Strength Training for Longevity: What the Evidence Can and Cannot Say
Strength training can support healthy ageing, but it is not a proven life-extension treatment or a substitute for medical care. The evidence is measured.
Exercise and Bone Density After 50: What the Science Shows
Weight-bearing exercise can help maintain bone density after 50, but not every type works equally. Here is what the evidence shows about impact, resistance, and safety.
Perimenopause at Midlife: Transition, Not a Diagnosis
Perimenopause can disrupt sleep, mood, and cycles years before the final period, but symptoms vary widely and testing has limits. Context matters.
Progesterone After 40: Brain Health, Sleep, and the Evidence Gap
Progesterone after 40 affects sleep, brain function, and metabolism, but the evidence base for those non-reproductive effects still has surprising gaps.
Fasting and Muscle Mass: What the Evidence Actually Shows
Intermittent fasting does not automatically cost muscle mass, but protein intake, training, and deficit size matter more than the eating window alone.
Progressive Muscle Relaxation: Helpful, Not Therapy
Progressive muscle relaxation may ease stress for some adults, but evidence is mixed and it should not replace care for anxiety, pain, or trauma symptoms.
RDW Blood Tests: An Ageing Signal, Not a Diagnosis
RDW can add context to blood-count results and ageing-risk research, but it is a non-specific signal that needs careful clinical interpretation.
Sleep Inertia After 50: Morning Fog Is Not Laziness
Sleep inertia can make mornings feel foggy after 50, but sleep timing, sleep debt, medicines, and safety matter more than willpower or blame.
Allostatic Load: Stress Biology, Not a Wellness Score
Allostatic load can frame how chronic stress affects the body, but it is a research construct, not a personal score or diagnosis. Context matters.
Plant Sterols and Cholesterol: Useful, Not a Cure-All
Plant sterols can modestly lower LDL cholesterol, but products, dose, diet context, medicines, and rare genetic risks decide how useful they are.
