The ability of a person to reproduce naturally is referred to as fertility. When a man’s chances of getting his female spouse pregnant are poor, this is known as male infertility. Usually, it depends on how good his sperm cells are. Infertility can sometimes be related to sexual function, and it can also occasionally be related to the quality of the semen.

Male fertility really depends on a healthy sperm count. Sperm count can be affected by a variety of elements, such as nutrition and way of life. You can increase sperm count and overall fertility by incorporating particular nutrients into your diet. We’ll look at some fundamental dos and don’ts that have been demonstrated to have an impact on sperm count below.

Dietary do’s & don’ts to boost fertility in men:

Do’s

  1. Eat a balanced diet that includes plenty of fruits, vegetables, whole grains, lean proteins, and healthy fats.
  2. You certainly already know that vitamin C can strengthen the immune system. According to some research, consuming antioxidants like vitamin C may increase fertility.
  3. Cut back on processed and fast food, as they contain high levels of unhealthy fats, sugars, and artificial additives that can negatively impact fertility.
  4. Increase your intake of antioxidants such as vitamin E, and selenium, as they can help protect sperm from damage.
  5. Fertility in both men and women can benefit from vitamin D. Another vitamin that might raise testosterone levels is this one. Men who were vitamin D deficient had a higher likelihood of having low testosterone levels, according to one observational study.
  6. Fenugreek is an appreciated herb for both cooking and medicine. Supplements containing fenugreek have been demonstrated to considerably raise testosterone levels.
  7. One of the foundational elements of male fertility is getting adequate zinc. Additionally, taking zinc supplements may prevent the lower testosterone levels linked to overdoing it on high-intensity exercise.
  8. Ashwagandha is a herb used for medical purposes which can be added to your diet. According to studies, ashwagandha may increase testosterone levels, hence enhancing male fertility.

Don’ts

  1. Avoid or limit foods that are high in saturated and trans fats, such as red meat, fried foods, and baked goods, as they can decrease sperm count and motility.
  2. Reduce intake of soy products. Soy is abundant in isoflavones which causes an oestrogenic effect that drops the levels of testosterone.
  3. Avoiding consuming predator fish such as tuna and swordfish. These fish are high in mercury which can negatively affect our reproductive health and lead to fertility issues.
  4. Reduce your caffeine intake, as high levels can negatively impact sperm quality.
  5. Avoid or limit alcohol intake, as excessive consumption can decrease testosterone levels and impair sperm production.
  6. Avoid smoking and exposure to secondhand smoke, as they can damage sperm DNA and decrease sperm count.
  7. Don’t skip meals, as it can negatively affect hormone levels and overall sperm health.
  8. Foods in cans and tins are lined with a substance called bisphenol (BPA). Since bisphenol mimics oestrogen in the human body, it can have consequences akin to too much soy.

Follow these dietary dos and don’ts to improve your fertility and increase your chances of conceiving.

Biohacking aids in the alleviation or reduction of symptoms associated with mental health such as depression and anxiety.

Highlights

‧ The term biohacking gained a lot of popularity after former Twitter co-founder Jack Dorsey told his followers that he benefitted both mentally and physically from biohacking.

‧ Biohacking is typically safe as long as you don’t go too far and follow your doctor or specialist’s guidelines.

‧ Experts advocate that individuals who don’t understand, health, nutrition, neuroscience, and brain function should not try biohacking.

So you’re sick of being average? You desire more from your life and job. Netflix, wine, margaritas, reels, and nachos have all made you want to stay in bed. Sure, you’ve heard of productivity hacks, but what if one told you that the solution to your problem is ‘biohacking’, also known as ‘do-it-yourself’ biology.

The term biohacking gained a lot of popularity after former Twitter co-founder Jack Dorsey told his followers that he benefitted both mentally and physically from biohacking. Jack stated that biohacking enhanced his productivity, pointing out that he only eats one meal per day during the week and doesn’t eat at all on weekends. Some even claim that biohacking can help with almost anything – right from weight loss to cognitive function. However, the best biohacking results come from recognising what works for your body and avoiding what doesn’t. So to understand the real science behind biohacking, News9 spoke with some of the best experts in the world and here`s everything you need to know about it.

What is Biohacking?

Kolkata-based psychiatrist Dr Era Dutta explains, “Biohacking is the attempt at augmenting your performance, health and wellbeing through specific interventions. The term is meant to create the association of hacking – meaning creating a shortcut way through for your biology.”

“You can ‘biohack’ your mind, your body, your nutrition, exercise, sleep and more,” she continues. The beauty of biohacking is that it is DIY – do it yourself (with or without guidance). The process involves testing, monitoring and trying various combinations.

“Biohacking means different things to different people and is truly a very broad concept,” explains Vijeta Goyal, a Bangalore-based wellness consultant. “The notion is as follows: manipulating the biochemical processes in your body to bring about the best healthy version of yourself. The primary goal is self-improvement,” Vijeta adds.

Biohacking, according to Mumbai-based neurologist Dr Parthvi Ravat, is a technology-assisted strategy for modifying “homeostasis,” which refers to the body’s internal environment. “Simply put,” she says, “it is the use of science to support our bodies in boosting physical and mental performance, as well as battling various disorders.”

According to Shreya Gupta, a Chennai-based life coach, biohacking is something you instruct yourself to do. “It’s as if you tell yourself to exercise, so you get yourself a Fitbit or an Apple Watch to motivate yourself,” Shreya adds.

Biohacking is a science-based method of assisting our bodies in improving physical and mental performance as well as combating various ailments.

What are the most widely used bio-hacking tools?

In today’s world, we have access to commercially available tools and devices which are far more powerful than what even the most advanced clinics and researchers had only a few decades ago, remarks Supriya, a Delhi-based holistic health coach. Blood tests and health monitors give an extra edge in determining whether or not something is wrong with our bodies, Supriya explains.

