10 Ways To Naturally Boost Dopamine

Dopamine is the “reward” hormone, and is responsible for motivation, as well as various oft-forgotten functions (such as spatial skills, motor functions, task processing, planning, and language). Sometimes, our relationship with dopamine isn’t what it could be, so here’s how to fix that:
Let’s get hormone-hacking…
Here are the 10 ways:
- The seesaw effect: reduce overstimulation by taking tolerance breaks from high-dopamine activities that aren’t particularly useful (like social media or phone games), allowing for natural enjoyment of daily activities that you’d normally find enjoyable. Think: if you died and negotiated to be sent back to life on the condition you’d appreciate it properly this time, what things would you then spend your time doing? It’s probably not Kingdom Crush Saga Farm 2, is it?
- Conscious state meditation: practise conscious state meditation, focusing inward to reduce anxiety and release dopamine. Even a few minutes a day can significantly enhance dopamine levels.
- Hack your REM cycles: optimize sleep, especially REM cycles, which produce the most dopamine. Aim to wake up after your final REM cycle to feel energized and happy.
- The runner’s high: engage in regular exercise, which boosts dopamine through physical exertion and can lead to feelings of relaxation and euphoria, often known as the “runner’s high.”
- Mood-enhancing music: listen to music that makes you feel good. Favorite songs can stimulate dopamine production, improving your mood and well-being.
- Bright light therapy: spend time in natural sunlight to stimulate dopamine production and elevate your mood, countering the negative effects of extended indoor time. If natural sunlight is not very available where you are (e.g. this writer who lives next to an ancient bog surrounded by fog and the days are getting short, at time of writing), then artificial daylight lamps are respectable supplement—but just that, a supplement, not a replacement. Despite how it looks/feels, natural sunlight (especially in the morning, to cue the circadian rhythm to do its thing) is beneficial even through cloud cover.
- Relieve stress for good: actively reduce stress, as it inhibits dopamine. Simplify daily routines and eliminate stressors to naturally boost dopamine and feel more relaxed. Of course, you cannot remove all stress from your life, so get good at managing the stress created by the stressors that do remain.
- Tap into your flow state: enter a “flow state” by focusing deeply on an engaging task, which can elevate dopamine levels and boost motivation and happiness.
- The hormesis effect: embrace mild physical challenges, like cold showers. The temporary discomfort will paradoxically increase dopamine (it’s the body’s way of saying “congratulations, you survived the hard thing, here’s a little treat, so that you’ll be motivated to survive the next hard thing, too”)
- Activate your inner artist: engage in creative activities that you find fun. The process of creating boosts dopamine and provides motivation, enhancing mood and enjoyment in life.

The Humor Habit – by Paul Osincup
10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.
Ask not for whom the bell tolls… It could be tolling for anyone. Don’t worry about it.It’s probably fine.
More seriously (heh), laughter is good for healthy lifespan, also called healthspan. It eases stress and anxiety, gives our brains neurochemicals they need to function well, and is very pro-social too, which in turn has knock-on positive effects for our own mental health as well as those around us.
This book is a guide to cultivating that humor, finding the funny side in difficult times, and bringing a light-hearted silliness to moments where it helps.
The title suggests it’s about habit-building (and it is!) but it’s also about knowing where to look in your daily life for humorous potential and how to find it, and how to bring that into being in the moment.
The style is that of an instruction manual with a healthy dose of pop-science; first and foremost this is a practical guide, not a several-hundred page exhortation on “find things funny!”, but rather a “hey, psst, here are many sneaky insider tricks for finding the funny“.
Bottom line: this book is not only a very enjoyable read, but also very much the gift that keeps on giving, so treat yourself!

