Distilled Medicine

On Melatonin and Jet Lag

Melatonin, the brain's own "darkness hormone," genuinely halves jet lag, but direction is everything. Because it accelerates your internal clock, take supplements on eastward journeys when you must sleep earlier than usual. Flying west? Skip the pills. Instead, shift your sleep schedule before travelling, then rely on brisk exercise and plentiful daylight at your destination to reset your body clock naturally.

On Strength Training

Cardio has its merits, but lifting weights is what preserves your independence. From your thirties onward, you shed muscle, especially explosive Type 2 fibres, leading to frailty and falls, a problem slimming drugs like Wegovy can worsen. To boost your metabolism, ward off disease, and stay steady into your eighties, strength train at least twice a week. Pick up some iron.

On Breathwork

Ancient yogis and modern scientists agree: controlling your breath genuinely calms the mind. Trials show five minutes of daily “cyclic sighing” (two quick inhales followed by one long, slow exhale) outperforms basic mindfulness for sustained stress relief, rivalling online therapy by boosting heart-rate variability and quieting anxious brain circuits. With zero side effects, make structured, slow breathing a daily habit to steady your nervous system.

On Microplastics

From car tyres to synthetic fleece, tiny plastics drift into our blood, brains, and arteries, acting as Trojan horses for disease. While scientists study precisely how these jagged nanoplastics damage our cells, playing safe is wise. Cut your daily intake: never microwave food in plastic, replace plastic kettles, choose natural fibres, and dust your home regularly to sweep away indoor debris.

On Ice Baths

Despite the bold claims of gurus like Wim Hof, freezing plunges won’t magically cure disease or transform your heart; rigorous trials show limited physical benefits, and fewer sick days may simply be placebo. However, icy soaks reliably flood your brain with dopamine and endorphins. Take a quick cold blast after your shower for a sharp mood boost, just don't expect medical miracles.

On Intermittent Fasting

Intermittent fasting works as well for weight loss as traditional calorie-counting, minus the obsessive maths. While near-starving lab animals triggers cellular repair that extends lifespan by 40%, human data on insulin and cholesterol remains murky. Use time-restricted eating as a simple tool to shed fat, but keep it moderate; extreme fasting risks stripping your muscle mass and weakening your immune system.

On School Smartphone Bans

While European school smartphone bans aim to curb teen anxiety, research proves classroom rules alone solve nothing if kids simply scroll at home. Heavy social media hits hardest during early puberty, specifically ages 11 to 13 for girls and 14 to 15 for boys, when brains change rapidly. Do not rely on school policies alone; actively supervise your child’s screen time at home during these vulnerable years.

On Super Shoes

Carbon-plated trainers with 40mm foam genuinely make you run 4–5% faster, giving you a 73% chance of a personal best. They absorb leg shock and save energy, but this speed is costly and fleeting: the springy foam degrades rapidly. If chasing a record, buy a pair. Log 20 to 50 kilometres before race day to prevent blisters and prime the bounce, then save them strictly for competitions.

On Posh Moisturisers

Skin needs hydration to stop dryness and cracks, especially as natural oils drop with age or frequent washing. Skip overpriced boutique tubs; modest chemist creams with glycerin, petroleum jelly, or ceramides perform identically. Spend extra only on retinol to smooth existing wrinkles, and ignore viral preventative fads. To genuinely guard against premature ageing before it starts, nothing beats a simple daily sunscreen.

On Butter

Butter is popular again, but its saturated fat raises cholesterol by blocking how your liver clears it. A 33-year study of 220,000 health workers linked a daily tablespoon to a 15% higher risk of early death. Though habits like smoking muddy the data, swapping ten grams daily for plant oils cuts cancer deaths by 17%. Skip margarine and switch to olive oil for a healthier heart.

On Fluoride

Despite headlines linking fluoridated tap water to lower IQs in children, evidence of harm remains thin. Fluoride is vital: it hardens enamel and neutralises acid-producing bacteria. While fortified water acts as a crucial safety net, daily brushing is by far your best defence. Do not rely on tap water, tea, or mouthwash alone; brush twice daily with fluoride toothpaste for maximum protection.

On Vaping

Despite widespread government bans and genuine risks like cellular damage from inhaled chemicals, electronic cigarettes are far less damaging than traditional tobacco. They strip out lethal tar and carbon monoxide entirely, offering a significantly safer alternative. If you currently smoke, switching to a vape roughly doubles your chances of quitting for good. If you do not smoke, leave them well alone.

