Blue light’s impact on sleep is less than anticipated<\/figcaption><\/figure>\n<\/div>\nFor years, poor sleep has been blamed on the blue light emitted from phones and laptops. But emerging research suggests that the real issue may be much broader than screen exposure alone.<\/p>\n
According to a report by BBC<\/i>One study examined the effects of blue light elimination while sleeping on the human eye. The research used blackout curtains and special glasses to test the effects of screens, but found that screens had less of an impact than researchers expected.<\/p>\nFear of blue light may be exaggerated<\/h2>\n
People started worrying about blue light after researchers published a 2014 study that showed that people who used screens before bed experienced delayed sleep and reduced melatonin production. Blue light impacts how our body maintains its internal clock system, which regulates our sleep and wake cycles.<\/p>\n
Researchers today recognize that real environments show different results than scientific laboratory experiments. According to Stanford University expert Jamie Zeitzer, screen light has low power, making it unable to disrupt sleep when used at night.<\/p>\n
Studies show that human exposure to light during the day has a greater effect. In modern times, people who live indoors face restrictions that prevent them from seeing bright natural sunlight causing them to lose the ability to tell whether it is daytime or nighttime. During cloudy weather outdoor light levels reach approximately 10000 lux, which is higher than the brightness found indoors and on phone screens.<\/p>\n
Experts recommend that people should spend time outside in the morning, while they should limit exposure to light after sunset to achieve better sleep results.<\/p>\n
Researchers study how people use their devices because they believe device use has a more harmful effect than exposure to light. The brain remains active during late night scrolling, which includes engaging content and social media activities, resulting in delayed sleep.<\/p>\n
Zeitzer explains that people stay awake because they perceive more content than actual light exposure. The combination of essential bedtime exercises and nighttime blue light elimination provides better sleep benefits than blue light elimination alone. Effective methods include reducing lighting in the evening and increasing daylight and maintaining consistent sleep patterns.<\/p>\n<\/p><\/div>\n
