When IS the best time to drink coffee? A new study offers some insight.

You there, with the coffee. Yes, you.

Are you going to bed in less than three hours? Or did you just wake up less than three hours ago?

If you answered, "yes" to either question, put the caffeine down and back away slowly.

Don't worry! You can pick it up again later (this is a judgment-free zone). But if you're reading this anywhere close to your bedtime or not too long after waking up, you may want to push pause on the caffeine intake just until you get to the end of this.

I've got news for you about when the best time to drink coffee isn't ... and is.

Big scarf, big coffee, big fun, right? That is, until bedtime. Photo by iStock.

For the first time ever, researchers studied caffeine's effects on our circadian clock, and the results are striking.

Your internal body clock is known as your circadian clock. This clock is present in every aspect of your body. As sleep physiologist Kenneth Wright told NPR, "[your circadian clock] is in your fat cells; it's in your muscle cells. It's in your liver, for example, as well as in your brain."

Doing something that offsets your circadian clock isn't just, like, setting your alarm for p.m. one night by mistake. Messing with your internal sense of time, especially over a prolonged period of time, can have a real negative impact on your health.

Yeah, you might even want to rethink the caffeinated drinks several hours before going to bed. Photo by iStock.

It turns out consuming caffeine at night doesn't just keep you awake. It can completely reset your circadian clock.

Wright and a team of researchers conducted a 49-day sleep study in which participants were given various treatments three hours before bedtime: exposure to bright or dim light and a double espresso or a placebo.

Then, the team checked the participants' saliva for melatonin, a hormone that controls sleep and wake cycles. Melatonin surges through your system at bedtime, helping you drift off to dream land.

For participants who drank the double espresso, their melatonin surge was delayed by an average of 40 minutes.

40 minutes may not sound like much, but it's enough of a shift in your circadian clock that it could make it difficult to get out of bed the next morning and could affect your entire day.

We all have days like this every now and then without doing too much damage, but if every day feels like this, it might be because you're consuming caffeine too close to bedtime. And a consistent lack of sleep can wreak havoc on your immune system and make you more susceptible to colds and viruses.

And hopping aboard the caffeine train first thing in the morning might not be great for your circadian clock either.

Sorry to be the bearer of even more unfortunate research, but ... yeah. Sorry.

I know it's pretty and smells like productivity, but timing is everything. Photo by iStock.

You see, it's all about cortisol. Cortisol gets a bad rap as the "stress hormone" but it's also the hormone that controls your circadian clock. When your body releases it, you feel awake. Your cortisol levels are highest early in the morning.

Buuuuuut caffeine interferes with cortisol production, and if you're guzzling the good stuff early in the morning, your body learns to produce less cortisol and comes to rely on caffeine.

Heavy caffeine intake (think five to six coffees or around 15 Diet Cokes a day) can lead to nervousness, muscle tremors, and insomnia.

So when *is* the best time to drink your coffee?

Because, oh yes, my friends, here's the good news: There are some benefits to drinking caffeinated drinks (especially coffee) in moderation.

The best time to indulge your caffeine habit is mid-morning, when cortisol production is down and, odds are, you're hours away from hitting the sack.

Yes, this post was a long con to use this stock photo. What's good? Photo by iStock.

Mid-morning! The perfect time to enjoy a cup o' joe with a diverse group of multigenerational friends! Or alone while you hide from your co-workers.

Like we said, judgment-free zone.

MIT’s trillion-frames-per-second camera can capture light as it travels

"There's nothing in the universe that looks fast to this camera."

Photographing the path of light.

A new camera developed at MIT can photograph a trillion frames per second.

Compare that with a traditional movie camera which takes a mere 24. This new advancement in photographic technology has given scientists the ability to photograph the movement of the fastest thing in the Universe, light.

The actual event occurred in a nano second, but the camera has the ability to slow it down to twenty seconds.

time, science, frames per second, bounced light

The amazing camera.

 For some perspective, according to New York Times writer, John Markoff, "If a bullet were tracked in the same fashion moving through the same fluid, the resulting movie would last three years."


In the video below, you'll see experimental footage of light photons traveling 600-million-miles-per-hour through water.

It's impossible to directly record light so the camera takes millions of scans to recreate each image. The process has been called femto-photography and according to Andrea Velten, a researcher involved with the project, "There's nothing in the universe that looks fast to this camera."

Her mother doesn't get why she's depressed. So she explains the best way she knows how.

Sabrina Benaim eloquently describes what it's like to be depressed.

Sabrina Benaim's “Explaining My Depression to My Mother."

Sabrina Benaim's “Explaining My Depression to My Mother" is pretty powerful on its own.

