Research has long proven that blue light is terrible for your health. Countless clinical studies prove that blue light exposure can make headache pain and migraine symptoms worse. This is because it affects the specific neural pathway that connects the eye to the brain. These changes are believed to interfere with proper vision transmission. In addition, blue light is also associated with several adverse physiological effects. To learn more about the impact of blue light, read on.
According to recent studies, nearly seventy-two percent of American parents admit that their children spend more than two hours each day in front of a screen. That means that they spend more time in front of a screen than outside. Common Sense Media estimates that kids under eight spend an average of more than two hours each day in front of a screen—children ages eight to 10 double this, spending up to six hours a day. Teenagers spend eight to nine hours a day staring at a screen, which is enough to trigger computer vision syndrome. The result of visual stress can lead to tiredness, irritation, and even headaches.
The ideal amount of screen time is challenging to determine, but it is recommended that people limit their screen use to six hours each day. In addition, screen use should be limited to one hour before bedtime. Also, people should take frequent breaks. A good rule of thumb is to keep your screen at arm’s length. Another option is to use glasses like the Blue Light Glasses for kids from Felix Gray to protect their eyes, magnify text and take breaks from social media. And, when you’re finished using your screen for the day, take a break and go outside for some fresh air.
Interferes with circadian rhythm and macular degeneration
Unlike tobacco, which has long been believed to be healthy, scientists are now warning about the adverse effects of blue light. Studies have shown that prolonged exposure to blue light interferes with your circadian rhythm, which regulates sleep and wakefulness. Exposure to blue light also increases cortisol and ghrelin levels in your body, hormones that are associated with hunger and alertness. While it is still unclear whether blue light can harm your health, limiting your exposure to it could protect your mental and physical health.
Studies show that prolonged exposure to blue light can lead to age-related macular degeneration and eye strain, but they are not responsible for the onset of these conditions. More than 10 million Americans suffer from macular degeneration, the leading cause of vision loss. While macular degeneration is incurable, there are still steps you can take to limit your exposure to blue light. For example, taking breaks from the screen several times a day can help to limit your exposure.
Overexposure to blue light disrupts the circadian rhythm, a hormone produced by the brain to help you sleep at night. This hormone, known as melatonin, helps the body regulate sleep and wake cycles. Overexposure to blue light disrupts the circadian rhythm, and it’s not surprising that sleep is affected. In addition to being a detrimental effect on the sleep cycle, excessive blue light also inhibits the production of melatonin, a hormone that regulates the sleep-wake cycle.
While many people cannot turn off sources of blue light after dark, they can minimize their exposure by using non-blue-light lamps when in bed. Natural lighting is another way to cut down on blue light. In addition, many electronic devices have a night mode that reduces the amount of blue light they emit. If you can’t turn off all your devices at once, try a Power Down Hour. This timeframe should begin at least 60 minutes before bed.
Aging of the skin
The effects of overexposure to blue light on the skin may not be immediately noticeable, but overexposure to blue light can lead to the accelerated aging of the skin. Blue light affects the circadian rhythm of skin cells, which can result in hyperpigmentation, wrinkles, and other visible skin signs. Blue light is also linked to a disruption of collagen production. When skin cells are not replenished, these conditions can progress and cause severe skin damage.
Exposure to blue light increases skin damage. While blue light is important for sleep and general health, prolonged exposure to blue light through electronic devices can damage the skin. Fortunately, topical antioxidants can help repair any damage caused by blue light, and new ingredients in skincare products may prevent damage in the future. However, this information isn’t yet conclusive. Further research is needed.
