The passing of Dr. Michael Mosley in June 2024, attributed to heatstroke during one of Greece's hottest days, left an extraordinary outpouring of grief and shared stories from countless individuals who had benefited from his health advice. To his family, the extensive archive of his material, from the "Just One Thing" podcast to his numerous TV programmes, felt like a blessing. Yet, it took months for his loved ones, including his son Jack, to feel able to engage with his produced content again. Eight months after his death, relistening to "Just One Thing" proved to be an emotional but profoundly impactful experience, revealing a treasure trove of useful, evidence-based, and easy-to-action information for making small, yet cumulatively significant, changes towards a happier, healthier, and more productive life.

Michael Mosley's authenticity was a cornerstone of his broad appeal. He openly admitted his personal struggles with health, including a sweet tooth, a probable chocolate addiction, insomnia, and a dislike for exercise. This personal understanding enabled him to genuinely empathize with others facing similar challenges, driving him to devise methods for incorporating vital changes that were not burdensome and could easily become habits. A journalist, producer, presenter, and writer, Mosley was instrumental in popularizing lifestyle medicine, an area he found deeply fascinating through his interactions with renowned scientists. He was always eager to share new research, even enthusiastically discussing Nordic walking in his final conversation with his son. His passion for these topics shone through, leaving a lasting impression, evidenced by the popular adoption of his "brushing teeth on one leg" tip. His legacy endures, and his tips continue to be shared through "Just One Thing Volume 2," ensuring that individuals can persistently enhance their lives through his unique insights.

Among the myriad of "Just One Thing" tips, several focus on enhancing daily well-being: Tune into Pain Relief by listening to music. Research indicates that the endorphins released by music bind to opioid receptors in the brain, reducing pain perception and inducing mild euphoria. Clinical trials have shown that surgical patients listening to music required 18 percent less morphine on average. Mindful listening, focusing on sounds, rhythms, and emotions, can also stimulate brain regions linked to memory, movement, reward, and emotion, bolstering cognitive function. Creating a playlist of favorite music and listening without distractions for ten minutes daily is recommended.

Another crucial tip is to Restrict Phone Use. Even minimal reduction in mobile phone use can yield significant health benefits, including improved general health, enhanced immune function, and reduced levels of loneliness and depression, as demonstrated by a Swansea University study on social media use. Limiting phone time also benefits posture, counteracting "text neck" – the neck and shoulder pain caused by prolonged chin-to-chest posture while looking at a phone. Tilting the head forward, even at a 45-degree angle, can increase the load on the spine to 22kg, according to a 2014 study.

Embracing the Rain offers unexpected health advantages. Despite the UK's average of 159 rainy days a year, rain helps purify the atmosphere, removing pollutants and improving air quality. A Japanese study found rainfall reduced harmful fine particles in the air by about 20 percent. Walking in or after rain provides cleaner air beneficial for the lungs. The rich scent of wet earth, petrichor, primarily from geosmin produced by soil bacteria, also has positive effects. A Korean study showed that exposure to geosmin elevated serotonin levels, shifted brainwave activity to a more relaxed state, and reduced C-reactive protein, a marker of inflammation, suggesting calming and anti-inflammatory effects.

For physical health, Start Lifting Weights. This activity improves mood, immunity, heart, brain, and bone health, and can slow aging. Practical exercises include bicep curls (using a milk bottle if weights aren't available, aiming for three sets of ten repetitions per arm) and weighted squats (using a backpack filled with books, performing three sets of ten repetitions). Proper form and gradual progression are emphasized.

Pick up a Pen for expressive writing. In a digital age, writing thoughts and emotions by hand may seem antiquated, but science supports its profound health benefits. Setting aside 15 minutes to write continuously about deep thoughts and emotions, without concern for grammar or structure, can improve sleep, enhance mental clarity, and even accelerate healing. This free, low-effort, and private practice is backed by decades of psychological and medical research.

