Healthspan in American English: sleep first, supplements last

Longevity for US readers starts with a wake time you can keep, darkness at night, and blood-pressure context with your PCP — not a miracle stack.

Healthspan is years you can use

Lifespan is how long you live. Healthspan is how long you stay capable — walking, sleeping, thinking, and recovering. US coverage of longevity often jumps to gadgets. The US desk keeps the order: sleep, movement, food, then a clinician for biomarkers.

A stable wake time, a darker bedroom, and less late caffeine are boring on purpose. They are also the habits that still show up in sleep-medicine reviews. Blue-light glasses and magnesium are optional. A phone in the pillow is not.

• Same wake time, including weekends when you can.
• Keep the bedroom cooler and darker; park the phone outside arm’s reach.
• Ask your PCP which numbers matter for you — blood pressure, lipids, glucose — instead of ordering a mystery panel online.

When to stop reading and call

Loud snoring with witnessed pauses, chest pain, sudden weakness, or a new severe headache is not a longevity protocol. Call 911 or your local emergency number. The magazine explains evidence. It does not triage you.
