It’s not just that we use mobile phones every day but, but we use them all day long. Most of us are never separates from this device, cannot even imagine an hour of their time without a mobile phone. Of course, the advantages of modern technology are huge, and we do not need to emphasize them, but as it usually happens, they come in a package with negative consequences, which are neither small nor negligible.
About how much UVA and UVB rays are hazardous is written and spoken, but lately more and more is being said about blue or HEV light which can be equally harmful and comes from screens and devices like mobile phones.
The sun’s light, undoubtedly, is the primary source of blue light – digital devices (TVs, computers, tablets, mobile phones …) and fluorescent energy-saving LED bulbs to emit only a fraction of that radiation. According to a statistical analysis of the American analytical company Nielsen Total Audience, adult Americans spend more than 10 hours a day in front of the screen of the mobile phone or computer, which confirms that more blue light absorbs from technological “waves” than from the Sun. Dermatologist points out that we spend eight hours in front of a computer for four working days with the same amount of solar energy as 20-minute sunshine in the middle of the day.
Blue light stimulates oxidative stress, much like UVA radiation – a well-known reason for premature aging. Compared with UVA and UVB rays, blue light can penetrate deeper skin layers, up to the dermis, where collagen and elastins are found. The cumulative effect can cause inflammation, loss of tonus, and relaxation of the skin. Exposure to blue light during the night does disturb not only our sleep but also harm the natural biorhythm of skin cells. If we read on the tablet or mobile phone in the evening, we will find it more difficult to fall asleep because the glittering light affects the secretion of melatonin, the so-called sleep hormone, and we know how good a dream is necessary for beauty.
The elements that most of the mobile phones are made of, more precisely their armor, are chromium and nickel, which are considered to be very common allergy triggers, which in the case of the skin most often manifest themselves in the form of severe itching and irritation, or contact dementia. For example, if you notice that your skin is hand-held, or if your face is often touching while you’re ticking mobile, itchy, and there is no other real cause for such an occurrence, then it’s very likely that this condition is caused by frequent use of a mobile phone.
Dark spots on the skin
It has been proven that blue light can also lead to excessive aging of the skin, in the form of dark spots, skin problems such as hyperpigmentation. If you notice such changes, you definitely need to take extra care – it is recommended that you use Bluetooth for example, as well as additionally protect your skin with a sufficient dose of antioxidants, i.e., to use skin care serums containing vitamin C, E, and niacin. This treatment will help you to lighten the darker parts of your skin.
Reduce blue light
Without technological tools, we cannot breathe, but for a start, we can limit the time we spend with the screens of mobile phones and various devices. We can also install physical filters to reduce blue light or install applications (for example, Bluelight Filter for Eye Care) that automatically cover the screen with a reddish layer when the night falls. On some smartphones, blue light can be turned off (the so-called night mode or night shift mode), and if your smartphone does not have this option, you can reduce the brightness of the light yourself to a minimum. This will preserve your health and skin and eyes.
