🔴Do you really need 8 hours of sleep every night?
Sleep is so important. We need it to live. And when we can't sleep, we're desperate for help.
But lately, our fascination with sleep feels as if it's taken on an urgency. Do a quick internet search for sleep and you'll find a slew of articles about how to make your sleep perfect. New gadgets, fancy alarm clocks, stay away from blue light. There are lots of services, products and advice columns that tell us we're sleeping wrong. Not enough, not quality sleep, wrong position. Even worse, you might find scary messaging claiming that if you're not sleeping right your life is going to be shorter, you're going to get all kinds of diseases.
One of the biggest worries we have about our sleep is that we're not getting enough and that anything less than seven hours a night means that we’re doomed to bad health, everything from high blood pressure to Alzheimer’s disease. But there are two flaws with this kind of messaging. The first flaw is that it's not completely accurate. Seven to eight hours of sleep, while recommended for adults, is just an average. And while messages have to be simplified for health communication to the public, sometimes important nuances get lost. So yes, it's true that not getting enough sleep in the long term is associated with health problems like cardiovascular disease, diabetes and depression. But fixating solely on seven to eight hours ignores the fact that there's a range of sleep that people need. The duration of a good night's sleep can be different for different people. Some adults need eight, but some are just fine on six.
The second flaw with this kind of doomsday messaging is that it can be counterproductive, especially for people who do have trouble sleeping. For instance, in 2019, it was estimated that 21 percent of adults in the US were wearing sleep tracking devices. And that number is probably growing. And I get it. It's fascinating to see how much sleep you've gotten each night and to know what part of your night was spent in deep sleep or dreaming. But having all of that sleep data is causing some people to become obsessed with it, so much so that it’s leading to a condition some call orthosomnia: a preoccupation with the constant need to achieve perfect sleep. And this condition, ironically, is causing more sleep problems.
Now orthosomnia might be an extreme example, but the anxiety of not getting enough sleep is keeping some of us up at night. So here's what some experts are saying. Stop fixating on the number because that can lead to unrealistic expectations of sleep. According to Dr. Colleen Carney, a psychologist and the head of the Ryerson University Sleep Lab, the basic questions you should ask yourself are: Do I feel reasonably well-rested during the day? Do I generally sleep through the night without disturbances? Or, if I wake, do I fall back asleep easily? Can I stay awake through the day without involuntarily falling asleep? If your answers are yes to all three, you probably don't need to worry about your sleep. And if you're struggling with your sleep, instead of buying expensive blue light filters or fancy sleep trackers, try talking with your doctor to make sure there aren't any medical conditions that need to be explored first. Then try evidence-based recommendations laid out by the American Academy of Sleep Medicine. What's really cool is that there's a highly effective therapy called cognitive behavioral therapy for insomnia, or CBT-I, It doesn’t have any medications involved. And it has a really low failure rate.

"In 2019, it was estimated that 21 percent of adults in the US were wearing sleep tracking devices."
Clarification: This statistic was taken from a 2019 Pew Research study that evaluated the number of US adults who wear a smart watch or wearable fitness tracker, which can be used to track sleep among other tracking data, but the study did not specifically look at the number of US adults who wore sleep tracking devices.

🔴A carbon-free future starts with driving less
The number one source of carbon emissions in the United States is coming from transportation. Globally, it's number two. And the majority of that comes from our personal use, our cars and trucks.
How do we consume less energy while meeting the needs that people have of transportation?
[Presented by TED Countdown and The Climate Pledge]
The majority of car trips in the world today are less than five miles. It’s a simple question: Can we get more people to drive less and bike more and scooter more to where they go? The average trip on an e-bike or e-scooter produces less than seven percent carbon emissions of an equivalent car trip. Micro-mobility is dramatically more green than alternatives, and we're working every single day to reduce our own carbon emissions even further.
So what sometimes happens is that a company would say, "What is the dirtiest part of our business? Let's just outsource it. And if we outsource it, we've solved our problems."
But that doesn't actually solve your problem because somebody else is polluting and emitting. If we're going to live up to our own ideals then we need to do the core of what folks have always done: reduce, reuse and recycle.
The early days of micro-mobility, we took a consumer scooter or a consumer e-bike and we put it into a commercial space. And what that meant was that our average scooter lasted a month. Imagine that, every month we need to buy an entire fleet for the world. And that was not green. And it created an enormous amount of shipping cost, manufacturing cost, upstream and ultimately it created problems in terms of end of life of our scooters and e-bikes. And so we found manufacturing partners that can build scooters and e-bikes that last four years, five years, rather than a month.
We also then said, OK, it's not just how long it lasts, it also depends on how many of the parts we can reuse. And so we started to say, let's redesign our entire e-bikes and e-scooters so that if a scooter does break, we can take it apart and reuse many parts of that scooter. We started to use a swappable battery technology. Not only does it increase the life, it also reduces the number of trips we have to take back and forth to actually support our fleet. And we're constantly working to reduce the amount of waste that we actually send to landfill.
As our batteries get to the end of life, they may not have sufficient charge to power an e-bike, but that battery can still power many, many things. We started partnering with a portable speaker maker, and we take that battery that today doesn't have enough juice to power somebody on a scooter and we turn it into the battery for the portable speaker, and it extends and it recycles into that life. A lot of these things wouldn't be part of our direct carbon emissions, but we care about it because the thing that we have to count is the true end to end life cycle of our products.
When I look across all these things, it's not one thing, it's not two things, it's 100 little actions we do. And it starts with understanding and measuring our own environmental impact and challenging ourselves to do better. We have to work at building a future of transportation that is shared, affordable, but most importantly, carbon-free.

