Nordic Walking After 60: Poles Help, Not a Miracle
Nordic walking can make a familiar walk harder and more useful after 60, but the research supports modest fitness gains, not miracle claims.
Fasting Insulin Tests: Useful Signal, Not Diagnosis
Fasting insulin has become a favourite marker in metabolic-health circles because it seems to promise an earlier warning than glucose. The idea is plausible: insulin can rise for years whilst fasting glucose still looks normal. The harder question is whether one fasting insulin result tells an individual what to do next. Usually, it does less … Read more
Self-Compassion for Stress: Useful Skill, Not Therapy
Self-compassion can soften stress and self-criticism, but the evidence supports it as a practical skill rather than a stand-alone treatment.
Polyphenols and Gut Health: Useful Signal, Not a Cure
Polyphenols in berries, coffee, tea, and beans may shape gut microbes, but the evidence favours food variety over pills or miracle claims for now.
Uric Acid Testing: Gout Signal, Not Longevity Score
Uric acid can flag gout and kidney-stone risk, but evidence does not support treating a silent high result as a stand-alone longevity target today.
Testosterone Therapy After 50: Benefits and Blind Spots
Testosterone therapy has become a midlife shorthand for energy, muscle, sex drive, and masculine decline. The biology is more specific. Testosterone matters for the brain, blood, bone, muscle, and sexual function, but treatment is meant for men with symptoms plus repeatedly low levels, not for every man who feels older than he used to. Testosterone … Read more
Night Noise and Sleep: Small Sounds, Real Disruption
A bedroom can sound quiet enough and still keep the sleeping brain on duty. Night-time noise does not need to wake you fully to matter. The evidence is clearer for repeated peaks, traffic bursts, and aircraft noise than for every small household sound, but the mechanism is straightforward: the auditory system remains partly open during … Read more
Zinc Supplements for Immunity: Signal, Not Cold Armour
Zinc matters for immune function, but supplements mainly help when intake is low. The evidence for colds, older adults, and safety is narrower.
Tai Chi After 60: Balance Practice, Not Fall Insurance
Tai chi can improve balance and may reduce falls in older adults, but it works best as structured practice, not as a guarantee against injury.
Early Dinner for Glucose Control: Useful, Not a Cure
Eating earlier may modestly help glucose control, but the evidence supports timing as a small metabolic lever, not a stand-alone treatment for everyone.
