How Seasons Affect Kidney Health in Post-Menopausal Females

Intense heat stress on the body can reduce kidney function. A recent study reported that blood markers of kidney function are lower among people in hotter climates. However, these data did not consider physical activity, food intake, fluid intake, time spent outdoors, or exposure to sunlight. Therefore, the investigators invite participants to help determine whether there are seasonal changes in kidney function biomarkers. This will also help the investigators understand if physical activity, food intake, fluid intake, time spent outdoors, or exposure to sunlight affect kidney function biomarkers between seasons. The investigators are studying female adults post-menopause since they are an understudied group.