🔴4 things all great listeners know
It's easy to tell when someone's not paying attention, but it can be surprisingly tricky to know what truly excellent listening looks like. Behavioral scientists have found that good listening is one of the most important things we can do to improve our relationships, develop our worldview, and potentially even change people's minds. So, what can we do to become better listeners?
At its core, listening in a one-on-one conversation is about taking an interest in another person and making them feel understood. There’s no universally agreed upon definition of high-quality listening, but some recurring features include attentiveness, conveying understanding, and showing a positive intention towards the speaker. This doesn’t mean you can simply go through the motions— researchers have found that merely smiling and nodding at set intervals doesn’t quite work. However, there is something slightly performative about listening in that it’s important to show you’re doing it. So, in addition to actively attending to a speaker’s words, good listeners also use questions and body language that indicate their understanding and their desire to understand.
This might feel awkward at first, and what’s most effective might depend on your relationship with the speaker. But with time and practice you can internalize these basic behaviors. So let’s say a good friend wants to tell you about an issue they’re having with their partner. Before even starting your conversation, remove any distractions in the environment. Turn off the TV, take off your headphones and put your phone away— far away. One study showed that even the visible presence of a phone made conversations feel less intimate and fulfilling to those involved.
Once the conversation begins, one of the most important things you can do is also the most obvious— try not to interrupt. This doesn’t mean you need to stay completely silent. But if you do interject, look for natural pauses to ask open-ended questions that benefit the speaker, not just your curiosity. Questions like “What happened next?” or “How did that make you feel?” confirm that you’re following the story while also helping the speaker dive deeper into their own thoughts. Another great way to show your understanding is by summarizing what you just heard and asking if you’ve missed anything. Summaries like this show the speaker that you're truly trying to understand them rather than just waiting for your turn to talk. Speaking of which, while a good conversation requires back and forth, planning out your response while the speaker is talking is a common way to miss what’s being said. So try to stay present and if you lose focus, don't be shy about asking the speaker to repeat what you missed. This might feel embarrassing, but asking for clarification actually shows that you’re committed to understanding. Finally, don’t be afraid of silence. It’s okay to ask for a moment to formulate your response and taking a beat to think can help speakers reflect on their speech as well.
These might seem like small changes, but together they make a big difference. And when people feel heard, they report more satisfaction, trust, and connection in their relationships. In the workplace, employees who feel heard generally experience less burnout, and perceive the managers who listened to them more favorably. Unfortunately, while it might be easy to listen to some people, it can be hard to muster all this focus and attention if you disagree with or dislike the speaker. But these situations might actually benefit most from your efforts to listen openly. The theory of psychological reactance suggests that trying to force someone to change their mind makes them more likely to defend their point of view. However, recent studies suggest that high-quality listening fosters open-mindedness by creating a non-judgmental and psychologically safe environment.

Of course, truly open-minded listening isn’t about changing people’s minds. Good listening is not the same as agreeing, and conversations don’t have to end with a happy resolution. But even during a disagreement, sometimes being heard is enough to start a deeper conversation.