On Red Meat

While steak provides easily absorbed iron and B vitamins, eating it daily damages your health. Massive studies show heavy beef-eaters rarely reach seventy in good shape, while daily sausages reliably drive up cancer rates. Trials also prove red meat spikes cholesterol and heart-clogging compounds worse than plant fats. Enjoy an occasional lean cut, but keep processed meats off the barbecue and pile your plate with vegetables.

On Daylight Saving Time

Shifting clocks forward for lighter evenings damages your body clock. Missing bright morning light while gaining evening sun scrambles the hormones governing sleep, stress, and appetite, triggering spikes in heart attacks, weight gain, and low moods, especially in teenagers. To protect your rhythm, step outside without sunglasses first thing every morning, switch to warm indoor bulbs after dark, and strictly avoid late-night screens.

On Electric Vehicles

While electric cars produce zero exhaust fumes, they are not entirely clean. Their heavy batteries cause extra tyre and road wear, shedding microscopic dust that slips into our bloodstream and damages lung tissue. Fortunately, regenerative braking helps them emit fewer total particles than petrol or diesel cars. To genuinely cut pollution, drive a smaller, lighter model rather than buying excessive battery range you rarely need.

On Habits

Building a new behaviour takes months of repetition until your brain’s automatic circuits take over from conscious willpower. To make a good habit stick, pair daily practice with small, immediate rewards that trigger a satisfying hit of dopamine. To break an unwanted habit, disrupt your surroundings by removing the familiar cues that spark the routine. Science explains the wiring, but sheer persistence remains your best tool.

On At-Home Brain Stimulators

Headsets from brands like Flow and Nurosym promise to ease depression, stress, and ADHD by passing tiny electric currents through your scalp. While hospital-grade brain stimulation is well-proven, the evidence for DIY consumer gadgets remains slim. Although recent trials and an NHS pilot show genuine promise, approach these pricey devices with caution. For now, rely on established medical guidance for mental health rather than unproven home technology.

On Hay Fever

Hay fever seasons are lengthening as warmer springs trigger pollen release as early as January, while urban pollution supercharges your symptoms. To protect yourself, start daily antihistamines or steroid nasal sprays before pollen counts spike. For severe sniffling, ask your doctor about sublingual desensitisation treatments, which reliably cut symptoms by a third without needing a blustery escape to the seaside.

On Juice Shots

While ginger and berry shots deliver a concentrated dose of antioxidants and anti-inflammatory compounds, juicing strips away the vital gut-friendly fibre and nutrient-rich skins found in whole fruit. Plus, active ingredients like turmeric require black pepper just to absorb properly. These miniature tonics won't harm your health, but they will dent your wallet. Save your money, skip the bottled hype, and eat whole fruit instead.

On Youth Contact Sports

Rugby and football carry real concussion risks. Standard padded helmets cannot stop a brain rattling inside a skull, and often simply encourage reckless play. To protect young athletes without blanket bans, support rules that limit training contact and group players by size rather than age. And remember: everyday hobbies like cycling, skateboarding, and horse-riding actually send far more kids to hospital with head injuries.

On Prostate Cancer Screening

Routine prostate-specific antigen (PSA) blood tests carry a 75% false-positive rate, easily triggered by exercise or sex. Because most prostate tumours grow slowly, surgery or radiation often risks permanent impotence and incontinence for a disease you would die with, not of. Discuss screening with your doctor at 50, or earlier if high-risk. If numbers spike, request an MRI scan and consider active surveillance over immediate, invasive treatment.

On Coffee

Your daily brew genuinely shields your health. Natural compounds in coffee fight inflammation, curb certain cancer risks, and slow neurological decline; drinking one to three cups daily even cuts ten-year mortality by 15%. Yet exceeding 400 milligrams of caffeine invites insomnia, tremors, and blood pressure spikes. Worst of all, stirring in cream or sugar erases those survival gains entirely. Keep your intake moderate, and drink it black.

On Protein

Unless you are pregnant, elderly, or lifting heavy weights, your standard diet already provides plenty of protein. The daily baseline is just 0.83 grams per kilogram of body weight. Even for serious gym training, muscle growth caps out at 1.6 grams per kilogram. Skip overpriced, additive-loaded powders and bars; choose whole foods instead to easily meet your targets while gaining vital bonus nutrients like calcium and iron.

