See Full Reference to sleep problems stemming from electronic devices that emit blue light. Numerous studies have established a link between using devices with screens before bed and increases in sleep latency, or the amount of time it takes someone to fall asleep. Additionally, children who use these devices at night often do not receive enough high-quality sleep and are more likely to feel tired the next day.

See Full Reference. Unlike blue light, red, yellow, and orange light have little to no effect on your circadian rhythm. Dim light with one of these colors is considered optimal for nighttime reading. Portable e-readers like the Kindle and Nook emit blue light, but not to the same extent as other electronic devices. If you prefer to use an e-reader such as a Kindle or Nook, dim the display as much as possible.

Establish a Relaxing Bedtime Routine: A regular bedtime that ensures an adequate amount of rest is essential for healthy sleep. The hour before bed should consist of relaxing activities that don’t involve devices with screens.

See Full Reference reduce blue light emissions and decrease the display’s brightness setting. You should manually dim the display if your device does not automatically adjust the brightness in nighttime mode.

The blue light emitted by many devices disrupts the natural production of melatonin, a hormone that facilitates sleep and can throw off your circadian rhythm.

Set consistent “screens off” and “lights out” times: Have a consistent deadline for when you’re going to shut off your electronics and when you’re going to actually turn off the lights to fall asleep. Having a firm “screens off” time keeps you from staying up to check just one more email or watch one more episode. It also helps you get used to a set period without screen time and promotes a regular sleep schedule.

Set boundaries with friends, family, and work: Many people think they need to sleep with their phone nearby because they may have to immediately respond to something important. Unfortunately, this perceived need to be connected 24/7 means you’re constantly at risk of sleep disruptions during the night. To get away from the “always-on” mindset, tell friends, family, and work colleagues that you won’t be accessible during the late evening and early morning. Setting this boundary gives you the freedom to make your bedroom technology-free without worrying about missed messages, calls, or emails.

Go old school:Folks who are “on-call” through the night such as those who work in healthcare, 24-hour operations, technology sectors, or transportation, can consider installing a landline. This will keep screens away while still remaining accessible.

There are various products on the market designed to reduce ambient artificial light pollution. F.Lux is a free software program that filters blue light from computer screens. "Smart bulbs" automatically dims light bulbs with the setting of the sun. At the Consumer Electronics Show, health tracker startup, Misfit, has launched a smart bulb that is timed to change colors with a user"s sleeping patterns.

But the best solution is also the most low-tech: "blue blocker" sunglasses. These awkward, wide-lens, orange-tinted sunglasses look like they fell out of a Miami Vice fan club for cataract patients, but they work wonders. Without blue blockers, study participants experienced a 46 percent reduction in the brain"s sleep chemical, melatonin. As such, they"ve been successfully used to improve ADHD symptoms in sleep-deprived youth. Another study found that they "may be useful in adolescents as a countermeasure for alerting effects induced by light exposure through LED screens."

Parents, educators, and clinicians express concern about whether excessive use of screen media among young people affects sleep and wellbeing. In this article, we provide an overview of the current science on screens and sleep, with a focus on recommendations to reduce the potentially problematic influence of screen time on pediatric sleep. We then review how impaired sleep in pediatric populations may lead to a range of adverse behaviors, physical health problems and well-being outcomes. We begin with a summary of the two consensus statements on child and adolescent sleep needs. Then we summarize the range of screen habits among youth, focusing on screen habits at bedtime. Next, we review current literature on evidence of the effects of youth screen habits on sleep, and the mechanisms by which screen habits may impact sleep. We conclude with evidence-based strategies to improve sleep through sleep-friendly screen-behavior recommendations and other take-home messages for families and practitioners.

Exposure to the light emitted by screens in the evening hours before and/or during bedtime is another likely mechanism by which use of screen media negatively impacts sleep. Screen-based light may affect sleep via several pathways:increasing arousal and reducing sleepiness at bedtime,

Clinicians can help families improve their sleep health and screen media habits by encouraging parenting marked by high levels of warmth and support, as well as limits that are clearly communicated, consistently applied appropriate to the child’s behavior and context, and allow for developmentally appropriate autonomy(i.e. an authoritative parenting style). Box 1) All parents should begin instilling family bedtime routines and healthy sleep habits early in life, and adjust these routines as youth mature (See Box 2). If the youth health behaviors and habits become part of the child’s own daily routine, she will be better able to take charge of her own sleep health behaviors when this becomes appropriate in later years. For younger children, these routines mean establishing household rules related to screens and sleep early on. For older children and adolescents, they involve open conversation about the core reasons for behaviors. This proactive and engaged parenting style promotes cooperation and parent-child shared goals for children’s health and well-being, and aims to help children develop self-regulation skills, and eventually increasing autonomy to govern their own behavior.

