The Real Dangers Of Artificial Light To Your Health
We are surrounded by artificial light sources in our daily life, whether it is the light in our office or from our phone screen. Artificial light can impact your health in a variety of ways, but why is this a problem? The problem lies in the color spectrum that artificial light uses. Nearly all types of light from the screens we use including our laptops, televisions, tablets and phones include a blue spectrum that is more intense than normal sunlight. Sunlight, by the way, incorporates all of the color spectrums.
The blue color spectrum can impact your health in several ways. First, blue light as part of normal sunlight is required by the body for just part of the day. Blue light is what triggers your body to get up and go. Take a plant, for example: The blue spectrum is the wake-up call for plants to open their blooms. The same is true for humans, it is the signal that tells the human body when it is time to get up and out of bed or to start the day. This is a unique spectrum with a unique function that wakes our body up. Blue light is also tied into our metabolism.
Digital Blue Light
We live in a digital world; we can’t escape that fact. We’re surrounded by artificial screens every day, including those found at work. Our computers put out a large amount of the blue spectrum light. In fact, laptops and computer screens create more of this light than any other digital screens we encounter. Think about how much time we spend in front of a computer or laptop! This means we are being exposed to blue light for longer hours and different hours outside of daylight for days on end. It can really disrupt our circadian rhythms.
So what are the impacts of being assaulted by blue light on a daily basis? The impacts can be long-lasting and detrimental to your health. If you’re constantly impacted by blue light after normal daylight hours, it can confuse your body. For example, you follow a normal rhythm called a “circadian rhythm,” and the blue light from your laptop can change that rhythm. It means that your body will get out of sync with the natural daylight cycle and react in a negative way. The long-term effects of blue light exposure is currently hot topics in scientific circles, and it is being studied by several universities.
