I will be the first person to accept, I would like to scroll in the evening. I try my best to follow a comfortable screen-free night routine, but some nights are one over me.
Fortunately, I sleep on one of this year’s top-rated mattresses and get a lot of fresh air and movement during the day, so this evening light exposure does not completely ruin my sleep. However, I am keen on the effect of blue lights on the quality of my overall sleep.
Online advice around blue light is conflicting. Some sources say that it is sure to ruin your sleep, while others say that it is not so bad.
Therefore, I dug in studies and Dr. Michael Gradiser, Sleep Science’s major sleep cycle, and insomnia and sleeping the therapist Dr. Anna Joyce To set the record straight. Here both these experts want you to learn about blue light and sleep …
What is blue light?
Blue light is part of the visible light spectrum and is about one third of all light that we see as humans.
This type of light affects vigilance, hormone production and sleep cycle.
Blue light comes naturally from the Sun, we consume the biggest source of blue light, but it can also come from artificial sources such as smartphone screen, television and fluorescent and LED lights.
How does a blue light effect sleep?
Bright light, ie blue light, interfere with the circadian rhythm by pressing the production of sleep-ignition hormone melatonin.
When the brain identifies light, it sends a signal to the body that it is asking to be cautious rather than sleep. So, in theory, in the evening, the onset of sleep in contact with blue light should be delayed.
On the other hand, it helps us to come in the morning. Therefore, the first thing to expose yourself to the light of natural day is that it is an important tip to fight and get up in the morning and raise them, which in turn helps us in better sleep at night.
The common belief is blue light is bad news for sleep – and with the right reason. A 2022 systematic review Studies examining the effects of blue light on the conclusion of sleep, performance and goodness may have negative effects such as sleep quality and decrease in sleep duration by Swiss researchers.
However, by recent research Conversation Suggestions that blue lights are not as bad for sleep as we are leading to trust before.
Sleep experts from Sweden, Australia and Israel found the risk of blue light delayed in just 2.7 minutes – hardly enough.
Can blue light really ruin sleep?
Dr. Gradeiser and Dr. Experts, including Joyce, now agree that although the light melatonin from the screen delays release, it makes only a minimum difference. Light from screen is not bright enough to affect just sleeping patterns.
“To make a person’s sleep time meaningfully for blue light, the light source must be at least ten times brighter than being emitted from the phone, tablet or other devices,” Dr. Gradeiser says.
Instead, it is our cultural disability in closing the screen at bedtime, as we are ignoring social media feeds, which affects our sleep, especially how long we sleep.
Dr. Research from gradeiser Shows that the biggest sleep disintegration is delaying gold due to the use of screen instead of light from the screen.
“Don’t be afraid to use the screen before the bed – just give them time wisely,” they say. “While blue lights from the phone are often blamed, my research has shown that the greatest dissolution is really delaying sleeping, not the content from light or screen itself.”
“Watching TV or listening to podcast as a wind-down routine can be completely cured, especially if it helps reduce the night time, unless it cuts the number of hours you receive.”

Be selective on what you consume
When I fall into the trap of sticking to my phone in the evening, it is definitely difficult to switch.

Instead I am thinking about a couple’s breakup, which I have never got, is considering if I really need that new organization or to dream of that holiday destination which was designed to look right in the video of 30 seconds.
Dr. Joyce explains, “The problem is that we usually use screens to attach and consume the work, such as work, reading news, or scrolling social media; everything that stimulates us and affects our mood,” Dr. Joyce explains.
“The brain requires time for the bottom air to sleep so that some infection is helpful between the use of the screen and the sleeping time.”
Similarly, Dr. Gradisers recommend watching TV for podcast or your bedtime instead of scrolling.
“There is an inactive tool compared to TV phones. Many people sleep well after watching TV, with some sisters, while it is on,” they say.
Be disciplined at bedtime
There is no serious disadvantage in using the screen as part of one night wind-down routine-television programs or films are a mainstay in the evening of many people.
But, as Dr. Gradeiser’s research shows, you need to be disciplined at your screen shut off time before bed to ensure that it does not eat significantly.
This means that when the sleeping rolls around the time, the Ticketkok app is self-control to flick the app or shut down Netflix instead of ‘Play Next Episode’.
A 2024 study Researchers at the University of Otago have concluded that we should keep the evening out of the screen for better sleep instead of cutting the evening.
This applies a cut off point to the screen – that is, use them on the couch, but keep them down after going to bed.
