Myth: arm position doesn't matter during a blood pressure check. Johns Hopkins researchers found an unsupported arm can raise systolic readings by about 6.5 mmHg, potentially affecting a hypertension diagnosis.
Take: Rest your arm on a table at heart level, back supported, feet flat, and sit quietly for 5 minutes before measuring.
Myth: artery plaque is only an older person's problem. Among 16,000 apparently healthy adults, more than half had signs of atherosclerosis, and about 1 in 13 people aged 18 to 29 already had detectable plaque.
Take: Don't wait for symptoms to think about your arteries. From your 20s on, manage blood pressure, cholesterol, blood sugar and smoking — far cheaper than fixing damage later.
Myth: with type 2 diabetes you only need to watch your glucose. Within 5 years of diagnosis, the risk of chronic kidney disease, heart failure or death is high — and CKD tends to appear before heart failure.
Take: After a diabetes diagnosis, don't just check glucose. Get regular kidney function and urine protein tests, and pay attention to heart symptoms.
Myth: there's nothing you can do about brain aging. People who followed the MIND diet more closely showed slower brain shrinkage and less grey matter loss — equal to about 2.5 years of delayed brain aging. Berries and poultry were linked to healthier brain changes; sweets and fried fast food were not.
Take: Start today: swap one sweet or fried item for a handful of berries or a serving of poultry. Consistency beats occasional 'brain food'.
Myth: what you eat has nothing to do with mood. In a small preliminary study, people with depression who sharply cut ultra-processed foods saw notable symptom improvement, possibly by reducing gut damage and chronic inflammation.
Take: No need to go cold turkey. Start by replacing one snack or sugary drink a day with whole foods, and see how you feel over a few weeks.
Myth: cardiovascular disease strikes out of nowhere. Research shows functional decline begins many years before clinically apparent cardiovascular events.
Take: Don't ignore a slow drop in stamina, walking speed or daily activity — it may be an early heart signal worth a doctor's evaluation.
Myth: only paid brain-training programs prevent cognitive decline. A large study shows reading, socializing and puzzles help preserve cognitive health, while short intensive training isn't very practical.
Take: Build thinking into daily life: read a few pages, chat with people, do puzzles or chess — more sustainable than a short training course.
Myth: cannabis is just a relaxing, low-risk habit. A review of over 265,000 people found cannabis use linked to higher rates of both committing violence and being a victim — though this doesn't prove cannabis itself is the cause.
Take: Don't treat cannabis as a harmless stress reliever. If you use it to cope with mood or stress, talk to a doctor or counselor about safer options.
Myth: Alzheimer's is pure luck and can't be prevented. Experts say a solid night's sleep and playing chess or Sudoku can actually lower your risk, and humming is one of the simplest ways to ease anxiety.
Take: Do two things tonight: aim for about 7 hours of sleep, and spend 10 minutes on Sudoku or humming along to music before bed.
Myth: memory loss with age means Alzheimer's. Research shows normal aging and Alzheimer's reshape brain communication in distinct patterns, so disease-related changes can be told apart from normal aging.
Take: Occasional forgetfulness is fine, but if memory or thinking changes clearly affect daily life, get evaluated early instead of blaming 'old age'.
