Women reach heart health goals with less exercise than men, new study suggests

Women may need less exercise than men to gain similar protection against coronary heart disease, according to a new study published in Nature Cardiovascular Research. The findings come from an observational study of more than 85,000 adults in the United Kingdom who were followed for about seven years. Researchers used data from a one-time “snapshot” — a weeklong period of wrist-worn fitness tracker measurements — to examine how physical activity relates to heart disease risk and death rates. The study found that women who got around four hours of moderate exercise each week lowered their risk of coronary heart disease by about 30%. However, men needed nearly twice as much — about eight hours of similar activity — to achieve the same level of heart protection. Additionally, women who alread