More Mediterranean – by American’s Test Kitchen
10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.
Regular 10almonds readers will know that we talk about the Mediterranean diet often, and with good reason; it’s been for quite a while now the “Gold Standard” when it comes to scientific consensus on what constitutes a good diet for healthy longevity.
However, it’s easy to get stuck in a rut of cooking the same three meals and thinking “I must do something different, but not today, because I have these ingredients and don’t know what to cook” and then when one is grocery-shopping, it’s “I should have researched a new thing to cook, but since I haven’t, I’ll just get the ingredients for what I usually cook, since we need to eat”, and so the cycle continues.
This book will help break you out of that cycle! With (as the subtitle promises) hundreds of recipes, there’s no shortage of good ideas. The recipes are “plant-forward” rather than plant-based per se (i.e. there are some animal products in them), though for the vegetarians and vegans, it’s nothing that’s any challenge to substitute.
Bottom line: if you’re looking for “delicious and nutritious”, this book is sure to put a rainbow on your plate and a smile on your face.

Yes, blue light from your phone can harm your skin. A dermatologist explains
10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.
Social media is full of claims that everyday habits can harm your skin. It’s also full of recommendations or advertisements for products that can protect you.
Now social media has blue light from our devices in its sights.
So can scrolling on our phones really damage your skin? And will applying creams or lotions help?
Here’s what the evidence says and what we should really be focusing on.
Max kegfire/Shutterstock Remind me, what actually is blue light?
Blue light is part of the visible light spectrum. Sunlight is the strongest source. But our electronic devices – such as our phones, laptops and TVs – also emit it, albeit at levels 100-1,000 times lower.
Seeing as we spend so much time using these devices, there has been some concern about the impact of blue light on our health, including on our eyes and sleep.
Now, we’re learning more about the impact of blue light on our skin.
How does blue light affect the skin?
The evidence for blue light’s impact on skin is still emerging. But there are some interesting findings.
1. Blue light can increase pigmentation
Studies suggest exposure to blue light can stimulate production of melanin, the natural skin pigment that gives skin its colour.
So too much blue light can potentially worsen hyperpigmentation – overproduction of melanin leading to dark spots on the skin – especially in people with darker skin.

Some research suggests blue light might damage collagen, a protein essential for skin structure, potentially accelerating the formation of wrinkles.
A laboratory study suggests this can happen if you hold your device one centimetre from your skin for as little as an hour.
However, for most people, if you hold your device more than 10cm away from your skin, that would reduce your exposure 100-fold. So this is much less likely to be significant.
3. Blue light can disrupt your sleep, affecting your skin
If the skin around your eyes looks dull or puffy, it’s easy to blame this directly on blue light. But as we know blue light affects sleep, what you’re probably seeing are some of the visible signs of sleep deprivation.
We know blue light is particularly good at suppressing production of melatonin. This natural hormone normally signals to our bodies when it’s time for sleep and helps regulate our sleep-wake cycle.
By suppressing melatonin, blue light exposure before bed disrupts this natural process, making it harder to fall asleep and potentially reducing the quality of your sleep.
The stimulating nature of screen content further disrupts sleep. Social media feeds, news articles, video games, or even work emails can keep our brains active and alert, hindering the transition into a sleep state.
Long-term sleep problems can also worsen existing skin conditions, such as acne, eczema and rosacea.
Sleep deprivation can elevate cortisol levels, a stress hormone that breaks down collagen, the protein responsible for skin’s firmness. Lack of sleep can also weaken the skin’s natural barrier, making it more susceptible to environmental damage and dryness.
Can skincare protect me?
The beauty industry has capitalised on concerns about blue light and offers a range of protective products such as mists, serums and lip glosses.
From a practical perspective, probably only those with the more troublesome hyperpigmentation known as melasma need to be concerned about blue light from devices.
This condition requires the skin to be well protected from all visible light at all times. The only products that are totally effective are those that block all light, namely mineral-based suncreens or some cosmetics. If you can’t see the skin through them they are going to be effective.
But there is a lack of rigorous testing for non-opaque products outside laboratories. This makes it difficult to assess if they work and if it’s worth adding them to your skincare routine.
What can I do to minimise blue light then?
Here are some simple steps you can take to minimise your exposure to blue light, especially at night when it can disrupt your sleep:
- use the “night mode” setting on your device or use a blue-light filter app to reduce your exposure to blue light in the evening
- minimise screen time before bed and create a relaxing bedtime routine to avoid the types of sleep disturbances that can affect the health of your skin
- hold your phone or device away from your skin to minimise exposure to blue light
- use sunscreen. Mineral and physical sunscreens containing titanium dioxide and iron oxides offer broad protection, including from blue light.
In a nutshell
Blue light exposure has been linked with some skin concerns, particularly pigmentation for people with darker skin. However, research is ongoing.
While skincare to protect against blue light shows promise, more testing is needed to determine if it works.
For now, prioritise good sun protection with a broad-spectrum sunscreen, which not only protects against UV, but also light.

