Our Takeaways:

· Healthspan refers to the period of life where someone has good health.

· Healthspan is heavily influenced by diet.

· Supplements can also be used to increase healthspan.

Once upon a time, I had a pretty awkward and comical date in Santa Monica. I was new-ish to Los Angeles and decided to try out a dating site that was famous for its robust matching algorithms. However, on this particular evening on Pico Boulevard, their matching science was, well, not so robust.

I probably should have known something was awry when the handsome maitre d’ wished me “good luck” in a distinct, you’re-gonna-need-it kind of tone before taking me to the table where my date was already seated.

In lieu of a warm salutation, my date stood up, scanned me from toes to head (yes, in that particular order), and proclaimed with some audible disappointment, “You’re taller than your dating app profile said.” I replied, “It’s nice to meet you too” like any gracious Southern lady would, and proceeded to sit my tall self down. (I’m actually a not-so-tall 5-feet-6-inches, but as my dating profile clearly stated, “I like to wear heels,” so you know…do the math.)

The rest of that date could inspire a Saturday Night Live skit, but allow me to cut to the nutrition-relevant chase (since this article is about nutrition principles for a long and healthy life—I promise).

A nutrition Ph.D.’s long-range nutrition philosophy.

After asking my date the obligatory question about what he did for work, I kept the convo flowing by sharing that I was a dietitian and nutrition research scientist. As with lots of strangers, my occupation immediately inspired my date to share his personal foraging and dietary practices with no prompting at all.

Specifically, he shared that since he works best in the wee hours of the morning, he eats supper at around 2 a.m. Rotating between three particular fast food joints, he picks up the food earlier in the day and refrigerates it to enjoy later (you know, at 2 a.m.). To be clear, he does not work a night-shift job. He then went on to say with adamance that he did not like or consume fruits, vegetables, fish, or most “healthy stuff.” Why? His rationale: “Life is too short. I’ll worry about eating healthy later.”

While the daily video gaming and other hobbies he mentioned were never going to fit with my interests and use of time, his eating habits specifically were sounding alarm bells in my dietitian head. Given his nutrient-depleted diet, it took me everything not to convert our date into an emergency nutrition counseling session that at least covered vitamin C, omega-3s, and fiber for everyone’s sake. (OK, I’m 80% joking).

You see, our nutrition philosophies and game plans for the long term were categorically opposed. I threw a bright yellow mental penalty flag down on the dating field and called it quits (in my mind of course—after all, I needed to finish my salmon and vegetables first!).

And while a date might just be a date, its future potential certainly plays a role in deciding whether to prolong said dating journey. The longevity of our hypothetical relationship was doomed for a variety of dating site algorithm failures, but like any research-minded Ph.D. nutritionist might ruminate (OK, maybe just me): This man’s lack of actual longevity potential flashed before my eyes as his shocking nutrient-lacking lifestyle was revealed.

It was like he had zero dollars in his nutrition 401(k) account, and I’m sorry, but that just doesn’t add up to a lengthy partnership.

Healthspan is not fixed (it’s malleable!).

Whether you’re looking for a good nutrition life match or simply cooking dinner for yourself, do we actually know what constitutes longevity food? And do we have the luxury to worry about eating healthy later, as my date suggested? The science is quite clear on that: Nope. At least not if the goal of living on this earth is thriving (instead of just surviving).

Regardless of your life stage, now is always the time to prioritize nutrition and other healthy lifestyle practices (i.e., restful sleep, physical activity, healthy body composition, smoking cessation, moderate or scant alcohol consumption, etc.). But is starting earlier best? Absolutely.

And as it turns out, we even know that certain patterns of macronutrients, micronutrients, and phytonutrients (i.e., plant bioactives) and their timing of consumption are tied to longer healthspan.

It’s so important to note that healthspan is malleable! Like the ultimate alley-oop basketball move: Your genes might be the setup, but nutrition is definitely the follow-through. Suboptimal nutrition can be a weak-sauce layup that barely makes it into the net, while a nutrient-dense lifestyle is like a fabulously confident dunk with some impressive hang time.

Smart nutrition: the ultimate power play for longevity.

Beyond the obvious role of taking in enough nutrients every day (i.e., get serious about nutritional sufficiency, whether that means a truly comprehensive multi, effective vitamin D3 supplement, filling your omega-3 gap, or more), our body is nutrient-responsive.

