The recent history of our civilization shows us that the development of electronics has risen up in only the last decade. Before that, we used to be busy elsewhere and this is why our bodies haven’t been able to adapt to these sudden changes around us. One particular side-effect of the digital age is the controversial blue light. It’s said that the LED and LCD screens we use today are sources of huge amounts of blue light, which can be damaging to the eyes. Blue light has been named a culprit by many health experts due to its impact on eyesight, mental health, sleep, and much more. It’s essential to understand all these details because you are exposed to this light, and knowing more about it might help you adjust your daily screen usage accordingly.
In this article, we’ll be exploring all the effects of blue light on our personal health and well-being. We’ll also look at a few preventive measures you can take to reduce its impact, as this will help you to better optimize your habits to avoid the negative effects of blue light. So let’s get to it and see what blue light can do to you and what can we do about it.
The disturbance of your sleep cycle is the number one aftereffect that blue light is blamed for. While there is a lesser amount of research on the other effects, there is plenty of evidence that it interferes with your sleep quality and keeps you more tired. For this reason, mobile phones utilize a sleep mode where the screen adopts a much more relaxing shade of red. It is said that the light sensors present in our eyes and throughout our skin can sense the difference between both blue and red light waves. Our bodies have a natural sleep cycle that depends on the light we’re exposed to. If you disturb that sleep cycle by introducing blue light more frequently, your body will have a hard time understanding that it’s actually night. Consequently, your body will not be able to release enough of the hormone melatonin, and this will cause you to feel sleepless. If you don’t get adequate sleep, you’ll feel tired most of the time and that will decrease your efficiency in other areas of life.
2. Eye Issues
Many people underestimate the effects of blue light and end up ignoring them which might cause issues to them later on. It is important to understand that it is actually very close to the UV (Ultraviolet) light which can’t be seen by the naked eye. The UV light and the blue light both carry almost similar levels of energy, and the only difference being is we can see the latter. Exposing oneself to these high-energy lights can cause numerous negative effects. These issues can range from AMD (Age-related Macular Degeneration), distorted vision, damage to the retina, or even retinal lesions. It’s important to invest in a pair of glasses that will help ease this pain, as many of us have no choice but to have exposure to our screens for hours at a time because of work. As can be seen in the options found at blockbluelight.co.uk, there are lenses that are specifically designed to filter blue light. These glasses are practical because you can wear them anywhere at any time. You can try to eliminate its usage by using a physical blue light filter or a digital app that does the same job. If you don’t avoid being exposed to it by decreasing its use every day, you’ll end up with similar serious disorders too.
3. Mental Health
The effects of blue light on the mental health of animals have been extensively studied and the researchers have found that the animals who were exposed to higher levels of blue light exhibited depressive symptoms. However, this applies only in the case of nighttime exposure, and any exposure during the day might have the opposite effects. This same harmful blue light has been successfully used to treat Seasonal Affective Disorder (SAD), to boost memory, enhance cognitive functions, and even skin disorders like acne. The kind of light that we’re exposed to during the night is significantly strong, and it ends up causing insomnia, anxiety, lower cognitive functions, and much more. It’s important to avoid exposure to it during the night by taking measures like putting the phone away, reading a book before bed, eliminating binging sessions, and many other creative measures with no gadgets involved.
4. Impact on Kids
The impact of blue light on a young and growing child is unknown to many parents. Had they been aware of the possible consequences, they would’ve taken preventive measures immediately. Blue light can raise the risk of chronic conditions like obesity, problems in focusing, and even nearsightedness. Even the eyesight is negatively impacted by it and carelessness in this part can damage your child for the rest of their lives. Try to restrict the use of all electronic devices to at least an hour before bed. You should also impose a strict sleeping schedule so that there are no late-night binging sessions that might cause any undesirable issues to them. As parents, children are the most important thing in our lives and their health is what matters most. Alternatively, try to let your kids go out to play or read a book that will help eliminate the excess blue light use.
