What the magnesium and sleep trials really tested, why glycinate labels mislead, safe upper limits (NHMRC, NIH, EFSA), medicine interactions and better sleep first steps.
How sleep supports recovery from exercise, what studies show, how age changes it, a training-day sleep plan and the mistakes that cost sleep.
Which sleep changes are a normal part of ageing and which are worth a GP visit, plus the simple habits with the best evidence and a two-week sleep reset.
What normally changes in sleep with age, how to tell normal from a problem worth checking, why it matters for recovery, and a practical plan.
