Visible light is electromagnetic radiation detected by your eyes. Electromagnetic radiation refers to changes in electric and magnetic fields, leading to energy transportation at the speed of light. The sun is the biggest source of visible and invisible light, offering a wide range of health benefits, such as vitamin D production in your body. So, how to absorb the right light? Here are a few tips!
Spend some time in the Sun
Vitamin D is an essential nutrient that plays a crucial role in your body. The primary function of vitamin D is to absorb calcium, leading to bone growth, healing, and improved immune system function. Your body needs a steady source of vitamin D to perform different functions.
The sun is the natural source of vitamin D, meaning when you spend some time in the sun, it provides your body with this essential nutrient. Experts recommend spending at least 15-20 minutes in the sun if you have a light skin complexion. On the other hand, you must spend a few hours in the sun if you have a dark skin tone. However, you must do this periodically throughout the day.
Because the sun also emits invisible ultraviolet (UVA and UVB) rays, you must wear sunscreen to protect your skin from harmful UV radiations. When the UVB rays hit your skin, they penetrate the epidermis and go deeper, affecting your cellular processes.
Remember, too much exposure to UVB light can cause skin cancer. Moreover, your skin works to protect you from UV radiation. However, too much exposure to sunlight can cause health complications.
Although sunlight is good for vitamin D production, it can speed up aging, cause discoloration and skin cancer. That’s why we recommend moderate activity in the sun and wear sunscreen to protect against harmful UV rays.
Absorb Blue Light at Daytime
Blue light absorption during the day is beneficial for your physical and mental health. For instance, blue light boosts alertness, helps cognitive and memory function, and enhances your mood.
It also regulates your circadian rhythm, leading to a healthy and natural sleep-wake cycle. Exposure to blue light during the daytime can maintain your brain function, allowing it to produce hormones required during the day.
Avoid Blue Light at Night
Sunlight is the largest source of blue light. However, artificial sources of blue light are fluorescent light bulbs, compact fluorescent bulbs, LED light, computer screens, TVs, smartphones, and tablet screens.
Blue light emitted by digital devices can have long-term adverse effects on your physical and mental health. Studies show that blue light can affect both children and adults. However, researchers have confirmed that children are more prone to the harmful effects of blue light from artificial sources.
The close proximity of the screens and the amount of time children spend using digital devices is overwhelming. Almost all visible light can pass through your eye’s cornea and lens to reach the retinal cells. Blue light can affect your vision, leading to permanent damage if you fail to practice preventative methods. Some studies show that blue light exposure can cause:
Digital Eye Strain
Blue light emitted from your computer screen and other digital devices can increase glare and decrease contrast, leading to digital eyestrain. The most symptoms of this condition are fatigue, dry eyes, light sensitivity, headache, tension headaches, migraines, etc. In addition, some people also suffer from sore, irritated, and red eyes, preventing them from focusing on objects.
Too much exposure to blue light from your digital devices can also damage your retinal cells. Although your eyes have specialized structures to prevent UV light, they can’t filter the blue light. Thus, the blue light enters your retinal cells, causes damage, and leads to a condition known as macular degeneration.
Wear Blue Light Glasses
Blue light glasses are specialized accessories people use to protect their eyes from the blue light of shorter wavelengths and higher energies. These glasses have yellow or orange tints that can block blue light from entering your eyes.
Remember, some blue light glasses block only the harmful spectrum of blue light with a specific wavelength, allowing blue-turquoise light to enter your eyes. Research shows that this spectrum of blue light is beneficial for your health. Benefits of blue light glasses are:
Improved Sleep Patterns
Although walking in the sunlight can make you feel alert and boost your cognitive function, spending too much time using digital devices before bedtime can disrupt your sleep patterns. It is because shorter wavelengths can delay or disrupt the production of melatonin, a chemical released by your brain to promote a good night’s sleep.
So, using a smartphone or tablet is harmful to your health, preventing you from falling asleep faster and deeper. Wearing blue light glasses can mitigate the effects of blue light on your brain by blocking these shorter wavelengths. Even if you use a digital device for a long time by wearing blue light glasses, you don’t need to worry about sleep.
Reduced Risk of Digital Eye Strain
Staring at the screen in the daytime or nighttime can significantly affect your eyes. If you notice symptoms like dry eyes, sore eyes, fatigue, redness, and irritation, it means you suffer from digital eyestrain.
Make sure you invest in blue light glasses to prevent the problem in the future. Otherwise, the digital eye strain will affect your vision and damage your retinal cells, leading to macular degeneration.
Blue light glasses are equally beneficial for children and adults, allowing them to reduce the risk of digital eye strain even if they use their computer for a prolonged period. So, purchasing blue light is worth your investment.
Blue light can cause headaches, tension headaches, and migraines by affecting the nerves and tissues surrounding your brain in the skull. Blue light glasses can prevent headaches and migraines, reducing the risk of a light hangover.
Although you can take medications, such as NSAIDs, to relieve your headaches, too much exposure to blue light and frequent use of medications can lead to side effects. So, it is better to wear blue light glasses to reduce the risk of tension headaches and migraines.
