Although people receive natural sunlight during the day, they need electric lighting and bulbs after sunset. Electric lights are a miracle for humanity because they illuminate indoor space and outdoor space at night.
Do you know the effects of electric lights on your eyes, brain, and other body parts? Do exposure to fluorescent and incandescent light bulbs affect your sleep patterns? In today’s article, we will discuss these crucial concepts.
What is Incandescent Light Bulb?
Table of Contents
A standard light bulb, also known as an incandescent bulb, has a thin tungsten filament housed inside a sphere made of glass material. The basic idea behind incandescent light bulbs is simple – electricity runs through the filament.
The filament is thin, offering excellent resistance to electricity, turning electrical energy into heat. Bear in mind that this heat is enough to make the filament of the bulb white-hot. The filament glows due to heat.
What is a Fluorescent Light Bulb?
A fluorescent light bulb uses an entirely different method to emit light. These contain electrodes at both ends of the tube, and a gas containing mercury and argon vapors is inside the fluorescent tube.
Electrons inside the tube bump into the mercury atoms and trigger them. When mercury atoms move from the excited state to the ground state, they produce ultraviolet photons. These photons or atoms hit the phosphor coating inside the tube, creating visible light.
Moreover, a stream of electrons flows between both ends of the bulb to the electrodes. These electrons interact with vapors of the mercury atoms and float inside the bulb. As a result, the mercury atoms become more excited and return to the ground state to produce a visible, ultraviolet spectrum region.
Do these Bulbs Emit Blue Light?
Incandescent light bulbs are similar to natural sunlight. However, they have a higher spectrum on the red end, meaning these bulbs emit a small amount of blue light. Fluorescent bulbs are highly energy-efficient and contain mercury atoms.
These lights range in color from white to higher energy blue light. However, these bulbs also produce a small amount of UVA and UVB light. Ultraviolet light can harm your eyes and skin. It damages the internal structures of your eyes, including cornea and retina, leading to cataracts and other eye conditions, such as pterygium and pinguecula.
On the other hand, the blue light emitted from fluorescent bulbs can damage your retinal cells and photoreceptors because these higher energy and shorter wavelengths can penetrate your retinal cells, leading to oxidative damage in the eye.
Blue-violet light is the most harmful to your eyes. Research shows that blue-violet radiations emitted from fluorescent light bulbs can damage the retina and cause macular degeneration.
In addition, blue-turquoise light is beneficial for your eyes and vision. Not only does it maintain your sleep cycle, but it also benefits your skin. Besides, red light and green light offer a wide range of health benefits, including improved skin health and enhanced sleep. Remember, blue and green light are also used in medical therapies to treat different health conditions.
Does Blue Light Affect your Health?
Computer screens, tablets, smartphones, and fluorescent light bulbs in your home can significantly affect your health, leading to numerous conditions. Blue light emitted from fluorescent bulbs can damage your eyes, affect your sleep, cause stress, and even cancer.
Research shows that blue light reduces melatonin production in your brain. As a result, your brain does not signal your body to trigger sleep or promote a good night’s sleep. Frequent or too much exposure to blue light in the indoor space can cause insomnia.
Insomnia is a severe and chronic sleep disorder that prevents you from falling asleep at night. Not getting enough rest at night means you will feel fatigued during the day. Remember, this can hinder your day-to-day activities and reduce your productivity.
Moreover, blue light can cause macular degeneration by penetrating your retinal cells. It affects macula production in your eyes and causes cataracts, blurry vision, eye strain, and even permanent blindness.
Blue light can also cause stress and depression because it stops your brain from suppressing the cortisol hormone. On the other hand, it suppresses melatonin and dopamine, leading to frequent episodes of stress, anxiety, and panic disorder.
How to Prevent Blue Light?
Although it is impossible to completely eliminate blue light from your life, we recommend using incandescent light bulbs rather than fluorescent and LED light bulbs. Incandescent light bulbs do not produce a higher amount of shorter wavelengths, meaning you can protect your eyes and brain from blue light emissions.
In addition, you must develop a solid strategy for your screen time and limit using digital devices at least two hours before sleep. Likewise, focus on a balanced diet and perform regular exercise to increase blood and nutrient flow to your eyes, brain, and other body parts. So, when your eyes are healthy with a stronger macula, you can protect them from harmful blue light emitted from fluorescent light bulbs.
Moreover, blue light glasses are specialized glasses with anti-reflective coatings and orange or yellow tints. Wearing these glasses can protect your eyes from all kinds of artificial blue light sources, including LED and fluorescent light bulbs, computer screens, tablets, and smartphones.
Not only are blue light glasses beneficial for your eyes, but they also allow your brain and body to function correctly. Remember, your brain is the central organ in your body that controls and regulates all organs. So, you will improve body functions when you maintain your brain health by protecting it from blue light through blue-light-blocking glasses.
Research shows that incandescent light bulbs are more effective for protecting your eyes and brain from harmful blue light. Fluorescent light bulbs or tubes can emit potent and shorter wavelengths with higher energy levels, leading to many eye and brain conditions. Wearing blue light glasses can effectively mitigate the harmful effects of blue light emitted from these fixtures.