“These days, I’m experimenting with taking ice-cold showers with water that’s 10 degrees celsius, and I’ve noticed a significant improvement in the condition of my skin and hair, and I’m tracking how it affects my natural hormone levels,” she further adds.

According to Dr Era Dutta, the most prevalent tools are:

Nutrition

Eliminating foods like gluten, and dairy; intermittent fasting.

Mental health

Cold baths, Wimhoff method, breathing pattern work, cryo chambers and meditation

Sleep

Melatonin supplements, white noise apps, weighted blankets, light therapy

Nootropics

A nootropic is claimed to be a class of substances that can boost brain performance. They can range from the more globally tried and accepted omega 3 fatty acids to Ginkgo Biloba to the more controversial use of ADHD stimulants, and micro-dosing of psychotropics.

Vitamins

Supplements of vitamins, infusions for better overall health. For example Vitamin B complex, micronutrients etc.

Adaptogens

Adaptogens are plants and mushrooms that help your body respond to stress, anxiety, fatigue, and overall well-being like Ayurvedic herb ashwagandha

Apps and technology

Wearable rings that monitor your body stats, EEG headsets that measure waves during meditation, sleep, mood changes etc.

More extreme

Nutrigenomics focuses on how the food you eat interacts with your genes and manipulates them.

According to Vijeta Goyal, biohacking comes in many forms. Some of them are as listed below:

Changes in lifestyle and diet

These include more conventional behaviours like yoga and meditation, eating consciously and healthily, spending time in nature, engaging in enjoyable exercise, and sleeping well, which you may not even realise are part of biohacking.

Technology

Don’t we appreciate our smartwatches, fitness trackers, and smart clothing? Have you ever considered your fitness tracker or weight-loss app to be biohacking? Biohacking is defined as the use of wearable technology to track your steps, remind you to drink water, or stand up and stretch – and it may be highly beneficial.

Grinders

Many people believe implanted technology to be the next step, although it has yet to become ubiquitous. Grinders, in general, aid in the optimisation of bodies by chemical injections, implants, and anything else that can be injected into the body to help humans grow smarter, quicker, and better.

Nutrigenomics

Nutrigenomics is the study of how food interacts with and influences your genes.

How safe are these tools?

Everything is safe when done in moderation and with care, as Dr Era Dutta demonstrated. “Isn’t it true that even in computer hacking, radical shortcuts don’t work? Similarly, staying away from extreme fads, conducting thorough research, knowing your own body and mind, and, most importantly, enlisting the assistance of a field expert when necessary are all essential components of biohacking properly.”

“Some kind of biohacking can be harmless,” Vijeta argues. “Sporting wearables, for example, or adopting lifestyle changes may be safe if done under the supervision of a scientific professional. Some biohacking techniques, such as grinder, are potentially harmful or illegal,” she adds.

What role does biohacking play in Human Performance Enhancement?

Biohacking, according to Vijeta, is supposed to assist you to achieve permanent, good change if utilised carefully and under professional guidance. “Physical, behavioural, or emotional improvements, such as lowering weight or reducing depressive symptoms, may reduce your chance of acquiring an illness to which you are genetically predisposed. Blood pressure and gut microbes are two examples of improved biological processes,” she explains.

“The whole idea of the human race is to be better, live longer, healthier and happier,” explains Dr Era adding that although biohacking hasn’t undergone concrete trials, it is meant to be the path.

However, according to statements made by its most trusted user, Jack Dorsey it can help with:

1 Alleviating or reducing symptoms of mental health issues like depressive symptoms, and anxiety features (this can be in conjunction with treatment)

2 Alleviating or reducing chronic health issues like diabetes, arthritis, chronic pain, chronic fatigue, blood pressure, migraine etc.

3 Obesity and weight loss

4 Helping in ace concentration, creativity and peak productivity

5 Reducing gut-related issues

Are biohacking promises such as longevity and slow ageing true or simply a fad?

Shreya says that the human brain is so powerful. “So, if you keep pushing yourself, you can accomplish your goals. I told myself in 2014 that I would establish a morning routine that included getting up, getting ready, and then just leaving my room. Since then, I haven’t missed it “she explains. “It all relies on your mindset and beliefs. So all you have to do now is educate your mind and force yourself to do it.”

How can biohacking be incorporated into daily life, and who should abstain from it?

With technologies like smartwatches, continuous glucose monitoring, health tracking devices, easy access to sophisticated testing, and so on, biohacking is simple for anyone to get into, remarks Supriya. She further continues: “Someone working, for example, may utilise biohacking to figure out when they have the greatest energy and when they have the least energy during the day. We can determine how much sleep we require to be the most creative and productive.”

Supriya further advocates that people who have high anxiety should not get into biohacking. “This is because if you’re tracking a biomarker and it’s out of range, you’ll look up the reasons online and find that there’s a potential you’re suffering from a deadly condition. This can frighten a lot of people, leading to them deteriorating their health as a result of their concern.”

Can biohacking be dangerous if you lack scientific training?

Supriya further points out that individuals who don’t understand, health, nutrition, neuroscience, and brain function should not try biohacking. “We are experimenting with our bodies and without the correct supervision or understanding, it may be harmful.”

Dr Parthvi believes that even silicon valley scientists and common biohackers are ignorant of the advantages and disadvantages. “It would be prudent to wait and see where this goes before attempting various biohacking tactics,” she advises.

Takeaway

Biohacking is typically safe as long as you don’t go too far and follow your doctor’s or specialist’s guidelines. However, be cautious in general. Experimenting on oneself without taking all of the necessary safeguards might lead to undesirable consequences.

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.