Read a Poem Aloud to foster calm. While quiet reading of poetry can ease stress, speaking it aloud adds another dimension. Swiss Association of Art Therapies research found that reading rhythmic poetry regulates breathing, slows heart rate, and increases heart rate variability (HRV), a measure of stress response. This effect was more pronounced than deliberate deep-breathing exercises. The key lies in rhythm, which naturally slows and lengthens breath, stimulating the parasympathetic nervous system. Poems with regular patterns of stressed and unstressed syllables and longer lines, like "To Autumn" by John Keats or "'Hope' Is The Thing With Feathers" by Emily Dickinson, are recommended for five to ten minutes, three or four times a week.

Walk Backwards for a low-impact activity that boosts stability, balance, eases lower back pain, and enhances memory and brain power. This practice engages underworked muscles like calves, shins, and quadriceps. A Texan study showed blood lactate levels were three times higher during backwards walking than ordinary walking, yet it's gentler on knees and back. Professor Janet Dufek advises engaging core muscles, pulling back shoulders, and lifting the chest for safe execution.

Get an Early Night to improve mood. Studies indicate that earlier bedtimes correlate with fewer negative thoughts. Research from Harvard, MIT, and the University of Colorado found a strong link between sleep midpoint and depression risk. Shifting bedtime an hour earlier could theoretically reduce depression risk by 23 percent, and two hours earlier by 40 percent. This is partly due to increased morning light exposure, which releases feel-good hormones and resets the circadian clock, crucial for mental and physical health. Disrupting this rhythm can increase metabolic problems, mood disorders, and weaken immunity.

Dig for Microbiome through gardening. The physical exertion of gardening is beneficial, but exposure to soil bacteria also boosts the gut microbiome – the community of micro-organisms vital for digestion and immune function. Dr. Hannah Holscher's research at the University of Illinois Urbana-Champaign showed gardening families had greater diversity of gut microbes and consumed more dietary fiber, specifically more bacteria capable of breaking down fiber within the intestinal tract.

Wade in Water to benefit from swimming's unique advantages. Gentle on joints and accessible to all ages, swimming provides a powerful workout for both body and brain. Even vigorous walking in the shallow end offers resistance and pressure that improve circulation and challenge muscles, stimulating blood flow to both body and brain, according to Professor Hirofumi Tanaka of the University of Texas at Austin.

Several Food Hacks That Really Make a Difference are highlighted. Firstly, Cooked Tomatoes are Healthier. Heating tomatoes, such as in pasta sauce or soup, breaks down their structure, making lycopene – a potent antioxidant – more bioavailable. Pairing cooked tomatoes with a fat source like olive oil further boosts absorption, as lycopene is oil-soluble. Cooking and blending tomatoes significantly increases lycopene yield (e.g., 100g of tomato sauce delivers roughly 50mg of lycopene compared to 5-10mg from a salad).

Secondly, Add Turmeric to Your Food Every Day. Known for its therapeutic reputation, turmeric may boost mood, sharpen memory, and ease aches. Tips for incorporating it include stirring a teaspoon into soups and stews (sautéing in oil first), making a golden latte (with black pepper and ginger), adding a pinch to scrambled eggs or egg mayonnaise, and mixing it into rubs and marinades. Always cook turmeric with a little oil or fat and a pinch of black pepper to enhance the absorption of its active ingredient, curcumin.

Thirdly, Pick a Polyphenol-Rich Red Wine. Consumed in small quantities with food, red wine can protect the heart, regulate blood sugar, and enhance gut bacteria diversity. This is attributed to high concentrations of polyphenols from grape skins and seeds, known for antioxidant and anti-inflammatory properties. Wines from thicker-skinned grapes like Cabernet Sauvignon, Syrah, Malbec, and Tannat are richer in polyphenols. Avoiding heavily processed wines is advised. Additionally, Drizzle on Extra Virgin Olive Oil. A Spanish study found daily consumption of about one and a half tablespoons of EVOO reduced the likelihood of dying from cardiovascular disease by nearly 50 percent compared to refined olive oil users, due to its polyphenols. EVOO also acts as a brain tonic, improving memory, brain connectivity, and blood-brain barrier integrity in adults with mild cognitive impairment. Aim for 2 tablespoons (30ml) daily. Another brief but significant dietary tip involves Cold Cooked Potatoes, identified as a rich source of fibrous prebiotics that are gentler on blood sugar and beneficial for gut health.