For teenagers presenting with excessive screen time, a few clinical pearls may help families to follow the recommendations laid out in Box 1 and 2, below. First, one must always focus on the chief complaint, what brought the patient to seek help in the first place. In cases of excessive nighttime screen media use, children and adolescents are often seen in the clinician’s office for poor academic performance or lack of concentration in school. Upon taking a careful history, the clinician often discovers a significant lack of sleep, often attributable to patients staying up late while using mobile devices, computers, or videogames. Clinicians must discover the underlying factors (e.g., social or family stress) which drive the patient to use the screens in the late hours. Addressing such factors directly may be essential to motivating families to achieve healthier screen habits.

The currently-supported mechanisms underlying the relationship between screen media habits and sleep outcomes include (1) displacement of time spent sleeping by time spent using screens, (2) psychological stimulation from screen-media content, and (3) alerting and circadian effects of exposure to light from screens.

Joanna Cooper, M.D., a neurologist and sleep medicine specialist with the Sutter East Bay Medical Foundation, says bright screens stimulate the part of our brain designed to keep us awake. Looking at a brightly-lit screen prior to sleep can make for a restless night.

Device screens produce blue light, Dr. Cooper says, which is the part of the light spectrum most active in our sleep cycle. Stimulation of this part of the brain suppresses production of melatonin, making it difficult for many people to “turn off” their brains and fall asleep.

“The light from our screens can delay our transition to sleep, even if we are engaged in some soothing activity online,” Dr. Cooper says. “But it’s more likely that our evening texting, television shows or video games are stimulating in themselves, keeping the brain busy and wound up, and even causing adrenaline rushes instead of calm.”

He and his team plan to discover targets for treatments that will counter circadian rhythm disruption, which can result, for example, from artificial light exposure.

It’s become a virtually unchallenged piece of conventional wisdom that exposure to blue light—the type emitted by electronic device screens—is bad for sleep. That thinking has spurred a mini-industry of innovations meant to stop those effects, like warm-toned “night mode” settings on gadgets and glasses thatclaim to block blue light.

There are plenty of reasons other than sleeplessness to not spend all your time staring at screens, from possiblemental health consequences to their correlation witha sedentary lifestyle. But in terms of eye health, there’s no reason to spend your time and money looking for blue-light-filtering glasses or gadgets, says Dr. Matthew Gardiner, an ophthalmologist at Massachusetts Eye and Ear. While some people report improvements in eye-strain orheadaches after using these products, Gardiner says there’s no research to suggest blue light damages your eyes. “If you feel more comfortable, then that’s fine, but it does not do anything for the health of your eyes,” he says.

With the spring season bringing warmer weather and brighter days, spending time in the sun certainly seems like the ideal way to celebrate Earth Day. After all, the sun makes the Earth the place we know and love by promoting plant growth, maintaining ecosystems, and keeping us warm. The sun also gives off blue light, helping us feel awake, energized, and ready to take on the day’s activities. However, digital devices such as smartphones, TVs, and computer screens also emit blue light, which can impact our ability to fall asleep.

Dr. Dagny Zhu, MD, an ophthalmologist, and member of the Eyesafe Vision Health Advisory Board (VHAB), tells us how the blue light from our digital screens may affect our sleep and overall well-being. “You may have heard about the linkage between using digital devices at night and sleep,” says Dr. Zhu. “Using devices at night tricks our minds into thinking its daytime by suppressing the release of melatonin, the sleep hormone.”

The decrease in melatonin has also been related to delays in sleep onset or alterations in sleep caused by a certain kind of light which is found on screens and mobile devices.

You may have experienced trouble falling asleep after staring at your phone or other digital devices right before bed. Blue light—whether from the sun or from the screens we use—wakes us up and stimulates us. This also means too much blue light exposure late at night from phones, tablets or computer screens can disrupt our ability to fall asleep.

