Designers sparked a hot debate by vilifying 'the big light.' Here's what the science says.
People have surprisingly big feelings about lighting…

Lighting can actually make a big difference in our mood.
My family has an ongoing debate about a specific lamp in our house. We have five lamps in our living room, but one of them only gets used half as often as the others because half of the family hates the light that lamp gives off and half of us are bothered by the lack of light in that corner of the room when it's off. Lamp on, lamp off. Lamp on, lamp off. Every night.
But there's one thing we all agree on: We never EVER turn on "the big light."
The big light is the overhead light in the center of the ceiling. If anyone ever turns on the big light, everyone else says, "Ewww! Turn it off!" It immediately evokes a visceral disgust in all of us, which is why we are tolerant of one another's feelings about the lamp-in-dispute. We may not agree on that particular lamp's effect, but we all fundamentally understand that lighting matters.
Apparently, we're not the only ones.
TikTok designers Josh and Matt shared a video explaining why the big light needs to be banned, and it's racked up a whopping 35 million views and 7.5 million likes.
"We all have big light friends who need to hear this," reads the caption. I have never felt so seen. Watch:
@joshandmattdesign We all have big light friends who need to hear this 🤭💡 #interiordesign #lighting #biglight
But what's interesting is that in the comments, people's opinions on the big light are split. Some of my fellow #TeamLamp members shared how the big light makes them feel:
"I’m physically allergic to the big light ESPECIALLY at night."
"The big bright light gives me anxiety istg."
"Literally me at all times I cannot stand the big light anywhere it overwhelms and irritates me @🌙."
"I am the worst version of myself when the big light is on."
"The big light is for when i’m cleaning my room and that’s it."
"Big light it's only for cleaning or looking for something important."
"The big light feels like when they turn on the lights in the club and you’re just embarrassingly forced to go home."
But some people are totally #TeamBigLight, eschewing the soft, ambient lighting that #TeamLamp lives for:
"Using low ambient lighting makes my brain feel like idk muddy or something, I hate it."
"I feel like I can’t see…like I can’t wear sunglasses because if my vision is distorted in any way I get so anxious."
"I love and exclusively use the big light. I wanna seeeee not have a bunch of different headache points 😂😂😂."
"I need the big light on when I’m cooking or I simply cannot cook."
"As someone who grew up with dim warm lights & dark New England winters, I like the big white lights. Makes me feel like I can actually see for once 😅."
"Sometimes ambient lighting actually triggers my anxiety (no clue why lol) so big light just gets a warm bulb for me. I like seeing stuff clearly."
So the big light makes some people anxious and not using the big light makes other people anxious. Huh.
That last commenter hit on something that others mentioned also. Overhead lighting is often cool (bluish-hued) lighting while lamps are warm (yellowish-hued) lighting, but you can buy warmer light bulbs to put into overhead lights to make them less harsh and hospitally. That doesn't fix all of the big light issues, but does help reduce the "this lighting makes me feel stabby" effect.
So what does science say about all of this? Surely if people feel this strongly about something, there's a solid reason behind it, right?
Environmental psychologist Sally Augustin, PhD, writes that lighting does impact how we feel and how we function. Warm lighting is conducive to creative work and socializing, whereas cool lighting can help us concentrate and be more productive. "Do your taxes in cool light, write poetry and hang out with friends in warmer light," she says.
However, she also adds that putting cooler lights in overhead fixtures and warm lights in lamps mimicks how light works in nature. "Warmer light generally is found lower in the natural world, at the horizon during sunrise and sunset, for example, while the sun overhead at noon is cool light," she writes.
That may be true, but for those of us who can't stand the big light, there's nothing about it that feels natural. And there's no question that it's unflattering. That's even true in nature—ask any photographer if they want to take someone's portrait outside at noon and they'll laugh in your face.
This debate does make one wonder if #TeamLamp tends to be more creative and laid back by nature and #TeamBigLight tends to be more focused and productive, and that's why some prefer one kind of light over the other. Or maybe it really is just about being able to see clearly or not.
At any rate, people clearly have strong feelings about this. Isn't that fascinating? Are there any unicorns out there who don't give any thought to lighting at all? (If so, how do you live like that?!?)
There's a reason why some people can perfectly copy accents, and others can't
Turns out, there's a neurodivergent link.

Have you ever had that friend who goes on vacation for four days to London and comes back with a full-on Queen's English posh accent? "Oooh I left my brolly in the loo," they say, and you respond, "But you're from Colorado!" Well, there are reasons they (and many of us) do that, and usually it's on a pretty subconscious level.
It's called "accent mirroring," and it's actually quite common with people who are neurodivergent, particularly those with ADHD (Attention Deficit Hyperactivity Disorder). According Neurolaunch, the self-described "Free Mental Health Library," "Accent mirroring, also known as accent adaptation or phonetic convergence, is the tendency to unconsciously adopt the accent or speech patterns of those around us. This linguistic chameleon effect is not unique to individuals with ADHD, but it appears to be more pronounced and frequent in this population."
Essentially, when people have conversations, we're constantly "scanning" for information—not just the words we're absorbing, but the inflection and tone. "When we hear an accent, our brains automatically analyze and categorize the phonetic features, prosody, and intonation patterns," writes Neurolaunch. For most, this does result in copying the accent of the person with whom we're speaking. But those with ADHD might be more sensitive to auditory cues. This, "coupled with a reduced ability to filter out or inhibit the impulse to mimic…could potentially explain the increased tendency for accent mirroring."
While the article explains further research is needed, they distinctly state that, "Accent mirroring in individuals with ADHD often manifests as an unconscious mimicry of accents in social situations. This can range from subtle shifts in pronunciation to more noticeable changes in intonation and speech rhythm. For example, a person with ADHD might find themselves unconsciously adopting a Southern drawl when conversing with someone from Texas, even if they’ve never lived in the South themselves."
People are having their say online. On the subreddit r/ADHDWomen, a thread began: "Taking on accents is an ADHD thing?" The OP shares, "My whole life, I've picked up accents. I, myself, never noticed, but everyone around me would be like, 'Why are you talking like that??' It could be after I watched a show or movie with an accent or after I've traveled somewhere with a different accent than my 'normal.'
They continue, "Apparently, I pick it up fast, but it fades out slowly. Today... I'm scrolling Instagram, I watch a reel from a comedian couple (Darcy and Jeremy. IYKYK) about how Darcy (ADHD) picks up accents everywhere they go. It's called ADHD Mirroring??? And it's another way of masking."
(The OP is referring to Darcy Michaels and his husband Jeremy Baer, who are both touring comedians based in Canada.)
Hundreds of people on the Reddit thread alone seem to relate. One comments, "Omfg I've done this my whole life; I'll even pick up on the pauses/spaces when I'm talking to someone who is ESL—but English is my first language lol."
Sometimes, it can be a real issue for those around the chameleon. "I accidentally mimicked a waitress's weird laugh one time. As soon as she was out of earshot, my family started to reprimand me, but I was already like 'oh my god I don’t know why I did that, I feel so bad.'"
Many commenters on TikTok were shocked to find out this can be a sign of ADHD. One jokes, "Omg, yes, at a store the cashier was talking to me and she was French. She's like 'Oh are you French too? No, I'm not lol. I'm very east coast Canada."
And some people just embrace it and make it work for them. "I mirror their words or phrase! I’m 30. I realized I start calling everyone sweetie cause my manager does & I work at coffee shop."
