How branding and peer pressure keep kids hooked on energy drinks

Children and adolescents in North East England still find energy drinks easy to access despite a voluntary UK ban, drawn by taste, price, and powerful marketing. Hydration drinks like PRIME are viewed as “healthier,” even though young consumers often misunderstand their ingredients and health impacts.

Women gain stronger heart protection from exercise than men, study reveals

Researchers analyzing over 85,000 UK Biobank participants found that women gain greater cardiovascular benefits from physical activity than men, needing only half the exercise to achieve similar reductions in coronary heart disease and mortality risk. The study underscores the importance of sex-specific guidelines for CHD prevention.