That’s because nutrients are fabulously multifunctional. Aside from being delicious, nutrition has the ability to positively affect so many physiological pathways and outcomes. Here are just a few that come to mind:

‧ boots-on-the-ground antioxidant fighting power against oxidative stress via an array of antioxidant vitamins, minerals, and phytonutrients from plants (fruits, vegetables, herbs, and more)

‧ anti-inflammatory marine omega-3s for resolution of inflammatory pathways

‧ prebiotic fibers and probiotic microbes for robust gut health

‧ 24/7 cellular cleanup and rejuvenation activities like detoxification and autophagy (think glutathione, milk thistle, CoQ10, etc.)

‧ adaptogens and nootropics for mental resilience and cognitive performance

‧ normocaloric intake of plant-centric carbs, proteins, and fats within a defined intermittent fasting window (e.g., 12 hours each day) for healthy body composition and cardiometabolic health

‧ intricate interplay of food and nutritional bioactives with your genes and DNA via precision nutrition solutions (e.g., for MTHFR gene variants) and epigenetic mechanisms

Smart nutrition is like a strategic biohacking strategy you tap into daily to thrive for the long haul. A recent, comprehensive research review examined this fascinating area of longevity nutrition, so you’ll want to check out the highlights and key nutritional pillars that represent a literal investment in your future.

Longevity nutrition is core to mbg philosophy, too.

Of course, if you’ve read mindbodygreen content for any period of time, you’ll probably know the pragmatic power of nutrition for health and longevity. This is not just something we cover in a journalistic sense. Longevity nutrition is actually core to the mindbodygreen philosophy, our portfolio of products, and the way we live.

In fact, the suite of premium products in mbg’s longevity & vitality collection were created with your healthspan in mind. By taking longevity support to the next level, these bioavailable nutrients, botanicals, and bioactives transform your daily regimen for healthy aging.*

From the 30 trillion cells that make up the human body, to how we look and feel—the fact is the amounts, types, and timing of nutrients and phytonutrients we choose to consume are absolutely pivotal to our health today and tomorrow. Nutrition isn’t sitting on the sidelines. It’s a versatile quarterback calling the plays.

Whether that “play” is to keep your brain sharp as a tack, maintain strong muscles and bones, promote insulin sensitivity and blood glucose balance, elevate gut microbial abundance and diversity, bolster your resilience to stressors, ensure your immune defenses are game for inevitable challenges that will come, or nurture collagen production—ultimately, these are all longevity plays, individually and collectively. They all rely on smart nutrition rooted in science.

The takeaway.

Some matches simply aren’t meant to be. But thankfully, unlike dating sites and the unpredictable nature of some human relationships, the “algorithm” underlying longevity is less cryptic, and healthful nutrition is paramount.

 

How the rich and famous are biohacking their homes

A pool and gym just don’t cut it any more. How about your very own cryotherapy chamber or red-light therapy bed? Helen Kirwan-Taylor investigates the new ‘biohacking’ home technology promising to supercharge your health

Our Takeaways:

· The use of infra-red light treatment and hyperbaric oxygen therapy are considered stables of biohacking.

· While not absolutely necessary, some biohacking tools and practices can be very expensive.

· While expensive treatments are available, they do not replace foundational aspects of nutrition and natural living.

If you don’t sleep in a hyperbaric oxygen pod, like Justin Bieber, or at the very least on an infrared mattress, then what’s wrong with you? Do you have self-esteem issues? These days, you need to get with the biohacking programme. Just look around wealthy London: the diggers are in, basements are being excavated, and oxygen chambers and flotation tanks are being speedily installed. Behold the new temples to the pursuit of youth.

Biohacking, if you didn’t know, is the practice of interfering with your own biology in an attempt to improve it. Staples include infra-red light treatment and hyperbaric oxygen therapy (HBOT), which delivers pure, pressurised oxygen to the body. Amazing claims are made for both. But what’s really astounding is the size of this elite, luxury market: the consultancy firm McKinsey predicts that over the next decade biohacking could become a trillion-dollar industry.

Already almost every aspect of it has been nano-hacked. For example, there’s no longer any need to fast now that you can have ProLon meals (which trick the body into autophagy, or cell-cleansing) delivered to your door. Or you could just pop two longevity spermidine supplement pills (a favourite of the Vivamayr clinic) and achieve the same effect. Similarly, if ice baths sound like too much hard work, you can always clamber into your own thermal shock chamber (try it out first at Ice Health Cryotherapy in Kensington – unlike most cryotherapy chambers, it doesn’t require full immersion and can therefore be used while you listen to music). And rather than follow a restrictive keto diet to burn fat and increase mental clarity, you can simply knock back some deltaG – at £59.99 for a 59ml mouthful, the most expensive keto drink on earth. Created by Oxford professor Kieran Clarke and available to buy from Wellgevity, it’s like drinking a high-octane body fuel and a sip or two will allow you to glide through the most difficult presentation.