But, in it, her mother exhibits some of the most common misconceptions about depression, and I'd like to point out three of them here.

Misconception #1: Depression is triggered by a single event or series of traumatic events.

empathy, human condition, humanity

Depression isn’t just over sleeping.

Most people think depression is triggered by a traumatic event: a loved one dying, a job loss, a national tragedy, some THING. The truth is that depression sometimes just appears out of nowhere. So when you think that a friend or loved one is just in an extended bad mood, reconsider. They could be suffering from depression.

Misconception #2: People with depression are only sad.

family, parents, mom, anxiety

The obligation of anxiety.

Most people who have never experienced depression think depression is just an overwhelming sadness. In reality, depression is a complex set of feelings and physical changes in the body. People who suffer from depression are sad, yes, but they can also be anxious, worried, apathetic, and tense, among other things.

Misconception #3: You can snap out of it.

button poetry, medical condition, biological factors

Making fun plans not wanting to have fun.

The thing with depression is that it's a medical condition that affects your brain chemistry. It has to do with environmental or biological factors first and foremost. Sabrina's mother seems to think that if her daughter would only go through the motions of being happy that then she would become happy. But that's not the case. Depression is a biological illness that leaks into your state of being.

Think of it this way: If you had a cold, could you just “snap out of it"?

No? Exactly.

empathy, misconceptions of depression, mental health

Mom doesn’t understand.

These are only three of the misconceptions about depression. If you know somebody suffering from depression, you should take a look at this video here below to learn the best way to talk to them:

Persuasion expert shares how one word makes people 30% more likely to change their minds

This tactic can immediately get someone on your side.

via LinkedIn Sales Solutions/Unsplash

Here's how to be 30% more persuasive.

Everybody wants to see themselves in a positive light. That’s the key to understanding Jonah Berger’s simple tactic that makes people 30% more likely to do what you ask. Berger is a marketing professor at the Wharton School of the University of Pennsylvania and the bestselling author of “Magic Words: What to Say to Get Your Way.”

Berger explained the technique using a Stanford University study involving preschoolers. The researchers messed up a classroom and made two similar requests to groups of 5-year-olds to help clean up.

One group was asked, "Can you help clean?" The other was asked, “Can you be a helper and clean up?" The kids who were asked if they wanted to be a “helper” were 30% more likely to want to clean the classroom. The children weren’t interested in cleaning but wanted to be known as “helpers.”

Berger calls the reframing of the question as turning actions into identities.

"It comes down to the difference between actions and identities. We all want to see ourselves as smart and competent and intelligent in a variety of different things,” Berger told Big Think. “But rather than describing someone as hardworking, describing them as a hard worker will make that trait seem more persistent and more likely to last. Rather than asking people to lead more, tell them, 'Can you be a leader?' Rather than asking them to innovate, can you ask them to 'Be an innovator'? By turning actions into identities, you can make people a lot more likely to engage in those desired actions.”

Berger says that learning to reframe requests to appeal to people’s identities will make you more persuasive.

“Framing actions as opportunities to claim desired identities will make people more likely to do them,” Berger tells CNBC Make It. “If voting becomes an opportunity to show myself and others that I am a voter, I’m more likely to do it.”

This technique doesn’t just work because people want to see themselves in a positive light. It also works for the opposite. People also want to avoid seeing themselves being portrayed negatively.

“Cheating is bad, but being a cheater is worse. Losing is bad, being a loser is worse,” Berger says.

The same tactic can also be used to persuade ourselves to change our self-concept. Saying you like to cook is one thing, but calling yourself a chef is an identity. “I’m a runner. I’m a straight-A student. We tell little kids, ‘You don’t just read, you’re a reader,’” Berger says. “You do these things because that’s the identity you hold.”

Berger’s work shows how important it is to hone our communication skills. By simply changing one word, we can get people to comply with our requests more effectively. But, as Berger says, words are magic and we have to use thgem skillfully. “We think individual words don’t really matter that much. That’s a mistake,” says Berger. “You could have excellent ideas, but excellent ideas aren’t necessarily going to get people to listen to you.”

A comic about wearing makeup goes from truthful to weird in 4 panels.

A hilariously truthful (and slightly weird) explanation of the "too much makeup" conundrum.

A comic shows the evolution or devolution from with makeup to without.

Even though I don't wear very much makeup, every few days or so SOMEONE...

(friends, family, internet strangers)

...will weigh in on why I "don't need makeup."

Now, I realize this is meant as a compliment, but this comic offers a hilariously truthful (and slightly weird) explanation of the "too much makeup" conundrum.

social norms, social pressure, friendship, self esteem

“Why do you wear so much makeup?"

passive aggressive, ego, confidence, beauty

“See, you look pretty without all that makeup on."

