A Guide to activating and protecting your mind and body.
As Loving, Victorious Beings, we strive to live in harmony with nature’s rhythms. One of the most profound ways to do this is by managing our exposure to blue light, a powerful influencer of our energy levels, mood, sleep quality and overall health. In this blog, we’ll explore how to embrace blue light in the morning, block it in the evening, and harness its power for a healthier, more vibrant life.
We are only starting to understand the profound impact that blue light exposure can have on our lives for the better or worse and we cannot emphasise enough the potential heath risks unmanaged blue light exposure in today’s technology age can pose.
Excessive exposure to blue light, particularly from artificial sources like screens and LED lights, has been linked to a variety of physical and mental health issues. Here are some of the key illnesses and conditions associated with prolonged blue light exposure:
1. Sleep Disorders
• Impact on Melatonin Production: Blue light suppresses melatonin, the hormone responsible for regulating sleep-wake cycles. Overexposure in the evening can delay sleep onset and disrupt overall sleep quality.
- Conditions: Insomnia, delayed sleep phase syndrome (DSPS), and general sleep deprivation.
2. Eye Strain and Damage
• Digital Eye Strain (Computer Vision Syndrome): Symptoms include headaches, blurred vision, dry eyes, and discomfort from staring at screens for extended periods.
• Retinal Damage: Prolonged exposure to high-energy blue light can potentially contribute to retinal cell damage, increasing the risk of age-related macular degeneration (AMD): A condition that can lead to permanent vision loss.
3. Mental Health Disorders
• Depression and Anxiety: Disrupted circadian rhythms can contribute to mood disorders. Lack of restorative sleep has been linked to higher risks of anxiety and depression.
4. Obesity and Metabolic Disorders
• Disrupted Metabolism: Misaligned circadian rhythms from blue light exposure can alter metabolism, increase appetite, and reduce glucose tolerance, contributing to:
- Obesity.
- Type 2 diabetes.
5. Cardiovascular Issues
• Poor sleep caused by excessive blue light exposure is associated with a heightened risk of heart disease, high blood pressure, and stroke.
6. Cancer Risk
• Shift Work Sleep Disorder: Chronic disruption of circadian rhythms from nighttime exposure to blue light has been classified by the WHO as a probable carcinogen.
• Breast and Prostate Cancer: Studies have linked blue light exposure at night to increased risks of hormone-related cancers.
7. Neurodegenerative Diseases
• Disrupted sleep and circadian rhythms may increase the risk of neurodegenerative disorders such as Alzheimer’s disease and Parkinson’s disease.
But not all is bad. Blue light is equally important for us as it can be dangerous. Understanding how to manage it is key to healthy life.
The Morning Glow: Why Blue Light is Your Best Friend at Dawn
Blue light plays a critical role in activating our system, setting our internal clock, and boosting our energy for the day ahead. When exposed to blue light in the morning, our brain reduces melatonin production (the sleep hormone) and increases alertness. This process is mediated by melanopsin, a photopigment in our eyes that responds specifically to blue wavelengths.
The best way to soak up this natural blue light is by spending time outdoors in the morning sunlight. Just 15-30 minutes outside between sunrise and mid-morning can reset your circadian rhythm, elevate your mood, and optimize your focus for the day.
Amplify the Effect: Blue Color Therapy Glasses
For days when you can’t spend much time outside, or if you’re in an environment with limited natural light, wearing blue color therapy tints can amplify the positive effects of blue light. These specially designed lenses mimic the energising effects of sunlight, helping to jumpstart your system and align your body with the day’s natural rhythm.
The Evening Wind-Down: Why Blocking Blue Light Matters
As the day progresses, our bodies need to prepare for rest and recovery. Exposure to blue light in the afternoon and evening can interfere with this process by suppressing melatonin production. Melatonin is essential for deep, restorative sleep and overall well-being.
Blue light also impacts melanopsin, making it harder for your brain to recognize when it’s time to wind down. This is especially problematic in today’s world, where screens dominate our evenings.
How to Block Blue Light for Better Sleep
Managing blue light in the evening is key to achieving a healthy sleep-wake cycle. Here’s how to do it:
1. Use Blue Light Blocking Glasses:
Wear red, amber or orange-tinted glasses that filter out blue light starting in the late afternoon. These lenses help your brain transition to evening mode by allowing melatonin to be released as intended naturally.
2. Dim Screens and Lights:
Switch your devices to night mode or use apps that reduce blue light emissions, like f.lux or Apple’s Night Shift. Consider using dim, warm-hued lighting in your home after sunset.
3. Reduce Screen Time Before Bed:
Aim to power down screens at least 1-2 hours before bedtime. Instead, engage in calming activities like reading, meditating, or journaling under soft, warm light.
4. Prioritize a Sleep-Friendly Environment:
Ensure your bedroom is cool, dark, and free from artificial light pollution. Blackout curtains and dimmable lights can make a big difference.
Understanding the Science: Blue Light, Melanin, and Melanopsin
• Melanin: This pigment protects our skin and eyes from harmful UV rays but also plays a role in how we absorb and process light.
• Melanopsin: Found in the retina, this photopigment detects blue light and signals the brain to regulate circadian rhythms. Too much blue light in the evening confuses this system, delaying melatonin release and disrupting sleep.

Melatonin, often called the “sleep hormone,” plays a critical role in regulating the body’s circadian rhythm, which governs sleep-wake cycles. Produced by the pineal gland in response to darkness, melatonin helps signal the body that it’s time to sleep, promoting restorative rest. Beyond its role in sleep, melatonin has potent antioxidant properties, helping to protect cells from oxidative stress and supporting immune system function. It also influences mood, as disrupted melatonin levels are linked to conditions like depression and anxiety. Additionally, melatonin impacts metabolic health, aiding in weight regulation and glucose metabolism. Its overall effects on the body and mind make it vital for maintaining balance, energy, and long-term health.
By managing your exposure to blue light, you’re not only protecting your sleep but also supporting your body’s natural energy rhythms and overall well-being.
By embracing blue light in the morning and blocking it in the evening, you can align your life with nature’s rhythms and thrive as the Victorious Being you are. Let sunlight energize your mornings, and let warm, calming light guide you into restful nights.
Your body knows how to heal, grow, and operate very well —let the light help it along the way.