🔴Can exercise actually "boost" your metabolism?
We often hear that exercise can help with weight loss by speeding up or boosting our metabolism. So is it true? Can we use exercise to control our metabolism?
[Body Stuff with Dr. Jen Gunter]
To answer that question, we have to first dig deeper into what metabolism is. No surprise, metabolism is really complex, and scientists and researchers are still discovering many new things about it. Very simply, metabolism is the set of chemical reactions in every cell of our body that harnesses energy to keep us alive.
So much of what happens in our bodies is metabolism, making new cells is metabolism, growing hair is metabolism, and converting food into energy is metabolism. The sum total energy of all the metabolic processes that occur throughout our body is measured in calories. And surprisingly, exercise is usually a small percentage of our daily calorie burn.
Unless you're a professional athlete, most of our calorie expenditure is accounted for by our basal metabolic rate. All the vital stuff we need to function, like having a heartbeat, growing hair, building cells and even blinking. That stuff takes up a big chunk of our energy. So can we hack this equation in some way? Can we use exercise to speed up our metabolism so we burn more energy? Can we burn even more calories? Not just doing burpees, but while we're growing an eyelash, than before?
The answer is no. First of all, this is a misunderstanding of what fast versus slow metabolism really indicates. There's no clear link between thinner people and fast metabolism, and the same goes for larger people and slow metabolism. In fact, if you look at the absolute numbers, people with larger bodies have faster metabolisms, meaning they burn more calories because larger bodies have more cells, which in turn are doing more to sustain the body.
Now, differences in metabolism between people with similar body sizes do exist, but the difference between fast metabolism and slow metabolism can be about 300 calories. That’s like two apples and a banana.
How fast our metabolism works is mostly genetic and related to body size, but there's also age. Our metabolic rate changes a few times over our lifespan. We start with the metabolic rate of an infant. Then there is a switch when we are toddlers, and then it’s pretty stable during adulthood to age 60, when it changes again.
Researchers evaluated the Hadza, a group of people in Tanzania who live a traditional hunter gatherer lifestyle. And yet, when you control for body size and age, they burn a similar amount of calories a day as an average American adult. It seems that calories out is a pretty fixed number, and it appears that our bodies have limits. If we exercise harder, at first we may expend more energy, but over time, our metabolism will find ways to conserve.
Here's what I'm getting at. The point of our metabolic system is to manage energy, not to manage weight. So if you read an article or hear a so-called expert inviting you to boost your metabolism, remember that’s just marketing speak rooted in a weight loss culture. And it just isn’t true.

🔴The truth about yeast in your body
As an OB-GYN who specializes in vulvovaginal disorders, I hear a lot of myths about vaginal yeast infections, and the one that just won't go away is that they're linked to too much sugar in your diet.
On the surface, the idea sounds plausible. After all, sugar is a food source -- not just for us, but also for yeast and bacteria. So if we eat more sugar, we're feeding the yeast. And there are studies that show yeast infections are more common in people with diabetes, who can have higher levels of sugar in their blood. But the truth is, the sugar consumption-yeast connection is a myth for most, perpetuated both by well-meaning but ill-informed health care professionals as well as purveyors of snake oil -- you know, the ones who want to sell you cleanses, diets and books designed to help you get rid of all the yeast.
The first thing you need to know is that yeast is normally found in the vagina. At some point in a given year, one study estimates that 70 percent of people will have yeast in their vagina, just hanging out in the microbiome and causing no symptoms. And secondly, sugar is normally found in the vagina. After all, that's what also feeds the good bacteria.
It's the overgrowth of this yeast that's already there that produces symptoms and results in what we call a yeast infection.
One theory for the sugar-yeast connection is that the source of the yeast is actually in the gut, and that a high-sugar diet feeds this yeast, which makes it overgrow, and then it gets into the vagina. But there's no credible data to support this. Another theory is that eating more sugar causes sugar levels in the vagina to rise, thus feeding the yeast. But it doesn't. And yes, someone actually studied this. Researchers gave people, some with a history of vaginal yeast infections and others without, a drink containing a lot of sugar or glucose. Their blood and vaginal sugar levels were measured before and after the drink. They found that the sugar levels in the vaginal secretions didn't change for either group.
But what about diabetes? Now we know diabetes is associated with an increased risk of vaginal yeast infections, but the actual reason why isn't known. While very elevated glucose levels might be part of it, it seems the immune system and other factors may also be playing a role. There is a newer class of diabetes medications that causes people to dump a lot of sugar into their urine as a way to lower blood sugar. The massive amounts of sugar in the urine can cause yeast infections on the vulva as the vulva is being bathed in levels of sugar it didn't evolve to handle. But unless you have diabetes, there is no link between eating sugar and yeast infections.
So ignore the so-called influencers. It’s fine to enjoy a slice of cake now and then. And definitely skip the cleanses.