Not everyone is able to turn into a badass lizard when someone asks about their face-painting hobbies. Don't you kinda wish you could? Just to drive this hilarious comic all the way home, here are four reasons why some women* wear makeup:

Four reasons some women* wear makeup:

1. Her cat-eye game is on point.

4. She likes wearing makeup.

appearance, enhancement, creative expression

Happy to be going out and feeling good.

Happy Going Out GIF by Much.

While some people may think putting on makeup is a chore, it can be really fun! For some, makeup is an outlet for creativity and self-expression. For others, it's just a way to feel good about themselves and/or enhance their favorite features.

That's why it feels kinda icky when someone says something along the lines of "You don't need so much makeup!" Now, it's arguable that no one "needs" makeup, but everyone deserves to feel good about the way they look.

For some people, feeling good about their appearance includes wearing makeup. And that's totally OK.

Adorable 'Haka baby' dance offers a sweet window into Maori culture

Stop what you're doing and let this awesomeness wash over you.

@focuswithdan/TikTok

If you've never seen a Maori haka performed, you're missing out.

The Maori are the indigenous peoples of New Zealand, and their language and customs are an integral part of the island nation. One of the most recognizable Maori traditions outside of New Zealand is the haka, a ceremonial dance or challenge usually performed in a group. The haka represents the pride, strength, and unity of a tribe and is characterized by foot-stamping, body slapping, tongue protrusions, and rhythmic chanting.

Haka is performed at weddings as a sign of reverence and respect for the bride and groom and are also frequently seen before sports competitions, such as rugby matches.


The intensity of the haka is the point. It is meant to be a show of strength and elicit a strong response—which makes seeing a tiny toddler learning to do it all the more adorable.

Here's an example of a rugby haka:

Danny Heke, who goes by @focuswithdan on TikTok, shared a video of a baby learning haka and omigosh it is seriously the most adorable thing. When you see most haka, the dancers aren't smiling—their faces are fierce—so this wee one starting off with an infectious grin is just too much. You can see that he's already getting the moves down, facial expressions and all, though.

@focuswithdan When you grow up learning haka! #haka #teachthemyoung #maori #māori #focuswithdan #fyp #foryou #kapahaka ♬ original sound - 𝕱𝖔𝖈𝖚𝖘𝖂𝖎𝖙𝖍𝕯𝖆𝖓

As cute as this video is, it's part of a larger effort by Heke to use his TikTok channel to share and promote Maori culture. His videos cover everything from the Te Reo Maori language to traditional practices to issues of prejudice Maori people face.

Here he briefly goes over the different body parts that make up haka:

This video explains the purerehua, or bullroarer, which is a Maori instrument that is sometimes used to call rains during a drought.

This one shares a demonstration and explanation of the taiaha, a traditional Maori weapon.

@focuswithdan Reply to @shauncalvert Taiaha, one of the most formidable of the Māori Weaponry #taiaha #maori #māori #focuswithdan #fyp #foryou ♬ original sound - 𝕱𝖔𝖈𝖚𝖘𝖂𝖎𝖙𝖍𝕯𝖆𝖓

For another taste of haka, check out this video from a school graduation:

@focuswithdan When your little cuzzy graduates and her school honours her with a haka #maori #māori #haka #focuswithdan #fyp #graduation @its_keshamarley ♬ Te Kura Kaupapa Māori o Ngāti Ruanui - 𝕱𝖔𝖈𝖚𝖘𝖂𝖎𝖙𝖍𝕯𝖆𝖓

Heke even has some fun with the trolls and racists in the comments who try to tell him his culture is dead (what?).

@focuswithdan Credit to you all my AMAZING FOLLOWERS! #focuswithdan #maori #māori #followers #fyp #trolls ♬ original sound - sounds for slomo_bro!

Unfortunately, it's not just ignorant commenters who spew racist bile. A radio interview clip that aired recently called Maori people "genetically predisposed to crime, alcohol, and underperformance," among other terrible things. (The host, a former mayor of Auckland, has been let go for going along with and contributing to the caller's racist narrative.)

@focuswithdan #newzealand radio in 2021 delivering racist commentaries 🤦🏽‍♂️ #māori #maori #focuswithdan #racism DC: @call.me.lettie2.0 ♬ original sound - luna the unicow

That clip highlights why what Heke is sharing is so important. The whole world is enriched when Indigenous people like the Maori have their voices heard and their culture celebrated. The more we learn from each other and our diverse ways of life, the more enjoyable life on Earth will be and the better we'll get at collaborating to confront the challenges we all share.
