Have you ever questioned why you have trouble sleeping at night?
It's not just you. Worldwide, millions of individuals struggle with sleep issues. The causes of not getting enough sleep, however, can vary from person to person and are numerous.
Blue Light is one of the less well-known factors in restless sleep.
Blue light has a negative aspect while being environmentally favorable. It may interfere with your sleep and raise your chance of developing a number of illnesses.
The biological clock in your body should not be exposed to artificial light. However, not all artificial lighting is made equally. Some things significantly impact your sleep more than others. One of the most terrible types of light is blue light.
Explaining Blue Light
We are affected differently by various light wavelengths. Blue light speeds up mood, focus, and reflex times. When we need to be active during the day, these reflexes come in handy. However, at night, the blue light is bothersome due to these same characteristics.
Our biological clock may be seriously disrupted by increased exposure to blue light, which is produced by practically all electronic devices with displays.
Light and Sleep: A Relationship
Every person has a somewhat unique circadian rhythm, also known as the biological clock in the body. Although 24 14 hours on average, early risers and late sleepers have slightly different circadian cycles. According to research, sunshine keeps our internal clock in sync with the outside world.
Is nighttime exposure to artificial light harmful?
There may be a link between nocturnal light exposure and heart disease, obesity, and diabetes, according to certain scientific research.
In order to determine the relationship between nocturnal light exposure and diabetes and obesity, Harvard researchers conducted a study. Ten participants were placed on a schedule that gradually changed the time of their internal clocks by the researchers. A rise in blood sugar levels and a fall in leptin levels were seen in the subjects. A hormone that is produced naturally, leptin is crucial for controlling hunger.
In addition, artificial light inhibits the hormone melatonin, which is important for maintaining our regular sleep-wake cycle.
Even weak light can cause melatonin secretion to be disturbed, which affects our sleep-wake cycle. Our capacity to sleep is impacted by exposure to just eight lux, a brightness level that is far lower than what most table lamps and night lights emit.
One of the reasons why so many individuals often struggle to get a decent night's sleep is exposure to nocturnal light. Numerous illnesses, including but not restricted to diabetes, heart disease, and depression, are associated with sleep deprivation.
How Does Blue Light Impact Sleep?
Blue light has a stronger impact on melatonin secretion than any other artificial light does.
Blue light's impact on sleep was contrasted with that of green light, according to Harvard researchers. Participants were exposed to blue light for 6.5 hours, followed by green light for the same amount of time. They discovered that melatonin synthesis was reduced by blue light for nearly twice as long as it was by green light. It had twice as great of an impact on the internal cycle of sleep and wakefulness.
Similar results were obtained by another study conducted by the University of Toronto. In this study, the levels of melatonin in subjects exposed to blue light wearing blue-blocking eyewear were compared to subjects subjected to typical dim light without eye protection. The discovery that the first group and the second group had equivalent amounts of melatonin supports the hypothesis that blue light may inhibit the generation of melatonin.
How Can You Protect Yourself at Night from Blue Light?
What sort of lighting should be used in bedrooms and living rooms if exposure to blue light at night is hazardous for sleep?
Extra warm white LED lights are the solution since they contribute to the ambiance of coziness, warmth, and relaxation that is perfect before bed.
However, be careful to only use CRI90+ bulbs since they produce the most even lighting. Since we place a high focus on your health, LiquidLEDs only sells LEDs with CRI90+.
Additionally, you want to think about employing dim red LED light bulbs as nightlamps. Red wavelengths were discovered to have the least impact on the circadian rhythm of all the wavelengths.
