Does happiness have a scent? Dr Laurie has been trying to remove the bad smells in her life and bring in more fragrances that enhance her wellbeing. But she's noticed that some of the smells that bring her joy can be a little weird - like musty books and rotting seaweed. 

So what's going on in our noses and brains? Laurie turned to neuroscientist Dr Rachel Herz (author of The Scent of Desire) to explain why we respond to certain smells and how we can use scent to reduce stress, boost our happiness, make us perform better and even to find the perfect mate.

Busy scientist Adam Aron had too much on his plate to think deeply about climate change - until he read a scary report about what lay in store for the planet if no one acted to cut greenhouse gases. 

So Adam did more and more to fight climate change, until activism became his full time occupation. And the move made him happier and more content. We can't all give up our normal lives to stop global heating - but even making small contributions to the cause can make us feel more connected, more fulfilled and happier.

We often think of fighting climate change as a drain on our happiness - it'll mean sacrificing the things we love, like air travel or eating hamburgers. But researchers Jiaying Zhao and Liz Dunn have pioneered the idea of "Happy Climate" that shows us ways in which doing good for the planet can make us feel great.   

Changing how we fly, drive, shop and eat in very small ways can make us enjoy our travel, our friends, our wardrobes and, yes, even our steaks, more than ever before.

Humans are great at reacting to mortal danger... but only sometimes. Unfortunately, some risks to our safety and wellbeing don't set off alarm bells in our brains. Climate change falls into that category. Why is that?

Harvard psychologist Dan Gilbert explains how some dangers trigger us, and some don't. In discussion with Dr Laurie Santos, he also outlines ways in which we can be made to care more about threats to the planet and maybe react to them in more positive, happiness-inducing ways.

Time off work is vital for your happiness. So what would you do if you couldn't take the same rest day as your family and friends? Would you quit your job? What if it was the murderous dictator Stalin giving you the order?

The Soviet Union wanted its factories to run every day, so workers were stopped from taking the same day off - killing the weekend as we know it. In a crossover between The Happiness Lab and Cautionary Tales, Dr Laurie Santos and Tim Harford discuss the pros and cons of everyone downing tools together and why holidays matter so very much.

Enjoy this episode of another show you might like: the Build the Life You Want Super Soul Podcast. Oprah and Arthur Brooks offer listeners a better understanding of the science behind happiness and why Arthur says, “Happiness is not a destination, happiness is a direction.” Together, they take questions from people across the country who have read Build the Life You Want and are curious how to apply topics from the book to their own lives. They discuss the “The Four Pillars of Happiness: Faith, Family, Friends and Work that Serves” as well as the power of metacognition which Oprah calls “one of the biggest contributions to people getting happier.” Arthur Brooks explains how using “emotional caffeine” can lead to greater happiness and how having “a better storage of emotions” can block anxiety and depression.

Have we created a culture where young people prioritize good grades, social media likes and constant hustling over the important wellbeing pillars of sleep, friendships and free time?

Dr Laurie Santos joins the US Surgeon General on his podcast House Calls with Dr. Vivek Murthy to ask how we got here and what Gen Z can do to get out of this happiness crisis.

For our ancient ancestors food was just another thing they needed to survive - like sleep, shelter or warmth. But in the modern world, food has become a source of anxiety. Do we eat too much, or too little? And are we feeding ourself the "wrong" things?

Dr Laurie Santos has plenty of thoughts on our complicated relationship with eating and shared them on a recent episode of the PRX podcast Food, We Need to Talk. The show turned out great, so we thought we'd give you the chance to hear Laurie's chat with the hosts Juna Gjata and Dr. Eddie Phillips. 

Just like The Happiness Lab, Food, We Need to Talk relies on the latest science to tackle issues like body image, nutrition, exercise and addiction. You can listen to other episodes of Food, We Need to Talk wherever you get your podcasts.

Laurie's former student and friend, Dr. Maya Shankar, has a Pushkin podcast we love called A Slight Change of Plans. If you like The Happiness Lab, then this show is right up your alley. In this episode, Maya and author Michael Pollan discuss the fascinating science of psychedelics and how they have the power to transform our minds and improve our mental health. You’ll also get a glimpse into Michael’s personal experience with psychedelic trips and how they unlocked a singular kind of joy within him. Plus, you'll hear him try and convince scaredy-cat Maya to give them a try. 

You can hear more from A Slight Change of Plans wherever you get your podcasts.

YOU can boost your happiness and transform the lives of people in one African village with a cash gift by going to givedirectly.org/happiness

Giving money to others makes you happier than spending the same cash on yourself. That's been proved by science. But new research also shows that giving people in need cold hard cash is an amazing way to help them improve their lives. We explore why trusting people to help themselves is a cheaper and more effective way to solve poverty - and hear about Kibobo in Rwanda, where any money you donate will have a huge impact.

Former British politician Rory Stewart used to manage billions of dollars in aid money - and like other international donors thought poor people needed to be told what to do with charitable gifts. He was shocked how effective no-strings-attached cash turned out to be, and now promotes "giving directly". He was also surprised how good giving away even small amounts of money made him feel.