But no doubt your wellness consultant will tell you that. Enter Julie Cichocki. The founder of the ‘wellness curator’ Kloodos, Cichocki is a one-woman hacking machine who can provide you with what is currently only available to celebrities or athletes. I happen to ring her as she is on her way to Southampton to create a complete biohack unit in the house of a self- made tycoon and, for a taster, she sends me to Repose on High Street Kensington to try out the number- one contraption on the market: the £60,000 Mitogen photobiomodulation (red-light therapy) bed. Its light goes so deep, says Cichocki, that it triggers the production of the magical, all-singing, all-dancing source of youth – a cell-energising molecule called adenosine triphosphate (ATP).

For ultimate relaxation, Cichocki continues, ‘the bed allows you to surrender and move into critical beta mode’ – and it is often the first piece of kit she will put into the houses of her high-net-worth clients. Most likely, this will be followed by a whole-body cryo-chamber (£125,000), a hyperbaric oxygen chamber (£75,000), a dry float tank (£27,000) and an infra- red sauna (£6,000), plus an ice bath and plunge pool.

‘It’s not unusual for clients to spend upwards of £150,000,’ says Cichocki. And why not? Biohacking promises great things, from cell renewal to disease prevention; it’s no wonder every Hollywood star, Silicon Valley magnate and premier athlete is kit-ting out their home gyms with the latest that technology can provide.

The ‘gateway’ hack is infrared light – supplied in panel form by Bryan Gohl of Red Light Rising, whose ‘Armoury’ model costs around £12,000 and is about the same size as a door. (The actor Tom Hopper swears by it and has bought two for his personal use, in ‘The Advantage XL’ size.) Its applications go way beyond enhancing performance and energy. ‘Some people claim it helps their eye- sight,’ says Gohl. ‘Others, that it eases their menopause symptoms. And we know it really helps with muscle pain and joint stiffness.’ Other pluses? It acts like a giant seasonal affective disorder (SAD) corrective light; it doesn’t stop you from being able to scroll through Instagram while you use it, as the infrared beds do; and many, myself included, have found it useful in combatting long-Covid symptoms.

Then there’s hyperbaric oxygen therapy, a fashionable hack at the moment because, apart from helping to speed up recovery from operations or illnesses, it can also help brush away the mental cobwebs. City types in particular are addicted to its ‘natural high’ nd can be found in droves at The Wellness Lab in Knightsbridge after the markets close. (A bonus of the spaceship-like chambers is that they double as divans.) And don’t forget intravenous infusions such as nicotinamide adenine dinucleotide (NAD+) – the ultimate anti-ageing chemical, endorsed by celebrities including the actress Davinia Taylor – which is available at Hum2n in Chelsea.

Our Takeaways:

· Exposure to sunlight for 10-15 minutes straight is useful for the body’s production of Vitamin D.

· Sleep is not only important for recovery but also for development and improvement

· “Earthing” can be used to positively charge the body

LIGHT: The conductor for our cells

What’s in it for me?

Our cells, our organs and our whole body can only work in harmony; the liver, lungs, kidneys, heart, brain, skin and muscles do have to know what each other are to make the whole system work. It all needs to be finely tuned, and the body uses hormones and messenger substances for that purpose. But the most important thing is light, which we absorb via the eyes and skin. Light is the most important conductor in our lives; the right light at the right time transforms this chaotic mass of 100 trillion cells within our body into a perfectly tuned orchestra. UV-B light is also the ingredient that our body turns into the vital vitamin D.

What should i do?

Go outside. Absorb natural light morning, noon and night, and do so with as much exposed skin as possible for 10 to 15 minutes in the afternoon. (Tip: your skin forms vitamin D when the sun is higher in the sky than 42°, so if the shadow you cast is shorter than you, all is good for vitamin D formation.) Avoid the blue light of your computer screens and/or use blue-light-blocking glasses. And while we’re on cell interplay, I’ve stopped wearing sunglasses for one reason: wearing them increases the risk of sunburn. The body is receiving two contradictory signals—shade on the eyes yet light on the skin – and just cannot deal with them properly.

Who knows more?