Night mode, or dark mode, is a setting offered on many digital devices to decrease screen brightness and reduce eye strain in the process. Instead of featuring a predominantly white background with black text, the typical dark mode displays a black background with white or colored text or shifts lighter colors more toward pink and red instead of blue. The contrast and colors used in night mode reduce glare and help our eyes adjust more easily to surrounding light, leading to less eye strain and easier, comfortable reading.

When a person is exposed to bright lights at night, their body can react as if it was exposed to sunlight: the brain stops producing melatonin, the sleep hormone, and we feel more awake. The warm colors of night mode don’t confuse the body about what time it is and make it easier to fall asleep than it would be if looking at a device using a regular display mode.

In addition to disrupting the sleep cycle, too bright of a screen in a dark room may cause digital eye strain. Night mode reduces the stark contrast between the screen and dark room, and can reduce some of the symptoms that contribute to the feeling of eye strain.

“There are many important benefits to blue light exposure. Various studies explore how a healthy dose of blue light could help maintain mental performance, decrease nearsightedness in children, etc.,” said Raj K. Maturi MD, an ophthalmologist and clinical spokesperson for the Academy. “Although blue light exposure is important to some degree, it is true that sleep cycles may be disrupted if not handled in moderation at night. Studies show young people are particularly susceptible to blue light affecting sleep. Luckily, our technology has adapted. A simple way to avoid both sleep disruption and eye strain is to turn on night mode on our iPhone or Android devices.”

Nicotine, caffeine and alcohol deserve caution, too. The stimulating effects of nicotine and caffeine take hours to wear off and can interfere with sleep. And even though alcohol might make you feel sleepy at first, it can disrupt sleep later in the night.

Keep your room cool, dark and quiet. Exposure to light in the evenings might make it more challenging to fall asleep. Avoid prolonged use of light-emitting screens just before bedtime. Consider using room-darkening shades, earplugs, a fan or other devices to create an environment that suits your needs.

Vivien Williams: Poor sleep may increase your risk of conditions such as heart disease, obesity, depression, dementia. And it even affects how you look. Dr. Somers offers the following tips: Avoid alcohol and big meals before bed; don"t exercise right before bed; and turn off all screens, including your smartphone, an hour before bed.

Fuethermore, the brain naturally creates the hormone, melatonin, that regulates the sleep-wake cycle. Too much light from video screens at bedtime affect the melatonin production giving the body the impression you aren"t ready for sleep. In addition the screen emits light that suggests to the brain that it is still daytime which contributes to insomnia and sleep deprivation. Holding a device such as a smartphone close to one"s face increases this effect giving the brain the wrong signal as if it"s not time to go to sleep. The best advice is to stop watching TV or using smartphones and other screen devices an hour or two before bedtime to give your brain a rest and the correct signal that it is time for sleep.

Just because blue light isn’t harming your retina doesn’t mean your electronic devices are harmless, or that blue light doesn’t affect your eyes. Because of its wavelength, blue light does disrupt healthy sleep physiology. Blue-light-sensitive cells, known as intrinsically photosensitive retinal ganglion cells, or ipRGCs, play a key role because they tell the brain’s master clock how light it is in the environment. That means when you look at a brightly lit screen, these cells help set your internal clock for daytime-level alertness.

Second, the products that my patients ask about do not block out much blue light. The leading blue-blocking anti-reflective coating, for example, blocks only about 15 percent of what screens emit.

First, turn off your electronic devices before bed. The American Academy of Pediatrics recommends that bedrooms be “screen-free” zones for children, but we should all heed this advice. Outside of the bedroom, when you do look at your screens, lower the brightness.

You also need to take care of the surface of your eyes. We don’t just look at our computer screens; we stare at them. In fact, our blink rate plummets from about 12 blinks a minute to six. As a result, tears evaporate off the eyes, and they don’t accumulate again until we step away from the screen and start blinking. This causes inflammation on the eye’s surface. That’s why your eyes feel dry and tired after a day spent at the computer. I counsel my patients to take two steps to ensure that their eyes stay moist during long computer sessions.

Based on my research, my advice is don’t believe the hype about blue light and don’t waste your money on products you don’t need. Instead, keep screens out of your bedroom and dim them before bedtime and keep your eyes lubricated. And don’t forget to blink.