And there are studies that show yeast infections are more common in people with diabetes, who can have higher levels of sugar in their blood. But the truth is, the sugar consumption-yeast connection is a myth for most, perpetuated both by well-meaning but ill-informed health care professionals as well as purveyors of snake oil -- you know, the ones who want to sell you cleanses, diets and books designed to help you get rid of all the yeast.
The first thing you need to know is that yeast is normally found in the vagina. At some point in a given year, one study estimates that 70 percent of people will have yeast in their vagina, just hanging out in the microbiome and causing no symptoms. And secondly, sugar is normally found in the vagina. After all, that's what also feeds the good bacteria.
It's the overgrowth of this yeast that's already there that produces symptoms and results in what we call a yeast infection.
One theory for the sugar-yeast connection is that the source of the yeast is actually in the gut, and that a high-sugar diet feeds this yeast, which makes it overgrow, and then it gets into the vagina. But there's no credible data to support this. Another theory is that eating more sugar causes sugar levels in the vagina to rise, thus feeding the yeast. But it doesn't. And yes, someone actually studied this. Researchers gave people, some with a history of vaginal yeast infections and others without, a drink containing a lot of sugar or glucose. Their blood and vaginal sugar levels were measured before and after the drink. They found that the sugar levels in the vaginal secretions didn't change for either group.
But what about diabetes? Now we know diabetes is associated with an increased risk of vaginal yeast infections, but the actual reason why isn't known. While very elevated glucose levels might be part of it, it seems the immune system and other factors may also be playing a role. There is a newer class of diabetes medications that causes people to dump a lot of sugar into their urine as a way to lower blood sugar. The massive amounts of sugar in the urine can cause yeast infections on the vulva as the vulva is being bathed in levels of sugar it didn't evolve to handle. But unless you have diabetes, there is no link between eating sugar and yeast infections.
So ignore the so-called influencers. It’s fine to enjoy a slice of cake now and then. And definitely skip the cleanses.

🔴How do we create a better economy?
What does it mean for a country to have a healthy economy? What does a healthy economy even look like? Does it look like this? What about like this? Economist Kate Raworth shared a pretty interesting answer to this question on the TED Interview podcast. And it challenges an idea that most economists take for granted.
We live— particularly in the West, particularly in the last 150 years— in a society that has a very strong belief that growth is the sign of progress. And to a certain extent, it’s true. We love to see our kids grow. We love to see nature growing in spring. Growth is a wonderful, healthy phase of life.
But in our economies, it’s like we’ve turned to Peter Pan economics— the economy that never wanted to grow up. It wanted to grow and grow and grow forever. And it becomes this permanent phase.
But we already know, in our own bodies, in our own lives, that there’s another side to this metaphor of growth that we love so much. If I told you, my friend had gone to the doctor, and the doctor told her she had a growth, that already feels completely different. Because in the space of our own bodies, we know that when something tries to grow endlessly within this healthy, dynamic living whole, it is a threat to the health of the whole, and we do everything we can to stop it.
But when we step into our economies, for some reason, we think that endless growth is progress. And we are now running into severe problems because we are addicted to endless growth
Simon Kuznets, he was asked in the 1930s by US Congress to come up, for the first time, with a single number to measure the output of the economy. America could say we produced so many tons of steel and so many bags of grain— but can we add it all together? So they commissioned him to do this and he said, “Yes, I can. I can add it all together in one number.” National income, what we now know as GDP— but he gave it with a caveat. He said the welfare of a nation can scarcely be known from this number, don’t mix it up with welfare, right? Because it tells us nothing about the unpaid caring work of parents, tells us nothing about the value that’s created in communities, because that’s not priced, and it’s a measure of the flow of economic value. It tells us nothing about the living world, the forests, the mines that get run down in order to create this value. But the convenience, the temptation, of this single number was so great that politicians sort of tucked it in their armpit and carried right on. And we ended up in a horse race of pursuing GDP growth.
The dream is that GDP can keep on increasing, we can have increasing financial returns, but that we can decouple from using Earth’s resources. We can use less carbon and less metals, and minerals and plastics, and we can use less of the Earth’s land surface, and separate these two: ever rising GDP and falling resource use. It’s a fabulous dream; would that it would be true.
We are at a time of climate emergency, of ecosystem collapse. We need to radically reduce our use of Earth’s resources, and we're nowhere close to that.
So I offer it as a compass for 21st century prosperity. And this compass, silly though it sounds, it looks like a doughnut with the hole in the middle.
So imagine from the center of it, humanity’s use of Earth’s resources radiating out from the middle of that picture. So in the hole, in the middle of the doughnut, that is the place where people don’t have enough resources to meet the essentials of life. It’s where people don’t have enough food or health care, or education or housing or gender equality or political voice or access to energy. And we want to leave nobody in that hole. We want to get everybody over a social foundation of well-being, so all people on this planet can lead lives of dignity and opportunity and community. And in low income countries, it absolutely makes sense, yes, let’s see the economy grow in ways that invest in health and education and transport for all. That was a very 20th century project. We're in the 21st century.