Dr Alexander Wunsch does. He’s the world’s most important photobiologist and there are multiple fascinating podcast episodes about him. Also, be sure to look up his channel on Vimeo. He’s also written a book about photobiology in his native German language: Die Kraft des Lichts [The Power of Light].

SLEEP: The number 1 Biohack

What’s in it for me?

It couldn’t be simpler and we can’t say it often enough: sleep better and you’ll live better. Sleep is the best, most important and most effective agent for relaxation, rest, regeneration and recovery there is. It’s the foundation upon which our performance, health and longevity are built. Sleep makes us wiser because it’s when we sort out the stuff we’ve learned that day. We get stronger and more resilient because we don’t just repair the damage that training has done but we also improve our starting condition; this is what we call the training effect. We get healthier because the lymphatic system cleanses our brain of all the waste products. Cell damage anywhere in the body is repaired, too.

The oft-used comparison of sleep to recharging your mobile battery is incorrect because we humans recharge our own battery, and more than that, we even improve our batteries’ charging capacity. And all we have to do is make sleep our top priority.

“In sleep we get smarter, we get stronger and more persistent, we get healthier. Let us make sleep the number one priority in our lives.”

Andreas Breitfeld pays attention to many small factors to maximize on sleep.

What should i do?

You can actively improve your sleep by not eating anything for the last three hours before you go to bed, switching off stimulating light impulses for the last two hours (as little screen light as possible and wear blue-light-blocking glasses) and avoiding stress in the evenings wherever possible. Your bedroom should be very dark and cool, preferably between 16°C and 20°C. Magnesium works for many people, though not all, as does ashwagandha, but give both a try. Two to three hours before going to bed, I take melatonin, the so-called sleep hormone, which can do so much more than just make us tired. Some doctors advise against it, but current studies claim that your body’s own production of it isn’t affected by you taking it. Melatonin really is worth a try.

Austria’s Professor Günther Amann-Jennson has devised the Samina sleep system; it’s expensive but probably the best thing currently on the market. Amann-Jennson, a doctor and psychologist, makes lots of excellent content [in his native German] available for free on his website at einfach-gesund-schlafen.com.

EARTHING: The positive in the negative

What’s in it for me?

This may all sound like esoteric magic, but it is crystal-clear physics. Ion exchange with the negatively charged Earth reduces oxidative stress and the horribly dangerous chronic inflammation processes that come with it because it positively charges our body. (Oxidative stress is, incidentally, a turbo boost for the ageing process.) All we have to do is come into direct contact with the planet and let the electrons flow by walking barefoot in a meadow or going swimming in a natural body of water, for example. Another benefit of coming into direct contact with the Earth: the 7.83 Hertz at which the Earth vibrates is what we call the Schumann resonance and it might even reduce electromagnetic stress.

What should I do?

Take your shoes off and walk barefoot in a garden, in the woods or through a meadow. Leap into a natural body of water every now and again instead of just splashing around in the ice-bath. You can also earth when you sleep, but that’s another topic because it only makes sense to use earthing sheets or other similar items when there’s no electric smog caused by Wi-Fi and the like. Otherwise earthing will turn you into a human antenna – pretty much the exact opposite of what we’re trying to achieve here.

Who knows more?

Austria’s Marco Grosch, the self-titled minimalist bio¬hacker, has excellent knowledge of a broad range of topics in this field. One of those topics is earthing, to which he devotes his German-language website (minimalist-biohacker.com) and his Instagram feed.

BREATHING: Our brain’s remote control

What’s in it for me?

Breathing is an incredibly powerful tool; I can breathe myself into a calm state or breathe myself into a rage and frenzy. No other action has such direct access to my brain and autonomic nervous system. Try box breathing, for example – breathe in for four seconds, hold your breath for another four, breathe out for four, hold your breath for four seconds again. It helps calm the nerves. Wim Hof’s method of breathing can strengthen the immune system and, when combined with the cold, it can even relieve depression. But just by consistently breathing through your nose, not your mouth, every day, you’ve already taken a big step towards improved health.

“The mouth is there for eating, for kissing and—I know that particularly well—for talking. But not for breathing. Especially not to breathe in!”

Breitfeld says to breathe through your nose in everyday life should be the goal

What should i do?

