Harvard scientists ran a simple test. They put adults under blue light for 6 hours one night, then under green light at the same brightness the next. Blue light pushed their bedtimes back by 3 hours. Green pushed them back by 1.5. And in kids, the same lights hit about twice as hard.

The reason comes down to a tiny patch of cells at the back of every human eye. These cells have one job. They tell your brain whether it is day or night. They wake up most when light hits a very specific shade of blue, the same shade phone screens and modern bulbs are loaded with. When those cells fire after dark, the brain stops making melatonin, the chemical that pulls you toward sleep.

Red light barely sets off those cells at all. A 2025 study from the University of Zaragoza put people under red lamps and blue lamps for three hours at night. Under blue, their melatonin stayed scraped to the floor. Under red, it climbed back up to more than three times higher. Same brightness. The color did all the work.

Children get this worse than adults. Two reasons. Their pupils are bigger, so more light gets in. And the lens inside a kid's eye is still glass-clear, where adult lenses slowly yellow with age and filter blue out naturally. A 10-year-old's body clock is roughly twice as sensitive to evening light as a 45-year-old's. A bedside lamp that feels harmless to a parent can be wrecking a kid's sleep clock at the same time.

Then there is the lag. Once the brain catches a dose of blue light, the wake-up signal it sends out keeps echoing for 3 to 4 hours after the lights go off. So a kid on an iPad at 9pm can still be wired at midnight even if you took the iPad away at 9:01.

Modern LED bulbs and screens are tuned to roughly 6500 Kelvin. That is sunlight at noon. Old incandescent bulbs sit around 2700, mostly red and yellow with almost nothing in the blue range. To a human eye, a red-lit room is just about as close to no light at all as you can get. The brain reads it as nighttime.

The fix is boring. Use warm bulbs at 2700 Kelvin or lower in any room a kid spends evenings in, switch off phones and tablets two hours before bed, and if a night light is needed for bathroom trips, make it red or amber. The science was pinned down to the exact color of light back in 2001.

This is probably going to tick some people off, and I hope it does. But I’m going to keep on sharing it and saying it. And once again, I am not a Swiftie, but I am a human being, a Dad AND, a Monstrous Football fan.
I am extremely disappointed in so many of you who think that "not being a fan" of someone means you're entitled to shit all over them.
I want to remind you of something.
Your children are watching you complain about Taylor Swift sitting at a football game, being happy, and cheering for a man she loves in what appears to be a very loving, respectful relationship.
Your Children are watching you judge a woman for literally just EXISTING and taking up space happily.
And you know what? Ms. Swift has won 324 awards? How many do you have?
She brought $5 BILLION dollars in consumer spending and boosted the U. S. economy so significantly, that leaders from other countries actually beg for her to play there?
Did you know that there are over 20 college courses about her skills as an artist, lyricist, and musician - including at places like Harvard, Stanford & UC Berkeley?
Did you know that Taylor Swift quietly donates mass amounts of money to local food banks in every city she performs in?
AND DID YOU KNOW …
That Taylor Swift was sexually assaulted by a radio DJ, and she got him fired? When he sued HER for over $3 million for defamation, she counter sued for a symbolic $1 in a court case that took 2 YEARS for her to win. And, she did that just to show women that fighting for what's right has no price tag & to never be silent in the face of oppression.
WELL IF YOU DON’T CARE BY NOW, YOU SHOULD.
Because your daughters, nieces, and your nephews are watching you run your mouth. And they are seeing the world hate a woman who does so much good, simply because she exists in their line of sight.
DO BETTER PEOPLE.
Teach your boys to respect women. Teach your girls that as women - they are ALLOWED to take up space.
Fix it. Become aware of your words. Because we all have the ability and the obligation to fight for the future of our children with simple moments. And we need to consciously choose to be better for them.

There is a bit missing in the clip. John was returning from an interview for a job, which he thought went really badly, that was when first met that girl. He got home, was told he had actually got the job, a moment of sheer joy, his first adult job. He was sent out to get a “Chinese feast”, on his way back he was beaten to a pulp, waking in a hospital bed.

Why is this so relevant? The BAFTAs, just like gaining that job, should have been a moment of huge joy, instead his moment has been ruined by feckless ignorant idiots who care more for themselves than they do him!