The Cold Truth About Respiratory Infections
10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.
The Pathogens That Came In From The Cold
Yesterday, we asked you about your climate-themed policy for avoiding respiratory infections, and got the above-depicted, below-described, set of answers:
- About 46% of respondents said “Temperature has no bearing on infection risk”
- About 31% of respondents said “It’s important to get plenty of cold, fresh air, as this kills/inactivates pathogens”
- About 22% of respondents said “It’s important to stay warm to avoid getting colds, flu, etc”
Some gave rationales, including…
For “stay warm”:
❝Childhood lessons❞
For “get cold, fresh air”:
❝I just feel that it’s healthy to get fresh air daily. Whether it kills germs, I don’t know❞
For “temperature has no bearing”:
❝If climate issue affected respiratory infections, would people in the tropics suffer more than those in colder climates? Pollutants may affect respiratory infections, but I doubt just temperature would do so.❞
So, what does the science say?
It’s important to stay warm to avoid getting colds, flu, etc: True or False?
False, simply. Cold weather does increase the infection risk, but for reasons that a hat and scarf won’t protect you from. More on this later, but for now, let’s lay to rest the idea that bodily chilling will promote infection by cold, flu, etc.
In a small-ish but statistically significant study (n=180), it was found that…
❝There was no evidence that chilling caused any acute change in symptom scores❞
Read more: Acute cooling of the feet and the onset of common cold symptoms
Note: they do mention in their conclusion that chilling the feet “causes the onset of cold symptoms in about 10% of subjects who are chilled”, but the data does not support that conclusion, and the only clear indicator is that people who are more prone to colds generally, were more prone to getting a cold after a cold water footbath.
In other words, people who were more prone to colds remained more prone to colds, just the same.
It’s important to get plenty of cold, fresh air, as this kills/inactivates pathogens: True or False?
Broadly False, though most pathogens do have an optimal operating temperature that (for obvious reasons) is around normal human body temperature.
However, given that they don’t generally have to survive outside of a host body for long to get passed on, the fact that the pathogens may be a little sluggish in the great outdoors will not change the fact that they will be delighted by the climate in your respiratory tract as soon as you get back into the warm.
With regard to the cold air not being a reliable killer/inactivator of pathogens, we call to the witness stand…
Polar Bear Dies From Bird Flu As H5N1 Spreads Across Globe
(it was found near Utqiagvik, one of the northernmost communities in Alaska)
Because pathogens like human body temperature, raising the body temperature is a way to kill/inactivate them: True or False?
True! Unfortunately, it’s also a way to kill us. Because we, too, cannot survive for long above our normal body temperature.
So, for example, bundling up warmly and cranking up the heating won’t necessarily help, because:
- if the temperature is comfortable for you, it’s comfortable for the pathogen
- if the temperature is dangerous to the pathogen, it’s dangerous to you too
This is why the fever response evolved, and/but why many people with fevers die anyway. It’s the body’s way of playing chicken with the pathogen, challenging “guess which of us can survive this for longer!”
Temperature has no bearing on infection risk: True or False?
True and/or False, circumstantially. This one’s a little complex, but let’s break it down to the essentials.
- Temperature has no direct effect, for the reasons we outlined above
- Temperature is often related to humidity, which does have an effect
- Temperature does tend to influence human behavior (more time spent in open spaces with good ventilation vs more time spent in closed quarters with poor ventilation and/or recycled air), which has an obvious effect on transmission rates
The first one we covered, and the third one is self-evident, so let’s look at the second one:
Temperature is often related to humidity, which does have an effect
When the environmental temperature is warmer, water droplets in the air will tend to be bigger, and thus drop to the ground much more quickly.
When the environmental temperature is colder, water droplets in the air will tend to be smaller, and thus stay in the air for longer (along with any pathogens those water droplets may be carrying).
Some papers on the impact of this:
- Cold temperature and low humidity are associated with increased occurrence of respiratory tract infections
- A Decrease in Temperature and Humidity Precedes Human Rhinovirus Infections in a Cold Climate
So whatever temperature you like to keep your environment, humidity is a protective factor against respiratory infections, and dry air is a risk factor.
So, for example:
- If the weather doesn’t suit having good ventilation, a humidifier is a good option
- Being in an airplane is one of the worst places to be for this, outside of a hospital
Don’t have a humidifier? Here’s an example product on Amazon, but by all means shop around.
A crock pot with hot water in and the lid off is also a very workable workaround too
Take care!