On the Manopause

The “manopause” is largely a myth. Unlike women, men suffer no sudden hormone crash; testosterone simply dips by 1% a year, leaving men fertile into their eighties (just ask Al Pacino). Mid-life fatigue and flab usually stem from stress and desk jobs, not biological decline. Unless blood tests confirm genuine clinical deficiency, avoid testosterone therapy. While injections build muscle, they ironically risk triggering baldness and total infertility.

On Longevity Drugs

While near-starvation reliably extends animal life, most prefer a pill. Massive animal trials prove the transplant drug rapamycin mimics fasting to slow ageing, whereas the popular diabetes drug metformin fails entirely. Yet human trials for rapamycin remain disappointing, and nasty side effects like skin infections forced even obsessive tech biohackers to abandon it. Skip experimental chemistry. To live longer, eat sensibly, exercise, sleep well, and stub out the cigarettes.

On Bilingualism

While fluent speakers who switch languages daily might delay dementia by four years, a bit of university French will not magically upgrade your brain. The science on cognitive perks remains mixed, often skewed by wealth and schooling. Still, adult learning genuinely slows mental decline. Study a new language simply to talk to new people, and treat any added brain protection as a welcome side effect.

On Thimerosal

RFK Jr. wants to ban thimerosal, a flu jab preservative he blames for autism. Ignore the scaremongering. Massive British studies and Denmark’s own data prove no link exists. A single dose contains no more mercury than a tin of tuna. Do not let unfounded fears stop you from getting multi-dose vaccines. Banning this safe, cheap ingredient only harms poorer communities and validates dangerous anti-science myths.

On Creatine

Creatine is a safe, completely legal supplement that actually works. It quickly recharges your muscles, giving you a proven 10 to 20% power boost for heavy lifting or sprinting. But it is not just for sport. New studies show it sharpens memory, eases depression, and protects the brain from concussion damage. Take a daily scoop to upgrade your physical strength and keep your mind sharp.

On Probiotics

Gut microbes produce vitamins and fight IBS, obesity, and depression. Yet the booming probiotic market remains unregulated guesswork. If you buy pills, verify their backing via The Probiotic Guide app. Too many prebiotics just cause gas. Ideally, skip the pharmacy entirely. Feed your microbiome naturally with fibrous vegetables, legumes, and fermented foods like sauerkraut or yoghurt. Avoid unnecessary antibiotics. Real food always beats expensive, freeze-dried bacteria.

On Allergies

Allergies occur when your immune system panics over harmless crumbs or pollen. If you suffer from severe food reactions, do not assume you must simply avoid them forever. Ask your doctor about modern desensitisation therapies. Medicine now uses precisely dosed protein powders, targeted peptides, and antibody-blocking drugs like omalizumab to safely build your physical tolerance. Brilliantly, these methods now actually work for adults, not just children.

On Collagen

People pay £40 for collagen supplements (pulverised cow and fish bones) chasing smoother skin and stronger joints. Your body builds this protein naturally, though age, sun, and alcohol slow the process. Skip the overpriced powders. Rigorous trials show that a cheap whey protein shake repairs connective tissue far better than collagen does. If you still want those specific nutrients, standard supermarket gelatine does exactly the same job for pennies.

On Nightmares

Science shows bad dreams genuinely damage your health. If you suffer weekly nightmares, take them seriously. Studies reveal they predict early death better than smoking or obesity, prematurely ageing your chromosomes through stress hormones. They also signal looming illnesses like Parkinson’s or lupus. Do not ignore chronic bad dreams. Speak to your doctor about psychotherapy or medications like prazosin to stop them and protect your heart.

On Standing Desks

We were not built to sit all day, but standing desks are no miracle cure. Instead, their benefits depend on your age. For young adults, standing eases anxiety and lifts low moods. For older office workers, it will not fix your metabolism, but it reliably soothes lower-back pain. If your spine aches, alternate between sitting and standing. It is completely safe and offers genuine relief.

On Procrastination

Dawdling is an expensive vice, linked to thousands in lost earnings, severe pain, and depression. To stop putting things off, use mental contrasting: picture your goal, pinpoint the obstacle, and plan a workaround. Reinforce this with strength training to build mental resilience. Finally, eat breakfast, banish your smartphone from the bedroom, and prioritise sleep so you actually have the focus to get to work.
