays Sleep Onset

• Blue light tricks your brain into thinking it’s daytime, making it harder to fall asleep.

3. Reduces Sleep Quality

• Exposure before bed can disrupt deep and REM sleep, leading to less restorative rest.

 

Tips to Minimise Blue Light Exposure

 

1. Use Night Mode on Devices

• Activate blue light filters or night mode on your smartphone, tablet, and computer.

2. Invest in Blue Light Glasses

• These glasses block blue light, reducing its impact on your eyes and sleep.

3. Avoid Screens Before Bed

• Turn off electronic devices at least 1–2 hours before bedtime.

4. Dim Your Lighting

• Switch to warm-toned lights or use dimmer switches in the evening.

5. Engage in Screen-Free Activities

• Opt for reading, journaling, or meditating instead of watching TV or scrolling on your phone.

6. Enhance Relaxation with Moongreens

• Moongreens supports your body’s natural relaxation processes, helping to counteract the effects of blue light.

 

Blue Light Alternatives for Evening Use

 

• Replace LED bulbs with warm-hued or amber-coloured lights.

• Use candlelight or Himalayan salt lamps to create a calming atmosphere.

 

How Moongreens Helps Counteract Blue Light Effects

 

Moongreens’ adaptogens and nutrients promote relaxation and deep sleep, helping your body recover from the overstimulation caused by blue light exposure.

 

The Bottom Line

 

Reducing blue light exposure is essential for protecting your sleep and overall wellbeing. By implementing these tips and incorporating Moongreens into your routine, you can minimise the impact of blue light and enjoy more restful nights.