Breath through your nose. I’ve focused a lot on this subject recently, including mouth-taping: by taping my mouth up when I go to bed, I force myself to breathe through my nose, which takes a lot of getting used to but improves my sleep. The mouth is for eating, kissing and – I know this very well – talking, but not for breathing and definitely not for breathing in. The advantages of breathing through the nose are huge. It removes particles from the air we breathe, it moistens and warms or cools it and it means the body gets more nitric oxide, which broadens the blood vessels. Nitric oxide also decreases blood pressure, and some will know that it even helps medication like Viagra achieve success. I recommend that everyone experiments with their breathing. There’s so much to discover, so familiarise yourselves with the ideas of Wim Hof and the still relatively unknown Konstantin Buteyko. It’s really fun and can change your life.

Who knows more?

Kasper van der Meulen is my breathing guru. He offers really amazing breathing training in the Netherlands. He’s an extremely nice guy who is good at what he does. Find out more at kaspersfocus.com or find him at @kaspersfocus on Instagram.

FASTING: Cleanse, don’t eat

What’s in it for me?

Fasting is when the body gets no source of energy from solids or liquids. (Light is also really a form of energy but doesn’t count here.) After a while, the body begins to take the energy it needs from its reserves – and it has plenty of them. Glycogen in the muscles and liver gets depleted first and then, of course, there’s all that body fat, which even thin people have. But it’s all much smarter than the body just using up stored energy. While fasting, the body begins to break down its own cells and uses them to produce energy. The fascinating part is it burns only damaged cells – not fully operational ones. This process, known as autophagy, turns out to be the most efficient form of inner cleansing.

What should i do?

I eat O.M.A.D.—one meal a day—usually a very early dinner. Strictly speaking, I’m not fasting at all because I have coffee with butter and MCT [medium-chain triglyceride] oil in the morning and before noon. Fasting covers a fairly broad spectrum. For some it’s enough to avoid carbohydrates and protein, while others are more radical and think that even drinking tea or coffee or taking vitamins or magnesium would break the fast. But however you define it, start by skipping breakfast a couple of days a week (water, black coffee and unsweetened tea are fine). In step two, don’t eat the first meal of the day until at least 16 hours have passed since the last meal the day before.

Who knows more?

Julia Tulipan, of Vienna, Austria, is one of the top experts in ketogenic nutrition. The keto diet is sort of preliminary fasting, and Julia and her husband have brought their own Tulipans range of keto convenience foods to some supermarket shelves. Her website, juliatulipan.com, and Instagram feed, @paleolc, provide a lot of free German-language content and her Evolution Radio Show podcast [also in German] is fascinating listen.

FOREST: Green bathing

What’s in it for me?

The term ‘forest bathing’ has really taken off of late. It sounds spectacular, perhaps, but all it means in reality is going into the woods on a regular basis for a very slow and deliberate walk. What can that give a biohacker? Much more than you might think. The forest air contains thousands of terpenes, aromatic plant-based substances that fire our immune system and could even lower the risk of some cancers. The green of the forest and the natural calm reduce stress hormones—and not just during your forest bath because the reduction is still detectable for several days afterwards. Thorough research into forest bathing has been carried out in Japan and South Korea, where it’s applied as a recognised form of medicine. So in future, perhaps GPs will be telling their patients to take a hike, and I think that’s wonderful.

“In Japan and South Korea, doctors send their patients out for walks in the forest. ‘Shinrin-Yoku’, forest bathing, is a highly effective therapy.”

Aromas in the forest are even said to reduce the risk of cancer.

What should i do?

Walk through the forest for an hour or two a week, preferably alone and, importantly, without your mobile or any other electronic devices. It does everyone good. Ideally take a few steps barefoot or, if nobody is looking, hug a tree every now and again for the earthing and ion exchange, as mentioned above. But if you want to make your trip to the forest even better, the greatest concentration of terpenes occurs during misty or rainy weather. We humans have a need for nature. And once you learn—or relearn—to tune into it, you understand that your body has a sort of level indicator to show whether we have absorbed enough nature or not.

Who knows more?

Rolf Duda, aka Peakwolf, from Switzerland, is a former management consultant and a hero among biohackers. He has a soft spot for nature and the forest, but whatever he talks about, it’s always well-founded, intelligent and entertaining. I’m a true fan. His German-language website (peakwolf.ch) is a good introduction to Rolf’s world—from there you can go to his blog, podcast and Instagram feed.

WATER: 99/100

What’s in it for me?

Only every 100th molecule in our body isn’t a water molecule. Yes, you read that right. 99 out of 100 molecules in our body consist of two hydrogen and one oxygen atom. We humans are a (cleverly structured, admittedly) watery solution. So water is a prerequisite for everything working —every metabolic process, every detox, every nerve impulse, every thought, every emotion. Just a couple percent too little water in the body—I’m speaking one or two litres here—and our capacities are radically decreased.