We urge you to overlook the cliché cover art (we don’t know what they were thinking, going for the headless suited torso) because…
This one could be the best investment you make in your career this year! You may be wondering what the titular 7 principles are. We won’t keep you guessing; they are:
- Professional development: personal excellence, productivity, and time management
- Leadership development: mindset and essential leadership skills
- Personal development: your motivation, character, and confidence as a leader
- Career management: plan your career, get promoted and paid well
- Social skills & networking: work and connect with the right people
- Business- & company-understanding: the big picture
- Commitment: make the decision and commit to becoming a great leader
A lot of leadership books repeat the same old fluff that we’ve all read many times before… padded with a lot of lengthy personal anecdotes and generally editorializing fluff. Not so here!
While yes, this book does also cover some foundational things first, it’d be remiss not to. It also covers a whole (much deeper) range of related skills, with down-to-earth, brass tacks advice on putting them into practice.
This is the kind of book you will want to set as a recurring reminder in your phone, to re-read once a year, or whatever schedule seems sensible to you.
There aren’t many books we’d put in that category!

Build Strong Feet: Exercises To Strengthen Your Foot & Ankle
10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.
A lot depends on the health of our feet, especially when it comes to their strength and stability. But they often get quite neglected, when it comes to maintenance. Here’s how to help your feet keep the rest of your body in good condition:
On a good footing
The foot-specific exercises recommended here include:
- Active toe flexion/extension: curl and extend your toes
- Active toe adduction/abduction: use a towel for feedback this time as you spread your toes
- “Short foot” exercise: create an arch by bringing the base of your big toe towards your heel
- Resisted big toe flexion: use resistance bands; flex your big toe while controlling the others.
- Standing big toe flexion (isometric): press your big toe against an inclined surface as forcefully as you can
- Foot bridge exercise: hold your position with the front part of your feet on an elevated surface, to strengthen the arch.
- Heel raises: which can be progressed from basic to more advanced variations, increasing difficulty
- Ankle movements: dorsiflexion, inversion, etc, to increase mobility
It’s important to also look after your general lower body strength and stability, including (for example) single-leg deadlifts, step-downs, and lunges
Balance and proprioceptive exercises are good too, such as a static or dynamic one-leg balances, progressing to doing them with your eyes closed and/or on unstable surfaces (be careful, of course, and progress to this only when confident).
For more on all of these, an explanation of the anatomy, some other exercises too, and visual demonstrations, enjoy:
