Guidelines recommend that women starting hormone therapy do so before age 60 and within 10 years of menopause onset. Starting later may raise the risks of heart attack, stroke, or dementia. Women who start hormone therapy at 70 or older face even greater cardiovascular risks.
A variety of disparate factors can speed up people’s biological aging, which describes how well their body functions (in comparison to chronological aging). Drivers of aging include ultraviolet light, stress, smoking, obesity, radiation, and loneliness and social isolation.