What should i do?

Drink water. Personally, I drink filtered and revitalised water but in most countries you can mostly drink the tap water without a second thought. How much should you drink? Anything under 0.3 of a litre per 10 kilos of bodyweight is actively harmful to your performance and health. If you weigh 70 kilos, 2.1 litres a day is enough if you don’t work out, have almost no stress and don’t go to the sauna. But 0.3 litres per 10 kilos of bodyweight is the minimum. Make sure that you really drink enough for a full week. (Mostly in the morning so that your urine is very clear by noon.)

Who knows more?

Thomas Hartwig. His Berlin start-up Leogant creates perfect water filtration and treatment systems. Thomas is a water philosopher. The best sources of knowledge are the podcasts he has appeared on, such as the Flowgrade Show, with my friend Max Gotzler.

MEDITATION : The brain improver

What’s in it for me?

There’s not much more to add to what thousands upon thousands of studies confirm; meditation makes us smarter, happier and more creative. It’s probably the best and simplest thing we can do for our brain health. Meditation is something like the continuation of breathing and sleep’s little brother. There’s no right or wrong in meditating, and the only mistake you can make is not meditating regularly.

What should i do?

During my summer holiday last year, I did a sort of huge mindset reset where for two weeks solid I meditated my back side off for literally four, five, six hours a day. In my daily life, I now very consciously take a couple of minutes out, where I close my eyes, breathe in calmly and breathe out more calmly still, focusing solely on my breath. I really like playing around with the Muse headband that supervises how deep my meditation goes. There are some incredible meditations apps out there – and the best one that’s free of charge is Oak.

“If you want to take advantage of digital support: The best free meditation app is ‘Oak’, the best German-speaking one is ‘7Mind’.”

Apps and gadgets can be helpful meditation tools, according to Breitfeld.

Who knows more?

Germany’s Manuel Ronnefeldt, who founded the 7Mind meditation app – take a look at 7mind.de/en, where you’ll find a lot of free and detailed information.

HEAT: The life-lengthener

What’s in it for me?

Heat for free? Yes, by sitting in a thermal spring or going out in the blazing sun in the summer. Where I really like to go is the sauna. All types of sauna work, even though the effects differ depending on whether you’re using infrared or heated rocks – but the principle is the same. The main benefit is that sweating cleanses our bodies via its largest detoxifying organ, the skin. The second and third most important benefits (and there are a whole lot more besides) are an improved cardiovascular system and the so-called heat shock proteins the body forms. The sauna is, to put it simply, a boot camp workout for our cells. There are mind-blowing studies from Finland about how effective regular sauna visits are. The result is up to 40% lower mortality rates. In other words, during the reference period – the study ran for more than 20 years – regular sauna-¬goers reduced their risk of death by almost half.

What should i do?

My lab has an infrared sauna that I use several times a week. Sometimes I treat myself to a hot bath one to two hours before going to bed as perfect preparation for a good sleep. But, beware, heat and digestion do not make good bedfellows. Don’t go to the sauna for two, or even three, hours after eating. Heat means stress for the body, and you don’t digest well when stressed.

Who knows more?

Johannes Kettelhodt, the mastermind behind the Clearlight infrared cabin. He and his team have achieved something special. They make their saunas without creating any electric smog. That is a significant help as the body detoxes.

COLD: Inflammation’s natural enemy

What’s in it for me?

Inflammation can be a good thing because it triggers an alarm signal in the body at the start of a healing process. An injury doesn’t heal despite the inflammation; it heals because of the inflammation that forms around it. But inflammation can do serious long-term damage if it goes on too long. Low-threshold inflammation is definitely not something you want to have in your body, and the cold helps reduce it, while accelerating regeneration after sport and injury and improving the immune system. it stimulates the vagus nerve and with it our heart rate variability and ability to relax.

What should i do?

I take a five-minute ice-bath where the water is about 3°C almost every day in a repurposed deep-freeze in my lab. But how to get started? The easiest tip for beginners is to alternate your showers. At the end of your morning shower, just let the water run cold for 30 seconds and then do another 30 seconds in warm water. The hot-cold alternation is also very effective for recovery after sport. A little tip for amateur bodybuilders: taking a cold shower for longer than ten minutes (in 10°C water) or an ice-bath for longer than three minutes (in 3°C water) after training will make you recover more quickly, but it will also slow down muscle growth quite a lot, so take a shorter cold shower or only do the next cold therapy the following morning.
