Stop texting the people you love (new oxytocin research!)š©š½āš¬
Leslie Seltzer and her colleagues discovered the importance of hearing voices in order to release oxytocin š
We can also increase our oxytocin through contributing to others, listening carefully, making eye contact, physically connecting and by complimenting one another š¤
I have written all about the latest science and how you can optimise your oxytocin in my new book - The DOSE Effect. You can secure your copy right now by pre-ordering at the link on my page! š
Georgia and I are sending you all a ton of oxytocin today, have a great time connecting with the people you love ā¤ļø

Our new dopamine detox experimentā¦
For us weāre always just trying to spend a bit less time behind screensā¦š±
Itās not that screens are all bad itās just that our brains donāt wanna always be consuming content⦠ā
Our brains designed to rest by being in nature, by connecting, by laughingā¦š³
This experiment showed us how much happier our brains can become from less stimulation⦠š§
Definitely give it a shot for yourself, even if it just for one evening⦠šŗ
Thereās a place beyond the boredom where you feel so good⦠āØ
Let us know how you get on and whether itās easy or hard⦠š¤
And send this to someone you could try it with⦠ā”ļø

We did it!! Sunday Time Bestseller šš
5 years ago I started massively changing my lifestyle to fix my mental health.
4 years ago I started sharing the method I used with you all on here.
That method involved learning exactly how each of my key brain chemicals was impacted how I felt and then with that understanding, learning the best way to rebalance them.
Seeing this simple idea now working for so many of you is beautiful to witness.
Iām beyond grateful to all of you that have supported DOSE and me, thank you.
Hereās to many more years of sharing the best way to build a purposeful, calm and healthy life ā¤ļø
A hugeee thank you to @harpercollins @hqstories @mslisamilton @bevjamesmanagement @bev_james @tomtomwright for making this possible, you guys are legends š

Scientists measured serotonin levels when walking in a forest.
Dr Qing Li took overworked individuals into Akasawa Forest in Japan and saw:
1. Increased serotonin levels = mood improvedāØ2. Raised vigour scores = felt way more aliveāØ3. Lowered fatigue scores = energy restored
Nature holds unlimited antidepressant effects.
Whether itās warm and sunny or raining and cold, every week should include a prolonged period of time connecting with old trees.
Whatās your favourite natural antidepressant?

My no.1 focus for the future is conversational skills:
I believe your ability to have good conversations, in your work and with the people you love, will be the number one skill of the future.
The ability to think deeply, pay attention, recall memories, ask interesting questions, and show interest in others is what I think you should focus on.
What are you focusing on to help yourself build a brighter future?

Fun fact. Your neurons just did what you just learned. You didnāt know how neurons connected, and now you do.
Your brain is unbelievably capable of change and learning because of neuroplasticity.
Here are my favourite ways to maximise it as a neuroscientist:
1. Learn something hard. A language, an instrument, a new skill.
2. Walk and picture your future. Movement and visualisation is an unreal combo.
3. Maximise your sleep. Itās when the brain locks in what you learned.
4. Seek new experiences. New routes, new places, new people.
5. Embrace boredom. Your brain needs rest to process what you learn.

Watch them find each other.
In our uncertain world, itās so important to practise seeing the good as best you can.
The more you practise, the more youāll see.

10 tricks to win at life, but the 11th is where it all starts.
These are all clever ways to push yourself to live a healthier life.
But they also come with outside pressure from somebody else.
While the love for who you deserve to be, doesnāt need anyone but you.

A researcher put electrodes on childrenās heads and sent them on a 20-minute walk or left them sitting down. The scans werenāt close.
Dr. Charles Hillmanās team at the University of Illinois found that the walking group showed a measurable spike in a specific brain signal linked to attention and focus - the kind of neural activity linked to better test performance immediately afterward. No caffeine, no supplements. Just movement.
Itās the kind of finding Nietzsche, one of the most influential western philosophers, noticed without needing an EEG cap. He wrote his entire final book almost exclusively on foot, walking six to eight hours some days, and left behind a really unique piece of advice: sit as little as possible, and donāt trust an idea that wasnāt born in the open air, moving.
Your brain isnāt broken when it feels foggy. It might just be sitting down.

Worst dopamine ā”ļø Best dopamine
Iāve struggled like crazy with dopamine addictions.āØāØThe only thing that saved me was understanding that my brain is always going to crave dopamine.āØāØSo if I donāt give it the good kind, Iām going to get lost in the bad kind.
Basic things like learning to take big slow deep breaths when I was quitting cigarettes. Or reading in bed instead of scrolling made a massive difference.āØāØThis simple idea of replacing bad dopamine with good dopamine changed the course of my life and can do the same for yours too.

Learning isnāt just in your head. Itās physical.
In one study, mice grew new brain connections within an hour of practising a new skill. Practising again helped those connections last.
Every time you practise, the connections get stronger. Keep going, itāll be so so worth it.