We have Earth system scientists who started looking at the impact we were having on the climate, and the loss of soils and acid rain, and the hole in the ozone layer, and the collapse of species. And they said, hang on. We’ve been ignoring our planet. In the growing to meet human needs, we have ignored the fact that we are deeply dependent on this delicately balanced living planet. It’s the only one we know of out there. And when we use Earth’s resources in such a way that we begin to push ourselves beyond the living capacities of this planet, we are literally undermining the life supporting systems on which we depend.
So, hang on, just as there’s an inner limit of resource use, and we call out poverty and deprivation, there’s an outer limit of humanity’s resource use. That’s ecological degradation. And we are breaking down this planet on which we depend. So there you get the doughnut, you get the inside, which is leave nobody behind in the hole. But don’t overshoot the outer ring either. And so the shape of progress is fundamentally changed. It’s no longer this ever rising line exponential growth, that we hear about in the financial news all the time. It’s balance.
To me, a source of real hope is that we deeply understand this at the level of our body. You go to the doctor, the doctor will say, have enough food, but not too much, enough water, oxygen, exercise, sleep, anything you like— have enough, but not too much. Our health lies in balance. And if we can take that metaphor from the human body to the planetary body, we give ourselves a cracking chance of understanding the deep interdependence of our world.

🔴The best way to apologize
Over the years, people have come up with some truly awful apologies. From classic non-apologies to evasive excuses, and flimsy corporate promises, it’s all too easy to give a bad apology. But researchers have found that good apologies generally share certain elements and thoughtfully considering these factors can help you make amends in a wide variety of situations.
Since public apologies have their own unique complications, we’re going to focus on some person-to-person examples. So, picture this: your new office has free ice cream sandwiches in the communal fridge— or at least that’s what you thought. But on Friday, when you’re helping your co-worker Terence set up another colleague's birthday party, he finds that half the ice cream he bought for the celebration is gone. While this is obviously an embarrassing accident, coming forward and apologizing is still the right thing to do. Understanding and accepting responsibility for your actions is what some researchers call the “centerpiece of an apology.” But it’s okay if this feels difficult and vulnerable— it’s supposed to be! The costly nature of apologies is part of what makes them meaningful. So while you might be tempted to defend your actions as accidental, it’s important to remember that a good apology isn’t about making you feel better. It’s about seeking to understand the perspective of the wronged party and repair the damage to your relationship. This means that while clarifying your intentions non-defensively can be helpful, your mistake being an accident shouldn’t absolve you from offering a sincere apology.
But what if your mistake wasn’t an accident? Consider this: you promised your friend Marie that you’ll attend her championship football match. But another friend just called to offer you an extra ticket for your favorite musician's farewell tour. You know this is a once-in-a-lifetime chance, and you can’t pass it up. Plus, you figure Marie wouldn’t mind if you miss the game— she always has plenty of fans supporting her. But the next day, Marie tells you she was really hurt when she didn’t see you in the crowd.
You feel terrible for upsetting her and genuinely want to apologize. But while you regret hurting Marie, you’re not actually sure if you made the wrong choice. So how can you reach beyond that terrible non-apology, “I’m sorry YOU feel this way”? In situations like this, it can be easy to focus on rationalizing your actions when you should be working to understand the other person’s perspective. Consider asking Marie how you made them feel to better understand your offense. In this case, Marie might explain that she was disappointed you broke your promise, and she was really counting on your support. This kind of clarity can help you recognize your wrongdoing and honestly accept how your actions caused harm. Then you can frame your apology around addressing her concerns, perhaps by admitting that it was wrong of you to break your promise, and you're sorry you weren't there for her.
Clearly acknowledging wrongdoing indicates that you know exactly how you messed up, and it can give Marie faith that you’ll behave differently moving forward. But it’s always helpful to indicate exactly how you’ll change and what you’ll do to repair the damage caused by your offense. Researchers call this the “offer of repair,” and it's often rated as one of the most critical parts of an apology. In some cases, these gestures are straightforward, like offering to replace the ice cream you eat. However, with less tangible transgressions, this might need to be more symbolic, like expressing your love and respect for someone you wronged. One common offer of repair is a verbal commitment not to make the same mistake again, but promising to do better only works if you actually do better.
