Is Blue Light Keeping You Wired?

The modern world is replete with technological advancements that keep us connected more than ever before. However, there’s a downside to this digital age: the pervasive blue light emitted by our devices. But how is it affecting your sleep and overall health? Let’s take a look.

Understanding Blue Light

Blue light is a type of light with a short wavelength, which produces higher amounts of energy. While it’s naturally present in sunlight, it’s also prevalent in digital screens like computers, smartphones, and televisions. Because we’re exposed to these devices for extended periods, our exposure to blue light has significantly increased.

How Blue Light Affects Sleep

Our bodies have an internal clock known as the circadian rhythm, which regulates our sleep-wake cycle. Exposure to blue light can disrupt this rhythm, making it harder for us to fall asleep at night. This is because blue light suppresses the production of melatonin, the hormone that controls our sleep-wake cycle.

The Health Implications

Beyond sleep disruption, prolonged exposure to blue light can lead to other health issues. Some studies suggest it may contribute to digital eye strain, which results in symptoms like dry eyes and headaches. In severe cases, it could potentially lead to age-related macular degeneration, a leading cause of vision loss.

Mitigating The Effects

Fortunately, there are multiple ways to reduce the effects of blue light:

  • Adopt the 20-20-20 rule: Every 20 minutes, take a 20-second break and look at something 20 feet away. This can help reduce digital eye strain.

  • Use blue light filters: Many devices now offer built-in settings or apps that filter out blue light, particularly useful during evening hours.

  • Wear blue light blocking glasses: These glasses have special lenses that block or absorb blue light, reducing exposure.

By taking simple steps to protect our eyes and regulate our sleep patterns, we can enjoy the benefits of technology without compromising our wellbeing. Another way to optimise your health is through chiropractic care. Book an appointment today to learn more about how we can help.