Laugh Out Loud for genuine health benefits beyond morale boosting. Laughter draws in oxygen-rich air, stimulates the lungs and heart, relaxes the body, and increases endorphin production, promoting pain relief and emotional connection. Shared laughter also acts as a powerful social glue. Oxford University research found that laughing together strengthens social bonds. A study noted that 15 minutes of laughing at comedy videos increased pain tolerance by ten percent, with deep, uninhibited laughter showing the biggest benefit. Laughter also boosts brain power, improving mood and memory, and increasing gamma brainwave activity, associated with high-level cognitive processes. A large Japanese study linked daily laughter to a 20 percent reduced risk of heart disease.

Try Nasal Breathing, a simple yet powerful health habit. Breathing through the nose increases oxygen uptake, maintains gum health, strengthens immune response, and may sharpen memory by filtering, humidifying, and warming air before it reaches the lungs. This process improves lung function, protects respiratory health, and enhances cognitive function. Tips include clearing nostrils with saline spray, keeping lips gently closed, taping lips (with caution for severe congestion), and humming for 5-10 seconds to flush sinuses and boost immunity.

Try Tai Chi for a gentle yet effective exercise. This ancient Chinese martial art improves balance, supports the immune system, benefits heart health, and targets visceral fat. Movements like "Commencement" (raising and lowering arms with breath coordination) calm the mind, promote good posture, and introduce breath control. "Parting the wild horse's mane" (alternating steps with hand movements) enhances coordination and balance. Videos are available for learning the techniques.

Take Vitamin D as a vital supplement. Well-known for bone health, low vitamin D levels can also impair immunity, mood, inflammation control, and accelerate cognitive decline. The NHS recommends a daily 10mcg (400 IU) supplement from October to March for most people, with D3 (cholecalciferol) being the more effective form, and plant-based D3 from lichen available for vegans. As vitamin D is fat-soluble, it's best taken with a meal containing healthy fats. Various formulations like oil suspensions, liquid drops, chewable tablets, and sprays cater to different needs and absorption preferences. Always choose third-party tested or reputable body-approved supplements to ensure stated dosage and freedom from contaminants.

Eat Your Food More Slowly to gain surprising perks. The modern habit of speed eating, often involving multitasking and quick consumption, contrasts with the benefits of mindful eating. Eating slowly can aid weight maintenance, stabilize blood sugar, and reduce the risk of type 2 diabetes, high cholesterol, and high blood pressure. Tried-and-tested methods include putting down your fork between bites, using your non-dominant hand, chewing each bite 20-30 times, drinking water between mouthfuls, using chopsticks or smaller utensils, listening to slow, relaxing music, avoiding distractions, and setting a timer or using a mindful eating app.

Get Skipping with plyometric exercises like hopping, skipping, and jumping, which are powerful tools for improving health and longevity. These explosive movements engage rapid stretch and shortening of muscles, placing significant load on bones and stimulating bone growth; a Hong Kong study showed teenage girls who skipped an hour a week had higher bone density. The synchronized arm and leg movements, rhythm maintenance, and balance challenge also stimulate brain regions associated with motor control, memory, and attention. Starting with short bouts and practicing "soft landings" with bent knees and even weight distribution is crucial, especially for those unfit or prone to joint issues.

Get in Pole Position with Nordic walking, a rhythmic exercise that uses specially designed poles to engage the arms and upper body. It is gaining popularity for improving physical and mental health, with evidence showing benefits for blood pressure, cholesterol, glucose levels, and weight management. It increases oxygen uptake and metabolic rate without stressing joints, making it suitable for individuals with arthritis, obesity, or mobility limitations. Dr. Jennifer Reed recommends starting slowly and gradually increasing to 150 minutes a week, aiming for techniques like big strides, opposite arm-leg swing, loose pole grip, pushing down on poles to propel forward, and maintaining an upright posture with relaxed shoulders.

Dr. Michael Mosley's enduring legacy, encapsulated in his "Just One Thing" philosophy, continues to offer accessible, science-backed pathways to improved health and well-being. The new TV series of "Just One Thing," presented by Zoe Ball, Clive Myrie, and Roman Kemp, on BBC One from Monday, March 23, further extends his invaluable advice, allowing more people to benefit from the profound impact of small, consistent changes.
