We are currently in the digital age filled with smart devices like the smartphone, laptop and tablet. While these devices could easily be named the biggest inventions of the century, they are also double-edged swords with both benefits and drawbacks. The rise in their usage has been perceived by scientists to be tied to that of rising cases of insomnia.
While the science behind this isn’t 100% certain, a sufficient number of studies have consistently shown there is a strong link between blue light and sleep depravity. Despite the little uncertainty of its exact impact, sleep is too vital to the normal functioning of the human body to take a chance on blue light. Discovering how blue light filters help you sleep better is certainly a safe bet that will assist you to understand the hullabaloo surrounding them.
1. They Help Increase Melatonin Production
Scientists have termed the hormone melatonin the sleep tonic. Its production is perceived to signal the body of impending sleep. Exposure to blue light has been postulated to inhibit its production. While low levels of melatonin is beneficial during the day, at night the suppression of melatonin is nothing but detrimental to people craving a good night sleep. Low melatonin levels equates to high alertness and is counteractive to the achievement of sleep.
In an age where the use of smart devices is almost unavoidable at night, exposure to blue light before sleeping is almost impossible. But with the help of blue light filters, the effect of blue light at night is greatly reduced. Consequently, increasing the production of melatonin and chances of sleeping quickly and peacefully.
2. They Help Increase Orange Light
How blue light filters work to help you sleep better is they reduce the amount of blue light in smart devices. As a result, they substantially increase the intensity of orange light. While the blue light is counteractive to a good night sleep, the orange light is quite the opposite. It has been shown that exposure to orange light stimulates drowsiness. While the exact cause of this isn’t known for certain, it is postulated by scientists that this behavioural inclination dates back to early mankind when sunset marked the end of the day and the beginning of sleep.
It is deduced that the orange light which is dominant during the sunset triggered drowsiness in the early man and that this trigger is still active until today. However, because of the saturation of blue light in smart devices, its effect is hampered. Luckily, with the help of a blue light filter, you can increase the impact of orange light emitted by your device.
3. They Help Reduce Alertness
There is an internal clock in our bodies that stipulates the time for sleep and that of alertness. One of the criteria it prudently uses to guide it is its environment simply put, sunset or sunrise. Sunrise signals the body to wake up and be alert while sunset does the opposite. It triggers the body to begin the process of shutting down and sleeping. Smartphones which are overflowing with blue light, not only disrupt the body’s shutting down process, they also encourage alertness which is counteractive for a good night’s sleep. Falling asleep will, therefore, be quite difficult with excessive exposure to blue light. By reducing the intensity of blue light, you also reduce your alertness and that’s how blue light filters work to help you sleep better.
4. They Help Prevent the Resetting of Your Body’s Internal Clock
As it has been earlier stated, it’s the body’s internal clock that’s responsible for inducing sleep and alertness. It may not be entirely clear how it times itself but the idea is that the body uses external environmental cues to guide the process. Again, this is where blue light and orange light come into play. With human beings having extended exposure to blue light from smart devices, the body misses the essential environmental cues that stimulate its timetable for different activities including sleep. This leads to difficulty in getting shut-eye at your preferred time and also to fatigue at waking time.
When the body has difficulty inferring the right time to fall asleep and to wake up, there is a state of body confusion. This essentially means that the body struggles to set pertinent body activities like sleep due to conflicting cues. It is an all in all very uphill process which can be simplified tenfold by the use of a blue light filter. How blue light filters work to help you sleep better is they prevent the upsetting of natural body patterns. By reducing the effect of the blue light on the eye, they not only signal to the body to begin the sleep process, they also prevent the resetting of the internal clock.
Blue light emitted by our numerous devices is being linked to the rising cases of insomnia. While a solution would be abstinence of smart device usage at night, this solution is considered by most people too extreme and absurd. And in this day and age, no one can blame them. Luckily, a solution has been developed that not only reduces the likelihood of insomnia but also allows you to comfortably use a smart device at night. The solution is a blue light filter. With it, you will not have to turn to the drastic measure of forgoing your smart device at night or miss out on a good night’s sleep. A comprehensive look at how blue light filters help you sleep better proves that you can have the best of both worlds. At Ocushield, you will be offered a wide array of blue filters to choose from which will serve this purpose beautifully.
